Understanding RAG chunk size is critical for AI retrieval stability. This article breaks down how different chunking strategies—from small 80-character fragments to large 500-character blocks—impact the accuracy of your vector search. Learn how to refactor your text-splitting logic in PHP to avoid context loss and reduce AI hallucinations in your WordPress integrations.
Reinforcement Learning (RL) is transforming how LLMs reason, moving beyond “vibes” to verifiable logic. Senior developer Ahmad Wael explores the mechanics of RL training loops, formal verification, and synthetic dataset generation. Discover why a “Do or do not” reward system is the key to training models that actually think.
Stop treating AI like a black box. As a senior developer, mastering Hugging Face Transformers is essential for building scalable, cost-effective NLP tools. This guide covers the Pipeline API, sentiment analysis, and the critical importance of context windows when processing large datasets like resumes in a production environment.
When you transform random variables, substitution isn’t enough. Ahmad Wael explains the Jacobian adjustment—the critical scaling factor that prevents your data distributions from lying. Learn the intuition behind “sand on a rubber sheet” and see why the Jacobian factor is essential for honest reporting and image processing logic.
Feeling stuck in your current tech role? Don’t delete your career and start over. A successful tech career pivot is about refactoring your existing skills—like problem-solving and systems thinking—into new roles like Product Management or Advocacy. Learn how to leverage your legacy experience to move forward without losing your professional momentum.
Stop relying on bloated WooCommerce plugins for customer reporting. Ahmad Wael explains how to implement RFM Analysis (Recency, Frequency, Monetary) using Pandas to segment your customers accurately. Learn the technical logic behind ranking your best customers and winning back at-risk buyers without slowing down your WordPress database.
Stop wasting budget on heavy LLMs for simple tasks. Ahmad Wael explains why GliNER2 is the pragmatic choice for structured data extraction. Learn how to handle entity recognition and relationship mapping on a CPU without the high costs or latency of major AI APIs. Get the right tool for the job.
Stop making excuses for poor model performance. Learn how to handle covariance shift using Inverse Probability Weighting (IPW). Senior dev Ahmad Wael explains how to re-weight your validation data to match real-world production distributions, ensuring your machine learning models stay accurate even when user demographics shift unexpectedly. No more apples-to-oranges comparisons.
Is your machine learning model struggling with time-based predictions? Learn how cyclical feature encoding uses Sine and Cosine transformations to fix the “midnight paradox.” Stop treating time like a straight line and start mapping it to a circle to preserve proximity and improve model accuracy for WooCommerce and data-heavy WordPress sites.
Stop wasting your server’s multi-core power. Learn how to master Distributed Computing with Ray to scale your Python scripts from one core to sixty-four with minimal code changes. Ahmad Wael shares a real-world story of fixing a client’s slow data pipeline and why Ray is the pragmatic choice over standard multiprocessing.
