Three Machine Learning Practices That Keep Your Identity Safe
As privacy concerns escalate in the age of big data, developers constantly evolve artificial intelligence and machine learning techniques to protect individuals’ identities. Machine learning systems enable businesses to more effectively identify fraud and keep user information safe. These systems gather data that can provide much more powerful insights... Read more
An Introduction to Reinforcement Learning Concepts
Individuals interested in reinforcement learning crowded into a room at ODSC Europe 2018. There, Badoo’s lead data scientist Leonardo De Marchi hosted a four-hour workshop to guide attendees through the first steps. What is reinforcement learning? Reinforcement learning is one machine learning approach. Most people know of supervised and unsupervised learning.... Read more
Client-side Web Development and Machine Learning
You might not expect client-side web development and machine learning to be in the same sentence. In this article, however, we’re going to look at how and why these two are beginning to collaborate rather successfully. There are many hidden uses for a collaboration between Javascript and machine learning.... Read more
Crash Course: Pool-Based Sampling in Active Learning
Active learning is a class of machine learning problems where labeled data isn’t available for supervised algorithms. Let’s take the classic setup as an example. Say we have pictures of birds and want to classify them by type, but the images don’t have labels for what kind of bird... Read more
Classic Regularization Techniques in Neural Networks
Neural networks are notoriously tricky to optimize. There isn’t a way to compute a global optimum for weight parameters, so we’re left fishing around in the dark for acceptable solutions while trying to ensure we don’t overfit the data. This is a quick overview of the most popular approaches... Read more
How Entertainment and Social Media Giants are Using Machine Learning
Major names in social media didn’t get there by accident. In addition to their excellent products, marketing, and sales strategies, machine learning is a huge part of the backbone that makes many of their processes successful. Facebook, Twitter, among other names you’ve definitely heard of have become the powerhouses... Read more
Exploring Scikit-Learn Further: The Bells and Whistles of Preprocessing
In my previous post, we constructed a simple cross-validated regression model using Scikit-Learn in 35 lines. It’s pretty amazing that we can perform machine learning with so little effort, but we just did the bare minimum in order to get a working model. Frankly, it didn’t even perform that well....

Three Ways Researchers are Using Data Science for Good
Data experts have long identified marginalization and narrow-minded problem solving as some of the biggest challenges facing data science. When large technology enterprises only seek solutions to problems they face within their company and their communities, it exacerbates inequalities. But companies, nonprofits, and individuals across the globe are making... Read more
What Model Should I Choose for My Data Science Project?
What to ask yourself when you’re balancing model performance, interpretability, and other costs It might seem silly to bother doing anything other than build the best black box machine learning model possible, as long as it gets good performance. That makes perfect sense on personal projects and Kaggle competitions. But it’s an... Read more
K-Means Clustering Applied to GIS Data
GIS can be intimidating to data scientists who haven’t tried it before, especially when it comes to analytics. On its face, mapmaking seems like a huge undertaking. Plus esoteric lingo and strange datafile encodings can create a significant barrier to entry for newbies. There’s a reason why there are experts who... Read more
