random forest tutorial Random Forests

Random Forests are one of the most powerful Machine Learning models, belonging to the category of Ensemble models. They are created by grouping together many individual Decision Trees, reducing the variance problems of these and increasing overall performance. You can learn about them, as always, with the following resources:

-Medium post Random Forest Explained: a graphical and intuitive explanation of what random forest are, how they are trained, the solutions they offer over traditional Decision Trees, and how they are used to make predictions.

-Statquest video on Random Forests.

Artificial Neural Networks

Artificial Neural networks are probably the most powerful Machine Learning tool out there. They can be used for all sorts of incredible tasks: from audio recognition on devices like Siri or Alexa, to driving autonomous Vehicles, to simply making predictions on numerical or categorical variables like a normal Machine Learning algorithm.

Brandon Roher’s Video Series

Despite of their power however, we must know when to use them and when they are not necessary or will not work out well. The following series of completely free videos by Brandon Roher is a great resource to start learning about them: End to End Machine Learning, Introduction to Neural Networks.

Deeplizard’s Youtube Channel and Website

A more introductory video-guide to Deep Learning can be found on deeplizard’s Youtube channel. It covers what neural networks are, how they are trained, and how they make predictions in very short, easy and concise videos.

They have all this same video content on their website along with other content like code and access to their patreon community.

MachineLearningMastery Introduction to Deep Learning

If you prefer some textual resource, Machine Learning Mastery’s introduction to Deep Learning is a very well written resource to learn what Deep Learning is, and why it has become so popular in the recent years.

A Hacker’s Guide to Neural Network – Andrew Karpathy’s Blog

The following blog, A Hacker’s Guide to Neural networks, by Andrew Karpathy, is a different resource that can be very useful to learn about Neural Networks.

It starts by abstracting them to the highest level, comparing them to circuits, then keeps on building on the theories, transforming this circuits into logistic regressions and support vector machines, that combined, end up making our final neural networks.

Processes like gradient descent and back propagation are also explained. You’ll like it every much if you have an electrical, or electronics engineering background.

Geoffrey Hinton’s Youtube Video Series

If what you are looking for is a complete, in depth tutorial of Neural Networks, one of the fathers of Deep Learning, Geoffrey Hinton, has series of 78 Youtube videos about this topic that come from a Coursera course with the University of Toronto, published on 2012(University of Toronto) on Coursera in 2012.

This series teaches the theory of everything and more of what you want to know about ANNs: from an introduction to parameter optimisation, RMSProp, Batch, and Stochastic gradient descent, Hopfield nets and a lot more. It is a fantastic resource that we are very happy to have found.

Lastly, if you are looking for something more engaging, and to deepen your knowledge and obtain an oficial certificate, take a look at our review of the Deep Learning Specialisation, by Stanford University and Andrew Ng.

Sentiment Analysis

Sentiment analysis or sentiment inference is a part of Natural Language Processing that has the goal of extracting a sentiment (usually positive, negative or neutral) from a certain sentence. This is not a straight-forward task, and it is a field that can provide a lot valuable business information: we can analyse sentiment on product reviews, on social networks, comments on web pages, and a lot more.


MonkeyLearn is a great resource for learning about Sentiment Analysis, how it is done, its use cases, and its application. Check them out!

Targeted Sentiment Analysis

What can we do when we don’t want to analyse the sentiment of a whole sentence, but rather the sentiment of a sentence towards an specific sentence within it? At howtolearnmaching learning we know that this is sometime the goal, and not just traditional sentiment analysis.

Here are some resources to know more about Targeted Sentiment Analysis:

Medium Post about Targeted Sentiment Analysis.

Interpretable Machine Learning

For most, Machine Learning is an almost magic field, where we give a computer some data, it does it’s thing, and outputs some information. This, however, is not true.

Machine Learning engineers and practitioners generally understand how a model works (i.e the process about how it learns and then makes predictions) however, when dealing with non-technical counterparts, it is very important to be able to explain why the model is doing what is doing.

This is the reason why Interpretable Machine Learning, or explainable AI has become a very hot field in the recent years: how to make black box machine learning models interpretable.

Christoph Molnar´s book and blog

For this, the best resource we have found is Christoph Molnar´s book, which you can find for free on a browser-friendly format here: Interpretable Machine Learning. Take a good look!
