Ensemble coding of average length and average orientation are correlated
Vision Research, 2021Viewers can summarize redundant features in groups of objects into an ensemble percept. There appears to be separate mechanisms underlying ensemble perception of low- and high-level visual features, but it is unclear whether ensemble perception of different low-level features is supported by common mechanisms.

Anomaly Detection Ensembles: In Defense of the Average
2015 IEEE/WIC/ACM International Conference on Web Intelligence and Intelligent Agent Technology (WI-IAT), 2015When given multiple models it is often useful to combine them for improved reliability or performance over the individual models. Over the years many outlier metrics and detection methods have been developed for the purposed of finding data incongruous with the rest of the data.

Ensemble average TIRM for imaging amperometry
Journal of Colloid and Interface Science, 2013Colloidal particles can function as probes of local electrochemical current density if a functional relationship between the response of the particles and the electric field in the vicinity of the particles can be established. The nanometer scale movement of a single colloidal particle during cyclic voltammetry can be observed with the aid of total ...

Averaging over many predictors leads to a reduction of the variance portion of the error. We present a method for evaluating the mean squared error of an infinite ensemble of predictors from finite (small size) ensemble information. We demonstrate it on ensembles of networks with different initial choices of synaptic weights.

An Evaluation of the Ensemble Averaged Impedance Cardiogram
Psychophysiology, 1990ABSTRACTThe ensemble averaged impedance cardiogram was evaluated during rest and during vocal mental arithmetic stress in samples of female (n=17) and male (n=40) undergraduates. Measures of myocardial performance determined from ensemble averaged signals were compared to those determined by simple beat‐to‐beat averaging over 60‐s and 20‐s sampling ...

Ensemble averaging of mass values
Atomic Data and Nuclear Data Tables, 1976Abstract An ensemble of mass tables is generated by extrapolating with the transverse Garvey-Kelson equation from different subsets of experimentally known masses. Predictions of unknown masses are obtained by averaging over the ensemble. The averaging procedure also yields the uncertainties accompanying these predictions.

The chimical potential as an ensemble average
Physics Letters A, 1982Abstract We show that the chemical potential of a fluid is related to the canonical ensemble average of exp{ ψ kT } where ψ is the energy of interaction between one particle and the others. A similar result holds for the case of a lattice gas model in an ensemble where the number of occupied sites is kept fixed.

Ensemble averages and molecular symmetry
Molecular Physics, 1988It is shown that a simple assumption enables ensemble average tensor components, including time correlation functions, on molecular or laboratory axes, to be identified as zero or else as potentially non-zero. The tensors may refer to any properties and are illustrated predominantly by linear and angular velocities and their products. The assumption is

Ensemble Average, Turbulence Closure
1985Publisher Summary The word “turbulence” is reserved for small-scale, three-dimensional motions that are random but whose ensemble average properties are approximately deterministic in the sense that they are related, either through laboratory measurements or through closure models, to the mean velocity and density gradients.
