Introduction Understanding BM-25: A Powerful Algorithm for Information Retrieval Bm25 is an enhancement of the TF-IDF model that incorporates term frequency saturation and document length normalization to improve retrieval performance. When it comes to search engines and information retrieval, a vital piece of the puzzle is ranking the relevance of documents to a given query. One of the most widely used algorithms to achieve this is the BM25, Best Matching 25. BM25 is a probabilistic retrieval function that evaluates the relevance of a document to a search query, balancing simplicity and effectiveness, making it a popular choice in modern search engines and applications. ...

Introduction TF-IDF (Term Frequency-Inverse Document Frequency) is a statistical measure used to evaluate the importance of a word in a document relative to a collection of documents (corpus). It combines two metrics: Term Frequency (TF) and Inverse Document Frequency (IDF). The TF-IDF value increases proportionally with the number of times a word appears in the document and is offset by the frequency of the word in the corpus. Components of TF-IDF Term Frequency (TF): Measures how frequently a term appears in a document. It’s calculated as: ...

Tokenization is a fundamental yet often misunderstood process in the realm of large language models (LLMs). Despite its crucial role, it is a part of working with LLMs that many find daunting due to its complexity and the numerous challenges it introduces. In this blog post, we will explore the concept of tokenization, its importance in language models like GPT-2, and the various issues associated with it. Introduction to Tokenization Tokenization is the process of converting raw text into smaller units called tokens. These tokens can be as small as individual characters or as large as entire words or subwords, depending on the specific tokenizer being used. Tokenization is the first step in feeding text data into a neural network, making it a critical component in the performance of LLMs. ...

Introduction Hello everyone! By now, you’ve likely heard of ChatGPT, the revolutionary AI system that has taken the world and the AI community by storm. This remarkable technology allows you to interact with an AI through text-based tasks. The Technology Behind ChatGPT: Transformers The neural network that powers ChatGPT is based on the Transformer architecture, introduced in the 2017 paper “Attention is All You Need.” GPT stands for “Generatively Pre-trained Transformer.” The Transformer architecture is a landmark development in AI that revolutionized the field, primarily in natural language processing (NLP). The Transformer architecture, initially designed for machine translation, became the backbone for numerous AI applications, including ChatGPT. ...

Introduction This blog post dives into the fascinating world of computer vision, exploring how we can teach machines to “see” using convolutional neural networks (CNNs). This post is based on a lecture from MIT’s 6.S191: Introduction to Deep Learning course. What Does it Mean to “See”? Before diving into the technical details, let’s define “vision”. It’s not simply about identifying objects in an image. True vision goes beyond object recognition to understand the relationships between objects, their movements, and their future trajectories. Think about how you intuitively anticipate a pedestrian crossing the street or a car changing lanes. Building machines with this level of visual understanding is the ultimate goal. ...

Introduction In the world of software development, the ability to build and deploy applications across different architectures is invaluable. This capability becomes particularly essential when dealing with ARM-based applications such as those for embedded systems or newer ARM-based servers. In this blog post, we will explore how to build ARM64 Docker container images on an x86_64 machine using QEMU emulation and Docker’s buildx tool. Understanding the Challenge The main challenge in building Docker images for a different architecture than your host machine lies in the architecture-specific binaries and dependencies. Directly running ARM binaries on an x86_64 machine is not possible without emulation due to differences in architecture instruction sets. ...
