how the naive Bayes classifiers work, why it makes sense to define them the way they are and how to implement them in Python using NumPy. You can find the code onmy Github. It might help a bit to check out my primer on Bayesian statisticsA gentle Introduction to Bayesian Inferenceto get...
In this post, we are going to implement theNaive Bayes classifierin Python using my favorite machine learning library scikit-learn. Next, we are going to use the trained Naive Bayes (supervised classification), model to predict the Census Income. As we discussed the Bayes theorem innaive Bayes...

All the EEG signals in this data set were sampled at 100 Hz and were sliced into 30 s pieces. The codes were implemented with Python 3.6 and TensorFlow 1.13.1. First, we pre-trained the TinySleepNet classifier on the first twenty subjects using “twenty-fold” method. Specifically, we ...

It is often easy to come up with a list of rules to follow in order to solve a problem, but if the algorithm is too slow, it's back to the drawing board. Efficiency of an algorithm depends on its design and implementation. Since every procedure or formula for solving a problem based...
In general ML-II has a lesser accuracy then method involving MCMC, but is easier in implementation and use in practical examples, especially because of lesser computation performance demand [1]. 3.2. Approximation of Gaussian Process GP computation is problematic, because of the earlier mentioned ...
