Rapid advances in image processing capabilities have been seen across many domains, fostered by the application of machine learning algorithms to "big-data". However, within the realm of medical image analysis, advances have been curtailed, in part,... Read More about A Survey of Crowdsourcing in Medical Image Analysis.

Rethinking the definition of episodic memory. (2020)
Journal Article
Madan, C. R. (2020). Rethinking the definition of episodic memory. Canadian Journal of Experimental Psychology, 74(3), 183-192. https://doi.org/10.1037/cep0000229

The definition of episodic memory, as proposed by Tulving, includes a requirement of conscious recall. As we are unable to assess this aspect of memory in nonhuman animals, many researchers have referred to demonstrations of what would otherwise be c...

Video games are sometimes used as environments to evaluate AI agents’ ability to develop and execute complex action sequences to maximize a defined reward. However, humans cannot match the fine precision of the timed actions of AI agents; in games su... Read More about Considerations for comparing video-game AI agents with humans.

We tested two possible mechanisms underlying this impairment, usin... Read More about Reduced associative memory for negative information: impact of confidence and interactive imagery during study.
