🐍 Day 95 — Model Evaluation (Mean Squared Error) Day 95 of #python365ai 📏 Evaluate models using metrics like MSE. Example: from sklearn.metrics import mean_squared_error 📌 Why this matters: We need to measure how good a model is. 📘 Practice task: Compute error for predictions. #python365ai #ModelEvaluation #ML #Python

🚀 Day 52/100 – Python, Data Analytics & Machine Learning Journey 🤖 Module 3: Machine Learning 📚 Today’s Learning: Supervised Learning – Regression Algorithm 4: KNN Regression Today, I explored K-Nearest Neighbors (KNN) Regression, a simple yet powerful supervised machine learning algorithm used for predicting continuous values. KNN Regression works by identifying the ‘K’ nearest data points to a given input and predicting the output as the average (or weighted average) of those neighbors. KNN is widely used in applications like recommendation systems, pattern recognition, and demand forecasting. The learning journey continues as I explore more regression algorithms and their real-world applications. 📌 Code & Notes: https://lnkd.in/dmFHqCrK #100DaysOfPython #MachineLearning #AIML #Python #LearningInPublic #DataScience

📊 Day 4 | Linear Regression 📈📉 Today, I learned about Linear Regression, one of the simplest and most widely used Machine Learning algorithms. It is used to predict a continuous value based on input data. The idea is to find a straight line (best fit line) that represents the relationship between variables. 📌 Example: Predicting product price based on cost or features. To understand this, I implemented a simple Linear Regression model using Python 💻 This helped me see how machines can learn patterns and make predictions. Linear Regression is often the first step into Machine Learning models 📊 #MachineLearning #LinearRegression #DataScience #LearningInPublic #Python
