Introduction to Bayes
Published:
In very few words, Bayes is a framework for reasoning about uncertainty using probability. The core idea is that we update our beliefs about an hypothesis as we gather more and more data (evidence) .

Built-in Sequences in Python
Python provides several built-in sequence types that are implemented in C, which are divided into two categories based on how they store their contents: Container sequences and Flat sequences.
Dunder Methods
Published:
What are special methods?
They are ‘predefined’ methods that allow you to customize the behavior of classes. Can also be referred to as “dunder” (double-underscore) methods.

Cost Function
Published:
Definition
In machine learning (ML), a cost function (also called a loss function) is a measure of how well the model’s predictions match the actual outcomes or targets. The cost function gives a numerical value, the cost or loss that quantifies the error (or “cost”) between the predicted values and the true values The goal of training a machine learning model is to minimize this cost function by adjusting the model’s parameters.
Recurrent Neural Networks
Published:
In this post we will review the very basics of Recurrent Neural Networks. What are they, the math behind it and how they can be used.
Cross entropy
Published:
What is Cross-Entropy?
Cross-entropy is one of many possible cost function that we might consider choosing for our model and is typically used in Categorical Classification. This means, a model that aims to predict whether our input data is one in a finite size possible classes.

Introduction to Unittesting
Published:
Why use Unit Testing?
Unittesting for any serious project is mandatory, not optional. It’s a good negative indicator -i.e. it points out poor-quality code with relatively high accuracy-. If the code is hard to unit test, it’s a strong sing that the code needs improvement.

KNN-Graph

Let’s say we have a dataset of 10 molecules (A through J), and we want to construct a 3-NN graph (k=3) where k indicates the number of neighbours.

LSH Forest
Published:
Locality-sensitive hashing or LSH, allows us to focus on pairs that are likely to be similar, instead of having to look at all pairs possible. It reduces therefore the amount of computational time required by a brute force approach.
MinHashing
Published:
TL;DR: MinHashing is a way to reduce the dimensionality of fingerprints. Instead of comparing 512-bit vectors directly -these are the vectors that we obtain after the fingerprint is applied to a SMILES format molecule-, MinHash reduces these vectors to smaller hashes that preserve similarity between molecules.
