Further Applications of Sector-Based Detection and Short-Term Clustering
, 2006
"... This paper presents an effective implementation of detection-localization of multiple speech sources with microphone arrays. In particular, the Scaled Conjugate Gradient descent is used for fast and precise localization, within a pre-detected volume of space, and a close to realtime implementation ..."

in the short term – and acoustic speaker information, i.e. MFCCs – useful in the longer term. A dramatic improvement in speaker clustering results is obtained by the combined approach, as compared with the acoustic-alone approach, and results are close to those obtained with close-talking microphones. Finally
Short-Term Spatio-Temporal Clustering of
, 2004
"... Abstract. Accurate detection and segmentation of spontaneous multi-party speech is crucial for a variety of applications, including speech acquisition and recognition, as well as higher-level event recognition. However, the highly sporadic nature of spontaneous speech makes this task diÆcult. Moreov ..."

Moreover, multi-party speech contains many overlaps. We propose to attack this problem as a multitarget tracking task, using location cues only. In order to best deal with high sporadicity, we propose a novel, generic, short-term clustering algorithm that can track multiple objects for a low computational
Short-Term Spatio–Temporal Clustering Applied to Multiple Moving Speakers
"... Abstract—Distant microphones permit to process spontaneous multiparty speech with very little constraints on speakers, as opposed to close-talking microphones. Minimizing the constraints on speakers permits a large diversity of applications, including meeting summarization and browsing, surveillance ..."

to determine the trajectories of multiple moving speakers in the short-term only, i.e., only while they speak. Instantaneous location estimates that are close in space and time are grouped into “short-term clusters ” in a principled manner. Each short-term cluster determines the precise start and end times
Tabu Search -- Part I
, 1989
"... This paper presents the fundamental principles underlying tabu search as a strategy for combinatorial optimization problems. Tabu search has achieved impressive practical successes in applications ranging from scheduling and computer channel balancing to cluster analysis and space planning, and more ..."

Part I of this study indicates the basic principles, ranging from the short-term memory process at the core of the search to the intermediate and long

High performance messaging on workstations: Illinois Fast Messages (FM) for Myrinet
- In Supercomputing
, 1995
"... In most computer systems, software overhead dominates the cost of messaging, reducing delivered performance, especially for short messages. Efficient software messaging layers are needed to deliver the hardware performance to the application level and to support tightly-coupled workstation clusters. ..."

Attention gating in short-term visual memory
- Psychological Review
, 1986
"... Subjects first detected a target embedded in a stream of letters presented at the left of fixation and then, as quickly as possible, shifted their attention to a stream of numerals at the right of fixation. They attempted to report, in order, the four earliest occurring numerals after the target. Nu ..."

For all subjects, targets, and numeral rates, the relative position of numerals in the response sequence showed clustering, disorder, and folding. Reported numerals tended to cluster around a stimulus position 400 ms after the target
MULTIPLE CONCURRENT SPEAKER SHORT-TERM TRACKING USING A KALMAN FILTER BANK
"... This paper presents a novel filtering approach for tracking multiple concurrent speakers with a microphone array. In this framework, a Kalman filter bank that evolves in time according to a temporal Hidden Markov Model (HMM) is proposed. This approach was de-signed to overcome two major problems tha ..."

Experiments on the AV16.3 showed an average tracking rate improvement of 8 % com-pared to a short-term clustering approach
Predicting Short-Term Currency Trends
"... Abstract Currency economists are puzzled by the relatively high frequency of massive, abrupt exchange-rate changes, such as dollar-yen's 11 percent decline on October 7, 1998. This paper provides evidence that such moves may be partly caused by stop-loss orders, which create rapid, self-reinfo ..."
