Why Is My Neural Network Not Learning? Debugging Tips for ML Models

 If your neural network is producing poor results despite extensive training, you’re not alone. Debugging machine learning models is a crucial skill that separates beginners from experts.

Common Reasons and Fixes:

  1. Improper Learning Rate: Too high leads to unstable training, too low results in slow convergence.

  2. Vanishing/Exploding Gradients: Use batch normalization and activation functions like ReLU to maintain gradient stability.

  3. Poor Weight Initialization: Consider techniques like Xavier or He initialization to avoid gradient issues.

  4. Insufficient Data: If your dataset is too small, try using data augmentation or synthetic data generation.

  5. Overcomplicated Model: Reduce model complexity by decreasing layers or parameters if overfitting occurs.

Machine learning is an iterative process. By methodically addressing these issues, you can fine-tune your neural network and improve its performance significantly.

Behind the Scenes: How Generative AI Creates Music, Art, and Stories

When Machines Dream We’re living in a world where machines don’t just compute—they create. Generative AI is writing novels, composing symphonies, and painting pictures. But what’s really going on behind the screen? This post pulls back the curtain to reveal how generative AI actually creates —from writing a bedtime story to composing a lo-fi beat. Whether you're a curious creator or tech enthusiast, you’ll see the art of AI through a new lens. What is Generative AI, Really? Generative AI uses machine learning models—especially neural networks—to generate new content based on learned patterns. Trained on vast datasets, these models produce original music, images, and text based on user prompts. 1. How AI Writes Stories (e.g., ChatGPT, Claude) Step-by-step: You give a prompt: “Write a story about a lonely robot who finds a friend in the forest.” The model (like ChatGPT) draws on its training data to predict and generate the most likely next word, sentence, or paragr...

PromptCraft Series #1 : Blog series on the Art and Science of prompt engineering

Welcome to the Era of No-Code Prompt Engineering New post every Monday 🧠 What’s This Series About? Welcome to PromptCraft — your new favorite blog series dedicated to the art and science of prompt engineering for no-code platforms like Lovable , Replit , and more. Every Monday, we’ll dive deep into how non-developers and AI creators can craft powerful, accurate, and elegant prompts to build everything from chatbots and virtual assistants to internal tools, automations, and AI-powered apps — no coding required . Whether you're a startup founder, solopreneur, educator, content creator, or just a curious explorer, this series is for you. 🔍 What is Prompt Engineering? Prompt engineering is the process of crafting precise, structured, and smart inputs (prompts) that guide large language models (LLMs) like GPT-4 to produce useful, high-quality outputs. But unlike traditional coding, prompt engineering speaks the language of humans , not machines. It’s like programming in plai...

PromptCraft Blog Series #4: Crafting Prompts for Chatbots and Conversational AI.

."> PromptCraft Series #4 – Crafting Prompts for Chatbots ✨ PromptCraft Series #4 "Crafting Prompts for Chatbots and Conversational AI" 🗕️ New post every Monday ] 🤖 Why Chatbots Need Special Prompting Unlike one-shot tasks like generating summaries or captions, chatbots must think in conversations . Respond in real-time Maintain tone and personality Handle multiple topics Remember context across multiple turns Good prompt engineering makes this possible without code or training . 📊 Foundations of a Conversational Prompt "You are [name], a [role]. You respond in a [tone] tone. Your answers are [length/style]. When asked [topics], reply with [behavior]. You must remember: [rules/context]." ✨ Example 1: A Friendly AI Tutor You are Elan, an AI math tutor for high school students. You respond in a calm and encouraging tone. ...
