Overview

[Due to the time taken @ uni, work + hell breaking loose in my life, since things have calmed down a bit, will continue commiting!!!] [By the way, I'm still looking for new contributors! Please help make HyperLearn no1!!]

drawing

HyperLearn is what drives Umbra's AI engines. It is open source to everyone, everywhere, and we hope humanity can rise to the stars.

[Notice - I will be updating the package monthly or bi-weekly due to other commitments]

Faster, Leaner GPU Sklearn, Statsmodels written in PyTorch

GitHub issues Github All Releases

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_) Ongoing documentation: https://hyperlearn.readthedocs.io/en/latest/index.html

I'm also writing a mini book! A sneak peak: drawing

Comparison of Speed / Memory

Algorithm n p Time(s) RAM(mb) Notes
Sklearn Hyperlearn Sklearn Hyperlearn
QDA (Quad Dis A) 1000000 100 54.2 22.25 2,700 1,200 Now parallelized
LinearRegression 1000000 100 5.81 0.381 700 10 Guaranteed stable & fast

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

I've also added some preliminary results for N = 5000, P = 6000 drawing

Since timings are not good, I have submitted 2 bug reports to Scipy + PyTorch:

  1. EIGH very very slow --> suggesting an easy fix #9212 https://github.com/scipy/scipy/issues/9212
  2. SVD very very slow and GELS gives nans, -inf #11174 https://github.com/pytorch/pytorch/issues/11174

Help is really needed! Message me!


Key Methodologies and Aims

1. Embarrassingly Parallel For Loops

2. 50%+ Faster, 50%+ Leaner

3. Why is Statsmodels sometimes unbearably slow?

4. Deep Learning Drop In Modules with PyTorch

5. 20%+ Less Code, Cleaner Clearer Code

6. Accessing Old and Exciting New Algorithms


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 necessary 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

Goals & Development Schedule

Will Focus on & why:

1. Singular Value Decomposition & QR Decomposition

* SVD/QR is the backbone for many algorithms including:
    * Linear & Ridge Regression (Regression)
    * Statistical Inference for Regression methods (Inference)
    * Principal Component Analysis (Dimensionality Reduction)
    * Linear & Quadratic Discriminant Analysis (Classification & Dimensionality Reduction)
    * Pseudoinverse, Truncated SVD (Linear Algebra)
    * Latent Semantic Indexing LSI (NLP)
    * (new methods) Correlation Regression, FGLS, Outlier Tolerant Regression, Generalized MICE, Splines (Regression)
