We analyze the convergence rate of a first-order method applied on a smooth, strictly convex, and parametric upper bound on the LASSO objective function. The upper bound approaches the true non-smooth objective as the parameter tends to infinity. We show that a gradient-based algorithm, applied to minimize the smooth upper bound, yields a convergence rate of O (1/K), where K denotes the number of iterations performed. The analysis also reveals the optimum value of the parameter that achieves a desired prediction accuracy, provided that the total number of iterations is decided a priori. The convergence rate of the proposed algorithm and the amount of computation required in each iteration are same as that of the iterative soft thresholding technique. However, the proposed algorithm does not involve any thresholding operation. The performance of the proposed technique, referred to as smoothed LASSO, is validated on synthesized signals. We also deploy smoothed LASSO for estimating an image from its blurred and noisy measurement, and compare the performance with the fast iterative shrinkage thresholding algorithm for a fixed run-time budget, in terms of the reconstruction peak signal-to-noise ratio and structural similarity index.","PeriodicalId":279637,"journal":{"name":"2016 Twenty Second National Conference on Communication (NCC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126892961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These non-verbal speech sounds may possibly communicate some emotion, gesture or physiological condition of a human being. Cough sounds mostly indicate symptoms of a disease and are used sometimes as a gesture to draw attention. Analysing cough sounds using speech signal processing methods can be useful for assisting the medical experts in ailment diagnosis, and also for making machines more intelligent and human-like. This paper describes a database collected for cough speech sounds, named as IIIT-S CSSD. The database consists of three categories, namely, ailment cough, simulated cough and normal speech. Normal speech is recorded for each speaker, as a reference. Spectrograms are used as ground truth reference for preliminary analysis. This database can be helpful in analysing further the differences in cough sounds of different categories such as dry and wet cough, involuntary and voluntary cough, ailment and simulated cough, or age-wise differences in cough sounds etc. Few signal processing methods and initial analysis results indicating the differences in characteristics of different cough sounds are also discussed.","PeriodicalId":279637,"journal":{"name":"2016 Twenty Second National Conference on Communication (NCC)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129127237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we analyze a variant of degradation of service attacks against TCP that makes use of forged duplicate acknowledgments in order to degrade the throughput of an on-going connection. The receipt of three (forged) duplicate acknowledgments is an indicator towards the presence of congestion on the route between the server and client. To cope up with the congestion, the server reduces the congestion window resulting in throughput reduction. As the semantics of the attack remains the same under normal and attack conditions, the signature and anomaly based Intrusion Detection System (IDS) fail to detect the throughput degradation attack. We also propose an active IDS in order to detect the attack. An active IDS is capable of injecting packets in to the network in order to create difference between normal and attack scenarios. The simulation experiments are carried out to check the validity of proposed detection scheme. The proposed scheme is light weight and can be easily deployed on existing systems.","PeriodicalId":279637,"journal":{"name":"2016 Twenty Second National Conference on Communication (NCC)","volume":"362 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115941070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
