Default Initialization for Tensorflow LSTM states and weights?

痴心易碎 提交于 2020-05-26 09:54:27
问题 I am using the LSTM cell in Tensorflow. lstm_cell = tf.contrib.rnn.BasicLSTMCell(lstm_units) I was wondering how the weights and states are initialized or rather what the default initializer is for LSTM cells (states and weights) in Tensorflow? And is there an easy way to manually set an Initializer? Note: For tf.get_variable() the glorot_uniform_initializer is used as far as I could find out from the documentation. 回答1: First of all, there is a difference between the weights of a LSTM (the

Missing example of a Member Initializer List on p. 184 of Programming Principles and Practice Using C++, 2nd ed

问题 I'm currently having trouble with part of Chapter 6 of "Programming: Principles and Practice Using C++" (2nd ed, 3rd printing). According to the book's index, an example of a member initializer list is on page 184. Part of page 184 reads as follows: "Here, we'll just provide two member functions to give us a more convenient way of initializing Tokens: class Token { public: char kind; // what kind of token double value; // for numbers: a value }; We can now initialize ("construct") Token

Designated Initializer of UITextView

问题 When I create a new subclass of UITextView in the Xcode 6 Beta, the following code is automatically provided. import UIKit class TerminalView: UITextView { init(frame: CGRect) { super.init(frame: frame) // Initialization code } } The previous code (completely provided by Xcode with nothing removed) gives the following error. Must call a designated initializer of the superclass 'UITextView' As far as I know, the designated for all subclasses of UIView is -initWithFrame: (or in Swift, init

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

I have following code var list = new List<IMyCustomType>(); list.Add(new MyCustomTypeOne()); list.Add(new MyCustomTypeTwo()); list.Add(new MyCustomTypeThree()); this of course works, but I'm wondering: how can I

Unable to programatically create a UIViewController in Swift

问题 When I try to create an instance of a UIViewController in Swift , all the inherited initialisers are unavailable, even though I didn't define any designated inits in the view controller (or anything else, FWIW). Also, if I try to display it by making it the root view controller, it never gets displayed: func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { // Override point for customization after application launch. window

Property / field initializers in code generation

问题 I'm generating code in a visual studio extension using CodeDom and plain code strings. My extension reads a current classes declared fields and properties using reflection and generates contructors, initializers, implements certain interfaces, etc. The generator class is simple: public class CodeGenerator < T > { public string GetCode () { string code = ""; T type = typeof(T); List < PropertyInfo > properties = t.GetProperties(); foreach (PropertyInfo property in properties) code += "this." +
