Overcoming Incomplete Perception with Util Distinction Memory

چکیده

This paper presents a method by which a reinforcement learning agent can solve the incomplete perception problem using memory. The agent uses a hidden Markov model (HMM) to represent its internal state space and creates memory capacity by splitting states of the HMM. The key idea is a test to determine when and how a state should be split: the agent only splits a state when doing so will help the agent predict utility. Thus the agent can create only as much memory as needed to perform the task at hand|not as much as would be required to model all the perceivable world. I call the technique UDM, for Utile Distinction Memory.

Relationship between Working Memory, Auditory Perception and Speech Intelligibility in Cochlear Implanted Children of Elementary School

Objectives: This study examined the relationship between working and short-term memory performance, and their effects on cochlear implant outcomes (speech perception and speech production) in cochlear implanted children aged 7-13 years. The study also compared the memory performance of cochlear implanted children with their normal hearing peers. Methods: Thirty-one cochlear impl...

Categorical perception of spatial relations across languages: The case of support

Cross-language differences in spatial language are not always reflected in nonlinguistic spatial representations. For example, the distinction between support and non-support relations among objects is obligatorily marked by basic spatial terms in English (”on” vs. ”above”), but not in Korean – yet spatial memory is sensitive to this distinction for speakers of both languages. Here, we provide ...
