i'm a newbie in programming. I try to use this library. it's very useful for me.
I want to show centroid in K-means clustering. how to show it? thank u so much..

Hi I would like to propose a better implementation for 'test_indices':

We can remove the unneeded np.array casting:

Cleaner/New:
test_indices = list(set(range(len(texts))) - set(train_indices))

Old:
test_indices = np.array(list(set(range(len(texts))) - set(train_indices)))

I tried some RNN regression learning based on the code in the "PyTorch-Tutorial/tutorial-contents/403_RNN_regressor.py" file, which did not work for me at all.

According to an accepted answer on stack-overflow (https://stackoverflow.com/questions/52857213/recurrent-network-rnn-wont-learn-a-very-simple-function-plots-shown-in-the-q?noredirect=1#comment92916825_52857213), it turns out that the li

This is a good first issue and will help new contributors to get familiar with the codebase. Also This issue doesn't aim to add all Metrics to mlpack since each metric would have to be maintained, this aims to add metrics that either I find essential (or have used a couple of time) or those metrics which are very common.
List of metrics that can be added include:

1. IoU and meanIoU

From the docs for https://simplestatistics.org/docs/#standardnormaltable:

The table used is the cumulative, and not cumulative from 0 to mean.

I'm having trouble understanding this sentence. What is meant by cumulative and not cumulative?

The help currently reads:
Vector S get; set;
Gets the singular values (Σ) of matrix in ascending value.

It should be:
descending order of magnitude.

2. 35 页， 正定矩阵的定义 （公式 2-15）
   标准正定矩阵的定义，应该没有 “对称矩阵” 这一条件吧？ 只是您在本书大多讨论的是“对称”正定矩阵，所以加上了 “对称” 这一条件？

From alan-turing-institute/MLJBase.jl#68:

This doesn't work:

@mlj_model mutable struct Bar
    a::Int = -1::(_ > -2)
end

But this does:

@mlj_model mutable struct Bar
    a::Int = (-)(1)::(_ > -2)
end

This needs to be documented in MLJ/docs/src/adding_models_for_general_use and MLJ/docs/src/quick_start_guide_to_adding_models

Hi @JavierAntoran @stratisMarkou,

First of all, thanks for making all of this code available - it's been great to look through!

Im currently spending some time trying to work through the Weight Uncertainty in Neural Networks in order to implement Bayes-by-Backprop. I was struggling to understand the difference between your implementation of `Bayes-by-Bac

I would be great if more examples of NeuralNetwork classes eg. MultiLayerPerceptron or using BackPropagation algo are created with examples.
May be Below link example can be implementated -
