Variable Mix Ratio Data Generation for GAN Convergence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generative Adversarial Networks (GANs) face inefficiencies in learning, requiring extensive time for the Generator and Discriminator to converge effectively.
Innovation Solution
A data generation apparatus and method that incorporates a mix data generation unit to mix real and fake data at a variable mix ratio based on data element position or time, allowing the Discriminator to learn from a mix of real, fake, and mix data, thereby optimizing the learning process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the Generative Adversarial Network is used to generate fake data and train the Discriminator, then the model can learn to discriminate real from fake data, but the learning process requires enormously much time and is difficult to perform efficiently
Solution Approach 1:
The patent applies preliminary action by pre-processing the training data through mixing real and fake data at different ratios before feeding it to the Discriminator. The mix data generation unit creates augmented training samples in advance, allowing the Discriminator to learn from diverse data distributions without requiring extensive training time. This pre-prepared mixed data serves as enhanced training material that accelerates the learning process while maintaining high discrimination accuracy.
2Productivity
If the mix ratio is kept constant for all data elements, then the data processing is simple, but the learning efficiency is reduced
Solution Approach 1:
The patent implements local quality by varying the mix ratio according to the position of each data element within the data sequence. Instead of applying a uniform mix ratio to all data elements, the system adjusts the mix ratio locally based on positional information, allowing different regions of the training data to have optimized mixing characteristics. This position-dependent mix ratio strategy enhances learning efficiency by providing spatially varied training examples while maintaining manageable processing complexity through a systematic approach.

AI summary
A data generation apparatus (2) has: an obtaining unit (21) that obtains real data (D_real); a fake data generating unit (22) that generates fake data (D_fake) that imitates the real data; and a mix data generating unit (23) that generates mix data (D_mix) by mixing the real data and the fake data at a desired mix ratio (a), the mix data generating unit changes the mix ratio that is used to generate a data element of the mix data based on a position of the data element in the mix data.
