We examine the problem of learning and planning on highdimensional domains with long horizons and sparse rewards. Recent approaches have shown great successes in many Atari 2600 domains. However, domains with long horizons and sparse rewards, such as Montezuma’s Revenge and Venture, remain challenging for existing methods. Methods using abstraction (Dietterich 2000; Sutton, Precup, and Singh 19...

Recently, reinforcement learning has been successfully applied to the logical game of Go, various Atari games, and even a 3D game, Labyrinth, though it continues to have problems in sparse reward settings. It is difficult to explore, but also difficult to exploit, a small number of successes when learning policy. To solve this issue, the subgoal and option framework have been proposed. However,...

Design-for-Assembly (DFA) analysis of a product may indicate shortcomings of a design, without providing \speciic" guidance on redesigns for solving the problem. This paper introduces a computational tool, in development at USC, for assisting redesigns of mechanical asssemblies for DFA. The system, named REVENGE , is based on a model of reverse engineering in order to incorporate design rationa...

Detecting signs that someone is a member of a hostile outgroup can depend on very subtle cues. How do ecology-relevant motivational states affect such detections? This research investigated the detection of briefly-presented enemy (versus friend) insignias after participants were primed to be self-protective or revenge-minded. Despite being told to ignore the objectively nondiagnostic cues of e...

Blood revenge is one of the most commonly cited causes of violence and warfare in tribal societies, yet it is largely ignored in recent anthropological theories of primitive warfare. A theory of tribal violence is presented showing how homicide, revenge, kinship obligations, and warfare are linked and why reproductive variables must be included in explanations of tribal violence and warfare. St...

The present study examined coping strategies for cyber victimization among 270 (130 women) emerging adults, and how these strategies related to cyber aggression one year later (Time 2). The most frequently utilized coping strategies among emerging adults were telling one’s friends and ignoring the aggressor. The coping strategies of telling no one, getting revenge against the aggressor, pretend...

In this fake paper we introduce the virtual glasses that allow myopic or hyperopic people to see a sharp image without wearing glasses. Virtual glasses improve existing image preconditioning methods by making use of the recent advances in computer graphic and image processing. Thanks to virtual glasses, myopic people will finally be able to have a sharp vision of the world, while still being go...
