Natural World Distribution via Adaptive Confusion Energy Regularization

no code implementations1 Jan 2021 Yen-Chi Hsu, Cheng-Yao Hong, Wan-Cyuan Fan, Ding-Jie Chen, Ming-Sui Lee, Davi Geiger, Tyng-Luh Liu

The Fine-Grained Visual Classification (FGVC) problem is notably characterized by two intriguing properties, significant inter-class similarity and intra-class variations, which cause learning an effective FGVC classifier a challenging task.

Quantum Interference for Counting Clusters

no code implementations3 Jan 2020 Rohit R Muthyala, Davi Geiger, Zvi M. Kedem

Counting the number of clusters, when these clusters overlap significantly is a challenging problem in machine learning.

Quantum Clustering and Gaussian Mixtures

no code implementations29 Dec 2016 Mahajabin Rahman, Davi Geiger

In this algorithm, each class is described by a Gaussian distribution, defined by its mean and covariance.

Quantum Pairwise Symmetry: Applications in 2D Shape Analysis

no code implementations2 Feb 2015 Marcelo Cicconet, Davi Geiger, Michael Werman

A pair of rooted tangents -- defining a quantum triangle -- with an associated quantum wave of spin 1/2 is proposed as the primitive to represent and compute symmetry.

Complex-Valued Hough Transforms for Circles

no code implementations2 Feb 2015 Marcelo Cicconet, Davi Geiger, Michael Werman

This paper advocates the use of complex variables to represent votes in the Hough transform for circle detection.

A Geometric Descriptor for Cell-Division Detection

no code implementations15 Jan 2013 Marcelo Cicconet, Italo Lima, Davi Geiger, Kris Gunsalus

We describe a method for cell-division detection based on a geometric-driven descriptor that can be represented as a 5-layers processing network, based mainly on wavelet filtering and a test for mirror symmetry between pairs of pixels.
