RegGNN, a graph neural network architecture for many-to-one regression tasks with application to functional brain connectomes for IQ score prediction, developed in Python by Mehmet Arif Demirtaş (demirtasm18@itu.edu.tr).This work has been published in Brain Imaging and Behavior. ...
Train a Convolutional Neural Network for Regression Object Detection Using YOLO v3 Deep Learning Feature Learning, Layers, and Classification A CNN is composed of an input layer, an output layer, and many hidden layers in between. These layers perform operations that alter the data with the in...
This option creates a model using the default neural network architecture, which for a neural network regression model, has these attributes: The network has exactly one hidden layer. The output layer is fully connected to the hidden layer and the hidden layer is fully connected to the input ...
2.1.4 Siamese neural network Siamese architecture has been used for recognition or verification applications especially for one-shot learning tasks where the number of training samples for a single category is very small [21]. The main goal of this architecture is to learn a similarity index from...

We propose a neural network (NN) architecture, the Element Spatial Convolution Neural Network (ESCNN), towards the airfoil lift coefficient prediction task. The ESCNN outperforms existing state-of-the-art NNs in terms of prediction accuracy, with two ord
Ultimately, for purposes of regression each of the plotted latent spaces is equally valid and provides similar prediction errors; though additional investigation may be needed in the future to reveal additional differences for applications such as generative machine learning. Fig. 2: Visualization of ...
It can be shown that linear networks are equivalent to standard regression models. It should be noted that one of the advantages of neural networks is the ability to include a variety of information that is not readily included in simple linear models such as ARMA models, such as rainfall, ...
