Compute statistics along dimensions

5

It is useful to compute certain statistics along specific dimensions. I open this thread to derive the development along this line. - [ ] `skewness` - [ ] `kurtosis` -...

Contour plot

It is useful to have a contour plotting function, one that similar to MATLAB's.

Performance of samplers

11

Thanks to @simonbyrnes' recent efforts, we already have some in-house samplers. I just run a systematic benchmarking of samplers implemented in this package (using [BenchmarkLite.jl](https://github.com/lindahua/BenchmarkLite.jl)): Here are the results. They...

- architecture of the overall framework - how to create new expressions - kernel-based evaluation - create new random distributions

- common facilities - matrix concepts and classes - simd and math - matrix expressions - kernel-based evaluation - linear algebra - random number generation

Devices to inspect the structure of an expression The implementation should be non-instrusive, relying on external template class with specializations. ``` C++ // some declarations template class matexpr_typeinfo; template matexpr_typeinfo...

- fill - row-wise / column-wise fill

- L2 blocking

implement and add this function to math_base.h It is useful for various machine learning models, notably Latent Dirichlet Allocation.
