This paper presents the results of psychophysical experiments dealing with pitch-marker positioning within the Pitch Synchronous OverLap and Add (PSOLA) framework. Sustained natural vowels were PSOLAmodified in fundamental frequency. The experiments were aimed at determining the auditory sensitivity to (1) deterministic shifts of either all or single pitch markers within a sequence, and (2) ran...

(ARQ) link layer protocols for wireless connections. However, a drawback comes with their use when transferring mixed traffic type, which is the introduction of excessive and highly jittered transmission delay, which negatively affect the performance of both real-time and TCP traffic. Here, we propose a selective ARQ protocol which is capable of switching between ARQ and non-ARQ modes based on ...

A particular backpropagation network, called a network of value units, was trained to detect problem type and validity of a set of logic problems. This network differs from standard networks in using a Gaussian activation function. After training was successfully completed, jittered density plots were computed for each hidden unit, and used to represent the distribution of activations produced ...

A common practice to gain invariant features in object recognition models is to aggregate multiple low-level features over a small neighborhood. However, the differences between those models makes a comparison of the properties of different aggregation functions hard. Our aim is to gain insight into different functions by directly comparing them on a fixed architecture for several common object...

This paper is concerned with a robust estimator of the intensity of a stationary spatial point process. The estimator corresponds to the median of a jittered sample of the number of points, computed from a tessellation of the observation domain. We show that this median-based estimator satisfies a Bahadur representation from which we deduce its consistency and asymptotic normality under mild as...

We propose several fast (quasi real-time) methods to dejitter digital video images in one step. They are based on an essential disproportion of the magnitude of the second-order vertical differences along the columns of a real-world image and all its jittered versions. These methods need one iteration to dejitter the image, which involves a number of steps equal to the number of its rows. They ...

We have shown in previous work that the perception of order in point patterns is consistent with an interval scale structure (Protonotarios, Baum, Johnston, Hunter, & Griffin, 2014). The psychophysical scaling method used relies on the confusion between stimuli with similar levels of order, and the resulting discrimination scale is expressed in just-noticeable differences (jnds). As with other ...

We are given a neural spike train with spike times t1, . . . , tn and we want to discover something about the resolution over which these spike times were generated. A heuristic approach is to fix a statistic of the spike train, say f(t1, . . . , tn), and then Monte Carlo jitter each of the spike times by some small random amount, computing the statistic over and over again for each jitter. Pre...
