1Duration of action of moving object
If traditional machine learning models are used to generate audio files, then basic audio generation is possible, but generating longer audio files with natural music structure requires significant resources and technical expertise
Solution Approach 1:
The patent transforms the audio generation problem from the time domain to the frequency domain by applying Fourier transforms. This parameter transformation allows the model to operate on spectral representations rather than raw audio waveforms, reducing the computational complexity required to generate long-duration audio files while maintaining natural music structure
Solution Approach 2:
The patent introduces an intermediary spectral representation layer between the input prompt and the output audio. By converting audio to frequency domain representations (spectrograms) and processing through latent space transformations, the system mediates the complex generation task through intermediate computational stages that require fewer resources than direct time-domain generation
2Reliability
If traditional machine learning models are used, then audio generation can be performed, but errors occur due to human constraints and technical limitations
Solution Approach 1:
The patent implements self-service through automated hyperparameter optimization and adaptive training procedures. The system automatically adjusts learning rates, batch sizes, and model architecture parameters during training without human intervention, eliminating errors caused by suboptimal manual configuration and reducing reliance on technical expertise for achieving reliable generation
Solution Approach 2:
The patent incorporates feedback mechanisms through loss functions that compare generated spectral representations with target representations, and through evaluation metrics that guide model improvement. This automated feedback loop continuously reduces generation errors by adjusting model parameters based on performance measurements, eliminating the need for manual error correction
