This paper uses a modified Ant Colony Optimization (ACO) algorithm to price simple financial derivatives. We use ants to find the optimum time to exercise an option. Our algorithm searches the solution space to find optimum solution under some user defined constraints. In this preliminary study we show that the modified ACO works in predicting an optimum exercise time of a simple vanilla option.

In this paper, we develop improved techniques for defending against adversarial examples at scale. First, we implement the state of the art version of adversarial training at unprecedented scale on ImageNet and investigate whether it remains effective in this setting—an important open scientific question (Athalye et al., 2018). Next, we introduce enhanced defenses using a technique we call logi...
