Web9 jul. 2024 · We will use the MNIST dataset, which consists of grayscale images of handwritten digits (0–9) whose dimension is 28x28 pixels. Each pixel is 8 bits, so its value ranges from 0 to 255. Obtaining the dataset is very easy since there is a function for it built-in to Keras. Our output for our X and Y data is (60000, 28, 28) and (60000,1) respectively. WebYou can then run GridSearch as the following: grid_search = GridSearchCV (estimator=PIPELINE, param_grid=GRID, scoring=make_scorer (accuracy_score),# …
