We have an ambition towards higher levels of understanding the situations that are shown in images. For instance, a few people that form a group, which can be seen by whether they are looking at each other. Another example is that one person carries a bag and gives it to another person. We want to define such situations by first-order logic (symbolic predicates), and analyze them by recognizing the symbols in the image by deep learning models. The worlds of symbolic logical statements and machine/deep learning can be connected by a recent method called neurosymbolic programming. We want to explore this method for situation understanding.
What will be your role?
We hypothesize that neuro-symbolic programming can be very valuable for situation understanding. That is, to define a situation by a particular combination of objects, e.g., a gathering involves multiple people standing close together (symbolic statement), measured by detections of the persons in the scene and features that can be pooled from them (neural network).
In the original paper, https://scallop-lang.github.io, it is possible to define the sum of two digits (symbolic statement), where each digit is perceived by an image (neural network). Together they form a neurosymbolic program. From the high-level definition of the sum, any mistakes by the neurosymbolic program are measured by a loss, which can backpropagate all the way to the digit neural network, to improve on the task of sum prediction.
Situation understanding is more complex. Consider group formation: a loss may promote that the persons’ features indeed indicate that they are facing at each other, i.e., that they are a social group. The goal of your research is to explore neuro-symbolic programming combined with deep learning for situation understanding.
