WebRTC Fundamentals

WebRTC (Web Real-Time Communication) is an open-source project that enables real-time communication between browsers and devices using peer-to-peer connections. It allows audio, video, and data sharing without requiring additional plugins or external software. How Does WebRTC Work? WebRTC works by establishing a direct connection between two peers (browsers or applications) to transmit media (audio/video) and data. The connection process involves several steps: Media Capture – A user’s camera and microphone are accessed. Signaling – Exchanging connection details between peers via a signaling server (e.g., using WebSockets). ICE Candidate Discovery – Finding the best network path between peers. Connection Establishment – Securely connecting the peers. Data Transmission – Streaming audio/video or sending arbitrary data. 2. Main Components of WebRTC WebRTC consists of three primary components: ...

Supervised Fine-Tuning (SFT)

What is Supervised Fine-Tuning (SFT)? Supervised fine-tuning is a training strategy where a pre-trained language model is further refined on a carefully curated dataset of prompt-response pairs. The primary goal is to “teach” the model how to generate appropriate, contextually relevant, and human-aligned responses. Key points about SFT include: Data Curation: The model is exposed to a dataset that contains high-quality examples—often created by human annotators—that demonstrate the desired behavior (e.g., step-by-step reasoning, correct coding outputs, or helpful dialogue responses). Instruction Following: By training on these examples, the model learns to interpret prompts as instructions and produce answers that mimic the reasoning and style of the training data. Limitations: While SFT works well to instill basic response quality, it is typically limited by the dataset’s scope and may not encourage the model to “think” beyond what is explicitly provided. Furthermore, excessive fine-tuning can lead to overfitting and reduce the model’s ability to generalize to unseen tasks. For many contemporary language models, SFT is the standard method used to bridge the gap between raw pre-training and interactive, user-facing performance. ...

TF-IDF

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: ...

Understanding Tokenization in Large Language Models: A Deep Dive – Part 1

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. ...
