Recent Projects

Industrial Drone Startup Company
Structural Fault Detection
Developed a system using a mix of traditional computer vision techniques and deep learning techniques to detect faults such as cracks in industrial installations. The data was from videos captured from large drones.

Social Media Analysis Company
Geographical Inference from Social Media Posts
Analyzed both the text and imagery of social media posts to determine if they give hints at where the person posting is physically located. A deep learning computer vision approach was used to detect clearly identifiable landmarks in the backgrounds of photos. Also, with a pre-trained hybrid bi-directional LSTM and conditional random field model, named entities were identified and extracted from the foreign language text documents.
