Almost usually things are a little bit more complex and to support scalability we should split things apart. So we can define various files containing different resources dictionaries, i.e. resources for UI controls' themes, resources for texts and so on, then we merge them all together in App.xaml ...

The goal of backpropagation is to optimize the weights so that the neural network can learn how to correctly map arbitrary inputs to outputs. Each layer has its own set of weights, and these weights must be tuned to be able to accurately predict the right output given input. A high level overview ...

Activation functions also known as transfer function is used to map input nodes to output nodes in certain fashion. They are used to impart non linearity to the output of a neural network layer. Some commonly used functions and their curves are given below: Sigmoid Function The sigmoid is a ...

Softmax regression (or multinomial logistic regression) is a generalization of logistic regression to the case where we want to handle multiple classes. It is particularly useful for neural networks where we want to apply non-binary classification. In this case, simple logistic regression is not suf...

Enter command "tsc --init" and hit enter. Before that we need to compile ts file with command "tsc app.ts" now it is all defined in below config file automatically. Now, You can compile all typescripts by command "tsc". it will automatically create ".js&q...

As already mentioned you can declare an unordered map of any type. Let's have a unordered map named first with string and integer type. unordered_map<string, int> first; //declaration of the map first["One"] = 1; // [] operator used to insert the value first["Two"] = 2...

unordered_map<data_type, data_type> variable_name; //declaration variable_name[key_value] = mapped_value; //inserting values variable_name.find(key_value); //returns iterator to the key value variable_name.begin(); // iterator to the first element variable_name.end(); // iterator t...

The following steps need to be done in the app.ionic.io Create an account or login into your ionic account Click "New App" in the Dashboard and give name for your app I named my app as 'MyIonicApp' In the overview section of this newly created app, there will be a ID...

Most Singleton examples use MonoBehaviour as the base class. The main disadvantage is that this Singleton class only lives during run time. This has some drawbacks: There is no way of directly editing the singleton fields other than changing the code. No way to store a reference to other assets...

CHMOD Calculation CHMOD is binary. _ / _ _ _ / _ _ _ / _ _ _ = _/4+2+1/4+2+1/4+2+1 = 777 = _/rwx/rwx/rwx = 777 Therefore _rwx = _/4+2+1 = 7 D / _ _ _ / _ _ _ / _ _ _ (‘D’ = directory, another use is L = Link) So e.g. _rwxr_xr_x = _/rwx/rx/r_x = 755

Action Mailer provides hooks into the interceptor methods. These allow you to register classes that are called during the mail delivery life cycle. An interceptor class must implement the :delivering_email(message) method which will be called before the email is sent, allowing you to make modificat...

We have seen in those examples (ex_1, ex_2) how to use and override the pagination classes in any generic class base view. What happens when we want to use pagination in a function based view? Lets also assume that we want to create a function based view for MyModel with PageNumberPagination, res...

If you have: operator fun <R> String.invoke(block: () -> R) = { try { block.invoke() } catch (e: AssertException) { System.err.println("$this\n${e.message}") } } You can write the following DSL-like code: "it should return 2" { parse("1 + 1").bu...

Small object optimization is a technique which is used within low level data structures, for instance the std::string (Sometimes referred to as Short/Small String Optimization). It's meant to use stack space as a buffer instead of some allocated memory in case the content is small enough to fit with...

Suppose you are creating a function that requires no arguments when it is called and you are faced with the dilemma of how you should define the parameter list in the function prototype and the function definition. You have the choice of keeping the parameter list empty for both prototype and d...

One option for doing this is to export the pipe from within the package itself. This may be done in the 'traditional' zzz.R or utils.R files that many packages utilise for useful little functions that are not exported as part of the package. For example, putting: #' Pipe operator #' #' @name %&gt...
