## Overview

This repository is a collection of data-analytics course assignments, not one integrated application. The principal workflows are standalone analyses: load or prepare data, apply a domain-specific model or statistical method, and produce estimates, plots, or reports. The graph preserves the sampled cricket, community-detection, gene-expression, neuroscience, epidemic-modeling, and genomic-search work. Several assignment excerpts are partial, and the README gives no further capability details, so connections not visible in source are omitted.

Main entry points: [`Assignment #4/code/main.py`](https://github.com/nishantk-iisc/data-analytics/blob/main/Assignment%20%234/code/main.py) (Analysis Runner), [`Assignment #1/nishant_21495_Asst1.py`](https://github.com/nishantk-iisc/data-analytics/blob/main/Assignment%20%231/nishant_21495_Asst1.py) (Data Preparation), [`Assignment #4/code/line_fit.py`](https://github.com/nishantk-iisc/data-analytics/blob/main/Assignment%20%234/code/line_fit.py) (Line Fit Analysis), [`Assignment #6/Assignment6.py`](https://github.com/nishantk-iisc/data-analytics/blob/main/Assignment%20%236/Assignment6.py) (BWT Indexing)
