Low-Rank Factorization

The key idea behind low-rank factorization is to replace high-dimensional tensors with lower-dimensional tensors. One type of low-rank factorization is compact convolutional filters, where the over-parameterized (having too many parameters) convolution filters are replaced with compactblocks to both reduce the number of parameters and increase speed.

Perturbation Test for a Regression Model

A perturbation test is a method used to evaluate a model’s robustness and stability. In machine learning, this test helps determine how sensitive the model’s predictions are to small changes (perturbations) in the input data. If a model is stable, small changes in the input should lead to minimal changes in the output. This method…

Calibration Curve for Classification Models

Calibration curves are specifically used for classification models. The primary goal of a calibration curve is to evaluate the reliability of the predicted probabilities in a classification task. A calibration curve checks how well predicted probabilities align with the actual observed frequencies (e.g., when a model predicts 70% probability of being positive, we expect about…
