The Aesthetics Of Multicoding Esolangs, Daniel J. Temkin

Electronic Literature Organization Conference 2020

In the influential 2005 paper "A Box, Darkly," Michael Mateas and Nick Montfort introduced the idea of multicoding: when one text holds multiple meanings, depending on context. Examples include polyglots, programs that can run successfully in two different languages, as well as sentences that can be read in French or English. Esoteric programming has a history of explicit multicoding languages. The best known are Piet, whose programs are images, and commands are the change in color from one pixel to the next; Shakespeare, with code written as plays, and Chef, whose programs are recipes that work in the kitchen. While …

Face Recognition Method Based On Cost-Sensitive Supervised Manifold Learning, Yeqin Cui, Jianguo Gao

Journal of System Simulation

Abstract: Existing subspace learning-based face recognition methods assume the same loss from all misclassifications. In the real-world face recognition applications, however, different misclassifications can lead to different losses.

The proposed approach incorporated a cost matrix to specify the different costs associated with misclassifications of subjects, into locality preserving projection algorithm, which devised the corresponding cost-sensitive methods, namely, cost-sensitive locality preserving projections (Cos-Sen LPP), to achieve a minimal overall loss. Three face databases were put into the experiments and experimental results show that Cos-Sen LPP method …
