Torch Machine Learning Platform

Context:
- It can contain a Torch torch Library.
- It can contain a Torch nn Library.
- It can be enhanced with an Extension Library, such as fblualib [1].
Example(s):
- Torch7 [2].
- Torch5 2008 [3]. "... Torch5 provides a Matlab-like environment for state-of-the-art machine learning algorithms. It is easy to use and provides a very efficient implementation, thanks to an easy and fast scripting language (Lua) and a underlying C implementation. Torch5 is the official successor of Torch3, and is now developed at NEC Laboratories America and Google Labs. ... "
- Torch4 [4].
- Torch3 2004 [5].
- ...
Counter-Example(s):
- TensorFlow Framework.
- Caffe Framework.
- Theano Python Library.
- Scikit-Learn.
- Deeplearning4j, an open source deep learning library written for Java and Scala.
- OpenNN, an open source neural networks library written in C++ for deep learning.
- Spark MLlib.

- QUOTE: For nearly four years, the open source Torch7 machine learning library has served as our primary research platform, combining excellent flexibility with very fast runtime execution, enabling rapid prototyping. ... Torch7 is currently being used by Facebook, Twitter, and many start-ups and academic labs as well as DeepMind, and I’m proud of the significant contribution it has made to a large community in both research and industry.

- The core package of Torch is torch. It provides a flexible N-dimensional array or Tensor, which supports basic routines for indexing, slicing, transposing, type-casting, resizing, sharing storage and cloning. This object is used by most other packages and thus forms the core object of the library. The Tensor also supports mathematical operations like max, min, sum, statistical distributions like uniform, normal and multinomial, and BLAS operations like dot product, matrix-vector multiplication, matrix-matrix multiplication, matrix-vector product and matrix product.
  The following exemplifies using torch via its REPL interpreter: ...

- Torch is the main package in Torch7 where data structures for multi-dimensional tensors and mathematical operations over these are defined. Additionally, it provides many utilities for accessing files, serializing objects of arbitrary types and other useful utilities.
- Tensor Library.
  - Tensor defines the all powerful tensor object that provides multi-dimensional numerical arrays with type templating.
  - Mathematical operations that are defined for the tensor object types.
