A framework to compare music generative models using automatic evaluation metrics extended to rhythm

1 code implementation19 Jan 2021 Sebastian Garcia-Valencia, Alejandro Betancourt, Juan G. Lalinde-Pulido

To train a machine learning model is necessary to take numerous decisions about many options for each process involved, in the field of sequence generation and more specifically of music composition, the nature of the problem helps to narrow the options but at the same time, some other options appear for specific challenges.

Egoshots, an ego-vision life-logging dataset and semantic fidelity metric to evaluate diversity in image captioning models

2 code implementations26 Mar 2020 Pranav Agarwal, Alejandro Betancourt, Vana Panagiotou, Natalia Díaz-Rodríguez

In this paper, we attempt to show the biased nature of the currently existing image captioning models and present a new image captioning dataset, Egoshots, consisting of 978 real life images with no captions.
