Tests should keep apps from being flaky. But tests themselves can become flaky—even the most straightforward ones. Here's how we dove into a problematic test on a PostgreSQL-backed Rails app, and what we uncovered.
Supervised learning is the key to computer vision and deep learning. However, what happens when you don’t have access to large, human-labeled datasets?
In this article, Toptal Computer Vision Developer Urwa Muaz demonstrates the potential of semi-supervised image classification using unlabeled datasets.
Markov Chain Monte Carlo (MCMC) methods let us compute samples from a distribution even though we can’t do this relying on traditional methods.
In this article, Toptal Data Scientist Divyanshu Kalra will introduce you to Bayesian methods and Metropolis-Hastings, demonstrating their potential in the field of probabilistic programming.
