I implemented a Decision Tree Classifier on the famous Iris dataset — a simple yet classic dataset used to classify iris flowers into three species (Setosa, Versicolor, and Virginica) based on petal and sepal measurements. 📊https://lnkd.in/gg4h2s-D Using Python and Scikit-learn, I trained the model and visualized how the decision tree makes predictions. It was fascinating to see how machine learning can “learn” patterns and display them so clearly! 🌼 🧩 Libraries used: scikit-learn, matplotlib 💻 Code available on GitHub: This small project helped me understand how Decision Trees split data, how models are trained and visualized, and gave me confidence to explore more advanced ML models next! #MachineLearning #Python #ScikitLearn #DataScience #AI #DecisionTree #IrisDataset #CodingJourney #LearningByDoing

🚀 Day 51 of #100DaysOfMachineLearning 🔹 Today’s Topic: Creating a Gradient Descent Class – Finding Intercept & Slope from Scratch! 👉 1. Objective: Today, I implemented a custom Python class to compute model parameters (slope and intercept) using Gradient Descent from scratch. The aim was to automate the update steps for linear regression and gain a deeper understanding of how the intercept term evolves during optimization. 👉 2. Key Steps: 1️⃣ Defined a GradientDescentRegressor class with methods for initialization, fitting, and prediction. 2️⃣ Implemented the update rule: θ := θ - α * ∇J(θ) 3️⃣ Used mean squared error (MSE) as the cost function. 4️⃣ Visualized how the intercept (bias) and slope (weight) converge over epochs. 👉 3. Insights Gained: ✅ The intercept plays a critical role in aligning the regression line correctly with data. ✅ Proper scaling of features improves gradient stability. ✅ Watching the cost drop consistently confirms correct gradient computation. 💡 “Building from scratch deepens understanding far beyond using built-in libraries.” 🔖 #MachineLearning #AI #DataScience #Python #DeepLearning #MLBeginners #GradientDescent
