Co-GNN 的三个例子:所有节点都选择标准动作,所有节点都选择隔离动作,以及节点根据其当前状态选择最适合的动作。 当动作选择完后,第二个图神经网络 环境网络(Environment network)会在一个通过所选择的动作重写的子图上进行消息传递并得到输出。Co-GNNs其中一个特点是两个网络同时通过一个损失函数进行训练,就像两个网络...
https://towardsdatascience.com/understanding-backpropagation-algorithm-7bb3aa2f95fd 反向传播(Backpropagation)是一种用于训练神经网络的优化算法,通过计算损失函数关于网络参数的梯度,并利用这些梯度来更新参数,以最小化损失函数。 前向传播(Forward Propagation):将输入数据通过神经网络进行正向传播,计算每一层的输出。
A neural network is defined as a parallel processing network system that mimics the information processing capabilities of the human brain. It consists of interconnected neurons and can process numerical data, knowledge, thinking, learning, and memory. ...
Towards End-to-end Text Spotting with Convolutional Recurrent Neural Networks In this work, we jointly address the problem of text detection and recognition in natural scene images based on convolutional recurrent neural networks. We propose a unified network that simultaneously localizes and recognizes...
We study the use of a time series encoder to learn representations that are useful on data set types with which it has not been trained on. The encoder is formed of a convolutional neural network whose temporal output is summarized by a convolutional attention mechanism. This way, we obtain ...

High-dimensional data can be converted to low-dimensional codes by training a multilayer neural network with a small central layer to reconstruct high-dimensional input vectors. Gradient descent can be used for fine-tuning the weights in such "autoencoder" networks, but this works well only if ...
