This structure has improved the latency and energy consumption in the cloud. In this heterogeneous and distributed environment, resource allocation is very important. Hence, scheduling will be a challenge to increase productivity and allocate resources appropriately to the tasks. Programs that run in this environment should be protected from intruders. We consider three parameters as authentication, integrity, and confidentiality to maintain security in fog devices. These parameters have time and computational overhead. In the proposed approach, we schedule the modules for the run in fog devices by heuristic algorithms based on data mining technique. The objective function is included CPU utilization, bandwidth, and security overhead. We compare the proposed algorithm with several heuristic algorithms. The results show that our proposed algorithm improved the average energy consumption of 63.27%, cost 44.71% relative to the PSO, ACO, SA algorithms.","PeriodicalId":380266,"journal":{"name":"2017 3rd Iranian Conference on Intelligent Systems and Signal Processing (ICSPIS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116186212","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 propose to consider Mel sub-band speech processing in denoising auto-encoder(DAE) training to benefit from both mentioned method properties. In this way, in the training process, we assign lower weights to the Mel subbands containing higher level of noise, while we assign higher weights to sub-bands including lower level of noise. Furthermore, we use restricted Boltzmann Machine for pre-training of DAE. Thus, DAE can train the noise behavior and performs better in noise reduction. Experimental results on Aorura2 database, show the proposed DAE improve performance of logarithm of Mel filter bank energies (LMFB) for noisy speech recognition about 47.8% in the best case.","PeriodicalId":380266,"journal":{"name":"2017 3rd Iranian Conference on Intelligent Systems and Signal Processing (ICSPIS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115516567","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, a content-based movie recommender system is proposed that captures the temporal user preferences in user modeling and predicts the preferred movies. The proposed method provides a user-centered framework that incorporates the content attributes of rated movies (for each user) into a Dirichlet Process Mixture Model to infer user preferences and provide a proper recommendation list. We implement the proposed method and use the MovieLens dataset to perform experiments.

The HMAX is an effective object recognition method which is inspired by mammalian visual systems. Despite achieving a relatively good classification rate, this model needs many computing resources and a rather high volume of temporary memory during its process. High computational load and low processing speed is a big challenge in this algorithm. Due to randomly feature extraction, many redundant features might be extracted which causes an extremely increment in calculations and processing time. To tackle this problem, a feature selection strategy based on filter method is added to the standard HMAX. By eliminating redundant and selecting distinctive features, the new proposed HMAX achieves the same accuracy rate as the previous HMAX resulted whereas it is faster more than three times than the standard HMAX. Suggested approach plays an elegant role in processing speed, especially when the number of extracted features is relatively high. The standard HMAX and the proposed one are evaluated on the Caltech5 dataset. The experiments show that the proposed manner reaches the same accuracy rate as the standard HMAX, even though near 79% of the extracted patches were removed. Although feature selection stage imposes a little computational load on the algorithm, it provides us to accelerate process up to 3.3X times higher than the speed of standard HMAX. This method is very suitable for implementation especially on limited resources such as FPGA platform and DSP processors.","PeriodicalId":380266,"journal":{"name":"2017 3rd Iranian Conference on Intelligent Systems and Signal Processing (ICSPIS)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134426724","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}

Content based image retrieval (CBIR) is a kind of search that selects examples from an image set that have a similar content to an input query image. Each CBIR system consists of two substantial factors, feature extraction and similarity measure. Based on the type of these parts, many CBIR systems are proposed. In this paper we present not only how to design a CBIR system for MRI brain Tumor images, but also a comparison between the different implemented CBIR systems and ours. Furthermore, in this research, using a DML (Distance Metric Learning) instead of the rigid distance metric such as Euclidean distance as the Similarity measure has helped the researchers to obtain a better mAP (mean Average Precision) as the result. The experimental results of our CBIR system show that it has a better performance than other rivals in the field. The obtained mean average precision of our CBIR system is 92.41 that is significant in MRI brain tumor.","PeriodicalId":380266,"journal":{"name":"2017 3rd Iranian Conference on Intelligent Systems and Signal Processing (ICSPIS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129864828","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 the previous researches, it is shown that the power spectral flatness measure (PSFM) value implies which statistical model fits the best to the Discrete Cosine Transform (DCT) coefficients of noisy speech. We utilize the similar trend to evaluate the relation between the real/imaginary valued DFT coefficients of noisy speech in different stationary and non-stationary noise signals and SNRs. In the conducted experiments, the Kolmogorov-Smirnov (KS) test is employed to quantify the Goodness-of-Fit (GOF) of each parametric statistical model, which is Gaussian, Gamma and Laplacian probability density functions (PDFs). The likelihood ratio (LR) concluded from the selected statistical model is employed to calculate the smoothed LR (SLR) and multiple observation LR (MOLR). The final decision is made by utilizing Dempster-Shafer Theory (DST) to combine the three LR tests that are basic LRT, MO-LRT and SLRT. The usage of the proposed VAD is developed for non-stationary noise signals employing Gerkmann's noise power spectral density estimator. The experiments demonstrate that our proposed method outperforms the conventional VADs in various adverse conditions.","PeriodicalId":380266,"journal":{"name":"2017 3rd Iranian Conference on Intelligent Systems and Signal Processing (ICSPIS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133075108","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}
