WebFirst of all, I realized if I need to perform binary predictions, I have to create at least two classes through performing a one-hot-encoding. Is this correct? However, is binary cross-entropy only for predictions with only one class? If I were to use a categorical cross-entropy loss, which is typically found in most libraries (like TensorFlow ...

WebOne hot encoding with k-1 binary variables should be used in linear regression, to keep the correct number of degrees of freedom (k-1). The linear regression has access to all of the features as it is being trained, and therefore examines altogether the whole set of dummy variables. This means that k-1 binary variables give the whole ...

When using binary, a decoder is needed to determine the state. A one-hot state machine, however, does not need a decoder as the state machine is in the nth state if, and only if, the nth bit is high. A ring counter with 15 sequentially ordered states is an example of a state machine.
