# Titan Robotics Team 2022: CUDA-based Regressions Module
# Written by Arthur Lu & Jacob Levine
# Notes:
# this should be imported as a python module using 'import regression'
# this should be imported as a python module using 'import cudaregress'
# this should be included in the local directory or environment variable
# this module is cuda-optimized and vectorized (except for one small part)
# setup:

1.0.0.002:
-Added more parameters to log, exponential, polynomial
-
-Added SigmoidalRegKernelArthur, because Arthur apparently needs
to train the scaling and shifting of sigmoids
1.0.0.001:
-initial release, with linear, log, exponential, polynomial, and sigmoid kernels
