Added modules are used for membership functions shapes optimization. Experimental results from experiments with the systems are given, some of them are improvements of earlier results.

One of the main difficulties regarding the face recognition systems is to recognize face in different views and poses. In this paper we propose a new algorithm which utilizes the combination of texture and depth information to overcome the problem of pose variation and illumination change for face recognition. In the proposed algorithm, we first use intensity image to extract efficient key features and find probable face matches in the face database using feature matching algorithm. We have defined some criteria to find the final match based on texture information or leave the decision to second stage. In the second stage the depth information are normalized and used for pose invariant face recognition. We tested the proposed algorithm using a face database with different poses and illumination and compared the results with those of other methods. We obtained the recognition rate of 88.96 percent which shows the considerable enhancement compared to previous methods.","PeriodicalId":227890,"journal":{"name":"10th Symposium on Neural Network Applications in Electrical Engineering","volume":"186 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121727137","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}

Two machine learning techniques with ability of time series prediction were analyzed: a nonlinear autoregressive neural network (NARX) and an adaptive-network-based fuzzy inference system (ANFIS). Networks were compared in terms of minimum number of sensors needed for accurate prediction, timing errors, false detections and generalization ability. ANFIS network predicted more accurately, while NARX network needed less sensors, had less false detections and better generalization.","PeriodicalId":227890,"journal":{"name":"10th Symposium on Neural Network Applications in Electrical Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130588868","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}

The algorithm combines a perceptron neural network with simple signal processing and rule-based classification. In parallel, gait was recorded with video camera.

In this paper, several ANN models were addressed to identify the future energy consumption. Each model has been constructed using different structures, learning algorithms and transfer functions in order the best generalizing ability to be achieved. Actual input and output data were used in the training, validation and testing process.

The preprocessing stage is applied for required image enhancement. Then the abdominal MRI images are partitioned to different regions using combined recursive watershed transform and neural network. The feed forward neural network is trained and used for spleen features extraction. The features extracted using neural networks are used to monitor the quality of the output of watershed transform and adjusting required parameter automatically. The process of adjusting parameters is performed sequentially in several iterations.
