Notes on machine learning
Regression quattro stagioni
This post will explore the foundation of linear regression and implement four different methods of training a regression model on linear data: simple linear regression, ordinary least squares (OLS), gradient descent, and markov chain monte carlo (MCMC).
How to implement a RNN
Learn how to implement a recurrent neural network (RNN) in Python with the help of Numpy. The tutorial explains the basics of backpropagation-through-time and discusses some of the difficulties of training recurrent networks.
How to implement a neural network
Learn the basics of neural networks and how to implement them from scratch in Python. The tutorial starts with explaining gradient descent on the most basic models and goes along to explain hidden layers with non-linearities, backpropagation, and momentum. The math is explained along the way together with Python code examples.
Multi-armed bandit implementation
Learn the basics of Bayesian multi-armed bandit models while implementing a simple example in Python.
Introduction to the logistic and softmax classification functions and how to use them with the cross-entropy loss function.
Multivariate normal distribution: a primer
Introduction to the multivariate normal distribution that will show you how to represent, visualize, sample, and compute conditionals from this distribution.
TensorFlow Estimator & Dataset APIs
How to use TensorFlow's Estimator and Dataset APIs to train models.
