This foundational module ensures proficiency in the Python programming language, emphasizing its application within the data science ecosystem. The focus extends beyond basic syntax to cover essential Pythonic concepts such as function definition, object-oriented programming basics, and handling various data structures. Learners will master efficient data handling techniques, including file input/output (I/O) for different formats (CSV, JSON), error handling using try...except blocks, and list comprehensions. This ensures a solid, efficient programming base required for subsequent data manipulation and modeling stages.
This module introduces the two cornerstone libraries of the Python data stack: NumPy for numerical computation and Pandas for data manipulation and analysis. We begin with NumPy, focusing on efficient array creation, indexing, and crucial concepts like vectorization, which dramatically speeds up mathematical operations compared to native Python lists. We then transition to Pandas, mastering the use of DataFrames and Series. Key skills covered include data loading, cleaning (handling missing values, duplicates), transformation (grouping, merging, pivoting), and robust data selection techniques critical for preparing raw datasets for machine learning.
Effective communication of data findings is the focus of this module. Learners will gain expertise in creating compelling visualizations using Matplotlib for granular control and Seaborn for high-level statistical plotting. The module covers the anatomy of a plot, customizing aesthetics, and selecting appropriate visualizations based on data type and analytical goal (e.g., line plots for trends, histograms for distributions, scatter plots for relationships). A major emphasis is placed on Exploratory Data Analysis (EDA), using visualization to uncover patterns, identify outliers, and detect feature relationships before initiating formal modeling.
This core module delves into the theoretical and practical application of foundational Machine Learning (ML) algorithms. We focus on two primary supervised learning tasks: Regression (predicting a continuous value) and Classification (predicting a categorical label). Key algorithms covered include Linear Regression, Logistic Regression, and Decision Trees. Learners will master the complete ML workflow: feature scaling, data splitting (train/test sets), model training, and crucial model evaluation metrics (e.g., R-squared, Precision, Recall, F1-Score). This module is critical for understanding how to select and train the right model for a given business problem.
The final module integrates all previous skills by introducing the fundamental concepts of taking a trained ML model out of the development environment and into a production setting (Model Deployment). This includes topics like model serialization (e.g., using Pickle), simple API creation (e.g., using Flask or Streamlit concepts), and the necessary environment management. The module culminates in a Mini Project, where learners will execute the entire data science pipeline: from loading a raw dataset, performing EDA and cleaning, training an appropriate ML model (either regression or classification), evaluating its performance, and presenting the final insights.
