Kavli Affiliate: Maria Monzani | Summary:In this article we describe Cohort Organized Learning (CoOL), a method for clustering data without explicit distance or similarity computations. Herein, we will describe CoOL, derive the gradients determined by expectation maximization to train the networks, show how to monitor convergence during training and evaluate the clusters after training, and […]

Figueredo Burgos, Anna M Hakimi, Kathryn Xie, Mo Mao, Mahekdeep Kaur, Antionette Spina, Katie Choi, Longhui Qui, Teresa E Lever, Fiona M Gribble, Frank Reimann, Martin G Myers, Alice E Adriaenssens and Zachary A Knight | Summary: Nausea arises from activation of specialized neurons in […]
Kavli Affiliate: Karunesh Ganguly | Authors: Ryan Golden, Mingxiao Wei, Samantha Coury, Aviv Mizrahi-Kliger, Karunesh Ganguly and Maxim Bazhenov | Summary: Sleep supports both the consolidation of new memories and the forgetting of others, but how the cortex flexibly controls these outcomes remains poorly understood. Recent work has shown that two types of Up states […]
Kavli Affiliate: Marcelo Mattar | Authors: Jonathan Nicholas, Sixing Chen and Marcelo G Mattar | Summary: Flexible decision making depends on retrieving and recombining memories. Yet because this process unfolds covertly, its governing principles remain unknown. Here we use gaze reinstatement to uncover the hidden dynamics and computational logic of memory retrieval during flexible behavior. […]
Kavli Affiliate: Roberto Maiolino | Summary:We present an analysis of a sample of 36 Little Red and Blue Dots (LRDs and LBDs) at $2.26<z<7.89$, identified by JWST in the GOODS fields. While both categories are selected to have broad Balmer lines, both of them are extremely X-ray weak. Both classes share the same location on […]
Kavli Affiliate: Tomotake Matsumura | Summary:TIFUUN (THz Integral Field Units with Universal Nanotechnology) is an ultra-wideband mm-submm wave imaging spectrometer that capitalizes on the highly scalable integrated superconducting spectrometer technology. TIFUUN has two slots for integral field units (IFUs), which can jointly be optimized as open-hardware for each astronomical observation in terms of spatial and […]
Kavli Affiliate: Roberto Maiolino | Summary:High-redshift little red dots (LRDs) are compact sources characterized by V-shaped spectral energy distributions (SEDs), broad emission lines, and often prominent Balmer breaks. Their high number density and apparently large black hole masses suggest that they are essential to the early evolution of galaxies and supermassive black holes (SMBHs); however, […]
