Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional AI models are trained to recognize specific audio concepts, then the model can generate music with specific genre, style, or instrument characteristics, but the training process becomes complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-training a general music generation model on diverse music data before specializing it for specific audio concepts. This pre-trained model serves as a foundation that can be quickly adapted to specific genres, styles, or instruments without requiring extensive retraining, thus reducing both time and complexity while maintaining accuracy.
Solution Approach 2:
The patent implements local quality by selectively fine-tuning only specific parameters and layers of the neural network that are most relevant to the target audio concept. Instead of retraining the entire model, the method focuses computational resources on local adjustments in the network architecture that directly impact the representation of specific audio concepts, reducing overall training complexity.
2Adaptability or versatility
If the AI model is trained on diverse music data to maintain generalization ability, then the model can handle various audio concepts, but the model struggles to accurately represent specific audio concepts
Solution Approach 1:
The patent applies dynamics by implementing a flexible training regime that adapts the model's focus based on the specific task. The system can dynamically switch between maintaining generalization through diverse training data and achieving precision for specific concepts through targeted fine-tuning. This dynamic approach allows the model to optimize its performance characteristics based on the requirements of the specific audio concept being targeted.
3Measurement precision
If the entire neural network is retrained for specific audio concepts, then the model achieves high accuracy for those concepts, but the training time and computational resources increase significantly
Solution Approach 1:
The patent extracts and isolates only the critical parameters and layers of the neural network that are most influential for representing specific audio concepts. By identifying and extracting these key components, the method allows for targeted fine-tuning without the need to retrain the entire network, significantly reducing training time while maintaining accuracy for the specific concepts.
Solution Approach 2:
The patent applies partial action by fine-tuning only a subset of the model's parameters rather than the entire network. This selective approach focuses computational effort on the most impactful parameters while leaving other parts of the model unchanged, achieving high accuracy for specific audio concepts with minimal training time and computational resources.
4Ease of operation
If the AI model uses text prompts to generate music, then the model can create music based on descriptive input, but the text prompts cannot describe the user requirement exactly for specific concepts
Solution Approach 1:
The patent introduces an intermediary mechanism that bridges the gap between simple text prompts and precise audio concept representation. This intermediary layer translates user-friendly text descriptions into the specific parameter configurations needed for accurate music generation, allowing users to input simple text while achieving precise control over specific audio concepts through the model's fine-tuned parameters.

AI summary
The method involves configuring a pretrained text to music AI model that includes a neural network implementing a diffusion model. The process includes receiving audio sample data corresponding to a specific audio concept, generating a concept identifier token based on the audio sample data, adapting a loss function of the diffusion model based on the concept identifier token, selecting pivotal parameters in weight matrices in a self-attention layer of the neural network of the AI model based on the audio sample data, and further training the pivotal parameters of the AI model, to optimize the Al model for the specific audio concept.
