Solution Overview
Problem
Conventional AI systems face significant challenges in reducing processor learning time during the training phase, as the evaluation of weights across numerous node combinations becomes excessively time-consuming, limiting predictive performance due to uniform update rates that fail to prioritize important areas effectively.
Innovation Solution
The implementation of differential update rates for weights assigned to different node inputs or input subsets during the learning phase, allowing for varying update rates based on segmentations of training data, network nodes, or identified features, thereby focusing on critical areas and reducing overall learning time.

Engineering Contradiction Analysis
1Productivity
If uniform update rates are applied to all node inputs during training, then the training process is simple to implement, but the learning time becomes excessively long and predictive performance is limited
Solution Approach 1:
The patent applies different update rates to different node inputs based on their importance or characteristics. Specifically, inputs that are determined to be more important or have higher variance receive larger update rates, while less important inputs receive smaller update rates. This local differentiation of update quality resolves the contradiction by accelerating learning for critical inputs without unnecessarily slowing down updates for less important ones, thereby reducing overall training time while maintaining or improving predictive performance.
Solution Approach 2:
The patent dynamically adjusts update rates during the training process based on the current state of the network and the importance of different inputs. The update rates are not fixed but adapt throughout training, allowing the system to optimize learning speed for each input based on its contribution to prediction accuracy. This dynamic approach enables the system to achieve faster convergence compared to static uniform update rates.
2Measurement precision
If more intensive training is applied to important areas with differential update rates, then predictive performance and accuracy improve, but the complexity of the training process increases
Solution Approach 1:
The patent implements local quality by assigning different update rates to different inputs based on their importance. The system identifies which inputs contribute most to prediction accuracy and applies more intensive training (larger update rates) to those specific inputs. This targeted approach improves prediction accuracy by focusing computational effort where it matters most, while avoiding unnecessary complexity in training less important inputs.
Solution Approach 2:
The patent changes the training parameter (update rate) based on the importance of each input. By modifying this key parameter differentially across inputs, the system achieves better prediction accuracy without requiring fundamental changes to the network architecture or training framework. The parameter change approach maintains relative simplicity while improving performance.
3Adaptability or versatility
If the number of system inputs increases for training batches, then the model can process more complex data, but the processor learning time increases exponentially
Solution Approach 1:
The patent applies local quality by differentiating update rates across the increased number of inputs based on their individual importance. Rather than treating all inputs uniformly (which would require exponentially more time as inputs increase), the system identifies and prioritizes the most important inputs with higher update rates. This allows the model to handle complex multi-input data effectively while avoiding exponential training time increases by focusing computational resources on critical inputs.
