Quick Guide: Neural Networks using JavaScript

  • Below is the image shown the simple neural network: – – – – In the above image, following are the things that are significant: – – – Input Layer: It is the layer through which the data is passed.
  • Weight in neural networks is simply a number which is multiplied with the information coming from the input layer.
  • Tools – – For doing neural networks in JavaScript, we would require the following tools: – – – Google Chrome or Safari (Any browser you like; I am going to use Safari in the article.)
  • XAMPP (Optional; it is used to run the code locally) – – – – Languages – – The following languages will be used: – – – HTML5 – – JavaScript (for writing a neural network) – – – – Library – – For this article, we will use the tensorflow.js…
  • The following script has to be added in the HTML body to include the TensorFlow in the project: – – – script /script – – – Essential Steps – – Almost every neural network follows the following essential steps: – – – Collecting the input data (in tensors form) step…

Machine Learning: TensorFlow in JavaScript

  • DOCTYPE html – html lang=en – head – meta charset=UTF-8 – meta name=viewport content=width=device-width, initial-scale=1.0 – meta http-equiv=X-UA-Compatible content=ie=edge – – script /script – script have also added our own custom JavaScript (index.js) file by using the following line of script: – – script data-src=index.js/script – – Now in order…
  • The following example shows the addition of two tensor (make sure that the dimensions or shapes of both the tensors are same; they must be incompliance with the Matrix mathematics rules): – – let twoDimensionalTensor = tf.tensor([1,2,3,4], shape=[2,2], dtype=float32); – let addition = should expect the element-wise addition.
  • The output is as follows: – Tensor – [[2, 4], – [6, 8]] (as expected) – – Multiplication using Tensors – – We can multiple two tensors (element-wise) by using the following code: – – let twoDimensionalTensor = tf.tensor([1,2,3,4], shape=[2,2], dtype=float32); – let multiplcation = output is: – Tensor -…
  • This is how you can multiple two tensors (real matrix multiplication): – – let twoDimensionalTensor = tf.tensor([1,2,3,4], shape=[2,2], dtype=float32); – let multiplcation = the above case, as the number of columns of first matrix is same as the number of rows of the second matrix (in this case the same…
  • The output is: – Tensor – [[7 , 10], – [15, 22]] – – Summary – – In this article, we have learned the basics of Machine or Deep Learning in general and TensorFlow.js in particular.

Development Guide: Web Games using JavaScript

  • As we are developing a 2D game using HTML and JavaScript, here is how we can initiate the canvas in HTML: – – canvas id=canvas width=500 height=500/canvas – – – id is used to access the HTML canvas in JavaScript.
  • In order to get the context of the canvas, we would use getContext function of the canvas object as follows: – – let context = canvas.getContext(2d); – – As you can see in the previous line of code that we have specified 2d as the parameter of the getContext (for…
  • The source code to draw the complete image into canvas is as follows: – – let cardsprite = new Image(); – cardsprite.src = cardsprite.png – – function draw() { – let width = cardsprite.width; – let height = cardsprite.height; – canvas.width = width; – canvas.height = height; – context.drawImage(cardsprite, 0,…
  • draw function is created; in that function, first the width and the height of the cardsprite is saved in the temporary variables and then the canvas size is resized to the cardsprite width and height (you may resize the image, but that is not the scope of this article).
  • The code for animation (JavaScript file) is as follows: – – let canvas = context = canvas.getContext(2d); – – let cardsprite = new Image(); – cardsprite.src = cardsprite.png – – let width; – let height; – let singleCardWidth; – let singleCardHeight; – let xframe = 0; – let yframe =…

How to use Google API in Python

  • Introduction – – In this multi-part series, I’ll break down the code that allowsyouto leverage Google APIs to the most basic level (even for Python), so you can customize as necessary for your app, whether it’s running as a command-line tool or something server-side in the cloud backending Web or…
  • If you’ve got the book and played around with ourGoogle+ APIexample, you’ll find this code familiar, if not identical I’ll go into more detail here, highlighting the common code for generic API access andthenbring in the G+-relevant code later.
  • To talk to a Google API, you need theGoogle APIs Client Library for Python, specifically and install the library in your usual way, for example: – – $ pip install -U google-api-python-client # or pip3 for 3.
  • Now craft the following lines of code in your command-line tool, using the instead: = # copied from project credentials VERSION, developerKey=API_KEY) – – Take the API key you copied from the credentials page and assign to theAPI_KEYvariable as a string.
  • In our short example we’re going to do a simple search for python in public Google+ posts, so for theAPIvariable, use the string’plus’.

Introduction and usage of System Design Primer

  • Evolutionary study: To gather archaeological samples and analyzed for To profile DNA from blood, hair, and skin cells for criminal identification and forensics – – – – Stages of PCR PCR is divided into 3 stages: Denaturation Anneal – – ExtensionThe denaturation stage – – The double-stranded DNA sample is…
  • The annealing stage – – primers anneal to the DNA strands when the temp.
  • Melting Temperature Formula (18-25 bp range) – – Tm = 2(A+T) + 4(G+C) – – The forward and reverse primers should be having similar Tm, or else amplification will be less efficient.Melting Temperature should be between 55C and 65C.
  • The simplest API function iscalcTm, which uses nearest-neighbor thermodynamics to calculate the melting temperature of a provided DNA sequence: – – import primer3 – thermodynamic functions andcalcHeterodimer.
  • All three functions return a namedtuple: – – from primer3 import calcHeterodimer – res = ‘TTGGTCCCATAAGGGTCGG’) – print(res) – – thermoresult( – structure_found=True, – tm=39.92795428766294, – ds=-370.12644214999796, – dh=-127200.0, – dg=-12405.28396717814, – align_end_1=16, – align_end_2=17 – ) – – print res.tm – 39.92795428766294 – – For more detailed documentation and…

Why GraphQL: Advantages, Disadvantages & Alternatives – RWieruch

  • However, by having a query language such as GraphQL which is used on the server-side but also on the client-side, the client decides what data it needs by making only one request to the server.
  • In the case of Facebooks development of mobile applications with GraphQL, it reduced the network usage dramatically, because with GraphQL one had to make only one request and the amount of data transferred decreased.
  • As you can see, one query already requests multiple resources (author, article), which are called fields in GraphQL, and only a particular set of nested fields for these fields (name, urlSlug for article) even though the entity itself may offer more data in its GraphQL schema (e.g. description, releaseData for…
  • Whereas the server application offers a GraphQL schema where it defines all available data with its hierarchy and types, a client application only queries the required data.
  • Thus GraphQL can be used to connect both worlds but also to fulfil the requirements (e.g. network usage requirements, nested relationships of data, fetching only the required data) of each client application without having a dedicated API for each client.
