Proto-Value Networks: Scaling Representation Learning with Auxiliary Tasks [PDF]
International Conference on Learning Representations, 2023 Auxiliary tasks improve the representations learned by deep reinforcement learning agents. Analytically, their effect is reasonably well understood; in practice, however, their primary use remains in support of a main learning objective, rather than as a

Proto-CLIP: Vision-Language Prototypical Network for Few-Shot Learning [PDF]
IEEE/RJS International Conference on Intelligent RObots and Systems, 2023 We propose a novel framework for few-shot learning by leveraging large-scale vision-language models such as CLIP [1]. Motivated by unimodal prototypical networks for few-shot learning, we introduce Proto-CLIP which utilizes image prototypes and text ...

From Clusters to Proto-Clusters: The Infrared Perspective on Environmental Galaxy Evolution [PDF]
Universe, 2022 Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it can control the critical process of transforming galaxies from star forming to quiescent, commonly termed “quenching”. Despite its importance, however, we still do

Event-driven proto-object based saliency in 3D space to attract a robot’s attention
Scientific Reports, 2022 To interact with its environment, a robot working in 3D space needs to organise its visual input in terms of objects or their perceptual precursors, proto-objects.

Oncogenes, Proto-Oncogenes, and Lineage Restriction of Cancer Stem Cells
International Journal of Molecular Sciences, 2021 In principle, an oncogene is a cellular gene (proto-oncogene) that is dysfunctional, due to mutation and fusion with another gene or overexpression. Generally, oncogenes are viewed as deregulating cell proliferation or suppressing apoptosis in driving ...
