Gravitational-Wave Optical Counterpart Detection Methods for the TOROS Campaign During LVC O2 Observation Run

In this talk we will discuss the current status of optical transient (OT) detection on astronomical images taken by the TOROS Collaboration during the LVC Observation Run O2. We review several Difference Image Analysis methods and traditional Machine Learning techniques used to clean up recovered transient candidates, as well as new OT detection methods based on Convolutional Neural Networks and the use of raw pixels of the image.
