📣Out now: New work from @yinizhang2011 @ftrevorc & @JosephineLukito on network amplification on Twitter! The paper examined how elites amplify politicized information and how this varies based on partisan identity of the influencer. Read here: tandfonline.com/doi/abs/10.1…

Graduate school is a dangerously vulnerable place this vulnerability can enable tremendous growth choose your community and your mentors carefully. Be kind to yourself and each other Mentors, it is an honor to support people in this stage. and this is painfully easy to forget.

I’m going to begin today with a bold claim: Being an applied statistician is a lot like being an ethnographer.

Looks like I am doing an excellent job in the end (of my PhD) 😃
to do good research, you must first be confused

Would you want your whole face to be seen while wearing a #mask? Brazilian artist Jorge Silva Roriz paints parts of customers' faces onto white protective masks, ensuring that details like facial hair color and skin tone would be closely matched to his customers' faces.

Suffering from overconfident softmax scores? Time to use energy scores! Excited to release our NeurIPS paper on "Energy-based Out-of-distribution Detection", a theoretically motivated framework for OOD detection. 1/n Paper: arxiv.org/abs/2010.03759 (w/ code included)

A stat-graph problem! answer might be trivial? Suppose a two block stochastic blockmodel on n nodes that is below the reconstruction threshold. an oracle puts every node into one of n/k "pre-groups" of k nodes. no group has nodes in both blocks. can you reconstruct? idk.

The third phase of the ENCODE project presents an online registry of over 1,200,000 human and mouse candidate functional elements that regulate genes, and the findings are presented in a collection of papers. See the collection here. go.nature.com/2DlgiRe

Large-scale applications of SURF to 104 RBP datasets from @ENCODE_NIH indicate a diverse involvement of RBPs in ATR events and highlights broader positioning preferences for their interaction with RNA. (4/5)

SURF-identified protein-RNA interaction regions (1) carry ATR-specific sequence motifs, (2) are enriched for somatic mutations from both ICGC and TCGA, and (3) exhibit differential activity between TCGA acute myeloid leukemia tumor and GTEx whole blood samples. (5/5)
