Solution Overview
Problem
Current methods lack an effective way to measure the similarity between datasets, which is crucial for applications like transfer learning and data augmentation in AI, where dataset similarity is essential but challenging to quantify consistently.
Innovation Solution
The method employs an autoencoder to encode and reconstruct latent space representations of reference and target datasets, allowing for the comparison of similarity by analyzing the generated outputs, which indicates the similarity between the target and reference datasets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to measure dataset similarity, then the process is simple, but the measurement precision and reliability are insufficient for AI applications
Solution Approach 1:
The patent introduces an autoencoder as an intermediary system between the reference dataset and target dataset. The autoencoder learns a latent space representation that serves as a mediator for comparing datasets. By encoding both datasets into the same latent space and measuring the distance between representations, the system achieves precise similarity measurement while managing complexity through the use of this intermediate representation layer.
Solution Approach 2:
The patent transforms datasets from their original high-dimensional form into latent space representations with different parameters. The autoencoder learns optimal encoding parameters that capture essential characteristics of the data. By changing the parameter space from raw data dimensions to latent space dimensions, the system enables meaningful similarity comparison while reducing the complexity of direct high-dimensional comparison.
2Adaptability or versatility
If no similarity measurement method is used, then the system is simple, but the adaptability for transfer learning and data augmentation is poor
Solution Approach 1:
The patent creates a universal similarity measurement system based on autoencoders that can be applied across multiple AI tasks including transfer learning, data augmentation, and dataset selection. The latent space representation serves as a universal framework that adapts to different reference and target datasets. This multi-functional approach enables the system to handle various AI applications while maintaining a consistent measurement methodology, thereby improving adaptability without proportionally increasing complexity.
3Productivity
If manual assessment of dataset similarity is used, then the process is simple to understand, but the productivity and consistency are low
Solution Approach 1:
The patent implements a self-service measurement system where the autoencoder automatically learns the appropriate similarity metrics and performs the comparison without manual intervention. The system trains the autoencoder on the reference dataset, then automatically encodes and compares target datasets, generating similarity scores autonomously. This automation dramatically improves productivity and consistency while the modular architecture keeps the implementation complexity manageable through standardized processes.

AI summary
A computer-implemented method comprises: inputting into an autoencoder sets of input samples, each of the sets of input samples comprising: a reference input sample of a reference dataset and one or more target input samples of one or more target datasets, the autoencoder being trained using the reference dataset. The autoencoder generates a respective set of outputs for each set of the input samples to thereby form one or more respective sets of outputs, each of the one or more sets of outputs comprising the reference output and the one or more target outputs for a respective set of input samples; and determining the similarity of each of the one or more target datasets to the reference dataset by comparing each of the one or more target outputs to respective target input samples of each of the sets of input samples.
