In this example we will design a "measure" layer, that outputs the accuracy and a confusion matrix for a binary problem during training and the accuracy, false positive rate and false negative rate during test/validation. Although Caffe already has a Accuracy layer, sometimes you want some...

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...

public void setCardColorTran(CardView card) { ColorDrawable[] color = {new ColorDrawable(Color.BLUE), new ColorDrawable(Color.RED)}; TransitionDrawable trans = new TransitionDrawable(color); if(Build.VERSION.SDK_INT > Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1) { card.setB...

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...

Create the /etc/init.d/cassandra startup script. Edit the contents of the file: #!/bin/sh # # chkconfig: - 80 45 # description: Starts and stops Cassandra # update daemon path to point to the cassandra executable DAEMON=<Cassandra installed directory>/bin/cassandra start() { ...

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

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...

BottomSheet DialogFragment opens up in STATE_COLLAPSED by default. Which can be forced to open to STATE_EXPANDEDand take up the full device screen with help of the following code template. @NonNull @Override public Dialog onCreateDialog(Bundle savedInstanceState) { BottomSheetDialog dialog = ...

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...

In PHP, variable values have an associated "truthiness" so even non-boolean values will equate to true or false. This allows any variable to be used in a conditional block, e.g. if ($var == true) { /* explicit version */ } if ($var) { /* $var == true is implicit */ } Here are some fun...

For the most printing clients, is extremely useful to know if a print job has finished or failed. The Java Print Service API provide some functionalities to get informed about these scenarios. All we have to do is: provide an implementation for PrintJobListener interface and register this impl...

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...
