The estimation of the watermelon density from a two-dimensional photograph [PDF]

Warasan Witthayasat Lae Theknoloyi Mahawitthayalai Mahasarakham, 2019
The density of a watermelon floating in a container of water is estimated with a simplified method from theoretical geometry without consideration of three –dimensional effects. The watermelon was approximated as a sphere.

Evaluation of Acoustic Recording Devices to Survey Northern Bobwhite Populations

Wildlife Society Bulletin, 2020
Reliable methods for monitoring wildlife populations are paramount to effective conservation and management. There are a variety of available techniques that vary in cost and feasibility. We field‐tested a commercially available acoustic recording device

Robust kernel density estimation [PDF]

2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008
We propose a method for nonparametric density estimation that exhibits robustness to contamination of the training sample. This method achieves robustness by combining a traditional kernel density estimator (KDE) with ideas from classical $M$-estimation.

Multivariate kernel density estimation with a parametric support [PDF]

Opuscula Mathematica, 2009
We consider kernel density estimation in the multivariate case, focusing on the use of some elements of parametric estimation. We present a two-step method, based on a modification of the EM algorithm and the generalized kernel density estimator, and ...

Adaptive density estimation for stationary processes [PDF]

, 2009
We propose an algorithm to estimate the common density $s$ of a stationary process $X_1,...,X_n$. We suppose that the process is either $\beta$ or $\tau$-mixing.

Unified Probabilistic and Similarity-Based Position Estimation from Radio Observations

Sensors
We propose a modeling approach for position estimation based on the observed radio propagation in an environment. The approach is purely similarity-based and therefore free of explicit physical assumptions.

Nonparametric Estimation for Functional Data by Wavelet Threshold

Revstat Statistical Journal, 2013
This paper deals with density and regression estimation problems for functional data. Using wavelet bases for Hilbert spaces of functions, we develop a new adaptive procedure based on a term-by-term selection of the wavelet coefficients estimators.

Kernel density classification and boosting: an L2 sub analysis [PDF]

, 2005
Kernel density estimation is a commonly used approach to classification. However, most of the theoretical results for kernel methods apply to estimation per se and not necessarily to classification.
