Synaptic, transcriptional and chromatin genes disrupted in autism
The genetic architecture of autism spectrum disorder involves the interplay of common and
rare variants and their impact on hundreds of genes. Using exome sequencing, here we …

Differential privacy and robust statistics
C Dwork, J Lei - Proceedings of the forty-first annual ACM symposium …, 2009 - dl.acm.org
We show by means of several examples that robust statistical estimators present an excellent
starting point for differentially private estimators. Our algorithms use a new paradigm for …

Consistency of spectral clustering in stochastic block models
We analyze the performance of spectral clustering for community extraction in stochastic block
models. We show that, under mild conditions, spectral clustering applied to the adjacency …
