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

Some key current achievements of HyperLearn:

• 70% less time to fit Least Squares / Linear Regression than sklearn + 50% less memory usage
• 50% less time to fit Non Negative Matrix Factorization than sklearn due to new parallelized algo
• 40% faster full Euclidean / Cosine distance algorithms
• 50% less time LSMR iterative least squares
• New Reconstruction SVD - use SVD to impute missing data! Has .fit AND .transform. Approx 30% better than mean imputation
• 50% faster Sparse Matrix operations - parallelized
• RandomizedSVD is now 20 - 30% faster

Around mid 2022, Hyperlearn will evolve to GreenAI and aims to incorporate:

• New Paratrooper optimizer - fastest SGD variant combining Lookahead, Learning Rate Range Finder, and more!
• 30% faster Matrix Multiplication on CPUs
• Software Support for brain floating point (bfloat16) on nearly all hardware
• Easy compilation on old and new CPU hardware (x86, ARM)
• 100x faster regular expressions
• 50% faster and 50% less memory usage for assembly kernel accelerated methods
• Fast and parallelized New York Times scraper
• Fast and parallelized NYSE Announcements scraper
• Fast and parallelized FRED scraper
• Fast and parallelized Yahoo Finance scraper

I also published a mini 50 page book titled "Modern Big Data Algorithm".

Comparison of Speed / Memory

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

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

Help is really needed! Message me!

1. Embarrassingly Parallel For Loops

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

<a id='2'></a>

2. 50%+ Faster, 50%+ Leaner

• Matrix Multiplication Ordering: https://en.wikipedia.org/wiki/Matrix_chain_multiplication
• Element Wise Matrix Multiplication reducing complexity to O(n^2) from O(n^3): https://en.wikipedia.org/wiki/Hadamard_product_(matrices)
• Reducing Matrix Operations to Einstein Notation: https://en.wikipedia.org/wiki/Einstein_notation
• Evaluating one-time Matrix Operations in succession to reduce RAM overhead.
• If p>>n, maybe decomposing X.T is better than X.
• Applying QR Decomposition then SVD might be faster in some cases.
• Utilise the structure of the matrix to compute faster inverse (eg triangular matrices, Hermitian matrices).
• Computing SVD(X) then getting pinv(X) is sometimes faster than pure pinv(X)

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

Goals & Development Schedule

Hyperlearn will be revamped in the following months to become Moonshot GreenAI with over an extra 150 optimized algorithms! Stay tuned!! Also you made it this far!
