Full Unit-wise Syllabus

Unit I – Introduction, Toolboxes

Python, fundamental libraries for data Scientists. Integrated development environment (IDE). Data operations: Reading, selecting, filtering, manipulating, sorting, grouping, rearranging, ranking, and plotting

Practical: Data Analysis and Visualization using Python or MATLAB

Activities: Load a dataset and perform basic data operations like filtering, sorting, and grouping using Pandas. Visualize insights using plots with Matplotlib or Seaborn.

Unit II – Descriptive statistics and data preparation

Exploratory Data Analysis data summarization, data distribution, measuring asymmetry. Sample and estimated mean, variance and standard score. Statistical Inference frequency approach, variability of estimates, hypothesis testing using confidence intervals, using values.

Practical: Descriptive Statistics and Hypothesis Testing Python or MATLAB

Activities: Perform Exploratory Data Analysis on a dataset to summarize key features using mean, median, and variance. Visualize data distribution and asymmetry using histograms and box plots.

Unit III – Supervised Learning

First step, learning curves, training-validation and test. Learning models generalities, support vector machines, random forest. Examples.

Practical: Supervised Learning Model Implementation and Evaluation using Python or

Unit IV – MATLAB

Activities: Study on performance metrics to understand model generalization.

Unit V – Regression analysis

Regression: simple linear regression, multiple & Polynomial regression, Sparse model. Unsupervised learning, clustering, similarity and distances, quality measures of clustering, case study.

Practical: Regression and Clustering Analysis using Python or MATLAB

Activities: Apply Simple Linear Regression, multiple, and polynomial regression models to understand relationships between variables. Compare model performance and interpret coefficients to analyze prediction accuracy.

Unit VI – Network Analysis

Graphs, Social Networks, centrality, drawing centrality of Graphs, PageRank, Ego-Networks, community Detection.

Practical: Graph Analysis and Community Detection using Python or MATLAB

Activities: Explore basics of Network Analysis by representing data as graphs with nodes and edges. Compute centrality measures (degree, closeness, betweenness) to identify important nodes.
