We study the e↵ect of source and type of training data on detecting failures in industrial robots using Principal Component Analysis (PCA). Specifically, using field data across multiple robots performing di↵erent tasks, we compare two scenarios: first, where training data obtained from a single robot is used to evaluate multiple robots (one-to-many), and second, where each robot is evaluated o...

Abstract In this paper, we report on PIN-code typing behaviour touchscreen devices of 112 subjects. Detailed statistical analysis revealed that the major di erence between subjects is in inter-key latency. Key-press duration variations are insignificant compared to latency variations. Subjects were grouped into meaningful clusters using clustering. The resulting slow, medium, and fast typists. ...

objective: early recognition of negative emotions is considered to be of vital importance. it seems that children with attention deficit hyperactivity disorder have some difficulties recognizing facial emotional expressions, especially negative ones. this study investigated the preference of children with attention deficit hyperactivity disorder for negative (angry, sad) facial expressions comp...

This paper presents an assignment model of CEOs and …rms. The distributions of CEO pay levels and …rms’market values are analyzed as the competitive equilibrium of a matching market where talents, as well as CEO positions, are scarce. It is shown how the observed joint distribution of CEO pay and market value can then be used to infer the economic value of underlying ability di¤erences. The var...

We introduce the rst algorithm for o -policy temporal-di erence learning that is stable with linear function approximation. O policy learning is of interest because it forms the basis for popular reinforcement learning methods such as Q-learning, which has been known to diverge with linear function approximation, and because it is critical to the practical utility of multi-scale, multi-goal, le...

Wepresent a systemfor verifyingthe timing speci cations of digital interfaces. The systemis based on a static analysis of the temporal protocols on the control signals whichmake up the interface. Veri cationis performedbycheckingthat nocausal chainof events onthe control signals violates any of the protocol constraints on those same signals. While the systemdoes not performanychecking of functi...

We develop an algorithm for the traveling salesman problem by applying nite diierences to a generating function. This algorithm requires polynomial space. In comparison, a dynamic programming algorithm requires exponential space. Also, the nite-diierence algorithm requires less space than a similar inclusion and exclusion algorithm.

Fractional advection–dispersion equations are used in groundwater hydrology to model the transport of passive tracers carried by uid ow in a porous medium. In this paper we develop practical numerical methods to solve one dimensional fractional advection–dispersion equations with variable coe1cients on a 2nite domain. The practical application of these results is illustrated by modeling a radia...
