Web07. jun 2024. · The tf.one_hot Operation. You’ll notice a few key differences though between OneHotEncoder and tf.one_hot in the example above.. First, tf.one_hot is simply an operation, so we’ll need to create a Neural Network layer that uses this operation in order to include the One Hot Encoding logic with the actual model prediction logic. Second, … Web30. jun 2024. · One-Hot Encoding For categorical variables where no such ordinal relationship exists, the integer encoding is not enough. In fact, using this encoding and allowing the model to assume a natural ordering between categories may result in poor performance or unexpected results (predictions halfway between categories).
