MAT-similarity: Similarity Methods and Functions for Multiple Aspect Trajectory Data Mining [MAT-Tools Framework]

---

[Publication] [Bibtex] [GitHub] [PyPi]

The present application offers a tool, to support the user in the data mining task of multiple aspect trajectories, specifically for measuring similarity of its complex data. It integrates into a unique platform the fragmented approaches available for multiple aspects trajectories and in general for multidimensional sequence classification into a unique web-based and python library system.

Main Modules

The implemented similarity measure classes for MAT:

1. MUITAS: Semantic-Aware Multiple-Aspect Trajectory Similarity measure.

2. MSM: Multidimensional similarity measuring for semantic trajectories.

3. LCSS: Longest Common Subsequence MAT similarity measure.

4. EDR: Edit Distance on Real sequences MAT similarity measure.

Installation

Install directly from PyPi repository, or, download from github. (python >= 3.7 required)

    pip install mat-similarity
