We build a system for the automatic detection of topic boundaries in meeting recordings. We extract a number of prosodic and lexical features from a single tabletop microphone and the human-generated transcript. We use a support vector machine trained on these features to learn the properties of topic boundaries. In a detection experiment, we see results with up to 98% correct accept rate with ...

Intrusion detection systems (IDSs) have become a necessary component of computers and information security framework. IDSs commonly deal with a large amount of data traffic and these data may contain redundant and unimportant features. Choosing the best quality of features that represent all of the data and exclude the redundant features is a crucial topic in IDSs. In this paper, a new combinat...

A seizure prediction method is proposed by extracting global features using phase correlation between adjacent epochs for detecting relative changes and local features using fluctuation/ deviation within an epoch for determining fine changes of different EEG signals. A classifier and a regularization technique are applied for the reduction of false alarms and improvement of the overall predicti...

An efficient statistical algorithm of automatic extracting road from SAR images is devised in this paper. First, an feature detecting operator is used to find the road candidate. Then another smaller operator which calculating the homogenous statistic of locate region is applied to reduce the false alarm and smooth the road edge. Finally, the road linear features are extracted by fusing the res...

Most of the car accidents were cause by improper driving behavior, according to investigates shown that changing lanes improperly would be the one of the main cause. It directed to drivers need an assisting alarm system to help them avoid the dangerous of overtaking. And, we found the existing alarm system and researches try to use different sensory outputs as the alarm signals. However, there ...

Numerous Intrusion Detection Systems (IDSs) have been developed for MANETs; however, comparatively little research focuses on intrusion alarm exchange and validation in Mobile Ad Hoc Networks (MANETs). We provide a secure alarm exchange framework for proactive MANET routing protocols and use Optimized Link State Routing model (OLSR) for the implementation. In our solution, alarms can be aggrega...

Many researchers are being involved in fire detection using camera images as information data. However earlier researches have not paid attention to the determination of the type of fire (naked or smoldering). This paper proposes an improved fire detection method based on the image features that are taken as a feed to a rough set information system (RSIS) in order to not only determine the type...

It is a well-known problem that intrusion detection systems overload their human operators by triggering thousands of alarms per day. As a matter of fact, we have been asked by one of our service divisions to help them deal with this problem. This paper presents the results of our research, validated thanks to a large set of operational data. We show that alarms should be managed by identifying...
