Results on memory-limited U-shaped learning

Lorenzo Carlucci, John Case, Sanjay Jain, Frank Stephan
2007 Information and Computation  
Our results show that the question of the necessity of U-shaped learning in this memory-limited setting depends on delicate tradeoffs between the learner's ability to remember its own previous conjecture  ...  In the present paper we consider, then, the question of the necessity of U-shaped learning for some learning models featuring memory limitations.  ...  Introduction and motivation In Section 1.1, we explain U-shaped learning and in Section 1.2 memory-limited learning.  ...

On the Necessity of U-Shaped Learning

Lorenzo Carlucci, John Case
2013 Topics in Cognitive Science  
We present results about the necessity of U-shaped learning in classical models of learning as well as in models with bounds on the memory of the learner.  ...  ., connectionism vs. nativism) are often judged on their ability of modeling or accounting for U-shaped behaviour.  ...  We occasionally refer to this form of U-shaped learning as semantic U-shaped learning. For mathematical convenience we will state our results in terms of non-U-shapedness.  ...

Context-Dependent Learning Interferes with Visuomotor Transformations for Manipulation Planning

Q. Fu, M. Santello
2012 Journal of Neuroscience  
Our results suggest that learning generalization of dexterous manipulation is fundamentally limited by context-specific learning of motor actions and competition between vision-based motor planning and  ...  The first task involved manipulating a U-shaped object that can afford two actions by grasping different parts of the same object.  ...  This result is consistent with the above result from the U-shaped object.  ...

OSS-Net: Memory Efficient High Resolution Semantic Segmentation of 3D Medical Data [article]

Christoph Reich, Tim Prangemeier, Özdemir Cetin, Heinz Koeppl
2021 arXiv   pre-print
A key limitation of 3D CNNs on voxelised data is that the memory consumption grows cubically with the training data resolution.  ...  While O-Nets are significantly more memory efficient than 3D CNNs, they are limited to simple shapes, are relatively slow at inference, and have not yet been adapted for 3D semantic segmentation of medical  ...  Occupancy networks and related implicit representation approaches, such as [6, 23, 29] , are memory efficient yet limited to represent simple 3D shapes and do not generalize well to unseen shapes [30  ...

As a result, our network architecture requires only a moderate number of parameters while keeping a high level of expressiveness which enables learning from very little data.  ...  Experiments on real and synthetic datasets demonstrate that our network achieves higher accuracy compared to a purely variational approach while at the same time requiring two orders of magnitude less  ...  Learned Shape Priors.  ...
