@Dipen
I am an AI/ML researcher with 150+ citations and 16 published research papers. I have three tier-1 publications, including Internet of Things (Elsevier), Biomedical Signal Processing and Control (Elsevier), and IEEE Access. In my research journey, I have collaborated with NASA Glenn Research Center, Cleveland Clinic, and the U.S. Department of Energy for various research projects. I am also an official reviewer and have reviewed over 100 research papers for Elsevier, IEEE Transactions, ICRA, MDPI, and other top journals and conferences. I hold a PhD from Cleveland State University with a focus on large language models (LLMs) in cybersecurity, and I also earned a master’s degree in informatics from Northeastern University.

Fine-Tuning LLMs for AI Inference
When you teach a general-purpose language model medical billing or customer service language, you are not hoping it understands your domain. You are making it do so. Fine-tuning turns vague, hallucination-prone outputs into systems that generate structured data, enforce compliance rules, and match…Aug 18th 2026
From Prompt Engineering to Context Engineering: Better Patterns for Real AI Applications
Most failures in a real AI application trace back to missing or messy context, not a weak model. When a production system "hallucinates," the prompt wording is rarely the culprit. It's what the model could and couldn't see at inference time. That changes how we teach lead developers. Prompt…Aug 18th 2026
LoRA vs QLoRA for LLM Fine-Tuning: VRAM, Quality, and Deployment Costs
The LoRA vs QLoRA decision comes down to VRAM budget versus quality. LoRA keeps the base model in full precision and trains small adapter matrices on top. It needs more memory, but it recovers most of what full fine-tuning gives you. QLoRA quantizes the frozen model to 4-bit first, which is why it…Aug 17th 2026
What Supabase Is Used for in RAG Apps: pgvector, Auth, and Edge Functions for AI Builders
Watch: Supabase Edge Functions Explained by Supabase Supabase suits RAG apps needing pgvector, authentication, and serverless functions together. If you're teaching bootcamp students to build AI apps, it reduces early infrastructure work. One Postgres instance stores application data, embeddings,…Aug 17th 2026
Stemming vs Lemmatization for LLM Pipelines: What Still Matters for RAG Search in 2025
This preprocessing choice happens before documents are indexed into the vector store. The two methods diverge in execution: one relies on algorithmic truncation rules, the other on grammatical rules to identify the base form of a word. This operational difference directly affects system design.…Aug 17th 2026
Use local AI Inference. AMD Ryzen Halo vs DGxSpark
Watch: Is STRIX Better than SPARK? Now Launching w/new Software: AMD's Ryzen AI Halo Developer Workstation by Level1Techs Local AI inference means running models on hardware you own, not paying per token to a cloud API. Two workstations lead this space right now: the AMD Ryzen AI Halo at $3,999 and…Aug 15th 2026python-dotenv with LiteLLM for Multi-Model AI Apps
If you're running multi-model AI in production, you've hit this problem: dozens of provider keys scattered across your codebase, rotation means grep-and-pray, and swapping models requires a pull request. Python-dotenv with LiteLLM fixes this by treating credentials as infrastructure config, not…Aug 12th 2026
Cursor vs v0 vs Lovable vs Augment Code for AI App Builds
Watch: I Ranked Every AI App Builder for 2026: Lovable vs. Bolt vs. Replit vs. Cursor (No Code) by Build Great Products Cursor differs fundamentally from the other tools in this comparison. It's not an app builder. Lovable, v0, and Bolt generate complete applications from prompts. Cursor is an…Aug 12th 2026
Hermes Agent vs Grok bot vs Openclaw
OpenClaw is designed to run locally—on machines ranging from Mac Minis to Raspberry Pis. It can connect to messaging platforms like WhatsApp, Telegram, Slack, Discord, and iMessage. The system is built to remember context from prior conversations, reducing the need to re-explain project setup.…Aug 12th 2026
Understanding the Three Core Layers of RAG Systems
Every production RAG system rests on three engineering layers: prompt, context, and loop. Get these three right and you understand why any RAG system works or breaks. The catch is that most tutorials show you the toy version, that tidy Query to Vector DB to LLM to Response diagram that hides where…Aug 10th 2026
What Is AI Inference in LLM Apps
Watch: AI Inference: The Secret to AI's Superpowers by IBM Technology Inference is where a trained model finally earns its keep. It's the moment your app sends a prompt and gets tokens back. Moving from a working notebook to a production service means your attention shifts from model accuracy to…Aug 10th 2026
What Is AI Application and How Developers Use It
Developers waste months building AI features that solve the wrong problem. The failure isn't technical. It's treating AI as the solution before you've understood what you're solving. Before you write a line of code, answer this: does this problem genuinely benefit from machine learning, or would a…Aug 10th 2026
What Is AI Applications and Common Examples for Developers
AI applications are software programs that use machine learning, natural language processing, and computer vision to handle tasks that once needed human judgment. They run in healthcare, finance, retail, and manufacturing right now. If you're a developer aiming at a lead role, the fastest path is a…Aug 7th 2026
How to Build AI Applications with RAG and Tool Use
Building AI applications with Retrieval‑Augmented Generation (RAG) follows a recognizable workflow. The table below summarises the typical questions of “what, how long, and how hard” for each major phase, along with tools that frequently appear in tutorials and open‑source projects. What does the…Aug 7th 2026
Spotify Developer Dashboard: How to Create and Configure Your App
The first step in connecting to Spotify's API is creating an app. That gives you API credentials. The process takes about five minutes, but the limits you hit later matter more than speed. You'll need a Spotify account to access the developer dashboard. Any account type works. Some tutorials…Aug 7th 2026
How Much Does Fine‑Tuning an LLM Really Cost?
Estimating the budget for adapting a large language model hinges on three factors: model size, training technique, and infrastructure pricing. Small models can be tuned with modest resources, while larger architectures demand a more detailed cost plan. Newline’s AI Bootcamp teaches students how to…Aug 4th 2026
Types of AI Agents and How They Work
Four core types of AI agents keep showing up in real projects: sequential, reactive, planning, and memory‑augmented. Newline's AI bootcamp maps each type to a project‑focused module, so you can pick the path that matches where you are right now. For routine, linear tasks like generating a static…Aug 4th 2026
Mastering Advanced RAG for Better AI Retrieval
Advanced RAG techniques turn prototype chatbots into production-grade retrieval systems. A basic RAG pipeline ingests documents, indexes them, retrieves top-k chunks, and generates answers. It works for low-stakes Q&A. It collapses under real-world pressure. Research shows that basic systems…Aug 4th 2026
What Is an AI Application? Examples, Patterns, and Use Cases
AI applications come in three broad shapes: single-call LLM solutions, workflow-based automations, and agentic systems. Each one balances cost, autonomy, and complexity in its own way. Pick the wrong one and the project stalls. In our experience, the model is rarely the culprit. Most enterprise LLM…Aug 3rd 2026
What Is AI Inference and Why It Matters for Apps
AI inference is the moment a trained model turns data into a decision. That single step powers every smart feature in a modern app. Newline's AI bootcamps include hands-on labs covering the inference setups you'll actually see in production. Here's the shortlist of the five modes the labs walk…Aug 3rd 2026
