Context

Due to privacy concerns, it is difficult to gather data. Thus, some researchers suggest that a synthetic dataset can be generated using a realworld dataset. In this project, we aim to generate synthetic data using the Breadcrumbs dataset.

Objective

This project consists of three steps:

  1. Implementation (or adaptation) of the synthetic data generation code proposed by Kulkarni et al. [3]. 
  2. Evaluation of the synthetic data generation usin the Breadcrumbs dataset.
  3. Improvements to the synthetic data generation code.

This subject is ONLY a Semester Project, and it is a guided project. 

If you want to learn more about the Breadcrumbs Dataset, we suggest you read the Breadcrumbs Paper [1] and Breadcrumbs Dataset Description [2].

Prerequisites

Students must be confident with their algorithms and machine learning. Preferred programming languages are Java and Python.
