Medical image fusion techniques can fuse medical images from different morphologies to make the medical diagnosis more reliable and accurate, which play an increasingly important role in many clinical applications. To obtain a fused image with high visual quality and clear structure details, this paper proposes a convolutional neural network (CNN) based medical image fusion algorithm. which preserves more geometric features and generates more complex shapes. With the development of deep learning techniques, learning based methods have become effective tools in solving shape synthesis problems.

2005-08-01 · Section 4 presents the generalization of the feedforward neural networks in the geometric algebra system and it describes the generalized learning rule across different geometric algebras. For completeness this section explains the training of geometric neural networks using genetic algorithms. The objective is to find the optimal value of theta for which the loss function is minimized. Vector Notation of Parameters. The way we reach the objective is to update θ with some small random value, i.e. delta theta Δ θ which is a collection of change in w and change in b.

## Graph Neural Networks are a very flexible and interesting family of neural networks that can be applied to really complex data. As always, such flexibility must come at a certain cost.

I am going to use the geometric pyramid rule to determine the amount of hidden layers and neurons for each layer. The general rule of thumb is if the data is linearly separable, use one hidden layer and if it is non-linear use two hidden layers. I am going to use two hidden layers as I already know the non-linear svm produced the best model.

### the hidden layer. A geometric pyramid rule was proposed which state that for a three-layer neural network having n input neurons and m output neurons, then the hidden layer would have nm neurons [11]. It was indicated that the number of neurons should be between the size of the input neurons and the size of output neurons [12].

A rough approximation can be obtained by the geometric pyramid rule proposed by Masters (1993). found a simple network architecture with which the best accuracy can be obtained by increasing the network depth without increasing computational cost by much. We call it deep pyramid CNN. The pro-posed model with 15 weight layers out-performs the previous best models on six benchmark datasets for sentiment classiﬁ-cation and topic categorization. Figure 1: Multilayer Feedforward Neural Network with Two Hidden Layers. One rough guideline for choosing the number of hidden neurons in many problems is the geometric pyramid rule. It states that, for many practical networks, the number of neurons follows a pyramid shape, with the number decreasing from the input towards the output.

However, these methods do not deﬁne convo-lutions on large-scale point clouds to learn geometric fea-tures in the local neighborhoods. TangentConv [33

Hyperbolic geometry has been applied to neural networks, to problems of computer vision or natural language processing [17, 13, 36, 8]. More recently, hyperbolic neural networks [10] were proposed, where core neural network operations are in hyperbolic space.

However, some thumb rules are available for calculating the number of hidden neurons. A rough approximation can be obtained by the geometric pyramid rule proposed by Masters (1993). For a three layer network with n input and m output neurons, the hidden layer would have $ \sqrt{n \times m} $ neurons.
