Previous work has shown that spectro-temporal features reduce WER for automatic speech recognition under noisy conditions. The spectro-temporal framework, however, is not the only way to process features in order to reduce errors due to noise in the signal. The two-stage mel-warped Wiener filtering method used in the “Advanced Front End” (AFE), now a standard front end for robust recognition, i...

We examine the social prerequisites for symbolic communication by studying a language game embedded within a signaling game, in which cooperation is possible but unenforced, and agents have incentive to deceive. Despite this incentive, and even with persistent cheating, naming conventions can still arise from strictly local interactions, as long as agents employ sufficient mechanisms to detect ...

Liouville field theory on a unoriented surface is investigated, in particular, the one point function on a RP2 is calculated. The constraint of the one point function is obtained by using the crossing symmetry of the two point function. There are many solutions of the constraint and we can choose one of them by considering the modular bootstrap. ∗ E-mail: [email protected]

We investigate the unsupervised detection of semi-fixed cue phrases such as “This paper proposes a novel approach. . . 1” from unseen text, on the basis of only a handful of seed cue phrases with the desired semantics. The problem, in contrast to bootstrapping approaches for Question Answering and Information Extraction, is that it is hard to find a constraining context for occurrences of semi-...

Clinicians could model the brain injury of a patient through his brain activity. However, how this model is defined and how it changes when the patient is recovering are questions yet unanswered. In this paper, the use of MedVir framework is proposed with the aim of answering these questions. Based on complex data mining techniques, this provides not only the differentiation between TBI patient...

The difficulty of emergence is not the complexity but the recursivity of its working. That is why there are so many debates to know whether structure generates strategy or strategy generates structure. In fact all we know is that networking allows conversations and that conversations help creating structure, that is a system embedding procedures and technologies; in other words, the network is ...

Electronic identity (eID) cards are deployed in an increasing number of countries. These cards often provide digital authentication and digital signature capabilities, but have at the same time serious privacy shortcomings. We can expect that ordering and issuing tickets for events (e.g. soccer matches) will be increasingly done using eID cards, hence, severely threatening the user’s privacy. T...

Presently, conditions ensuring the validity of bootstrap methods for the sample mean of (possibly heterogeneous) near epoch dependent (NED) functions of mixing processes are unknown. Here we establish the validity of the bootstrap in this context, extending the applicability of bootstrap methods to a class of processes broadly relevant for applications in economics and Þnance. Our results apply...

We present a monolithic low-power, low-noise analog front-end electroencephalogram acquisition system. It draws only 500 A from a standard 9-V battery, making it suitable for use in portable systems. Although fabricated in a standard CMOS technology, by using current feedback techniques it achieves a common mode rejection ratio of 100 dB while the total input noise referred to input is kept bel...
