Handling Imbalanced Classification: What Works Better Than SMOTE

Vipin Vashisth — Sun, 12 Jul 2026 09:57:19 +0000

Most real-world classification problems are imbalanced. Fraud, disease, churn, and defects are rare by nature. Standard classifiers chase accuracy, so they quietly ignore the very class you care about. For years, SMOTE was the reflex fix that everyone reached for first. But SMOTE often fails on the messy, high-dimensional data that production systems actually see. […]

RAG Evaluation Frameworks Compared: RAGAS vs TruLens vs DeepEval

Soumil Jain — Sat, 11 Jul 2026 18:16:00 +0000

LLMs are getting stronger every day, and building a RAG pipeline has never been easier. Knowing whether it actually works is not. Most teams ship a RAG system, see decent-looking answers, and call it done, until users hit hallucination, missing context, or irrelevant chunks. That’s where evaluation frameworks come in. RAGAS, TruLens, and DeepEval are […]

Loop Engineering for AI Agents: How /loop is Changing AI Workflows

Harsh Mishra — Thu, 09 Jul 2026 17:13:49 +0000

AI agents are moving from one-time assistants to persistent workers that can repeat tasks, monitor changes, run checks, update workflows, and return with results. Instead of prompting an LLM once and deciding every next step manually, teams can now use AI agents that keep working (on a Loop) until a goal or stop condition is […]

DeepSeek DSpark: The Speculative Decoding Trick Behind 400% Faster LLM

Riya Bansal — Wed, 08 Jul 2026 18:26:00 +0000

DeepSeek’s new DSpark module brings speculative decoding to DeepSeek-V4. It might look like a niche inference tweak, but in production it boosted per-user generation speed by 60 to 85 percent with no drop in model quality. What sets DSpark apart is that it tackles two longstanding problems at once, weak draft quality and the waste […]

OKF: Redefining Knowledge Bases for AI Agents

Shaik Hamzah — Tue, 07 Jul 2026 11:45:43 +0000

In June 2026, Google introduced the Open Knowledge Format (OKF), an open specification for how AI agents organise and exchange knowledge. An OKF bundle is just Markdown files, lightweight YAML metadata, and links between concepts, yet it challenges the assumption that every AI application needs embeddings and vector databases. Because the knowledge base is plain […]

Modern VLMs Explained: How GPT-4o, Gemini, Claude Vision, and Qwen-VL Work

Janvi Kumari — Mon, 06 Jul 2026 05:14:11 +0000

Vision Language Models, or VLMs, are AI models that can understand both visual content and language. While earlier models like CLIP and BLIP connected images with text, modern VLMs can analyze images, read documents, interpret charts, answer visual questions, and support multimodal conversations. Models like GPT-4o, Gemini, Claude Vision, and Qwen-VL are making visual AI […]

YOLO26 Tutorial: Object Detection, Pose Estimation & More

Mounish V — Sat, 04 Jul 2026 19:55:13 +0000

Looking to model to implement pose estimation? I know something that can perform detection, instance segmentation, pose estimation and classification, all of that in real-time. Yes, I’m talking about the YOLO26 from ultralytics. It can aid security systems or can be fine-tuned to detect even smaller objects. Wondering how to get started? No worries, we’ll […]

Large Action Models (LAMs) vs Agentic LLMs: What’s the Real Difference?

Sree Vamsi — Fri, 03 Jul 2026 18:28:00 +0000

You tell your AI “Polish my email and send it.” Same sentence, three outcomes. The gap between Large Action Models (LAMs) and agentic LLMs is one of the most practically important distinctions in AI today, and also one of the least clearly explained. In this article, we cut through the confusion through a simple breakdown […]
