How to perform one hot encoding on multiple categorical columns

WebOne-Hot Encoding is a general method that can vectorize any categorical features. 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. One-hot encoding is often used for indicating the state of a state machine. 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. A 'one-hot' implementation would have 15 flip flops chained in series with the Q output of each flip flop conn… breadcrumbs wireless
