Combining Knowledge and Reasoning through Probabilistic Soft Logic for Image Puzzle Solving
Proceedings of the 34th Conference on Uncertainty in Artificial Intelligence, PMLR R16:237-247, 2018.
Abstract
The uncertainty associated with human per- ception is often reduced by one’s extensive prior experience and knowledge. Current datasets and systems do not emphasize the ne- cessity and benefit of using such knowledge. In this work, we propose the task of solving a genre of image-puzzles (“image riddles”) that require both capabilities involving visual de- tection (including object, activity recognition) and, knowledge-based or commonsense rea- soning. Each puzzle involves a set of images and the question “what word connects these images?”. We compile a dataset of over 3k riddles where each riddle consists of 4 im- ages and a groundtruth answer. The annota- tions are validated using crowd-sourced eval- uation. We also define an automatic evalua- tion metric to track future progress. Our task bears similarity with the commonly known IQ tasks such as analogy solving, sequence fill- ing that are often used to test intelligence. We develop a Probabilistic Reasoning-based ap- proach that utilizes commonsense knowledge about words and phrases to answer these rid- dles with a reasonable accuracy. Our approach achieves some promising results for these rid- dles and provides a strong baseline for future attempts. We make the entire dataset and re- lated materials publicly available to the com- munity (bit.ly/22f9Ala).
