Dynamic Programming for Instance Annotation in Multi-instance Multi-label Learning
Anh T. Pham, Raviv Raich, Xiaoli Z. Fern
Labeling data for classification requires significant human effort. To reduce labeling cost, instead of labeling every instance, a group of instances (bag) is labeled by a single b…
Confidence-constrained joint sparsity recovery under the Poisson noise model
E. Chunikhina, R. Raich, T. Nguyen
Our work is focused on the joint sparsity recovery problem where the common sparsity pattern is corrupted by Poisson noise. We formulate the confidence-constrained optimization pro…
An Information Geometric Framework for Dimensionality Reduction
Kevin M. Carter, Raviv Raich, Alfred O. Hero
This report concerns the problem of dimensionality reduction through information geometric methods on statistical manifolds. While there has been considerable work recently present…
Information Preserving Component Analysis: Data Projections for Flow Cytometry Analysis
Kevin M. Carter, Raviv Raich, William G. Finn +1
Flow cytometry is often used to characterize the malignant cells in leukemia and lymphoma patients, traced to the level of the individual cell. Typically, flow cytometric data anal…
FINE: Fisher Information Non-parametric Embedding
Kevin M. Carter, Raviv Raich, William G. Finn +1
We consider the problems of clustering, classification, and visualization of high-dimensional data when no straightforward Euclidean representation exists. Typically, these tasks a…
