Too Long; Didn't Read
The ADA algorithm generates minibatches for nonlinear regression models by selecting samples, computing projections, and applying transformations based on predefined criteria. This process enhances data diversity with each minibatch, improving model robustness and performance.

3.3 Algorithm
Finally, in this section, we present the ADA algorithm step by step (Algorithm 1) to generate minibatches of data that can be used to train neural networks (or any other nonlinear regressor) by any stochastic gradient descent method. As discussed previously, we propose to repeat the augmentation with different parameter combinations for each minibatch.
