Deep fadings occurred as a result of multipath propagation because some sub carriers that loses its information as well as fading in a non-recoverable degree, and consequently results in a poorer system performance. Since the training speed of LMS algorithm used in estimation of channel coefficients in time domain for OFDM based systems is not generally sufficient to achieve the desired performance levels in training time defined by standards, a fuzzy logic based algorithm is adapted to get a faster performance. An application of fuzzy logic based high performance LMS algorithm for OFDM systems is investigated in this paper. The aim of the proposed method is to produce the required fuzzy rule base and fuzzy subsets for fuzzy logic controller in order to speed up the LMS algorithm. The generations of fuzzy rules are based on the comparison of estimated signal by equalizer or channel output. The obtained results of simulations show that the LMS algorithm based on fuzzy logic (F-LMS) increases the performance in OFDM systems significantly and converges to the performance of the RLS algorithm","PeriodicalId":415037,"journal":{"name":"2006 IEEE 14th Signal Processing and Communications Applications","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127716271","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}

Similar to translation from one language to another, this approach considers the object recognition problem as the translation of visual elements to words. The visual elements represented in feature space are first categorized into a finite set of blobs. Then, the correspondences between the blobs and the words are learned using a method adapted from statistical machine translation. Finally, the correspondences, in the form of a probability table, are used to predict words for particular image regions (region naming), for entire images (auto-annotation), or to associate the automatically generated speech transcript text with the correct video frames (video alignment). Experimental results are presented on TRECVID 2004 data set, which consists of about 150 hours of news videos associated with manual annotations and speech transcript text.","PeriodicalId":415037,"journal":{"name":"2006 IEEE 14th Signal Processing and Communications Applications","volume":"462 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131796204","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}

When the goal is set as a big reward, the optimal path is found as soon as the reward accumulated reaches its highest value. Upon modification of the start and goal points, the information concerning how to reach the goal becomes useless even if the environment does not change. In this study, Q-learning is improved by making the usage of the past data possible. To achieve this, action probabilities for certain start and goal points are found and a neural network is trained with those values to estimate the action probabilities for other start and goal points. A radial basis function network is used as neural network for it can support local representation and can learn fast when there is a few number of inputs.
