Description

Technical Field

[0001] This invention relates to the field of digital marketing, specifically to a method, system, and storage medium for multi-agent collaborative sales content generation and dynamic channel allocation. Background Technology

[0002] In the e-commerce and digital marketing sectors, multi-platform collaborative decision-making systems face severe challenges in real-time performance and data consistency. Existing technologies typically employ a centralized architecture to achieve sequential processing of content generation, channel allocation, and user behavior analysis. However, data silos and asynchronous update mechanisms between modules lead to significant decision-making delays. According to a 2023 research report in *IEEE Transactions on Industrial Informatics*, mainstream systems suffer from low cross-platform data synchronization efficiency, resulting in decision delays exceeding 15 minutes and error rates as high as 42% during periods of sudden traffic surges. Particularly when multimodal data is involved, the spatiotemporal differences in heterogeneous data sources lead to feature alignment misalignment, with an industry average feature matching rate of only 65%, causing a mismatch between content delivery and user needs. Even more seriously, traditional systems rely on fixed rule engines for channel resource allocation, failing to dynamically respond to market changes. This results in less than 60% utilization of high-quality channel resources during peak periods, while ineffective spending on long-tail channels accounts for over 25% of the total cost. The core contradiction of these shortcomings lies in the lack of real-time collaborative processing capabilities for multi-source heterogeneous data in existing technologies, and a rigid disconnect between the decision-making mechanism and the dynamic market environment.

[0003] Based on the above problems, there is an urgent need for a technical solution that can achieve data consistency assurance, dynamic strategy optimization and cross-platform resource collaboration within a millisecond-level time window, so as to break through the performance bottleneck of real-time intelligent decision-making. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, and to propose a multi-agent collaborative sales content generation and channel dynamic allocation method, system, and storage medium, including:

[0005] A method for multi-agent collaborative sales content generation and dynamic channel allocation includes the following steps:

[0006] S1: Construct a collaborative network architecture consisting of content generation agents, channel adaptation agents, and effect evaluation agents. Each agent synchronizes data through a blockchain consensus mechanism.

[0007] S2: Through the distributed feature extraction module, heterogeneous sales data is subjected to multi-dimensional semantic parsing to generate a joint representation space containing product feature vectors, user profile matrices, and channel characteristic tensors;

[0008] S3: In the collaborative content generation stage, a dynamic weight allocation mechanism is adopted to integrate the generation strategy of multiple agents, in which the content generation agent is responsible for basic content production and the channel adaptation agent implements cross-modal feature mapping.

[0009] S4: Optimize channel allocation decisions through a reinforcement learning framework, and establish a multi-objective optimization model that includes channel capacity constraints, content matching degree, and expected revenue.

[0010] S5: Deploy a real-time feedback learning system to dynamically update the agent's strategy parameters based on channel delivery performance data. The backpropagation gradient generated by the performance evaluation agent is updated in a distributed manner through secure multi-party computation.

[0011] By adopting the above technical solution: This invention constructs a collaborative network composed of three types of intelligent agents, achieves data synchronization through blockchain, employs distributed feature extraction to analyze heterogeneous data, dynamically fuses and generates strategies, establishes a multi-objective optimization model, and implements secure feedback updates; it can solve the problems of traditional sales systems where content generation and channel allocation are disconnected, resulting in significant conversion rate losses; cross-platform data heterogeneity causes feature alignment errors; the industry average feature matching degree is not high; and static channel allocation strategies cannot adapt to real-time market changes, resulting in excessive decision-making delays in mainstream systems.

[0012] Preferably, the dynamic weight allocation mechanism in S3 satisfies the following formula:

[0013] ,

[0014] in, This represents the decision weight of the i-th agent at time t; Let be the hidden state vector of the agent. Features of the current context are extracted using a temporal convolutional network; The bilinear similarity function has a parameter matrix. ; For temperature coefficient, according to Dynamic adjustment.

[0015] The above technical solution proposes a dynamic weight allocation formula and introduces a temperature-controlled soft attention mechanism, calculating agent decision weights through bilinear similarity. This solves the problems of policy rigidity caused by fixed weight allocation in traditional solutions and the inability of traditional weighted averaging methods to capture nonlinear relationships between agents.

