Description

Technical Field

[0001] The present invention relates to the field of intelligent evaluation technology, and in particular to an intelligent evaluation system for a cloud computing platform. Background Art

[0002] The existing intelligent assessment system has the following problems:

[0003] 1. Data leakage risk: The centralized storage model is vulnerable to network attacks, and hackers may steal sensitive assessment data through vulnerabilities; there is a risk of illegal access to cross-user data in a multi-tenant environment.

[0004] 2. Resource competition leads to response delays: In high-concurrency scenarios, insufficient computing resource allocation causes delayed evaluation results; when dynamic load fluctuates, service stability is difficult to guarantee.

[0005] 3. Insufficient system disaster recovery capabilities: Hardware failure or network interruption may lead to interruption of assessment services, and there is a lack of rapid recovery mechanism.

[0006] 4. Limited customization capabilities: Standardized evaluation models are difficult to meet the diverse needs of various industries (such as finance, healthcare, and other specialized scenarios). Algorithm updates and iterations rely on technical support from suppliers, leaving limited room for independent optimization.

[0007] 5. Difficulty in compatibility of heterogeneous systems: There are interface incompatibility issues when integrating with traditional business systems.

[0008] 6. Hidden costs are uncontrollable: Large-scale data storage and high-frequency computing costs may exceed your budget. Performance optimization requires the purchase of additional value-added services (such as GPU acceleration and dedicated network channels).

[0009] Therefore, there is an urgent need in this field for a technical solution that can solve the problems existing in the existing intelligent evaluation system.

[0123] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0124] The purpose of the present invention is to provide a technical solution that can solve the problems existing in the existing intelligent evaluation system.

[0125] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0128] The four-dimensional heterogeneous topology network module adopts a vertical fusion architecture consisting of a quantum key distribution layer, a federated learning computing layer, a cross-chain redundant storage layer, and a multimodal compliance engine to achieve closed-loop control that is secure, resilient, and compliant.

[0129] The dynamic load-aware neural network module builds a resource scheduling model based on a hypergraph neural network, capturing non-Euclidean spatial correlations between CPUs, GPUs, and bandwidth in real time. (Non-Euclidean spatial correlations refer to complex relationships between data elements that cannot be measured using traditional Euclidean geometric distances (such as straight-line distances). These relationships require the use of graph structures, hypergraphs, and other tools to model high-order, multi-dimensional nonlinear dependencies.) This enables nanosecond-level fault prediction and mitigation.

[0130] The privacy protection module, including a quantum-enhanced multi-party secure computing unit, uses a quantum random number generator to create a dynamic obfuscation circuit and injects quantum noise interference during the federated learning gradient update phase, preventing hackers from inferring the original data through differential attacks. The gradient in federated learning refers to the derivative of the loss function with respect to the model parameters, calculated by each participant based on local data during model training. This guides the update direction of the model parameters. In the federated learning framework, the gradient is the core carrier of multi-party collaborative training, carrying information about local data while avoiding the direct transmission of original data.
