Rarely categorical, always high-dimensional: how the neural code changes along the cortical hierarchy

Posted by dbos Columbia, This Week: Neuroscience

Kavli Affiliate: Eric D. Siggia | Authors: Stefano Fusi and Liam Paninski | Summary: The brain is highly structured both at anatomical and functional levels. However, within individual brain areas, neurons often exhibit very diverse and seemingly disorganized responses. A more careful analysis shows that these neurons can sometimes be grouped together into specialized subpopulations […]

Quantitative guiding of developmental cell fate transitions using gene-free modelling

Posted by dbos Rockefeller, This Week: Neuroscience

Kavli Affiliate: Eric D. Siggia | Authors: Ismail Hajji, Eric D Siggia, Francis Corson and Wolfgang Keil | Summary: During development, cells gradually assume specialized fates via changes of transcriptional dynamics in thousands of genes. Terminal cell identities are then stabilized through the convergence of gene regulatory network dynamics and the accumulation of epigenetic DNA […]

Ultrafast optical control of charge orders in kagome metals

Posted by dbos Berkeley, This Week: Nanoscience

Kavli Affiliate: Joel E. Moore | First 5 Authors: Yu-Ping Lin, Vidya Madhavan, Joel E. Moore, , | Summary: We show that ultrafast optical pump pulses provide effective control over charge orders in the kagome metals $A$V$_3$Sb$_5$ with $A=$ K, Rb, and Cs. Starting from the real charge density waves (rCDWs) at the $p$-type Van […]

M-VAR: Decoupled Scale-wise Autoregressive Modeling for High-Quality Image Generation

Posted by dbos Berkeley, This Week: Nanoscience

Kavli Affiliate: Feng Wang | First 5 Authors: Sucheng Ren, Yaodong Yu, Nataniel Ruiz, Feng Wang, Alan Yuille | Summary: There exists recent work in computer vision, named VAR, that proposes a new autoregressive paradigm for image generation. Diverging from the vanilla next-token prediction, VAR structurally reformulates the image generation into a coarse to fine […]
