A new theory on intelligence and how the neocortex works.

Introduction

For a long time, I have been following Numenta, a startup of neuroscientists whose goal is to understand the neocortex to reproduce the mechanisms in learning algorithms.

The founder, Jeff Hawkins, wrote the book A Thousand Brains: A New Theory of Intelligence. Attractive title for me who loves neuroscience and…

A theoretical way through n-grams, tf-idf, one-hot encoding, word embeddings. And a surprise with pre-trained models.

Natural Language Processing seeks to map language to representations that capture morphological, lexical, syntactic, semantic, or discourse characteristics that can be processed by machine learning methods.

It is necessary to present elements of theory before entering the algorithmic methodology. …

Take by the author — Deep Learning with Python, 2017, François Chollet book and my cat

A great tour in the world of Deep Learning in less than 10 minutes.

It took me a long time to open this book. More for fear of finding that I knew nothing more than for fear of being frustrated with knowing everything. I regularly receive newsletters on "best of" or "most read" books about artificial intelligence, machine learning, or deep learning. Deep Learning…

An application of the RNN family

For a long time, I heard that the problem of time series could only be approached by statistical methods (AR[1], AM[2], ARMA[3], ARIMA[4]). These techniques are generally used by mathematicians who try to improve them continuously to constrain stationary and non-stationary time series.

A friend of mine (mathematician, professor of…

In the world of machine learning and Kaggle competitions, the XGBoost algorithm has the first place.

Like many data scientists, XGBoost is now part of my toolkit. This algorithm is among the most popular in the world of data science (real-world or competition). Its multitasking aspect allows it to be used in regression or classification projects. It can be used on tabular, structured, and unstructured data.
