Classification with Sparse Overlapping Groups
Binary logistic regression with a sparsity constraint on the solution plays a vital role in many high dimensional machine learning applications. In some cases, the features can be grouped together, so that entire subsets of features can be selected or zeroed out. In many applications, however, this can be very restrictive. In this paper, we are interested in a less restrictive form of structure...
متن کاملImage Restoration using Total Variation with Overlapping Group Sparsity
Image restoration is one of the most fundamental issues in imaging science. Total variation (TV) regularization is widely used in image restoration problems for its capability to preserve edges. In the literature, however, it is also well known for producing staircase-like artifacts. Usually, the high-order total variation (HTV) regularizer is an good option except its oversmoothing property. I...
متن کاملUnequal Gain of Equal Resources across Racial Groups
The health effects of economic resources (eg, education, employment, and living place) and psychological assets (eg, self-efficacy, perceived control over life, anger control, and emotions) are well-known. This article summarizes the results of a growing body of evidence documenting Blacks’ diminished return, defined as a systematically smaller health gain from economic resources and psychologi...
متن کاملImpact of Trust in Colleagues and Management on Knowledge Sharing within and across Work Groups
Knowledge sharing is crucial for firms in order to be able to develop skills and competences, increase value, and sustain competitive advantages. The ability of transferring knowledge from one unit to another increases firm performance. Several elements influencing the decision whether to share or conceal knowledge can be identified. In this paper we analyse the impact of trust on knowledge sha...
متن کاملZero-Shot Learning Across Heterogeneous Overlapping Domains
We present a zero-shot learning approach for text classification, predicting which natural language understanding domain can handle a given utterance. Our approach can predict domains at runtime that did not exist at training time. We achieve this extensibility by learning to project utterances and domains into the same embedding space while generating each domain-specific embedding from a set ...
