Webb24 maj 2024 · To implement the grid search, we used the scikit-learn library and the GridSearchCV class. Our goal was to train a computer vision model that can automatically recognize the texture of an object in an image (brick, marble, or sand). The training pipeline itself included: Looping over all images in our dataset.
Webb12 juli 2016 · There are several ways of parallelizing algorithms in machine learning. Some algorithms can be made to be data-parallel (either across features or across samples). In this post we’ll look instead at model-parallelism (use same data across different models), and dive into a daskified implementation of GridSearchCV. What is grid search?
