    Equivariant learning of a transferable three-dimensional classical density functional

    Bingqing Cheng

    cond-mat.stat-mech · cond-mat.soft · cs.LG · physics.chem-ph · physics.comp-ph

    Liquids exhibit collective behavior that depends sensitively on thermodynamic conditions, interfaces and confinement, yet predicting each new state commonly requires a separate atomistic simulation. Classical density functional theory offers a reusable variational description, but its central excess free-energy functional is generally unknown, and learned approximations have largely remained restricted to planar or lower-dimensional settings....

    Thermodynamics of Learning: A Typed Four-Component Accounting of Memory, Fit, and Value

    Akihito Sudo

    cond-mat.stat-mech · cs.IT · cs.LG

    What a finite learning device has recorded and what will hold value for it on future tasks are not the same quantity. We develop a typed accounting for finite-state learning devices that separates four components: a training-side fit functional $Φ_{\mathrm{fit}}$, the record-correlation stock $J_{D}=I(M;D)$, an update-side search ledger $σ_{M}$, and an operational capital value $V(M;T,b)$. This value is the work gap between an informed...