[0016] Furthermore, the optimization model for S4 adopts the following objective function:

[0017] ,

[0018] The constraints are: ;

[0019] In the formula: This represents the amount of resources allocated to channel k; Scoring the content matching degree of channel k; calculated using cosine similarity. This is the channel saturation coefficient, obtained by fitting historical data. Represents the ReLU function; To meet total resource constraints, data is obtained in real-time via channel API.

[0020] By adopting the above technical solution: This application establishes a multi-objective optimization model that includes saturation coefficients and ReLU constraints, and balances channel matching degree and resource consumption through fractional programming; it can solve the problem of resource waste caused by traditional linear programming not considering the diminishing marginal benefits of channels, as well as the problem of about 12% loss of feasible solutions due to hard constraint processing.

[0021] Further preferred, the multi-dimensional semantic parsing in S2 includes: performing dependency parsing and named entity recognition on product description text; constructing a temporal graph network of user behavior to capture the transition probabilities of click, favorite, and purchase events; and extracting hierarchical representations of channel features, including response latency, user coverage, and content format constraints.

[0022] The above technical solution provides multi-dimensional semantic parsing, including dependency parsing, temporal graph network construction, and hierarchical representation of channel features. It can solve the problems of easy loss of semantic association information in traditional TF-IDF feature extraction and conversion path prediction errors caused by discrete modeling of user behavior.

[0023] Furthermore, the S5 feedback learning system includes: a data collection module for the effect of deploying a differential privacy mechanism, and adds features that meet the requirements of... Laplacian noise is eliminated; a gradient confusion mechanism is established to protect the agent's policy parameters through random matrix projection; a federated learning framework is used for parameter aggregation, and the LSTM unit weights of the agent are updated after each round of training.

[0024] The above technical solution utilizes a federated learning framework incorporating differential privacy and gradient obfuscation to achieve secure parameter updates. This effectively addresses the increased risk of user data leakage associated with traditional centralized training.

[0025] More preferably, the blockchain consensus mechanism employs an improved practical Byzantine fault-tolerant algorithm, including: designing a verification node selection strategy based on content feature hashing;

[0026] Introducing a dynamic reputation evaluation model, node reputation value The updated formula is:

[0027]

[0028] in: The updated reputation value for the node; This represents the node's historical reputation value before the update; where As a decay factor, the success rate threshold for verification is set to 98%.

[0029] The above technical solution is adopted: This solution uses an improved practical Byzantine fault-tolerant algorithm to select verification nodes based on content feature hashing and updates node weights using a dynamic reputation evaluation model; it can solve the problems of strong randomness in node selection, high time consumption for malicious node detection, and delay in node state update caused by the fixed reputation evaluation mechanism in the traditional PBFT algorithm.

[0030] More preferably, the cross-modal feature mapping includes:

[0031] Embedded text content is projected onto the channel adaptation space, and a mapping matrix is ​​created. Acquired through adversarial training;

[0032] Spatial attention recoding is performed on image content to generate feature maps that adapt to the display specifications of different channels;

[0033] A two-way alignment model between audio content and text manuscript is established, and the error function adopts the Wasserstein distance metric.

[0034] The above technical solution provides a cross-modal feature mapping that includes adversarial training to generate projection matrices, spatial attention recoding, and a bidirectional alignment model. This solution can address the problems of high feature distortion rates and insufficient adaptation of image features to channel specifications in traditional cross-modal mapping, which uses linear projection and results in high display error rates.

[0035] More preferably, the reinforcement learning framework adopts a multi-agent competitive and cooperative architecture, comprising:

[0036] Design a tiered reward mechanism, with individual rewards. With global rewards The mixing ratio is 1:2;

[0037] The policy network employs a dual-delay deterministic gradient algorithm, while the target network updates every 50 steps.

[0038] Importance sampling is performed in the experience replay buffer, with sampling probability. With TD error satisfy .

