Please me mindful of importing all necessary libraries required. This example uses InMemoryDbService from angular-in-memory-web-api to provide the JSON data from mock API. Live demo service.ts: import { Injectable } from '@angular/core'; import { Headers, Http } from '@angular/http'; import...

The machine learns to predict an output when given an input. Each training case consists of an input and a target output. Regression The target ouput takes continuous values. Predicting the price of a stock Predicting a house price Classification The target output is a class label. Wha...

The machine has to automatically determine the ideal behavior to maximize its performance. For example: Using reinforcement learning you can also make a computer program that can complete a Mario level (MarI/O - Machine Learning for Video Games).

Unsupervised learning allows us to approach problems with little or no idea what our results should look like. We can derive structure from data where we don't necessarily know the effect of the variables. The most common type of unsupervised learning is cluster analysis or clustering. It is the ta...

Many modern Image Processing algorithms use patches are their basic element to work on. For instance one could denoise patches (See BM3D Algorithm). Yet when building the image form the processed patches we have many results for the same pixel. One way to deal with it is taking the average (Empir...

There are two ways to push an element to an array: array_push and $array[] = The array_push is used like this: $array = [1,2,3]; $newArraySize = array_push($array, 5, 6); // The method returns the new size of the array print_r($array); // Array is passed by reference, therefore the original ar...

This is a simple code creating 6 3d-subplots and in the end syncing the color displayed in each of them. c_fin = [0,0]; [X,Y] = meshgrid(1:0.1:10,1:0.1:10); figure; hold on; for i = 1 : 6 Z(:,:,i) = i * (sin(X) + cos(Y)); ax(i) = subplot(3,2,i); hold on; grid on; surf(X, Y, Z(...

MQTT is an publish/subscribe "lightweight" messaging protocol for use on top of the TCP/IP protocol.

First of all you need to initialize the angularfire modules in your app module like this: const firebaseConfig = { apiKey: 'XXXXXXXXXX', authDomain: 'XXXXXXXXXX', databaseURL: 'XXXXXXXXXX', storageBucket: 'XXXXXXXXXX', messagingSenderId: 'XXXXXXXXXX' }; You can get this keys by...

Once you have it on your app, just import it: import { AngularFireDatabase } from 'angularfire2/database'; constructor (private _af: AngularFireDatabase) {} With this Observable List you can access to a list of items under a path, for example if you have root/items/food you can get food items l...

CoAP(Constrained Application Protocol) provides a request/response interaction model between application endpoints typically used along with REST.RFC

Bukkit has a system called Event Priorities to help plugins handle events in the correct older. The seven priorities are (in older from first executed to last): Lowest Low Normal (default) High Highest Monitor If you are planning to cancel a lot of events (e.g. protection plugin) it would...
