SE537604C2 - Metod för optimering av en parameter i ett

‪Agata Charzyńska‬ - ‪Google Scholar‬

torch.nn.Parameter是继承自torch.Tensor的子类，其主要作用是作为nn.Module中的可训练参数使用。它与torch.Tensor的区别就是nn.Parameter会自动被认为是module的可训练参数，即加入到parameter()这个迭代器中去；而module中非nn.Parameter()的普通tensor是不在parameter中的。 注意到，nn.Parameter的对象的requires_grad属性的默认值是True，即是可被训练的，这与torth.Tensor对象的默认值相反。 在nn.Module类中 首先可以把这个函数理解为类型转换函数，将一个不可训练的类型 Tensor 转换成可以训练的类型 parameter 并将这个 parameter 绑定到这个 module 里面 ( net.parameter () 中就有这个绑定的 parameter ，所以在参数优化的时候可以进行优化的)，所以经过类型转换这个 self.v 变成了模型的一部分，成为了模型中根据训练可以改动的参数了。. 使用这个函数的目的也是想让某些变量在学习的 1. torch.nn.Parameter () 函数. 官方用法是：. self.v = torch.nn.Parameter(torch.FloatTensor(hidden_size)) 1.

Assigning a Tensor doesn’t have such effect. According to my understanding, this means nn.Parameter will be added to a module’s parameters list automatically and Variable will not. Generall optimizer will compute the gradients of modeule.parameters ().

An ANN is based on a collection of connected units or nodes called artificial neurons, which loosely model the neurons in a biological brain. Each connection, like the synapses in a biological brain, can Real-time measurements of key effluent parameters play a highly crucial role in wastewater treatment. In this research work, we propose a soft sensor model based on deep learning which combines stacked autoencoders with neural network (SAE-NN). Firstly, based on experimental data, the secondary variables (easy-to-measure) which have a strong correlation with the biochemical oxygen demand (BOD5 No other knowledge you need to predict, so it is fine to say that the parameters of the linear model are 2.

It sub-classes the Variable class. The difference between a Variable and a Parameter comes in when associated with a module. Neural Networks (NNs) are the typical algorithms used in Deep Learning analysis. NNs can take different shapes and structures, nevertheless, the core skeleton is the following: So we have our inputs (x), we take the weighted sum of them (with weights equal to w), pass it through an activation function f (.) and, voilà, we obtain our output. The following are 30 code examples for showing how to use torch.nn.Parameter().These examples are extracted from open source projects.

在看过很多博客的时候发现了一个用法self.v = torch.nn.Parameter (torch.FloatTensor (hidden_size)),首先可以把这个函数理解为类型转换函数，将一个不可训练的类型Tensor转换成可以训练的类型parameter并将这个parameter绑定到这个module里面 (net.parameter ()中就有这个绑定的parameter，所以在参数优化的时候可以进行优化的)，所以经过类型转换这个self.v变成了 parameter (nn.Parameter) – parameter to append; extend(parameters)[source] 等价于python list 的 extend 方法。 参数说明: parameters (list) – list of parameters to append; 卷积层 class torch.nn.Conv1d(in_channels, out_channels, kernel_size, stride=1, padding=0, dilation=1, groups=1, bias=True) By the way, a torch.nn.Parameter is a Tensor subclass , which when used with torch.nn.Module gets automatically added to the list of its parameters and appears in e.g., in parameters() or named_parameters() iterator. Adding a torch.nn.Tensor on the other hand doesn’t have such an effect. The following are 30 code examples for showing how to use torch.nn.Module().These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. Parameters: gate_nn (torch.nn.Module) – A neural network that computes attention scores for each feature. feat_nn (torch.nn.Module, optional) – A neural network applied to each feature before combining them with attention scores.
