Résumé

This paper proposes modifications to the Multi-resolution RASTA (MRASTA) feature extraction technique for the automatic speech recognition (ASR). By emulating asymmetries of the temporal receptive field (TRF) profiles of auditory mid-brain neurons, we obtain more than 13%13\% relative improvement in word error rate on OGI-Digits database. Experiments on TIMIT database confirm that proposed modifications are indeed useful.

Error correction code
In computing, telecommunication, information theory, and coding theory, forward error correction (FEC) or channel coding is a technique used for controlling errors in data transmission over unreliable or noisy communication channels. The central idea is that the sender encodes the message in a redundant way, most often by using an error correction code or error correcting code (ECC). The redundancy allows the receiver not only to detect errors that may occur anywhere in the message, but often to correct a limited number of errors.
Soft error
In electronics and computing, a soft error is a type of error where a signal or datum is wrong. Errors may be caused by a defect, usually understood either to be a mistake in design or construction, or a broken component. A soft error is also a signal or datum which is wrong, but is not assumed to imply such a mistake or breakage. After observing a soft error, there is no implication that the system is any less reliable than before. One cause of soft errors is single event upsets from cosmic rays.
Ingénierie des caractéristiques
L'ingénierie des caractéristiques (en anglais feature engineering) a un rôle important, notamment dans l’analyse des données. Sans données, les algorithmes d’exploitation et d’apprentissage automatique de données ne seront pas en mesure de fonctionner. En effet, il s’avère qu’en réalité, on ne pourrait réaliser que peu de choses si nous ne disposions que de très peu de caractéristiques afin de pouvoir représenter les données, ou les banques de données, sous-jacentes.

A Cache-Assisted Scratchpad Memory for Multiple-Bit-Error Correction

Hossein Asadi, Nooshin Sadat Mirzadeh

Scratchpad memory (SPM) is widely used in modern embedded processors to overcome the limitations of cache memory. The high vulnerability of SPM to soft errors, however, limits its usage in safety-critical applications. This paper proposes an efficient faul ...
