Semantic Image Collection Summarization with Frequent Subgraph Mining
Applications such as providing a preview of personal albums (e.g., Google Photos) or suggesting thematic collections based on user interests (e.g., Pinterest) require a semantically-enriched image representation, which should be more informative with respect to simple low-level visual features and image tags. To this aim, we propose an image collection summarization technique based on frequent subgraph mining. We represent images with a novel type of scene graphs including fine-grained relationship types between objects. These scene graphs are automatically derived by our method. The resulting summary consists of a set of frequent subgraphs describing the underlying patterns of the image dataset. Our results are interpretable and provide more powerful semantic information with respect to previous techniques, in which the summary is a subset of the collection in terms of images or image patches. The experimental evaluation shows that the proposed technique yields non-redundant summaries, with a high diversity of the discovered patterns
Advancing Perception in Artificial Intelligence through Principles of Cognitive Science
Although artificial intelligence (AI) has achieved many feats at a rapid
pace, there still exist open problems and fundamental shortcomings related to
performance and resource efficiency. Since AI researchers benchmark a
significant proportion of performance standards through human intelligence,
cognitive sciences-inspired AI is a promising domain of research. Studying
cognitive science can provide a fresh perspective to building fundamental
blocks in AI research, which can lead to improved performance and efficiency.
In this review paper, we focus on the cognitive functions of perception, which
is the process of taking signals from one's surroundings as input, and
processing them to understand the environment. Particularly, we study and
compare its various processes through the lens of both cognitive sciences and
AI. Through this study, we review all current major theories from various
sub-disciplines of cognitive science (specifically neuroscience, psychology and
linguistics), and draw parallels with theories and techniques from current
practices in AI. We, hence, present a detailed collection of methods in AI for
researchers to build AI systems inspired by cognitive science. Further, through
the process of reviewing the state of cognitive-inspired AI, we point out many
gaps in the current state of AI (with respect to the performance of the human
brain), and hence present potential directions for researchers to develop
better perception systems in AI.Comment: Summary: a detailed review of the current state of perception models
