Adversarial AI
نویسنده
چکیده
In recent years AI research has had an increasing role in models and algorithms for security problems. Game theoretic models of security, and Stackelberg security games in particular, have received special attention, in part because these models and associated tools have seen actual deployment in homeland security and sustainability applications. Stackelberg security games have two prototypical features: 1) a collection of potential assets which require protection, and 2) a sequential structure, where a defender first allocates protection resources, and the attacker then responds with an optimal attack. I see the latter feature as the major conceptual breakthrough, allowing very broad application of the idea beyond physical security settings. In particular, I describe three research problems which on the surface look nothing like prototypical security games: adversarial machine learning, privacy-preserving data sharing, and vaccine design. I describe how the second conceptual aspect of security games offers a natural modeling paradigm for these. This, in turn, has two important benefits: first, it offers a new perspective on these problems, and second, facilitates fundamental algorithmic contributions for these domains.

Toward a Research Agenda in Adversarial Reasoning: Computational Approaches to Anticipating the Opponent's Intent and Actions
This paper defines adversarial reasoning as computational approaches to inferring and anticipating an enemy's perceptions, intents and actions. It argues that adversarial reasoning transcends the boundaries of game theory and must also leverage such disciplines as cognitive modeling, control theory, AI planning and others. To illustrate the challenges of applying adversarial reasoning to real-w...
متن کاملBeyond Adversarial: The Case for Game AI as Storytelling
As a field, artificial intelligence (AI) has been applied to games for more than 50 years, beginning with traditional two-player adversarial games like tic-tac-toe and chess and extending to modern strategy games, first-person shooters, and social simulations. AI practitionershave become adept at designing algorithms that enable computers to play games at or beyond human levels in many cases. I...

Megapixel Size Image Creation using Generative Adversarial Networks
Since its appearance, Generative Adversarial Networks (GANs) [2] have received a lot of interest in the AI community. In image generation several projects showed how GANs are able to generate photorealistic images but the results so far didn’t look adequate for the quality standard of visual media production industry. We present an optimized image generation process based on a Deep Convolutiona...
متن کاملGame AI as Storytelling
Historically, games have been played between human opponents. However, with the advent of the computer came the notion that one might play with or against a computational surrogate. Dating back to the 1950s with early efforts in computer chess, approaches to game artificial intelligence (AI) have been designed around adversarial, or zero-sum, games. The goal of intelligent game-playing agents i...
متن کاملThe Second Annual Real-Time Strategy Game AI Competition
Real-time strategy (RTS) games are complex decision domains which require quick reactions as well as strategic planning and adversarial reasoning. In this paper we describe the second RTS game AI tournament, which was held in June 2007, the competition entries that participated, and plans for next year’s tournament.
