Data Science Skills Strengthened with Machine Learning Workflows

Over the past few months, I’ve been focused on strengthening my applied data science and machine learning engineering skills by working on end-to-end machine learning workflows using real-world datasets. Here’s a breakdown of what I’ve implemented: 🔹 Data Preprocessing & Cleaning • Handled missing data using interpolation and imputation techniques. • Detected and treated outliers using statistical methods. • Performed type conversions and data validation for consistency. 🔹 Exploratory Data Analysis (EDA) • Conducted univariate and multivariate analysis. • Identified correlations and feature relationships • Built visualizations using Pandas, Matplotlib, and Seaborn. 🔹 Feature Engineering • Created derived variables to improve signal extraction. • Applied encoding techniques for categorical variables. • Scaled and normalized features for model compatibility. 🔹 Model Development • Implemented supervised learning models including Linear Regression as a baseline model and other models like Decision Tree Classifier, Support Vector Machine Classifier, and Random Forest Classifier as comparison models. • Applied time series forecasting techniques for sequential data Structured pipelines for reproducibility. 🔹 Model Evaluation & Validation • Used metrics such as RMSE, accuracy, precision, F1 score and recall to check for model accuracy and performance. • Performed cross-validation to ensure model generalization. • Tuned hyperparameters to optimize model performance. 🔹 Project Highlight: Customer Churn Prediction • Built a predictive model to identify at-risk customers. • Engineered behavioral features to improve predictive power. • Generated actionable insights to support retention strategies This journey has strengthened my ability to translate raw data into scalable, data-driven solutions and actionable insights. #DataScience #MachineLearning #Python #EDA #FeatureEngineering #ModelEvaluation #AI #OpenToWork
