ML4ML: Automated Invariance Testing for Machine Learning Models
share
In machine learning workflows, determining invariance qualities of a model is a common testing procedure. In this paper, we propose an automatic testing framework that is applicable to a variety of invariance qualities. We draw an analogy between invariance testing and medical image analysis and propose to use variance matrices as “imagery” testing data. This enables us to employ machine learning techniques for analysing such “imagery” testing data automatically, hence facilitating ML4ML (machine learning for machine learning). We demonstrate the effectiveness and feasibility of the proposed framework by developing ML4ML models (assessors) for determining rotation-, brightness-, and size-variances of a collection of neural networks. Our testing results show that the trained ML4ML assessors can perform such analytical tasks with sufficient accuracy.
