Longer-term effects of Head Start
- American Economic Review
, 2002
"... Abstract Public early intervention programs like Head Start are often justified as investments in children. Yet nothing is known about the long-term effects of Head Start. This paper draws on unique data from the Panel Study of Income Dynamics to provide new evidence on the effects of Head Start on ..."

parenting skills which might affect all children. Moreover, it is possible that what one child learns may "spillover" to siblings. In general, in the fixed effects framework, spillovers will tend to result in downward biased estimates of the effect of Head Start because they reduce the differences

1On the Identifiability of Overcomplete Dictionaries via the Minimisation Principle Underlying K-SVD
, 2013
"... This article gives theoretical insights into the performance of K-SVD, a dictionary learning algorithm that has gained significant popularity in practical applications. The particular question studied here is when a dictionary Φ ∈ Rd×K can be recovered as local minimum of the minimisation criterion ..."

it is further demonstrated that given a finite number of training samples N, such that N / logN = O(K3d), except with probability O(N−Kd) there is a local minimum of the K-SVD criterion within distance O(KN−1/4) to the generating dictionary. Index Terms dictionary learning, sparse coding, K-SVD, finite sample

1 Cognitive Beamforming Made Practical: Effective Interference Channel and Learning-Throughput Tradeoff
, 809
"... Abstract — This paper studies the transmit strategy for a secondary link or the so-called cognitive radio (CR) link under opportunistic spectrum sharing with an existing primary radio (PR) link. It is assumed that the CR transmitter is equipped with multi-antennas, whereby transmit precoding and pow ..."

interferes with the PR terminals, this paper proposes a practical CB scheme utilizing a new idea of effective interference channel (EIC), which can be efficiently estimated at the CR transmitter from its observed PR signals. Somehow surprisingly, this paper shows that the learning-based CB scheme
