Using Text Features to Predict the Great Stock Market Crash of 1929
Predicting financial crises is notoriously difficult. This is primarily a consequence of the infrequency of such events and the instability of relationships between financial variables. However, it is also related to the contagious nature of financial crises: if one bank expects another to liquidate its holdings... Read more
Why Learn Python for Data Processing
Python is one of the most popular languages in the world. It’s used in a lot of different fields, like web services, automation, data science, managing computer infrastructure, and artificial intelligence and machine learning. Its readable and concise syntax makes it a great option for teaching... Read more
How to Pivot and Plot Data With Pandas
A big challenge of working with data is manipulating its format for the analysis at hand. To make things a bit more difficult, the “proper format” can depend on what you are trying to analyze, meaning we have to know how to melt, pivot, and transpose... Read more
First Steps Before Applying Reinforcement Learning for Trading
There are many methodologies in algorithmic trading — from automated trade entry and close points based on technical and fundamental indicators to intelligent forecasts and decision making using complex maths and, of course, artificial intelligence. Reinforcement learning here stands out as a Holy Grail — no... Read more
Audio-Visual Speech Enhancement and Separation Based on Deep Learning
Imagine being at a cocktail party with your friends. Although you are surrounded by other people having their own conversations and a music band is playing in the background, you are still able to engage with your friends and understand what they are saying. The reason... Read more
Saying Hello to DataFrames.jl
A majority of data scientists use Python or R to perform data preparation tasks before jumping to modeling. The Julia language is a younger player in this field that promises that you will be able to do the number-crunching-intensive parts of your pipelines fast. However, the... Read more

You finally finished that college CS degree, completed hundreds of hours of training online, got your certifications, or simply have the skills you need to transition. The bottom line is, you are ready to start working in data science, an incredibly exciting field. And then, you... Read more
Promoting the Responsible Use of AI in Health Care
Artificial intelligence (AI) holds tremendous promise as a means of improving the efficiency and quality of health care delivery— from enhancing patient outreach and engagement, to managing medical and pharmacy inventory, to identifying patients at the greatest risk of disease progression. The tangible benefits of AI... Read more
Fast, Visual, and Explainable ML Modeling With PerceptiLabs
Pure-code ML frameworks like TensorFlow, have become popular for building ML models because they effectively offer a high-level grammar for describing model topologies and algorithms. This is a powerful approach, but it has limitations for providing insight and explainability of models. These issues are further magnified... Read more
Making Explainability Work in Practice
Complex ‘black box’ models are becoming more and more prevalent in industries involving high-stakes decisions (such as finance, healthcare, insurance). As machine learning algorithms take a prominent role in our daily lives, explaining their decision will only grow in importance via explainability. By now there is... Read more
