Partial Membership Latent Dirichlet Allocation
Chao Chen, Alina Zare, Huy Trinh +3
Topic models (e.g., pLSA, LDA, sLDA) have been widely used for segmenting imagery. However, these models are confined to crisp segmentation, forcing a visual word (i.e., an image p…
Hyperspectral Unmixing with Endmember Variability using Partial Membership Latent Dirichlet Allocation
Sheng Zou, Alina Zare
The application of Partial Membership Latent Dirichlet Allocation(PM-LDA) for hyperspectral endmember estimation and spectral unmixing is presented. PM-LDA provides a model for a h…
Multiple Instance Hyperspectral Target Characterization
Alina Zare, Changzhe Jiao, Taylor Glenn
In this paper, two methods for multiple instance target characterization, MI-SMF and MI-ACE, are presented. MI-SMF and MI-ACE estimate a discriminative target signature from imprec…
Heart Beat Characterization from Ballistocardiogram Signals using Extended Functions of Multiple Instances
Changzhe Jiao, Princess Lyons, Alina Zare +2
A multiple instance learning (MIL) method, extended Function of Multiple Instances (FUMI), is applied to ballistocardiogram (BCG) signals produced by a hydraulic bed sensor. The…
Instance Influence Estimation for Hyperspectral Target Signature Characterization using Extended Functions of Multiple Instances
Sheng Zou, Alina Zare
The Extended Functions of Multiple Instances (eFUMI) algorithm is a generalization of Multiple Instance Learning (MIL). In eFUMI, only bag level (i.e. set level) labels are needed…
Buried object detection using handheld WEMI with task-driven extended functions of multiple instances
Matthew Cook, Alina Zare, Dominic Ho
Many effective supervised discriminative dictionary learning methods have been developed in the literature. However, when training these algorithms, precise ground-truth of the tra…
Adaptive coherence estimator (ACE) for explosive hazard detection using wideband electromagnetic induction (WEMI)
Brendan Alvey, Alina Zare, Matthew Cook +1
The adaptive coherence estimator (ACE) estimates the squared cosine of the angle between a known target vector and a sample vector in a whitened coordinate space. The space is whit…
