 This Git repository contains the code that accompanies the research paper "t-viSNE: Interactive Assessment and Interpretation of t-SNE Projections". The details of the experiments and the research outcome are described in [the paper](https://doi.org/10.1109/TVCG.2020.2986996).
 
 **Note:** t-viSNE is optimized to work better for standard resolutions (such as 1440p/QHD (Quad High Definition) and 1080p). Any other resolution might need manual adjustment of your browser's zoom level to work properly.

 **Note**: This software is based on the bhtsne library, its native executable and the python interface that is used to call the native executable. This library is the official implementation of t-SNE, made by its authors. Using the exact same input data, different systems will generate slightly different outputs in this library, and such differences will propagate to our software.
 
+**Note:** As any other software, the code is not bug free. There might be limitations in the views and functionalities of the tool that could be addressed in a future code update.

 # Data Sets #
 All data sets used in the paper are in the `data` folder, formatted as comma separated values (csv). 
 Most of them are available online from the [UCI Machine Learning Repository](http://archive.ics.uci.edu/ml/index.php): Iris, Breast Cancer Wisconsin (Original), Pima Indians Diabetes, and SPECTF. We also used a custom-made data set with Gaussian clusters.

 # Usage #
-Below is an example of how you can get t-viSNE running using Python for both frontend and backend. The frontend is written in Javascript/HTML, so it could be hosted in any other web server of your preference. The only hard requirement (currently) is that both frontend and backend must be running on the same machine.
