Multiple-Linear-Regression This work presents a Machine Learning project developed in Python, designed to predict the median value of owner-occupied homes in the Boston metropolitan area (USA) using the well-known Boston Housing dataset. Problem: Estimate prices based on multiple socieconomic, environmental, and structural variables. Solution: Built a Multiple Linear Regression model and applied Principal Component Analysis (PCA) to deal multicollinearity by transforming correlated predictors into independent components, reducing dimensionality while preserving most of the data variance. The final model was trained using Gradient Descent optimization. The Jupyter Notebook containing the full implementation and analysis is available at the following link: https://lnkd.in/dtP6pzdS #Python #MachineLearning #DataScience #LinearRegression #PCA #PredictiveModeling #PowerBI #Jupyter #R

📊 Why NumPy Matters in Python NumPy is more than just an array library — it’s the foundation of most data-driven work in Python. From efficient numerical computations to vectorized operations, NumPy enables faster, cleaner, and more reliable data processing. Understanding how NumPy handles memory, broadcasting, and array operations helps write code that is not only correct but also performant. In Data Science and Machine Learning, strong NumPy fundamentals often matter more than complex models. Clean data operations lead to trustworthy results. Building with clarity. Optimizing with purpose. #NumPy #Python #DataScience #MachineLearning #NumericalComputing #CleanCode #DeveloperGrowth

PB Week 5 – Learning Reflection This week, I learned how data visualization using Python helps uncover patterns and insights during exploratory data analysis. By working with Matplotlib and Seaborn, I realized that even simple charts can provide valuable understanding when used with the right purpose. I’ve summarized this learning in a short slide deck. Feel free to check it out. Digital Skola #DigitalSkola #LearningProgressReview #DataAnalytics #Python #DataVisualization

Day 06 of my NumPy Revision ✅ Today I revised how to handle missing (NaN) and infinite values using NumPy. These concepts are very important for data preprocessing and machine learning. ✔ np.isnan() – detect missing values ✔ np.nan_to_num() – replace NaN and infinite values ✔ np.isinf() – detect infinite values ✔ np.isfinite() – validate clean numeric data I am documenting my complete learning journey step-by-step on GitHub. More revisions coming soon on Pandas #NumPy #DataScience #Python #MachineLearning #LearningJourney #GitHubPortfolio
