Two-player games can be solved by following a very intuitive algorithm called Regret Matching 1. Players modify their action probabilities according to the so-called regrets or advantages, which can be thought as consequences of alternative choices. For a good overview of the topic, see the friendly yet detailed introduction by Neller and Lanctot 2. The …

This post explains how to measure GPU utilisation in real-time using tools provided by NVIDIA.
Staring from the version 2.x PyTorch, a popular deep-learning framework, introduces a JIT compiler torch.compile. In this post, I am sharing a non-trivial example demonstrating how this tool can reduce memory footprint on GPU. The point of departure is a sub-routine which computes similarity, similar to covariance but not as friendly to compute. For two …

Location on maps are often provided in a Coordinate Reference System (CRS). In computer vision projects, however, we need to translate them to pixels. Plotting and transformations can be accomplished with the rasterio Python module. Below I share a useful snippet showing how to convert CRS locations to pixel coordinates:
Visualizing code as a syntax tree is both funny and useful, as seen from impressive applications such as creating lineage of SQL which helps to understand complex queries in business. Abstract syntax trees are not only widely used in industry but are still a subject of top academic research1,2. This post demonstrates how to work …
How to prototype with multiple ML libraries in Cloud? Best to build on top of a rich pre-configured environment such as Kaggle image, extending it with a local virtual environment.
How to run pre-commit checks on CI/CD effectively?
As anticipated by many, Twitter stopped offering its (limited!) API for free 1. Now, what options do you have to programmatically access the public content for free?In this context, it is worth mentioning the library snscrape, a tool (well-maintained as of now) for extracting the content from social media services such as Facebook, Instagram or …
Azure Cloud is a popular work environment for many data scientists, yet many features remain poorly documented. This note shows how to monitor Azure experiments in a more handy and detailed way than through web or cl interface. The trick is to create a dashborad of experiments and their respective runs, up to a desired …
Poetry, a popular Python package manager, prefers to use keyring to manage passwords for private code repositories. Storing passwords in plain text is a secondary option, but may be needed in case of either issues in poetry itself or with keyring configuration (may not be properly installed, be locked etc). To disable the use of …
