Solution Overview

Problem

In machine learning modeling, samples obtained through manual annotation and user behavior extraction often contain noise due to misoperation and cheating, which significantly impacts the training of recommendation models.

Innovation Solution

A method is provided for training a model in an information recommendation system, where a reference training sample is purified and denoised using a sample model, and an updated target model is obtained by inputting the purified sample into a target model, enabling the system to replace manual rules with a machine learning scheme and improve the model's accuracy, generalization, and transfer ability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If samples are obtained from manual annotation and user behavior extraction, then the model training process can be completed, but the samples contain a lot of noise which significantly impacts the model training effect

Engineering Contradiction:
Improvemodel training efficiencyVSAvoidmodel training quality
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent introduces a sample selection model as an intermediary between the noisy sample data and the target model training process. This intermediary model filters and selects high-quality samples, thereby resolving the contradiction between maintaining training efficiency and improving training quality by eliminating noise without requiring manual review of all samples

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements self-service by automatically identifying and filtering noisy samples through the sample selection model without requiring manual annotation or review. The model autonomously processes the sample data, selects appropriate samples, and feeds them to the target model for training, thereby maintaining productivity while improving reliability

Inventive Principle:
Principle #25Self-service

2Reliability

If manual annotation is used to obtain samples, then sample quality can be controlled, but the process is time-consuming and labor-intensive

Engineering Contradiction:
Improvesample qualityVSAvoidsample preparation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system replaces manual annotation with automated self-service through the sample selection model, which independently evaluates and selects samples based on learned patterns from historical data, thereby eliminating time-consuming manual review while maintaining sample quality

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The sample selection model learns from historically verified high-quality samples and creates a selection criteria copy, using this learned pattern to automatically identify similar high-quality samples in the future without requiring repeated manual verification, thus reducing time loss while maintaining quality

Inventive Principle:
Principle #26Copying
