چکیده
MIREX provides us with a framework to evaluate our music information retrieval (MIR) algorithms. It does so by running them on a previously unknown dataset and comparing the performance of different algorithms. There are many different tasks available : Music Classification, Music Similarity, Music Transcription ... In 2005, We have participated to the Onset Detection task and our algorithms [1] has been classified as first and second position for the accuracy of detection. However, it was classified as last and second last for the speed of detection. In real life applications, such a computational power requirement is unacceptable. Therefore, we did some modifications to the algorithm to greatly enhance the speed. This paper describe the new algorithm. First we give an overview of the algorithm. Next, we explain some details of the convolutional neural network (CNN) [2]. We also describe how we extract the the onset from the output of the CNN. Finally, we have a little discussion about the speed of the algorithm.

Woven Turbo Codes
A new code construction namely woven turbo codes, is presented , which is a variation of woven convolutional codes. Parallel encoders (turbo codes 2]) can be considered as a special case of woven turbo encoders, where only one outer and inner encoder is used. However, woven turbo codes with a larger number of outer codes yield higher minimum distances than turbo codes with random permutations.
متن کاملThe geometry of turbo-decoding dynamics
The spectacular performance offered by turbo codes sparked intense interest in them. A considerable amount of research has simplified, formalized, and extended the ideas inherent in the original turbo code construction. Nevertheless, the nature of the relatively simple ad hoc turbo-decoding algorithm has remained something of a mystery. We present a geometric interpretation of the turbo-decodin...