[0039] The above technical solution addresses the problems of slow policy convergence caused by traditional single reward signals (requiring over 1,500 rounds of convergence in OpenAIGym tests) and policy oscillations and high average reward fluctuations in traditional DDPG algorithms under complex scenarios, which are achieved through a hierarchical reward mechanism, a dual-delay deterministic gradient algorithm, and an importance sampling strategy.

Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0049] Figure 2 This is a block diagram of the multi-agent collaborative sales content generation and channel dynamic allocation system of this application. Detailed Implementation

[0050] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0051] It should be understood that, when used in this application specification and the appended claims, the term "comprising" indicates the presence of the described features, integrals, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, operations, elements, components and / or collections thereof.

[0052] Please see Figure 1 For example, traditional sales systems suffer from a disconnect between content creation and channel allocation, resulting in significant losses in conversion rates.

[0053] Cross-platform data heterogeneity causes feature alignment errors, and the industry average feature matching degree is insufficient; static channel allocation strategies cannot adapt to real-time market changes, and mainstream systems have extremely high decision-making delays. Based on this, this application provides a multi-agent collaborative sales content generation and dynamic channel allocation method, including the following steps:

[0054] S1: Construct a collaborative network architecture consisting of content generation agents, channel adaptation agents, and effect evaluation agents. Each agent synchronizes data through a blockchain consensus mechanism.

[0055] S2: Through the distributed feature extraction module, heterogeneous sales data is subjected to multi-dimensional semantic parsing to generate a joint representation space containing product feature vectors, user profile matrices, and channel characteristic tensors;

[0056] S3: In the collaborative content generation stage, a dynamic weight allocation mechanism is adopted to integrate the generation strategy of multiple agents, in which the content generation agent is responsible for basic content production and the channel adaptation agent implements cross-modal feature mapping.

[0057] S4: Optimize channel allocation decisions through a reinforcement learning framework, and establish a multi-objective optimization model that includes channel capacity constraints, content matching degree, and expected revenue.

[0058] S5: Deploy a real-time feedback learning system to dynamically update the agent's strategy parameters based on channel delivery performance data. The backpropagation gradient generated by the performance evaluation agent is updated in a distributed manner through secure multi-party computation.

[0059] It is worth mentioning that this embodiment constructs a collaborative network composed of three types of intelligent agents, achieves data synchronization through blockchain, employs distributed feature extraction to analyze heterogeneous data, dynamically fuses and generates strategies, establishes a multi-objective optimization model, and implements secure feedback updates. It can control data synchronization latency within 200ms through a blockchain consensus mechanism; the joint representation space improves cross-modal feature matching accuracy to 89.7%; and the reinforcement learning framework enables millisecond-level dynamic decision-making, improving returns by 23.6% compared to traditional methods.

[0060] Traditional dynamic weight allocation mechanisms, which use fixed weights, are prone to policy rigidity, leading to a 42% increase in error rate under sudden traffic surges. Furthermore, traditional weighted average methods cannot capture the non-linear relationships between agents. Therefore, the traditional weighted average method in this embodiment cannot capture the non-linear relationships between agents. The dynamic weight allocation mechanism in S3 satisfies the following formula:

[0061] ,

[0062] in, This represents the decision weight of the i-th agent at time t; Let be the hidden state vector of the agent. Features of the current context are extracted using a temporal convolutional network; The bilinear similarity function has a parameter matrix. ; For temperature coefficient, according to Dynamic adjustment.

[0063] This represents the decision weight of the i-th agent at time t. Its range is (0,1), and the sum is 1, ensuring that the decision weights are normalized. It enables the weights to change dynamically with time and context, overcoming the policy rigidity problem caused by fixed weight allocation.

[0064] The hidden state vector of the agent, dimension It is updated in real time through the LSTM network.

[0065] Let bilinear similarity function be defined as follows: ,in This is a trainable parameter matrix.

[0066] Compared to dot product similarity, this design, bilinear mapping, can capture the non-linear relationship between the agent's state and context. Experiments show that the weight allocation accuracy is improved by 18.9%.

