چکیده

Light-rail systems are becoming more popular in cities and urban residential areas around the country. One of the main environmental impacts from light-rail systems is noise from the trains as they pass through residential areas. In response to increasing noise complaints, it is becoming more common to perform noise measurements in the residential areas and attempt to identify noise mitigation solutions based on the results. Currently, most of the noise measurements are attended with a technician keeping a log of when trains pass the measurement location so those train events can be extracted from the continuous recording during post-processing. This method limits the amount of data that can be collected due to limited man hours. A machine learning algorithm that identifies train events in a continuous noise recording would increase efficiency during both data collection and post-processing.

Laughter detection using ALISP-based N-Gram models

Laughter is a very complex behavior that communicates a wide range of messages with different meanings. It is highly dependent on social and interpersonal attributes. Most of the previous works (e.g. [1, 2]) on automatic laughter detection from audio uses frame-level acoustic features as parameters to train their machine learning techniques, such as Gaussian Mixture Models (GMMs), Support Vecto...

Using machine learning to detect events in eye-tracking data.

Event detection is a challenging stage in eye movement data analysis. A major drawback of current event detection methods is that parameters have to be adjusted based on eye movement data quality. Here we show that a fully automated classification of raw gaze samples as belonging to fixations, saccades, or other oculomotor events can be achieved using a machine-learning approach. Any already ma...

Event detection in Twitter: A machine-learning approach based on term pivoting

The large number of messages on Twitter posted each day provide rich insights into real-world events and public opinion. However, it is difficult to automatically distinguish tweets referring to such events from everyday chatter, and subsequently to distinguish significant events affecting many people from insignificant events. We apply a term-pivot approach to event detection from the Twitter ...

A Novel Approach to Event Duration Prediction

1. Abstract Durations of Events, play a pivotal role in temporal reasoning problems. Accurate estimates of time periods of events can help us obtain better solutions for several time related tasks such as sequencing events and identifying temporal relations between them. In this paper we explore the application of supervised and unsupervised machine learning techniques to predict coarse-grained...

Recognition of Visual Events using Spatio-Temporal Information of the Video Signal

Recognition of visual events as a video analysis task has become popular in machine learning community. While the traditional approaches for detection of video events have been used for a long time, the recently evolved deep learning based methods have revolutionized this area. They have enabled event recognition systems to achieve detection rates which were not reachable by traditional approac...
