A note on insufficiency and the preservation of Fisher information [PDF]

arXiv, 2011
Kagan and Shepp (2005, Amer. Statist.) presented an elegant example of a mixture model for which an insufficient statistic preserves Fisher information. This note uses the regularity property of differentiability in quadratic mean to provide another explanation for the phenomenon they observed.

Combining Alphas via Bounded Regression [PDF]

Risks 3(4) (2015) 474-490, 2015
We give an explicit algorithm and source code for combining alpha streams via bounded regression. In practical applications typically there is insufficient history to compute a sample covariance matrix (SCM) for a large number of alphas. To compute alpha allocation weights, one then resorts to (weighted) regression over SCM principal components ...

A rare case of right sided aortic arch with aberrant left subclavian artery [PDF]

Perspectives In Medical Research, 2017
A right-sided aortic arch is a rare congenital defect of the aorta. It is seen in approximately 0.1% of population. It is of 3 subtypes some of which are associated with cyanotic congenital heart diasease and some are associated with esophageal and ...

Comment on "First observation of doubly charmed baryon Xi_cc+" [PDF]

arXiv, 2002
We speculate on a possible interpretation of events selected by the SELEX collaboration and stress an insufficient evidence for the observation of doubly charmed baryon.

Complete resolution of vertebrobasilar dissection and aneurysm following treatment of subclavian steal physiology

Journal of Vascular Surgery Cases and Innovative Techniques
Subclavian steal syndrome results from subclavian artery stenosis that results in retrograde blood flow through the ipsilateral vertebral artery. Rarely, this retrograde flow can affect the vertebrobasilar junction and cause vertebrobasilar insufficiency,

Transfer Learning based Detection of Diabetic Retinopathy from Small Dataset [PDF]

arXiv, 2019
Annotated training data insufficiency remains to be one of the challenges of applying deep learning in medical data classification problems. Transfer learning from an already trained deep convolutional network can be used to reduce the cost of training from scratch and to train with small training data for deep learning.

Towards Discriminability and Diversity: Batch Nuclear-norm Maximization under Label Insufficient Situations [PDF]

arXiv, 2020
The learning of the deep networks largely relies on the data with human-annotated labels. In some label insufficient situations, the performance degrades on the decision boundary with high data density. A common solution is to directly minimize the Shannon Entropy, but the side effect caused by entropy minimization, i.e., reduction of the prediction ...
