Training Semantic Knowledge in Artificial Brains — or What the Heck is this AI Thing John’s Been Doing?!

As many of you know, I’ve been working on a MS degree in Artificial Intelligence on the side these past few years. My research has focused primarily on artificial neural networks and visual/semantic tasks, and this talk combines two presentations/publications from the past year. First, I present a statistical method for determining image “sameness” between two images--a method of improving on image-based recall of significant elements within a scene. For example, present an artificial brain with a picture of a lion, and get back other pictures of lions. Second, I will compare two methods of color correcting video sequences: one, a class-based method, the other a generative method. While color correction is a creative task that requires semantic understanding of the qualities of an image, a neural network can be trained to perform the task at near human levels. Overall, then, my work is about creating neural networks that “understand” the qualities of an image and can perform useful tasks on these images.
