1Reliability
If supervised loss term is used for training neural networks to perform algorithmic tasks, then the training can be performed with standard supervised learning techniques, but the learning speed is slow and the model becomes brittle
Solution Approach 1:
The patent applies self-service by introducing a self-supervised loss term that enables the neural network to learn from its own intermediate representations and computational steps. The model generates its own training signals by comparing intermediate representations across different computational paths, allowing it to self-correct and improve without relying solely on external supervised labels, thereby accelerating training while maintaining generalization
Solution Approach 2:
The patent implements feedback mechanisms through the self-supervised loss term that continuously monitors and adjusts the neural network's intermediate representations. By comparing predicted intermediate states with actual computational steps and providing gradient feedback, the system enables faster learning convergence and improved model reliability without sacrificing training speed
2Measurement precision
If extensive preprocessing is applied to large datasets, then the model can process the data more accurately, but the computational resource consumption increases
Solution Approach 1:
The patent applies preliminary action by performing data augmentation and creating varied computational paths before the main training process. By pre-generating augmented datasets and establishing multiple computational routes in advance, the system prepares the neural network to handle diverse inputs without requiring extensive preprocessing during training, thus maintaining accuracy while reducing computational overhead
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting the complexity and depth of computational paths based on the input data characteristics. The system modifies computational parameters such as path depth, augmentation intensity, and loss weighting adaptively, allowing accurate processing of large datasets while optimizing computational resource consumption through parameter efficiency
3Adaptability or versatility
If the neural network is trained to perform algorithmic tasks using only supervised loss, then the training process is simpler, but the model cannot generalize well to new inputs
Solution Approach 1:
The patent applies universality by designing a multi-functional loss function that combines both supervised loss for task-specific learning and self-supervised loss for generalization. This composite loss structure enables the neural network to simultaneously learn algorithmic task performance and develop robust generalization capabilities, making the model adaptable to new inputs while managing training complexity through a unified framework
Solution Approach 2:
The patent introduces another dimension to the training process by adding the self-supervised learning dimension alongside traditional supervised learning. This dimensional expansion allows the model to learn from multiple objectives simultaneously - task accuracy from supervised loss and structural generalization from self-supervised loss - thereby improving adaptability without overwhelming complexity through hierarchical loss integration
