Anomaly Detection of Wind Turbine Time Series using Variational Recurrent Autoencoders

1 code implementation5 Dec 2021 Alan Preciado-Grijalva, Victor Rodrigo Iza-Teran

Ice accumulation in the blades of wind turbines can cause them to describe anomalous rotations or no rotations at all, thus affecting the generation of electricity and power output.

Pre-trained Models for Sonar Images

1 code implementation2 Aug 2021 Matias Valdenegro-Toro, Alan Preciado-Grijalva, Bilal Wehbe

Machine learning and neural networks are now ubiquitous in sonar perception, but it lags behind the computer vision field due to the lack of data and pre-trained models specifically for sonar images.

Speaker Fluency Level Classification Using Machine Learning Techniques

2 code implementations31 Aug 2018 Alan Preciado-Grijalva, Ramon F. Brena

Level assessment for foreign language students is necessary for putting them in the right level group, furthermore, interviewing students is a very time-consuming task, so we propose to automate the evaluation of speaker fluency level by implementing machine learning techniques.
