module concrete.ml.sklearn.linear_model

Implement sklearn linear model.

class LinearRegression

A linear regression model with FHE.

Arguments:

• n_bits (int): default is 2.

• use_sum_workaround (bool): indicate if the sum workaround should be used or not. This

• feature is experimental and should be used carefully. Important note: it only works for a LinearRegression model with N features, N a power of 2, for now. More information available in the QuantizedReduceSum operator. Default to False.
