ANGUS: Real-time manipulation of vocal roughness for emotional speech transformations

Authors: Marco Liuni, Luc Ardaillon, Louise Bonal, Lou Seropian, Jean-Julien Aucouturier

arXiv

Vocal arousal, the non-linear acoustic features taken on by human and animal vocalizations when highly aroused, has an important communicative function because it signals aversive states such as fear,...

Advantages of biologically-inspired adaptive neural activation in RNNs during learning

Authors: Victor Geadah, Giancarlo Kerg, Stefan Horoi, Guy Wolf, Guillaume Lajoie

arXiv

Dynamic adaptation in single-neuron response plays a fundamental role in neural coding in biological neural networks. Yet, most neural activation functions used in artificial networks are fixed and mo...

A Connectome Based Hexagonal Lattice Convolutional Network Model of the Drosophila Visual System

Authors: Fabian David Tschopp, Michael B. Reiser, Srinivas C. Turaga

arXiv

What can we learn from a connectome? We constructed a simplified model of the first two stages of the fly visual system, the lamina and medulla. The resulting hexagonal lattice convolutional network w...

How effective is your blinding?

Authors: Anil Gore, Sharayu Paranjpe

arXiv

This report answers queries about extending the blinding index approach to a situation with measurements at multiple time points. The key question is how to test if there is progressive unblinding. A...

Electronic schematic for bio-plausible dopamine neuromodulation of eSTDP and iSTDP

Authors: Max Talanov, Yuriy Gerasimov, Victor Erokhin

arXiv

In this technical report we present novel results of the dopamine bio-plausible neuromodulation excitatory (eSTDP) and inhibitory (iSTDP) learning. We present the principal schematic for the neuromodu...

Revisiting the effect of spatial resolution on information content based on classification results

Authors: M. G. Palacio, S. B. Ferrero, A. C. Frery

arXiv

Polarimetric Synthetic Aperture Radar (PolSAR) images are an important source of information. Speckle noise gives SAR images a granular appearance that makes interpretation and analysis hard tasks. A...

Vanadium dioxide circuits emulate neurological disorders

Authors: J. Lin, S. Guha, S. Ramanathan

arXiv

Information in the central nervous system (CNS) is conducted via electrical signals known as action potentials and is encoded in time. Several neurological disorders including depression, Attention De...

Bayesian Model Selection for a Class of Spatially-Explicit Capture Recapture Models

Authors: Soumen Dey, Mohan Delampady, Arjun M. Gopalaswamy

arXiv

A vast amount of ecological knowledge generated recently has hinged upon the ability of model selection methods to discriminate among various ecological hypotheses. The last decade has seen the rise o...

Applications of robust estimators of covariance in examination of inter-laboratory study data

Authors: Stephen L R Ellison

arXiv

This paper illustrates the use of selected robust estimators of covariance or correlation in the identification of anomalous laboratory results in inter-laboratory data. It is shown that robust estima...

Modeling data with zero inflation and overdispersion using GAMLSSs

Authors: Gustavo Thomas, Luiz R. Nakamura, Rafael A. Moral, Clarice G. B. Demétrio

arXiv

Count data with high frequencies of zeros are found in many areas, specially in biology. Statistical models to analyze such data started to be developed in the 80s and are still a topic of active rese...

Compatible Matrices of Spearman's Rank Correlation

Authors: Bin Wang, Ruodu Wang, Yuming Wang

arXiv

In this paper, we provide a negative answer to a long-standing open problem on the compatibility of Spearman's rho matrices. Following an equivalence of Spearman's rho matrices and linear correlation...

A New Nonparametric Estimate of the Risk-Neutral Density with Applications to Variance Swaps

Authors: Liyuan Jiang, Shuang Zhou, Keren Li, Fangfang Wang, Jie Yang

arXiv

We develop a new nonparametric approach for estimating the risk-neutral density of asset prices and reformulate its estimation into a double-constrained optimization problem. We evaluate our approach...
