Solution Overview
Problem
The high computational costs and inefficiencies in training Artificial Neural Network (ANN)-based AI models due to large training datasets, including increased time, resource requirements, and power consumption, are exacerbated by volatility in training data and methods, leading to slow converging or divergent training processes.
Innovation Solution
A method and system for weight matrix prediction in ANN-based AI models, where a candidate weight matrix is tested across multiple computing nodes in a distributed computing system, evaluating its applicability through a testing loss value to determine its suitability for a new formal iteration, thereby optimizing the training process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large scale training datasets are used to train ANN-based AI models, then training accuracy and model reliability are improved, but training time and computing resource consumption increase significantly
Solution Approach 1:
The patent applies preliminary action by performing a testing iteration before the formal training iteration to evaluate candidate weight matrices. This preliminary testing allows the system to predict which weight matrices are likely to converge well during formal training, thereby avoiding wasting time on weight matrices that would lead to poor convergence or local minimum traps, thus reducing overall training time while maintaining model reliability
Solution Approach 2:
The patent implements feedback by using the testing loss value obtained from testing iterations to guide the selection of weight matrices for formal training. The system evaluates the testing loss and uses this feedback information to determine whether to proceed with formal training on candidate weight matrices, creating a closed-loop control mechanism that optimizes training efficiency while ensuring model reliability
2Productivity
If more computing nodes are added to process training iterations in parallel, then training speed and productivity are improved, but system complexity and resource coordination overhead increase
Solution Approach 1:
The patent applies segmentation by dividing the training process into distinct phases: testing iterations and formal iterations. Each computing node independently performs these segmented tasks, reducing coordination overhead while maintaining parallel processing capabilities. The segmentation allows each node to work autonomously on weight matrix evaluation without requiring constant communication, thus improving training speed while managing system complexity
3Measurement precision
If extensive testing and evaluation of candidate weight matrices is performed, then weight matrix selection accuracy is improved, but computing resource consumption and training time increase
Solution Approach 1:
The patent applies partial action by performing testing iterations on a selected subset of candidate weight matrices rather than exhaustively testing all possible weight matrices. The system strategically selects candidate weight matrices for testing based on preliminary criteria, achieving sufficient selection accuracy without the excessive computational cost of evaluating every possible weight matrix combination
