kandi X-RAY | xfeat Summary
Slides | Tutorial | Document | Installation. Flexible Feature Engineering & Exploration Library using GPUs and Optuna. xfeat provides sklearn-like transformation classes for feature engineering and exploration. Unlike sklearn API, xfeat provides a dataframe-in, dataframe-out interface. xfeat supports both pandas and cuDF dataframes. By using cuDF and CuPy, xfeat can generate features 10 ~ 30 times faster than a naive pandas operation.

QUESTION
I'm trying to write a python code for multivariate linear regression using mini-batch gradient descent. And there is an issue when running the predict function. xFeat
is a nd-array with shape n x d. beta
is an array of coefficients. yHat
is the predicted value.
ANSWER
Answered 2020-Oct-04 at 17:14Your beta list
is set to None in someplace. None always has no data and can not be subscriptable.
The error means that you attempted to index an object whose type is None. NoneType is the type of the None object - it represents a lack of value.
