mir 0.17.0-alpha9

Mir

Generic Numerical Library for Science and Machine Learning.

Projects based on Mir

• Computer Vision Library for D Programming Language

Documentation

API can be found here. Read also the Mir blog.

Contents

• mir.ndslice Multidimensional Random Access Ranges and Arrays
• mir.sparse Sparse Tensors
• Sparse - DOK format
• Different ranges for COO format
• CompressedTensor - CSR/CSC formats
• mir.sparse.blas - Sparse BLAS for CompressedTensor
• mir.model.lda.hoffman - Online variational Bayes for latent Dirichlet allocation (Online VB LDA) for sparse documents. LDA is used for topic modeling.
• mir.combinatorics Combinations, combinations with repeats, cartesian power, permutations.
• mir.las.sum Functions and Output Ranges for Summation Algorithms. Works with user-defined types.
• Precise algorithm: improved analog of Python's fsum
• Pairwise algorithm: fast version for Input Ranges
• Kahan, KBN, and KB2 algorithms

In progress

• mir.random - non-uniform RNGs.
• mir.glas - Generic Linear Algebra Subroutines.

Compatibility

• LDC (LLVM D Compiler) >= 1.1.0-beta2 (recommended compiler).
• DMD (reference D compiler) >= 2.072.1.

Fast setup with the dub package manager

Dub is the D's package manager. You can create a new project with:

dub init <project-name>

Now you need to edit the dub.json add mir as dependency and set its targetType to executable.

{
	...
	"dependencies": {
		"mir": "~><current-version>"
	},
	"targetType": "executable",
	"dflags-ldc": ["-mcpu=native"]
}

Now you can create a main file in the source and run your code with

dub

Flags --build=release and --compiler=ldmd2 can be added for a performance boost:

dub --build=release --compiler=ldmd2

ldmd2 is a shell on top of LDC (LLVM D Compiler). "dflags-ldc": ["-mcpu=native"] allows LDC to optimize Mir for your CPU.

Contributing

See our TODO List. Mir is very young and we are open for contributing to source code, documentation, examples and benchmarks.

Notes

• mir.ndslice is a development version of the std.experimental.ndslice package.
