Pruning Neural Networks at Initialization: Why are We Missing the Mark? [article]

Jonathan Frankle, Gintare Karolina Dziugaite, Daniel M. Roy, Michael Carbin
2021 arXiv   pre-print
Recent work has explored the possibility of pruning neural networks at initialization.  ...  This property suggests broader challenges with the underlying pruning heuristics, the desire to prune at initialization, or both.  ...  We do not identify a cause for why these methods struggle to prune in a specific fashion at initialization (and often only at initialization), and we believe that this is an important question for future  ...

Autonomous mobile robot global self-localization using Kohonen and region-feature neural networks

Jason A. Jan�t, Ricardo Gutierrez, Troy A. Chase, Mark W. White, John C. Sutton
1997 Journal of Robotic Systems  
This article presents and compares two neural network-based approaches to global selflocalization (GSL) for autonomous mobile robots using: (1) a Kohonen neural network; and (2) a region-feature neural  ...  The classification rate of both approaches are comparable and, thus, worthy of presentation. The observed pros and cons of both approaches are also discussed.  ...  Figure 9 marks with an ϫ all nodes that are pruned.  ...

Affective Monitoring: A Generic Mechanism for Affect Elicitation

R. Hans Phaf, Mark Rotteveel
2012 Frontiers in Psychology  
Affective monitoring is considered a local match-mismatch process within a module of the neural network.  ...  For affect to become conscious, large-scale synchronization of the oscillations over the network and the construction of emotional experiences are required.  ...  ACKNOWLEDGMENTS We are grateful to Bram T. Heerebout, A. E. Yoram Tap, and William H. Thompson for their help in various stages of this work.  ...

Adolescent impulsivity phenotypes characterized by distinct brain networks

2012 Nature Neuroscience  
Hypofunctioning of a specific orbitofrontal cortical network was associated with likelihood of initiating drug use in early adolescence.  ...  As these networks have not yet been described, we identified distinct cortical and subcortical networks underlying successful inhibitions and inhibition failures in a large sample (n = 1,896) of 14-year-old  ...  Notably, these findings also suggest a degree of independence at the neural level for the deficits in inhibitory control associated with ADHD and the propensity for drug abuse.  ...

Spikelets in Pyramidal Neurons: Action Potentials Initiated in the Axon Initial Segment That Do Not Activate the Soma

Martina Michalikova, Michiel W. H. Remme, Richard Kempter, Volker Steuber
2017 PLoS Computational Biology  
Therefore, APs are the basis of neural function, yet some of their fundamental features are still not well understood.  ...  Here, we propose that spikelets occur when an AP initiated at the axon initial segment only propagates down the axon, but fails to activate sodium currents in the soma and dendrites.  ...  Acknowledgments We thank M. Brecht, E. Chorev, N. Maier, S. Schreiber, and R. D. Traub for valuable discussions.  ...

Language and connectionism: the developing interface

Mark S. Seidenberg
1994 Cognition  
After a difficult initial period in which connectionism was perceived as either irrelevant or antithetical to linguistic theory, connectionist concepts are now beginning to be brought to bear on basic  ...  I consider how connectionist concepts may be relevant to issues concerning the representation of linguistic knowledge; the role of a priori constraints on acquisition; and the poverty of the stimulus argument  ...  This level of description is useful but misses certain generalizations that can only be stated at the level of network behavior.  ...

Dynamic systems modelling using genetic programming

Mark P. Hinchliffe, Mark J. Willis
2003 Computers and Chemical Engineering  
A comparison with neural networks reveals that GP is able to match the accuracy of the network predictions but is more expensive computationally.  ...  Two case studies are used to demonstrate the performance of this technique. The first example uses the multi-objective algorithm to improve the parsimony of the evolved model structures.  ...  initial neural network prediction error is substantially higher than that of the GP algorithm.  ...