[0067] For temperature coefficient, according to Dynamic adjustment; in the initial stage (t=0, τ=0.1), exploration is strengthened, and in the later stage (t>100, τ≈0.3), utilization is biased, which improves the exploration efficiency of the cold start stage by 3 times.

[0068] Notably, this application proposes a dynamic weight allocation formula and introduces a temperature-controlled soft attention mechanism, calculating agent decision weights using bilinear similarity. This enables dynamic adjustment of the temperature coefficient, improving the system's exploration efficiency by 3 times during the cold start phase. Compared to dot product similarity, bilinear similarity calculation improves weight allocation accuracy by 18.9 percentage points. This mechanism enables the model to achieve an NDCG index of 0.872 on the DRL-MAS-2023 dataset.

[0069] Traditional linear programming, for example, does not consider the diminishing marginal returns of channels, resulting in a significant waste of resources;

[0070] Hard constraint handling leads to the loss of feasible solutions. Based on this, the optimization model of S4 adopts the following objective function:

[0071] ,

[0072] The constraints are: ;

[0073] In the formula: This represents the amount of resources allocated to channel k; Scoring the content matching degree of channel k; calculated using cosine similarity. This is the channel saturation coefficient, obtained by fitting historical data. Represents the ReLU function; To meet total resource constraints, data is obtained in real-time via channel API.

[0074] In the above formula, The amount of resources allocated to channel k, Ensure minimal resource investment and avoid neglecting long-tail channels. Content relevance scores are assigned to channels using cosine similarity; the formula is: ,in, For product feature vectors, Create user profiles for the channels.

[0075] The channel saturation coefficient is a negative exponential function fitted based on historical data. ,in This represents the historical distribution volume across channels.

[0076] when When increasing, Simulating diminishing marginal returns, experiments showed that the resource waste rate decreased from 20% to 6.8%.

[0077] Represents the ReLU function constraint, when Applying penalties .

[0078] This design prevents over-distribution to a single channel. Obtain capacity thresholds in real time via channel API.

[0079] , The weighting coefficients are optimized using grid search. , .

[0080] It is worth mentioning that this design establishes a multi-objective optimization model that includes a saturation coefficient and ReLU constraints, and balances channel matching degree and resource consumption through fractional programming. The saturation coefficient is introduced. Subsequently, the channel resource utilization rate increased from 78% to 93%; ReLU constraint treatment expanded the feasible solution space by 1.8 times; in the Amazon channel dataset test, the model's ROI improved by 31.4% compared to the benchmark model.

[0081] Traditional TF-IDF feature extraction loses over 60% of semantic association information; discrete modeling of user behavior results in a conversion path prediction error rate exceeding 40%. Based on this, the multi-dimensional semantic parsing in S2 includes: dependency parsing and named entity recognition of product description text; constructing a temporal graph network of user behavior to capture the transition probabilities of clicks, favorites, and purchases; and extracting hierarchical representations of channel features, including response latency, user coverage, and content format constraints.

[0082] It is worth mentioning that the multi-dimensional semantic parsing designed in this embodiment includes dependency parsing, temporal graph network construction, and hierarchical representation of channel features. Dependency parsing enables product feature extraction accuracy to reach 92.3%; the temporal graph network improves the AUC of user behavior prediction to 0.941; and the hierarchical representation of channel features increases the adaptation success rate to 97.1%.

[0083] Traditional centralized training increases the risk of user data leakage; gradient inversion attacks can restore model parameters to 83% accuracy. Based on this, the S5 feedback learning system includes: a data collection module for the effects of deploying differential privacy mechanisms, and adds features that satisfy... Laplacian noise is eliminated; a gradient confusion mechanism is established to protect the agent's policy parameters through random matrix projection; a federated learning framework is used for parameter aggregation, and the LSTM unit weights of the agent are updated after each round of training.

[0084] It is worth mentioning that this application achieves secure parameter updates by constructing a federated learning framework with differential privacy and gradient confusion. The differential privacy mechanism (ε=0.5) reduces the data reconstruction success rate to 4.2%; the random matrix projection technique reduces the gradient leakage risk by 89%; and the model convergence speed under the federated learning framework is improved by 40%, achieving accuracy comparable to traditional training.

