Supervised Learning with Quantum Measurements

2 code implementations2 Apr 2020 Fabio A. González, Vladimir Vargas-Calderón, Herbert Vinck-Posada

Prediction of the label for a new sample is made by performing a projective measurement on the bipartite system with an operator, prepared from the new input sample, and applying a partial trace to obtain the state of the subsystem representing the output.

Event detection in Colombian security Twitter news using fine-grained latent topic analysis

no code implementations19 Nov 2019 Vladimir Vargas-Calderón, Nicolás Parra-A., Jorge E. Camargo, Herbert Vinck-Posada

Our method is able to discover event-specific sets of news, which is the baseline to perform an extensive analysis of how people engage in Twitter threads on the different types of news, with an emphasis on security, violence and crime-related tweets.

Using machine learning and information visualisation for discovering latent topics in Twitter news

no code implementations21 Oct 2019 Vladimir Vargas-Calderón, Marlon Steibeck Dominguez, N. Parra-A., Herbert Vinck-Posada, Jorge E. Camargo

We propose a method to discover latent topics and visualise large collections of tweets for easy identification and interpretation of topics, and exemplify its use with tweets from a Colombian mass media giant in the period 2014--2019.
