Transformer vs RNN Performance for Sequence Modelling

by

The rise of transformers has fundamentally reshaped how we approach sequence modeling in deep learning. For years, recurrent neural networks—LSTMs and GRUs—dominated tasks involving sequential data like language translation, time series prediction, and speech recognition. Then in 2017, the “Attention is All You Need” paper introduced transformers, claiming better performance with greater parallelization. Today, transformers … Read more

Speculative Decoding for Faster LLM Token Generation

by

Large language models generate text one token at a time in an autoregressive fashion—each token depends on all previous tokens, creating a sequential bottleneck that prevents parallelization. This sequential nature is fundamental to how transformers work, yet it creates a frustrating limitation: no matter how powerful your GPU is, you’re stuck generating tokens one at … Read more

LLM Benchmarking Using HumanEval, MMLU, TruthfulQA, and BIG-Bench

by

As large language models proliferate across research labs and production systems, rigorous evaluation has become essential for comparing capabilities, tracking progress, and identifying limitations. LLM benchmarking using HumanEval, MMLU, TruthfulQA, and BIG-Bench represents the gold standard approach to comprehensive model assessment, with each benchmark testing distinct critical capabilities. These four benchmarks have emerged as the … Read more

What is Fine-Tuning in Large Language Models

by

Large language models like GPT-4, Llama, and Claude have transformed how we interact with AI, but their true power emerges through a process called fine-tuning. Understanding what fine-tuning is in large language models can unlock capabilities that general-purpose models simply can’t deliver, enabling specialized applications across industries from healthcare to finance to customer service. This … Read more

Deploying Debezium on AWS ECS or Fargate

by

Debezium’s change data capture capabilities transform databases into event streams, enabling real-time data pipelines, microservices synchronization, and event-driven architectures. While Kafka Connect provides the standard deployment model for Debezium connectors, running this infrastructure on AWS demands careful consideration of container orchestration options. ECS (Elastic Container Service) and Fargate offer distinct approaches to deploying Debezium—ECS provides … Read more

Differences Between K-Means, K-Medoids, and K-Modes

by

Clustering algorithms form the backbone of unsupervised machine learning, organizing data into meaningful groups without predefined labels. Among the most widely used partitioning methods, k-means, k-medoids, and k-modes appear deceptively similar—all partition data into k clusters and iteratively optimize cluster assignments. However, fundamental differences in how they represent clusters, measure distances, and handle different data … Read more

Implementing RAG Locally: End-to-End Tutorial

by

Building a production-ready RAG system locally from scratch transforms abstract concepts into working software that delivers real value. This tutorial walks through the complete implementation process—from installing dependencies through building a functional system that can answer questions about your documents. Rather than relying on high-level abstractions that hide complexity, we’ll build each component deliberately, understanding … Read more

The Difference Between GPT-4o and Open Source LLMs

by

The artificial intelligence landscape has evolved dramatically, with large language models (LLMs) becoming essential tools for businesses and developers. At the center of this evolution stands a fundamental choice: proprietary models like GPT-4o from OpenAI versus open source alternatives such as Llama, Mistral, and Qwen. Understanding the difference between GPT-4o and open source LLMs isn’t … Read more

RAG for Beginners: Local AI Knowledge Systems

by

Retrieval-Augmented Generation transforms language models from impressive conversationalists with limited knowledge into powerful systems that can answer questions about your specific documents, databases, and proprietary information. While LLMs trained on internet data know general facts, they can’t tell you what’s in your company’s internal documentation, your personal research notes, or yesterday’s meeting transcripts. RAG solves … Read more

How to Fine-Tune a Local LLM for Custom Tasks

by

Fine-tuning large language models transforms general-purpose AI into specialized tools that excel at your specific tasks, whether that’s customer service responses in your company’s voice, technical documentation generation following your standards, or domain-specific question answering with proprietary knowledge. While cloud-based fine-tuning services exist, running the entire process locally provides complete data privacy, eliminates ongoing costs, … Read more
