Perceptron based predictors are highly accurate. This high accuracy is the result of exploiting long history lengths [1] and is achieved at the expense of high complexity. The dot product of two vectors is used as prediction. The first vector is the branch outcome history where the second vector is composed of per branch weights, which represent the correlation between branch outcome and previo...

This study was inspired by VanPatten and Uludag’s (2011) study on the transferability of training via processing instruction to output tasks and Mori’s (2002) work on the development of talk-in-interaction during a group task. An interview was devised as the pretest, posttest, and delayed posttest to compare four intervention types for teaching the simple past passive: traditional intervention ...

This paper describes real user assessment of NativeAccent, a pronunciation tutor using automatic speech recognition that is a commercial product. It describes the product and discusses the issues involved in assessments of real users in real situations, such as assessments based on the customer’s own criteria instead of more academic measures, and the variations in the customers’ measures. Resu...

English language teaching (ELT) writing practitioners have long attempted to improve EFL/ESL learners’ competence in writing with recourse to either instruction or feedback. Likewise, researchers have, to date, mainly focused on either of these treatments to enhance language learners’ composing ability. Which treatment leads to more significant improvements is, however, unclear. Moreover, of th...

This study investigated the effects of planned focus-on-form instruction (pFFI) on developing oral grammatical accuracy in Iranian English EFL learners. To this end, 60 lower-intermediate EFL learners studying English in a private English language institute in Tehran, Iran, were randomly assigned to two classes. Both classes received a task-based instruction on grammatical points elicited in or...

The Karatsuba multiplication algorithm is an algorithm for computing the product of two natural numbers represented in the binary number system. This means that the algorithm actually computes a function on bit strings. The restriction of this function to bit strings of any given length can be computed according to the Karatsuba multiplication algorithm by a finite instruction sequence that con...
