ITP-216 Applied PythonPython

Java Python ITP-216 Applied Python

Final Project

Definition/Description

In the era of Big Data, data analysis and visualization is the best approach for extracting useful information and making decisions.

For your Final Project, you are tasked with creating a web app which manipulates and visualizes a Big Data dataset.

Requirements

General

Your web app shall be written in Python using Flask, pandas, scikit-learn, and matplotlib.

Your web app shall allow clients to choose what subsets of the data they would like to see (via text input, radio buttons, et al.), and the app will serve them a visualization of that data.

Big Data

You may use any dataset of your choice for your Big Data; follow your heart! It must, however, meet the following criteria:

1.   It must contain at least 1000 datapoints.

2.   At least half of the data must be numeric.

Your Big Data shall be stored on your server. It may be stored as a csv. For extra credit, your Big Data shall be stored in a database which your web app accesses.

Endpoints

Your web app should implement a number of endpoints.

1.   At least 2 endpoints used for GET requests,i.e. directly accessible by browsers (e.g. '/').

a.   At least 1 of these should be a dynamic endpoint created from a client POST request (e.g. for a web app which makes predictions on amounts of insects in a given area,  '/projection/butterflies' ).

2.   At least 2 endpoints used for POST requests,i.e. not directly accessible by browsers (e.g. '/login'from the Web App Homework).

Scientific Computation

Your web app shall do some sort of computation with the Big Data dataset. This could be as straightforward as aggregating attributes, but it needs to compute something meaningful.

Machine Learning

Your web app shall make predictions based on the given Big Data dataset. As long as your web app is using ML to make predictions, you're good to go. These could be:

1.   Predictions of how a particular property will change over time.

2.   Label classifications of data with unknown labels.

Data Visualization

Your web app shall visualize the Big Data dataset in some meaningful way. At least two types of plots should be accessible:

1.   At least 1 plot should visualize the data without any ML processing.

2.   At least 1 plot should visualize ML-processed predictions. These plots do not all have to appear on the same webpage.

Provided Files/Data

Example project

An example of the Final Project from last semester can be found here: http://pohlner.pythonanywhere.com/

This project visualizes COVID-19 confirmed and recovered cases, and also visualizes ML predictions of future confirmed and recovered cases. It uses datasets from The Johns Hopkins University (JHU) Center for Systems Science and Engineering (CSSE), but only uses data up to mid-October.

*Example Project Usage Notes:

.    Make sure you’reusing Chrome or Firefox (not Safari or IE)

.    For Locale try “Mexico”  (case-sensitive)

.    For Date try “02/02/23” (format matters)

Grading

Section	Points (Total: 30)
Functionality and User Interface 1.   The root endpointshall display an input section for client-supplied data. 2.   Clients shall be able to select a query of existing data, or a prediction based on existing data. 3.   Clients shall be able to submit query information, which will generate a POST request. 4.   Clients shall be able to see queried information on returned pages.	4 (1 point each)
