The first expect your labels to be provided as integers, where the latter expects one-hot encodings. In the given example, they use the SparseCategoricalCrossentropy loss function, … WebCamel - > [0, 0, 0, 1] Why use a One Hot Encoding? One of the best advantages of One Hot encoding is that it represents categorical data to be more expressive. As we discussed earlier, many machine learning algorithms cannot be able to work with the categorical data directly, so that it needs to be converted into integer.

It is simple and fast to create and update the vectorization, just add a new entry in the vector with a one for each new category. However, that speed and simplicity also leads to the "curse of dimensionality" by creating a new dimension for each category.
