Expand description

Discretizes features using equal-frequency bins (quantiles)

§Arguments

  • array - The input array to discretize
  • n_bins - The number of bins to create
  • encode - The encoding method (‘onehot’ or ‘ordinal’)
  • axis - The axis along which to discretize (0 for columns, 1 for rows)

§Returns

  • Result<Array2<f64>> - The discretized array
