Long-term Off-Policy Evaluation and Learning [PDF]
arXivShort- and long-term outcomes of an algorithm often differ, with damaging downstream effects. A known example is a click-bait algorithm, which may increase short-term clicks but damage long-term user engagement. A possible solution to estimate the long-term outcome is to run an online experiment or A/B test for the potential algorithms, but it takes ...

Long-time behavior of a nonlocal Cahn-Hilliard equation with reaction [PDF]
arXiv, 2017 In this paper we study the long-time behavior of a nonlocal Cahn-Hilliard system with singular potential, degenerate mobility, and a reaction term. In particular, we prove the existence of a global attractor with finite fractal dimension, the existence of an exponential attractor, and convergence to equilibria for two physically relevant classes of ...

A Brief History of Long-Term Potentiation [PDF]
Neuron, 2017 Since the discovery of long-term potentiation (LTP) in 1973, thousands of papers have been published on this intriguing phenomenon, which provides a compelling cellular model for learning and memory. Although LTP has suffered considerable growing pains over the years, LTP has finally come of age. Here the rich history of LTP is reviewed.

Motor cortical plasticity induced by motor learning through mental practice.
Frontiers in Behavioral Neuroscience, 2015 Several investigations suggest that actual and mental actions trigger similar neural substrates. Motor learning via physical practice results in long-term potentiation (LTP)-like plasticity processes, namely potentiation of M1 and a temporary occlusion ...

A rapamycin-sensitive signaling pathway contributes to long-term synaptic plasticity in the hippocampus [PDF]
, 2002 Many forms of long-lasting behavioral and synaptic plasticity require the synthesis of new proteins. For example, long-term potentiation (LTIP) that endures for more than an hour requires both transcription and translation.

Efficient Bayesian inference for long memory processes [PDF]
arXiv, 2014 In forecasting problems it is important to know whether or not recent events represent a regime change (low long-term predictive potential), or rather a local manifestation of longer term effects (potentially higher predictive potential). Mathematically, a key question is about whether the underlying stochastic process exhibits "memory", and if so ...
