Although such a classifier was proposed for face recognition, it has been proposed in medical diagnosis from ultrasonic images in this work for the first time. The classifier is based on ℓ1-norm based sparse representation of a patient's test data in terms of linear combination of the features of the benign and malignant test lesions available in the training set. The proposed classifier introduces an index called Sparsity Rank (SR) for the classification obtained from the normalized energy of the weights as a linear combination of the global sparse representation of the ultrasound images of the training set. The performance of the classifier is further enhanced to a great extent by two ways: first, by intelligently combining the features extracted from the multiple ultrasound scan of the same mass, and the second, by using the optimal feature set obtained by a suboptimal strategy that avoids the time exhaustive brute force approach that has a combinatorial search space. With all the enhancements an AUC of 0.9802 has been achieved, when training and testing sets are chosen by leave-one-out approach from the data set.","PeriodicalId":113626,"journal":{"name":"16th Int'l Conf.

In the first part, a PF table is constructed, while the second part deals with Bangla automatic speech recognition (ASR) using PFs. For Bangla language, fifty three phonemes including both vowels and consonants are considered in which the phones, k (/s/) and m (/s/), and, Y (/n/) and b (/n/) contain approximately same spectrum and hence, they share same PFs. In the PF table, twenty two PFs (Silence, Short Silence, Stop, ...) are required for representing all the Bangla phonemes. On the other hand, the second part comprised of three stages: i) first stage deals with acoustic features, mel frequency cepstral coefficients (MFCCs) extraction, ii) second stage embeds PFs extraction procedure using a multilayer neural network (MLN) and iii) the final stage integrates a triphone-based hidden Markov model (HMM) for generating the output text strings by inputting log values of twenty two dimensional PFs. In the experiments on Bangla Newspaper Article Sentences, it is observed that the PF-based ASR system provides higher word correct rate, word accuracy and sentence correct rate in comparison with the standard MFCC-based method.","PeriodicalId":113626,"journal":{"name":"16th Int'l Conf.

In this paper, a method is proposed to generate poster based on color feature and relevance feedback. Color feature is used because it is more closely to human perception and it is easy to extract, match and also effective for indexing. In our method as color feature of a frame in a video, HSV color space and Color Moment are used. To calculate similar frames i.e. to detect shot, Euclidean distance between the features of frames are compared with a predefined threshold value. One frame is selected from each shot and stored with Temporally Occurrence Value (TOV) of the Frame. As a video can have similar shots in it but in different times, so the similar frames from the similar shots of different times are detected and one frame is selected from them. Then this selected frame is stored with Permanent Occurrence Value (POV) of the Frame by replacing its TOV and discarding others of them from storage. Finally, five frames with maximum POV are selected to generate poster layout and ranked the posters by their relevance feedback. The experiments show the robust result than existing methods.","PeriodicalId":113626,"journal":{"name":"16th Int'l Conf.

Due to continuous device scaling, NBTI effect has become more severe than before and affected device life-time. Memory devices like SRAMs are tremendously affected by NBTI as the PMOS transistor gate is connected at `0' logic for a long time. Several device-level and architecture-level solutions have been proposed to improve device life-time by interrupting NBTI degradation. Such an architectural level solution is to flip data in a particular SRAM cell after a certain time, causing periodic stress and relaxation. SRAM data flipping techniques proposed so far are not so time friendly as it is needed to access each memory cell individually and flip the data stored. It makes the process more time consuming and inconvenient for present ultra-fast system with high activity factor. In this paper, we proposed a new 7-T SRAM cell to allow flipping data of more than one memory cells at same clock pulse, hence decreasing the flipping time of entire memory array and concluded that with the new proposed cell and flipping procedure, data flipping of the entire memory array will become much faster which will ensure convenient NBTI recovery.","PeriodicalId":113626,"journal":{"name":"16th Int'l Conf.
