This book was released on 2011-10-16 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Machine learning builds models of the world using training data from the application domain and prior knowledge about the problem. The models are later applied to future data in order to estimate the current state of the world. An implied assumption is that the future is stochastically similar to the past. The approach fails when the system encounters situations that are not anticipated from the past experience. In contrast, successful natural organisms identify new unanticipated stimuli and situations and frequently generate appropriate responses. The observation described above lead to the initiation of the DIRAC EC project in 2006. In 2010 a workshop was held, aimed to bring together researchers and students from different disciplines in order to present and discuss new approaches for identifying and reacting to unexpected events in information-rich environments. This book includes a summary of the achievements of the DIRAC project in chapter 1, and a collection of the papers presented in this workshop in the remaining parts.

Book Synopsis Modeling Audio and Visual Cues for Real-world Event Detection by : Xiaodan Zhuang
Download or read book Modeling Audio and Visual Cues for Real-world Event Detection written by Xiaodan Zhuang and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Audio-visual event detection aims to identify semantically defined events that reveal human activities. Most previous literature focused on restricted highlight events, and depended on highly ad-hoc detectors for these events. This research emphasizes generalizable robust modeling of single-microphone audio cues and/or single-camera visual cues for the detection of real-world events, requiring no expensive annotation other than the known timestamps of the training events. To model the audio cues for event detection, we leverage statistical models proven effective in speech recognition. First, a tandem connectionist-HMM approach combines the sequence modeling capabilities of the hidden Markov model (HMM) with the context-dependent discriminative capabilities of an artificial neural network. Second, an SVM-GMM-supervector approach uses noise-robust kernels to approximate the KL divergence between feature distributions in different audio segments. The proposed methods outperform our top-ranked HMM-based acoustic event detection system in the CLEAR 2007 Evaluation, which detects twelve general meeting room events such as keyboard typing, cough and chair moving. To model the visual cues, we propose the Gaussianized vector representation, constructed by adapting a set of Gaussian mixtures according to the set of patch-based descriptors in an image or video clip, regularized by the global Gaussian mixture model. The innovative visual modeling approach establishes unsupervised correspondence between local descriptors in different images or video clips, and achieves outstanding performance in a video event categorization task on ten LSCOM-defined events in the Trecvid broadcast news data, such as exiting car, running and people marching. Following an efficient branch-and-bound search scheme, we further propose an object localization approach for the Gaussianized vector representation. We jointly model audio and visual cues for improved event detection using multi-stream HMMs and coupled HMMs (CHMM). Spatial pyramid histograms based on the optical flow are proposed as a generalizable visual representation that does not require training on labeled video data. In a multimedia meeting room non-speech event detection task, the proposed methods outperform previously reported systems leveraging ad-hoc visual object detectors and sound localization information obtained from multiple microphones.

Book Synopsis Audio and Audiovisual Cueing in Visual Search by : Hugo Bertolotti

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This study attempted to resolve the findings within Vu et al. and Bertolotti and Strybel regarding horizontal and vertical auditory cue displacement on target identification by examining local target area visual saliency and target uncertainty. Targets were identified with either an auditory cue or auditory-visual cue. Auditory cues were noise bursts spatially coincident with, or directionally displaced 40 or 80 from the target. Visual cues (circle: 6.50 radius) accurately identified the local target area surrounding the target. Target uncertainty varied the percentage of targets present within a given session. For auditory cues, as target probability increased, horizontal auditory cue displacement became a greater detriment to target identification regardless of error magnitude. For auditory-visual cues, while both target present and absent search times decreased significantly compared to auditory cues, target absent identification demonstrated the most significant improvement from increasing local target area visual saliency. Design recommendations and future research are discussed.
Book Synopsis Probing auditory scene analysis by : Elyse S Sussman
Download or read book Probing auditory scene analysis written by Elyse S Sussman and published by Frontiers E-books. This book was released on 2015-02-11 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: In natural environments, the auditory system is typically confronted with a mixture of sounds originating from different sound sources. As sounds spread over time, the auditory system has to continuously decompose competing sounds into distinct meaningful auditory objects or “auditory streams” referring to certain sound sources. This decomposition work, which was termed by Albert Bregman as “Auditory scene analysis” (ASA), involves two kinds of grouping to be done. Grouping based on simultaneous cues, such as harmonicity and on sequential cues, such as similarity in acoustic features over time. Understanding how the brain solves these tasks is a fundamental challenge facing auditory scientist. In recent years, the topic of ASA was broadly investigated in different fields of auditory research, including a wide range of methods, studies in different species, and modeling. Despite the advance in understanding ASA, it still proves to be a major challenge for auditory research. This includes verifying whether experimental findings are transferable to more realistic auditory scenes. A central approach in understanding ASA is the use of certain stimulus parameters that produce an ambiguous percept. The advantage of such an approach is that different perceptual organizations can be studied without varying physical stimulus parameters. Additionally, the perception of ambiguous stimuli can be volitionally controlled by intention or task. By using this one can mirror real hearing situations where listeners intent to identify and to localize auditory sources. Recently it was also found that in classical auditory streaming sequences perceptual ambiguity was not restricted to but was observed over a broad range of stimulus parameters. The proposed Research Topic pursues to bring together scientist in the different fields of auditory research whose work addresses the issue of perceptual ambiguity. Researchers were welcome to contribute experimental reports, computational modeling, and reviews that consider auditory ambiguity in its modality specific characteristics as well as in comparison to visual ambiguous figures. The overall goal of contributions was to consider the experimental findings from the perspective of real auditory scenes. In a broader sense, the Research Topic was open for contributions which are related to the issue of active listening in complex scenes.

Book Synopsis Hearing Loss by : National Research Council
Download or read book Hearing Loss written by National Research Council and published by National Academies Press. This book was released on 2004-12-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.
