Last active September 9, 2018 20:52
Comparison of Character One-Hot Encoding with Embedding + Hashing encoding schemes
Character one-hot encoding Embedding or Bucketing
fixed length inputs variable and long inputs
low character cardinality chracter cardinality is not an issue
new values are frequent best to have visibility of entire population of inputs at design phase