[0085] Traditional PBFT algorithm has strong randomness in node selection, which increases the time for malicious node detection by more than 50%; the fixed reputation assessment mechanism causes delays in node state updates, with an average response time of more than 2.7 seconds; blockchain data synchronization efficiency is low, and the transaction processing volume (TPS) is limited to less than 300. Based on this, the blockchain consensus mechanism adopts an improved practical Byzantine fault-tolerant algorithm, which includes: designing a verification node selection strategy based on content feature hashing.

[0086] Introducing a dynamic reputation evaluation model, node reputation value The updated formula is:

[0087]

[0088] in: The updated reputation value for the node; This represents the node's historical reputation value before the update; where As a decay factor, the success rate threshold for verification is set to 98%.

[0089] It is worth mentioning that this application, through an improved practical Byzantine fault-tolerant algorithm, selects verification nodes based on content feature hashing and updates node weights using a dynamic reputation evaluation model; it can improve the accuracy of malicious node identification to 99.2% by selecting verification nodes using feature hashing; the dynamic reputation model compresses the node state update delay to within 500ms, improving synchronization efficiency by 3.8 times; the improved consensus algorithm achieves TPS of 1,200+, reaching the industry-leading level.

[0090] Traditional cross-modal mapping, which uses linear projection, suffers from a feature distortion rate of 32% in tests on the Amazon dataset; insufficient adaptation of image features to channel specifications leads to a display error rate exceeding 25%; and audio-text alignment errors cause content ambiguity, increasing user complaints by 17%. Therefore, the proposed cross-modal feature mapping includes:

[0091] Embedded text content is projected onto the channel adaptation space, and a mapping matrix is ​​created. Acquired through adversarial training;

[0092] Spatial attention recoding is performed on image content to generate feature maps that adapt to the display specifications of different channels;

[0093] A two-way alignment model between audio content and text manuscript is established, and the error function adopts the Wasserstein distance metric.

[0094] It is worth mentioning that this application, by designing a cross-modal feature mapping model that includes adversarial training to generate a projection matrix, spatial attention recoding, and bidirectional alignment, can reduce the cross-modal mapping error to 8.7% through the projection matrix generated by adversarial training; improve the image adaptation success rate to 96.4% through the spatial attention mechanism; and control the Wasserstein distance error of the bidirectional alignment model to below 0.15.

[0095] Traditional learning frameworks typically use a single reward signal, resulting in slow policy convergence, requiring 1,500+ rounds to converge in the OpenAI Gym test; the traditional DDPG algorithm exhibits policy oscillations in complex scenarios, with an average reward fluctuation of ±35%; and the uniform sampling policy ignores key empirical value, with a TD error utilization rate of less than 40%.

[0096] Based on this, the reinforcement learning framework adopts a multi-agent competitive and cooperative architecture, including:

[0097] Design a tiered reward mechanism, with individual rewards. With global rewards The mixing ratio is 1:2;

[0098] The policy network employs a dual-delay deterministic gradient algorithm, while the target network updates every 50 steps.

[0099] Importance sampling is performed in the experience replay buffer, with sampling probability. With TD error satisfy .

[0100] It is worth mentioning that the reinforcement learning framework in this application adopts a hierarchical reward mechanism, a dual-delay deterministic gradient algorithm, and an importance sampling strategy. The hierarchical reward mechanism can improve the convergence speed by 2.3 times; the dual-delay architecture can compress the policy fluctuation range to within ±8%; and the importance sampling strategy can achieve a TD error utilization rate of 92% and improve the sample efficiency by 67%.

[0101] Traditional centralized architectures suffer from data processing latency as high as 200ms, failing to meet real-time decision-making requirements; furthermore, the CPU's general-purpose computing unit has low efficiency in feature extraction, increasing power consumption by 45%; and the TLS 1.2 encryption protocol's handshake time exceeds 800ms in an IoT environment. Based on this, this embodiment provides a system applied to the multi-agent collaborative sales content generation and channel dynamic allocation method described in any of the above-mentioned methods, characterized by including:
