Binary encoding vs one hot encoding
WebMay 21, 2024 · 3 Answers Sorted by: 32 Imagine your have five different classes e.g. ['cat', 'dog', 'fish', 'bird', 'ant']. If you would use one-hot-encoding you would represent the presence of 'dog' in a five-dimensional binary vector like [0,1,0,0,0]. WebDec 14, 2015 · 2. "When using XGBoost we need to convert categorical variables into numeric." Not always, no. If booster=='gbtree' (the default), then XGBoost can handle categorical variables encoded as numeric directly, without needing dummifying/one-hotting. Whereas if the label is a string (not an integer) then yes we need to comvert it.

WebMar 6, 2024 · The preferred encoding depends on the nature of the design. Binary encoding minimizes the length of the state vector, which is good for CPLD designs. One-hot encoding is usually faster and uses more registers and less logic. That makes one-hot encoding more suitable for FPGA designs where registers are usually abundant.
