Fig. 1. Neural network model topology and layer configuration represented by a p-dimensional input, k-neuron hidden layer and 1 output variable. The p-by-k input weights matrix IW, k-by-1 layer weights column vector lw′¯, and the corresponding biases b(1)¯ and b(2) for each la...
Therefore, we investigated whether the convolutional neural network (CNN) model could recognize the tribofilms formed from OBCS and classify image data of the elemental distributions of these tribofilms into high and low friction-coefficient groups. The CNN model classifies only output values, and it...
Machine learning potentials have become an important tool for atomistic simulations in many fields, from chemistry via molecular biology to materials science. Most of the established methods, however, rely on local properties and are thus unable to take
since the network will need to use a diversity of possible patterns to be able to process novel patterns. The more complex the pattern, the larger the training set required. The three input values are then followed by a –1 or 1 value that indicates whether the patient...
2.4. Setup of the Artificial Neural Network Having an appropriate set of learning data at hand, the final practical issue is to design a feasible neural network for computing the above coefficients {𝑎𝑗}4𝑗=1{aj}j=14. In any case, to keep the computational costs at a low level, ...
In the course of this endeavor, the paper introduces a neural network analog akin to the statistical concept of power, thereby unveiling its potential as a more encompassing metric for the comprehensive evaluation and projection of network quality. The challenge posed by the task of detecting ...
Artwork: A neural network can learn by backpropagation, which is a kind of feedback process that passes corrective values backward through the network.Simple neural networks use simple math: they use basic multiplication to weight the connections between different units. Some neural networks learn ...
PINNs take into account the underlying PDE, i.e. the physics of the problem, rather than attempting to deduce the solution based solely on data, i.e. by fitting a neural network to a set of state-value pairs. The idea of creating physics-informed learning machines that employ systematically...
While network packet-level simulators are accurate, they are slow since they need to simulate the forwarding, transmission, and propagation of each and every packet. On the other hand, traditional analytical models such as queuing theory are fast but not accurate in the presence of non-markovian...
We combine the curvature-based graph neural network and AGN to propose the Curvature-based Adaptive Graph Neural Network (CurvAGN). We apply CurcAGN to predicting the protein-ligand binding affinity. We train and validate our model on the publicly available standard PDBbind-v2016 dataset, and sh...
