Understanding temperature tuning in energy-based models
Peter W Fields, Vudtiwat Ngampruetikorn, David J Schwab +1
Generative models of complex systems often require post-hoc parameter adjustments to produce useful outputs. For example, energy-based models for protein design are sampled at an a…
Optimization and variability can coexist
Marianne Bauer, William Bialek, Chase Goddard +6
Many biological systems perform close to their physical limits, but promoting this optimality to a general principle seems to require implausibly fine tuning of parameters. Using e…
Exact minimax entropy models of large-scale neuronal activity
Christopher W. Lynn, Qiwei Yu, Rich Pang +2
In the brain, fine-scale correlations combine to produce macroscopic patterns of activity. However, as experiments record from larger and larger populations, we approach a fundamen…
Exactly solvable statistical physics models for large neuronal populations
Christopher W. Lynn, Qiwei Yu, Rich Pang +2
Maximum entropy methods provide a principled path connecting measurements of neural activity directly to statistical physics models, and this approach has been successful for popul…
Probabilistic models, compressible interactions, and neural coding
Luisa Ramirez, William Bialek, Stephanie E. Palmer +1
In physics we often use very simple models to describe systems with many degrees of freedom, but it is not clear why or how this success can be transferred to the more complex biol…
Quantum disorder in the two-dimensional pyrochlore Heisenberg antiferromagnet
S. E. Palmer, J. T. Chalker
We present the results of an exact diagonalization study of the spin-1/2 Heisenberg antiferromagnet on a two-dimensional version of the pyrochlore lattice, also known as the square…
Order induced by dipolar interactions in a geometrically frustrated antiferromagnet
S. E. Palmer, J. T. Chalker
We study the classical Heisenberg model for spins on a pyrochlore lattice interacting via long range dipole-dipole forces and nearest neighbor exchange. Antiferromagnetic exchange…
