Solution Overview

Problem

Conventional techniques for training models, such as SVM and DNN, face challenges in improving model accuracy due to inadequate dynamic adjustment of learning data based on hyperparameter values, leading to potential failures in accuracy enhancement.

Innovation Solution

A learning apparatus that divides learning data features into sets in chronological order, selects sets for training, and trains models using older data first, optimizing hyperparameters and training methods to enhance model accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If learning data is dynamically changed according to hyperparameter values, then the training process becomes more flexible, but model accuracy improvement cannot be ensured

Engineering Contradiction:
Improvedynamic adjustment of learning dataVSAvoidmodel accuracy
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent segments learning data into multiple time series data sets with different time spans (e.g., recent data, historical data). By dividing the learning data into chronological segments and selectively training on different segments based on hyperparameter values, the system achieves both adaptability in training dynamics and controlled accuracy improvement through systematic data selection.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If learning data is merely changed according to hyperparameter values, then the training process is simplified, but accuracy improvement fails when hyperparameter values are not appropriate

Engineering Contradiction:
Improvetraining process complexityVSAvoidmodel accuracy
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent implements dynamic selection of time series data sets based on hyperparameter values. The training process adaptively changes which time span of data is used (recent vs. historical) according to the hyperparameter settings, creating a dynamic training system that can respond to different configuration scenarios while maintaining accuracy through purposeful data selection.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If all learning data sets are used for training, then more features are learned, but training time increases and efficiency decreases

Engineering Contradiction:
Improvefeature learning completenessVSAvoidtraining efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent applies partial action by selectively training on specific time series data sets rather than using all available data. Based on hyperparameter values, the system trains on appropriate portions of the data (e.g., only recent data, or only historical data, or a combination), achieving sufficient feature learning without the computational overhead of processing the entire data set.

Inventive Principle:
Principle #16Partial or excessive action
