What is the bias
A perceptron can be seen as a function that maps an input (real-valued) vector x to an output value f(x) (binary value):
where w is a vector of real-valued weights and b is a our bias value.
The bias is a value that shifts the decision boundary away from the origin (0,0) and ...

Referring to non-static members in initializer lists before the constructor has started executing can result in undefined behavior. This results since not all members are constructed at this time. From the standard draft:
§12.7.1: For an object with a non-trivial constructor, referring to
any no...
SSIS tasks required.
Data Flow Task: As the script component is only available in the data flow.
Script Component: Inside this we will use variables and play with there values.
Steps
There are two methods to access variables inside of script component

Magics whose name begins with just one % take as argument the rest of the line and are called line magics. Magics that begin with a double percent sign %% take a multi-line argument and are called cell magics.
A commonly used magic is %timeit, a wrapper around the Python's timeit.timeit function, f...
Crontab contains cron jobs, each related to a specific task. Cron jobs are composed of two parts, the cron expression, and a shell command to be run:
* * * * * command/to/run
Each field in the above expression * * * * * is an option for setting the schedule frequency. It is composed of minute,...
A common need for random numbers it to generate a number that is X% of some max value. this can be done by treating the result of NextDouble() as a percentage:
var rnd = new Random();
var maxValue = 5000;
var percentage = rnd.NextDouble();
var result = maxValue * percentage;
//suppose NextDoub...

Many biological questions can be translated into a DNA sequencing problem. For instance, if you want to know the expression level of a gene you can: copy its mRNAs into complementary DNA molecules, sequence each of the resulting DNA molecules, map those sequences back to the reference genome, and th...
LRU Cache
The following example code demonstrates a possible implementation of the LruCache class for caching images.

Here string value is key for bitmap value.

This is done by adding a button, dialog box and iframe as explained below.
The examples below use MDL for look and feel because it is used by Google forms and so it makes the additional elements look fairly seamless.
Dialog boxes may require a polyfill if you plan to support older browsers.
The value of GOOGLE-FORM-PREFILLED-URL should look something like this:
https://docs.google.com/forms/.../?usp=pp_url&entry.1739003583=labelname1
jQuery('#googleFormButton').click(showGoogleForm)
jQuery('#googleFormButton').attr('googleFormsURL', 'GOOGLE-FORM-PREFILLED-URL')
Add a new function called showGoogleForm and adapt the follow code to suit. Note for simplicity this example does not contain any error checking which should be added in a production environment.
The url should look something like this:
