Faster, Leaner GPU Sklearn Statsmodels written in PyTorch

Faster, Leaner GPU Sklearn Statsmodels written in PyTorch

hyperlearn

50%+ Faster, 50%+ less RAM usage, GPU support re-written Sklearn, Statsmodels combo with new novel algorithms.

HyperLearn is written completely in PyTorch, NoGil Numba, Numpy, Pandas, Scipy & LAPACK, and mirrors (mostly) Scikit Learn. HyperLearn also has statistical inference measures embedded, and can be called just like Scikit Learn's syntax (model.confidence_interval_)

Time(s) is Fit + Predict. RAM(mb) = max( RAM(Fit), RAM(Predict) )

1. Embarrassingly Parallel For Loops

  • Including Memory Sharing, Memory Management
  • CUDA Parallelism through PyTorch & Numba

2. 50%+ Faster, 50%+ Leaner

3. Why is Statsmodels sometimes unbearably slow?

  • Confidence, Prediction Intervals, Hypothesis Tests & Goodness of Fit tests for linear models are optimized.
  • Using Einstein Notation & Hadamard Products where possible.
  • Computing only what is neccessary to compute (Diagonal of matrix and not entire matrix).
  • Fixing the flaws of Statsmodels on notation, speed, memory issues and storage of variables.

4. Deep Learning Drop In Modules with PyTorch

  • Using PyTorch to create Scikit-Learn like drop in replacements.

5. 20%+ Less Code, Cleaner Clearer Code

  • Using Decorators & Functions where possible.
  • Intuitive Middle Level Function names like (isTensor, isIterable).
  • Handles Parallelism easily through hyperlearn.multiprocessing

6. Accessing Old and Exciting New Algorithms

  • Matrix Completion algorithms - Non Negative Least Squares, NNMF
  • Batch Similarity Latent Dirichelt Allocation (BS-LDA)
  • Correlation Regression
  • Feasible Generalized Least Squares FGLS
  • Outlier Tolerant Regression
  • Multidimensional Spline Regression
  • Generalized MICE (any model drop in replacement)
  • Using Uber's Pyro for Bayesian Deep Learning
