Multitask Bregman Clustering

Traditional clustering methods deal with a single clustering task on a single data set. However, in some newly emerging applications, multiple similar clustering tasks are involved simultaneously. In this case, we not only desire a partition for each task, but also want to discover the relationship among clusters of different tasks. It’s also expected that the learnt relationship among tasks ca...

Co-Clustering for Multitask Learning

This paper presents a new multitask learning framework that learns a shared representation among the tasks, incorporating both task and feature clusters. The jointlyinduced clusters yield a shared latent subspace where task relationships are learned more effectively and more generally than in state-of-the-art multitask learning methods. The proposed general framework enables the derivation of m...

Multitask Multiple Kernel Learning

We present a general regularization-based framework for Multi-task learning (MTL), in which the similarity between tasks can be learned or refined using `pnorm Multiple Kernel learning (MKL). Based on this very general formulation (including a general loss function), we derive the corresponding dual formulation using Fenchel duality applied to Hermitian matrices. We show that numerous establish...

Task Clustering and Gating for Bayesian Multitask Learning

Modeling a collection of similar regression or classification tasks can be improved by making the tasks ‘learn from each other’. In machine learning, this subject is approached through ‘multitask learning’, where parallel tasks are modeled as multiple outputs of the same network. In multilevel analysis this is generally implemented through the mixed-effects linear model where a distinction is m...

Multitask Clustering of Genes in Different Cell Types

Understanding the behavior of a complex network of genes within an organism remains a challenging question in biology. Higher organisms may have tens of thousands of genes interacting and self-regulating in complex ways, and sophisticated regulatory mechanisms are prevalent – for instance, to maintain homeostasis, trigger responses to environmental stimuli, or repair cellular damage. In such a ...
