Ember is the framework of choice for most researchers doing machine learning. As a choice for research purposes, it's a no-brainer. You can access the open source code here: https://github.com/elastic/ember

Ember is an excellent way to explore the essential data science concepts and enables you to immediately start to use the tools and services you might need.

What Else Will You Need to Make the Most Out of Ember?

Ember helps you build a variety of different applications from the ground up. It's ideal for building more complex applications that need many components and integrations.

Ember is just what it says on the tin: it gives you the whole framework, and then you can build your own. You can even use the Javascript community in their projects to help you get started!

If you want to use Node, Ember is your best bet. However, suppose you don't use Node. In that case, you can still use Node in your projects by compiling your application to JavaScript, and that means you can also use AWS Lambda with LambdaJS, DynamoDB with DynamoDBjs, and all of the other pre-packaged Node modules.

Ember makes it easy for people to find each other and collaborate on projects.

Don't get carried away with all the details of building your application. Ember already does most of the heavy lifting; all you need to know is how to code. Ember has a great community to help you along the way.

How Do I Get Started?

You can take a few routes when you want to get started with Ember.

After reading this post, the first thing you should try is Ember's Live Hackathon, hosted at the EmberCamp Conference every year.

EmberCamp offers a variety of learning opportunities and gives people the chance to get hands-on with Ember. You can learn from speakers, meet other people interested in Ember, build your projects, and meet other Ember experts.

Use LambdaJS to Build Your Machine Learning Applications.

LambdaJS is an open-source, hosted, event-driven serverless computing platform that enables developers to build complex applications that are fault-tolerant, fast, and scalable.

You can create LambdaJS Lambda functions in any language and use them as part of your applications. As long as you compile your application to JavaScript, you can use LambdaJS Lambda functions to process your data.

Let's review some examples to show you what you can do with LambdaJS.

First, add a Lambda function to your app by running the following command in the directory where you are storing your project:

$ yarn add -D session:js -D session.promise

Then, add the following to your .npmrc :

import 'session' ; require ( 'session.promise' ) . add ({ params : { url : 'http://localhost:3000/esports/watch.json' , handler : function ( callback ) { const { event } = event . data.items; session . run ( 'Lambda' , { url : `http://localhost:3000/esports/watch.json?callback=callback` , handler : callback }); }, pause : function () { session . run ( 'Lambda' ); }, run : function ( state ) { var items = state . items . map ( function ( key ) { return { id : key , content : ` ${ key } - {{ items [ state . items . length - 1 ] }} ` }; }); for ( let i = 0 ; i < items . length ; i ++ ) { items . push ( { items [ i ]. id : i , content : items [ i ]. content , items [ i ]. timestamp : items [ i ]. timestamp + items [ i ]. timestamp + 1000 , } ); } } );

You can then execute your Lambda function, and your Ember app will listen for changes to the contents of the Sports dataset file and respond.

First, our function uses Session.promise to ensure that our browser will always have the latest data.

Then, the function updates the Sports dataset file to reflect the updates to the API.

To make this work in Ember, we will need to listen for updates to the Sports dataset file:

$ ember g view sport - updated-players

Here is what it looks like in action:

But There Is a Better Way!

Instead of directly polling for changes to the Sports dataset, we can make updates to the Sports dataset on our own and request the updates from our Lambda function.

In other words, we can make our version of a Lambda function.

Since LambdaJS is event-driven, we will want to request our server to update the Sports dataset so that our function will respond correctly when the dataset changes.

To build a Lambda function from scratch, you must install the following NodeJS modules and the CodeUnit style guide.

Install the following npm modules and Git commands for your project:

$ npm install -g d3 npm install -g gulp npm install -g nodemon npm install -g bower npm install -g ember-cli $ ember install ember-cli -production

In your project, run npm to ensure your Ember app is not running.

Now, update your file.js to have the following:

const bootstrap = require ( 'bootstrap' ); const EmberApp = Ember.application.create (); bootstrap( EmberApp, [ '$ionicApp' , '$ionicStore' , '$location' , '$state' , '$stateParams' ], { url : 'http://localhost:3001/api' , method : 'POST' , headers : { 'Content-Type' : 'application/json' }, body : { headerImage : 'https://cdn.atlassian.com/images/labs/ionic-bundle-angular.png' , headers : { 'Cache-Control' : 'no-cache' }, content : '{ "text":"Your team's players", "display":"table" }' , }, };

and run npm start again.

Using the Default Angular-Cli Project Template to Make Our New Ember App.

Now, to set up a Lambda function, run the following commands:

$ ember g template - echo '<div class="page-header">' + '<div class="page-header-onclick">' + '</div>' > {{ form.forEach({c => c.onclick = c.onclick}).join('')} {{ pageTitle }} < h2 class = "page-header-title" > {{ pageTitle }} </ h2 > </ div > </ div >

Copy and paste this page-header template into your new file.js .

Click on the index route in the Ember app and click on the app template link.

Add the following code to the app template:

< template > < div class = "page-header" > < div class = "page-header-onclick" > < button class = "btn btn-block" ( click ) = "updatePlayer(rescue.pullButton)" > Update player < /button> < /div> < /div> </ template >

Update your files and then reload your Ember app:

$ ember g EmberApp --update --tag my-team-updated

You should see an update to your team's players.

Using the DataStream API

Now that we have set up a Lambda function to update our Sports dataset, let's use that to retrieve the updated data.

Summary

If you have a collection of information, it might not make sense to process it. Instead of processing your data, why not just provide a way for others to make new requests to your information collection and collect new data?

For example, imagine you have an archive with records that can be downloaded. Your collection of records might consist of a spreadsheet with a list of companies.

An excellent way to think about this problem is to think about the records in the collection in terms of stock exchange:

You create records as blocks of data, such as companies.

  • Block A records represent companies.
  • Block B records represent individual company data.

You can use a Lambda function to provide a way to request information about companies. You can find more information about Lambda functions in the Lambda docs.

In our application, we are using the AWS Lambda library to help us process the data. You can find the library's source code on GitHub.
