Intern Insights: Vaishnavi Ranganathan with Angela Busheska

ANGELA BUSHESKA: Yeah, absolutely. Thank you so much for having me. Super excited to be here and super excited to have spent three months—time flies!— as a researcher along with the project. So my name is Angela. I am originally from North Macedonia, a very small country next to Greece in the Balkans. And I spent my first, like, 16 years thinking that I would become a mathematician, really focused on math Olympiads. And then I moved to the capital […]

5 Free Books on Computer Vision

Image by Author | Ideogram5 Free Books on Computer Vision Computer vision is a branch of Artificial Intelligence (AI) that studies how machines can interpret and understand visual information, such as images and videos. Most computer vision models today are based on deep learning architectures like Convolutional Neural Networks (CNNs), which excel at tasks such as image classification, object detection, and segmentation. However, the necessary fundamentals to deeply understand the field date back to earlier times. To help you master […]

Understanding RAG III: Fusion Retrieval and Reranking

Understanding RAG III: Fusion Retrieval and RerankingImage by Editor | Midjourney & Canva Check out the previous articles in this series: Having previously introduced what is RAG, why it matters in the context of Large Language Models (LLMs), and what does a classic retriever-generator system for RAG look like, the third post in the “Understanding RAG” series examines an upgraded approach to building RAG systems: fusion retrieval. Before deep diving, it is worth briefly revisiting the basic RAG scheme we […]

Python Thread Safety: Using a Lock and Other Techniques

Python threading allows you to run parts of your code concurrently, making the code more efficient. However, when you introduce threading to your code without knowing about thread safety, you may run into issues such as race conditions. You solve these with tools like locks, semaphores, events, conditions, and barriers. By the end of this tutorial, you’ll be able to identify safety issues and prevent them by using the synchronization primitives in Python’s threading module to make your code thread-safe. […]

Understanding Python’s Global Interpreter Lock (GIL)

The Python Global Interpreter Lock or GIL, in simple words, is a mutex (or a lock) that allows only one thread to hold the control of the Python interpreter. This means that only one thread can be in a state of execution at any point in time. The impact of the GIL isn’t visible to developers who execute single-threaded programs, but it can be a performance bottleneck in CPU-bound and multi-threaded code. Since the GIL allows only one thread to […]
