Gradient-based meta-learning has been shown to be expressive enough to approximate any learning algorithm. While previous such methods have been successful in meta-learning tasks, they resort to simple gradient descent during meta-testing. Our primary contribution is the MT-net, which enables the meta-learner to learn on each layer’s activation space a subspace that the task-specific learner pe...

New and unexpected results are presented regarding the nonlinear interactions between a wavepacket and a vortical mean flow, with an eye towards internal wave dynamics in the atmosphere and oceans and the problem of ‘missing forces’ in atmospheric gravity-wave parametrizations. The present results centre around a prewave-breaking scenario termed ‘wave capture’, which differs significantly from ...

Pruning and quantization are core techniques used to reduce the inference costs of deep neural networks. Among state-of-the-art pruning techniques, magnitude-based algorithms have demonstrated consistent success in reduction both weight feature map complexity. However, we find that existing measures neuron (or channel) importance estimation for such procedures at least one two limitations: (1) ...

During layerwise growth of crystals, capillarity governs the generation of new crystal layers. Theory predicts that the line tension of the layer edge determines, via the characteristic two-dimensional capillary length L(c), the rates of generation and initial growth of the new layers. To test the correlation between L(c) and the rate of layer generation, we used in situ Tapping Mode Atomic For...

Photopolymerization-based Additive Manufacturing (AM), a technique in which product is built layerwise fashion by local curing of liquid monomer, increasingly being adopted the high-tech sector. Nevertheless, industry still faces several challenges to improve repeatability quality, as recognized authorities on AM standardization. It commonly that there need for an in-depth understanding, in-sit...

Static shape actuation and dynamic control of nozzles can improve their performance, accuracy, reliability, etc. A new curved laminated piezothermoelastic hexahedral finite element is formulated based on the layerwise constant shear angle theory and it is used for modeling and analysis of piezothermoelastic conical shell structures subjected to control voltages for static shape actuation and dy...
