Long Short-Term Memory Recurrent neural networks (LSTM-RNNs) have been widely used for speech recognition, machine translation, scene analysis, etc. Unfortunately, general-purpose processors like CPUs and GPGPUs can not implement LSTM-RNNs efficiently due to the recurrent nature of LSTM-RNNs. FPGA-based accelerators have attracted attention of researchers because of good performance, high energy-efficiency and great flexibility. In this work, we present an FPGA-based accelerator for LSTM-RNNs that optimizes both computation performance and communication requirements. The peak performance of our accelerator achieves 7.26 GFLOP/S, which significantly outperforms previous approaches.

We consider the Gaussian interference channel as a non-cooperative game taking into account the cost of the transmission. We study the conditions of the existence of a pure Nash equilibrium. Particularly, for the many-user case we give sufficient conditions that lead to a Nash equilibrium, and for the two-user case we exhaustively describe the conditions of the existence and the uniqueness of a pure Nash equilibrium and we show the existence of best-response dynamics that converge to one of them.

We present the 30-min cadence Kepler/K2 light curve of the Type Ia supernova (SN Ia) SN 2018agk, covering approximately one week before explosion, the full rise phase and the decline until 40 days after peak. We additionally present ground-based observations in multiple bands within the same time range, including the 1-day cadence DECam observations within the first ~5 days after the first light. The Kepler early light curve is fully consistent with a single power-law rise, without evidence of any bump feature. We compare SN 2018agk with a sample of other SNe Ia without early excess flux from the literature. We find that SNe Ia without excess flux have slowly-evolving early colors in a narrow range (g - i ≈ -0.20±0.20 mag) within the first ~ 10 days. On the other hand, among SNe Ia detected with excess, SN 2017cbv and SN 2018oh tend to be bluer, while iPTF16abc's evolution is similar to normal SNe Ia without excess in g - i. We further compare the Kepler light curve of SN 2018agk with companion-interaction models, and rule out the existence of a typical non-degenerate companion undergoing Roche-lobe overflow at viewing angles smaller than 45°. © 2021, CC BY.

The use of unimodal biometric system is very low because of physiological defects, modes of user and their environment. Some of those drawbacks are alleviated by providing same identity for multiple evidences. Here a multimodal biometric system is proposed based on LBP, PCA and probabilistic neural network (PNN). In proposed method LBP extracted the Face features from face images and those features are given as input to PCA that generates Face Feature Vector with reduced Dimensions. Finger features are extracted from Fingerprint images using LBP and those features are given as input to PCA that generates Finger Feature Vector with reduced Dimensions. Using LBP, the distinct textual features of face and fingerprint are extracted. Weighted Summation Fusion method is used to combine these unimodal features. A probabilistic neural network is used as Classifier. An average recognition rate of 97.5% achieved with proposed method. Proposed method show that the proposed algorithm requires low computational cost. © 2016 IEEE.

Streaming processing is an important technology that finds applications in networking, multimedia, signal processing, etc. However, it is very challenging to design and implement streaming applications as they impose complex constraints. First, the tasks involved in the streaming applications must complete the computation under a latency constraint. Second, streaming systems are built under more and more stringent power budget. Hence, power capping technique is employed to manage the power consumption for streaming systems. To accommodate these needs, heterogeneous systems that consist of CPUs and FPGAs are becoming increasingly popular due to their performance and power benefits. In this paper, we optimize the throughput for streaming applications on CPU-FPGA heterogeneous system under latency and power constraints. We develop two algorithms to map the tasks onto the heterogeneous system and order their execution by exploiting the heterogeneity in architectural capabilities and task characteristics. We also employ pipelining to improve the throughput by overlapping the execution of different frames and use frequency scaling to adjust the execution of tasks for power saving. Experiments using a variety of streaming applications show that our heterogeneous solution can successfully meet the latency and power constraints for the cases where the CPU implementation fails. Furthermore, our technique can improve the throughput by 37.32% on average.

With the advent of more users accessing internet for information retrieval, researchers are more focused in creating system for recommendation of web service(WS) which minimize the complexity of selection process and optimize the quality of recommendation. This paper implements a framework for recommendation of personalized WS coupled with the quality optimization, using the quality features available in WS Ontology. It helps users to acquire the best recommendation by consuming the contextual information and the quality of WS. Adaptive framework performs i) the retrieval of context information ii) calculation of similarity between users preferences and WS features, similarity between preferred WS with other WS specifications iii) collaboration of web service ratings provided by current user and other users. Finally, WS quality features are considered for computing the Quality of Service. The turnout of recommendation reveals the selection of highly reliable web services, as credibility is used for QoS predication. © Springer International Publishing AG 2016.

Over the past few years there are many developments in the area of classification in data mining. Classification is a supervised learning method, that maps data into predefined groups or classes. Nowadays classification techniques are extensively used in different applications. In this area most of the research works are done on text, image, signal etc. The main goal of this paper is to use a dictionary-based approach to learn, represent and classify documents. We consider dictionary as a collection of documents and each document in the dictionary is represented as a collection of vectors. An algorithm is also implemented to easily locate a class specific document in the dictionary and if it is not present, update the dictionary. The existing method is based on a dictionary learning algorithm which only improves the document representation based on Singular Value Decomposition (SVD) updation. Since SVD will not be helpful for discrimination of data, so our proposed algorithm is Linear Discriminant Analysis (LDA) for learning a discriminating dictionary. On applying the proposed algorithm on well known dataset, the overall results obtained shows 90% improvement in accuracy. The advantage is that it can be used for both representation as well as classification. © 2016 IEEE.

There exist various web-based agriculture information systems. These systems provide the required information to farmers about different crops, soil, different farming techniques, etc. These web-based agriculture information systems deal with numerous kinds of data but they do not maintain consistency and the semantics of the data. Hence an OWL (Web Ontology Language) is used for designing required information in the web which provides meaningful annotations and vocabulary of the terms about a certain domain area to achieve the semantics for the web-based systems. Here in this paper we are building ontology of an agriculture system which is modeled in web ontology language (OWL) in protégé 5.0 framework for semantic web apps. In this paper, the usages of the famer’s or user’s aspect of various components of the e-agriculture systems are analyzed, with respect to the social web components for easy access through the semantic web. © Springer science+Business Media Singapore 2016.

A Hybrid Method of Domain Lexicon Construction for Opinion Targets Extraction Using Syntax and Semantics

引用

Journal of computer science & Technology 2016年第3期31卷 595-603页

Opinion targets extraction of Chinese microblogs plays an important role in opinion mining. There has been a significant progress in this area recently, especially the method based on conditional random field （CRF）. However, this method only takes lexicon-related features into consideration and does not excavate the implied syntactic and semantic knowledge. We propose a novel approach which incorporates domain lexicon with groups of syntactical and semantic features. The approach acquires domain lexicon through a novel way which explores syntactic and semantic information through Part- of-Speech, dependency structure, phrase structure, semantic role and semantic similarity based on word embedding. And then we combine the domain lexicon with opinion targets extracted from CRF with groups of features for opinion targets extraction. Experimental results on COAE2014 dataset show the outperformance of the approach compared with other well-known methods on the task of opinion targets extraction.
