Over the first 30 days, they focused on math foundations like gradient descent, then progressed through supervised learning, regularization, neural networks, and backpropagation. The developer plans to continue sharing updates, code, and lessons learned along the way.", "body_md": "Hey,\nI'm a web developer - building UIs with React, TypeScript, Tailwind, and modern web tools. A few months ago, I decided to step into Machine Learning.\nNo prior ML background. Just curiosity and basic Python knowledge.I started Andrew Ng’s Machine Learning Specialization and created my own study plan. Here’s what the first 30 days looked like — the concepts that clicked, the mistakes I made, and what surprised me most.\nWeek 1: Building the Math Foundation\nI started with prerequisites because they’re essential:\nConcept: Why Gradients Matter\nGradient descent is the engine behind almost all modern ML.\nImagine you’re trying to reach the bottom of a valley in the dark. The gradient tells you the direction and steepness of the slope. You take a small step downhill.\n(w = w - learning_rate * gradient)\nRepeat until you reach the minimum.\nThis simple idea powers neural networks, linear regression, and more.\nWeeks 2–3: Supervised Learning (The Real Fun Begins)\nI dove into regression and classification:\nI built small projects in Colab:\nConcept: Regularization\nRegularization is like putting guardrails on your model. Without it, the model can memorize noise in the training data (overfitting). With L2 regularization, we penalize large weights, helping the model generalize better.\nWeeks 4–5: Neural Networks & Tree Ensembles\nThis is where things got exciting:\nConcept: Backpropagation\nForward propagation makes a prediction.\nBackpropagation figures out why the prediction was wrong and updates every weight accordingly using the chain rule. It’s like tracing a bug through a chain of React components — but for thousands of parameters.\nWhat Surprised Me Most\nWhat’s Next?\nI’m continuing the plan:\nI’ll be sharing regular updates here — code, lessons, and notebooks. If you’re also learning ML as a web developer, drop a comment. I’d love to hear your journey too!", "url": "https://wpnews.pro/news/im-a-front-end-web-developer-learning-machine-learning-from-scratch", "canonical_source": "https://dev.to/nasirovelchin/im-a-front-end-web-developer-learning-machine-learning-from-scratch-33n6", "published_at": "2026-05-23 06:52:42+00:00", "updated_at": "2026-05-23 07:01:23.458973+00:00", "lang": "en", "topics": ["machine-learning", "artificial-intelligence"], "entities": ["Andrew Ng", "React", "TypeScript", "Tailwind", "Colab"], "alternates": {"html": "https://wpnews.pro/news/im-a-front-end-web-developer-learning-machine-learning-from-scratch", "markdown": "https://wpnews.pro/news/im-a-front-end-web-developer-learning-machine-learning-from-scratch.md", "text": "https://wpnews.pro/news/im-a-front-end-web-developer-learning-machine-learning-from-scratch.txt", "jsonld": "https://wpnews.pro/news/im-a-front-end-web-developer-learning-machine-learning-from-scratch.jsonld"}}
