海外TECH	DEV Community	13 Interactive Animated Backgrounds for your Website using Vanta.js	https://dev.to/mulx10/13-interactive-animated-backgrounds-for-your-website-using-vanta-js-2k32	Interactive Animated Backgrounds for your Website using Vanta jsAdding interactive object animations to a website creates a delightful experience for users besides making it more appealing Adding one to the website might be much easier than you think We will look at the Vanta js library that will help us create an animated background for various elements What is Vanta js Animated website background in few lines of code    is an apt description of the library Why should we use Vanta js Vanta js works similarly to plug and play devices Injecting it into the website is just a few lines away It also supports mouse controls gyro controls for mobile devices amp touch controls Added to that it provides different background effects to choose from Lets start building up a website injected with the vanta js effect Setting Up the project Since we are starting from scratch we need to create an empty HTML template and save it as index html This step is optional if we use an already existing project lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset utf gt lt title gt lt title gt lt link href style css rel stylesheet gt lt head gt lt body gt lt script gt lt script gt lt body gt lt html gt We would need to include the assets needed to run the Vanta js background Vanta js supports THREE js as well as p js We will proceed with THREE js Include the script in the lt head gt tag lt script src gt lt script gt We will create a file named style css and add the following stuff This is just to make the scratch website look a little cooler However this is purely optional styles css container width height vh text align center display flex flex direction column justify content center align items center container h font size em font family Montserrat sans serif color FFFFFF text shadow px px DE container p font size em font family Nunito Sans sans serif color FFFFFF text shadow px px Let s startWe first create a div element inside the body that will be used by Vanta js to render the background We assign it a unique id of vantajs bg this will help us to refer to the element in javascript lt div id vantajs bg gt lt div gt We change the CSS properties of div to cover the entire screen The z index is set to so that the background does not render over the web page elements The height and width are set to cover the screen vantajs bg position absolute z index width height Vanta js has effects in its library To start we will look at the HALO effect To add the HALO effect all we need to add are two script tags lt script src latest dist vanta halo min js gt lt script gt lt script gt VANTA HALO el document getElementById vantajs bg change the element here mouseControls true touchControls true gyroControls true lt script gt The first script loads the HALO effect from the Vanta library and the second initializes the object and injects it into the element with id vantajs bg Here we go The HALO effect The entire index html looks like this lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset utf gt lt title gt lt title gt lt link href style css rel stylesheet gt lt script src gt lt script gt lt head gt lt body gt lt script src latest dist vanta halo min js gt lt script gt lt script gt VANTA HALO el document getElementById vantajs bg change the element here mouseControls true touchControls true gyroControls true lt script gt lt body gt lt html gt lt head gt lt body gt lt script src latest dist vanta halo min js gt lt script gt lt script gt var effect VANTA HALO el document getElementById vantajs bg change the element here mouseControls true touchControls true gyroControls true lt script gt lt body gt lt html gt The parameters of the effect can be tweaked according to the needs For example if the device supports gyro controls it can be turned on etc The CSS properties like background color can also be changed as per requirements More on this later A codepen demo is also linked here to demonstrate other effects available in Vanta js See the Pen VantaJS Interactive BG by Mehul Kumar Nirala MuLx on CodePen BonusAs discussed before the properties of the effects can be charged as per our requirement The rise of the dark lord I mean theme has created a need to incorporate theme toggle We can tweak the parameters of Vanta js to incorporate the same We will set a light background to update the animation Note the color values are specified in hex color codes however the format is different Later when you want to update an animation in progress with new optionseffect setOptions backgroundColor xe Later if the container changes size and you want to force Vanta to redraw at the new canvas sizeeffect resize The setOptions method can be slid inside a button onClick event to trigger the Vanta js effect background change Thank you for reading Connect with me	2021-05-31 05:37:50

海外TECH	DEV Community	Is Confusion Matrix really Confusing?	https://dev.to/kirankamatmgm/is-confusion-matrix-really-confusing-45dc	Is Confusion Matrix really Confusing After reading this blog I am sure you will not be confused with the confusion matrix Let s get started The confusion matrix is the table that is used to describe the performance of the model We can use accuracy as a metric to analyze the performance of the model then why confusion matrix What is the need for Confusion matrix So to understand this let us consider an example of the cancer prediction model Since this is a binary classification model its job is to detect cancerous patients based on some features Considering that only a few get cancer out of millions of population we consider only of the data provided has cancer positive Having cancer is labeled as and not cancer labeled as An interesting thing to note here is if a system gives the prediction as all s even then the prediction accuracy will be It is similar to writing print in model output This will have an accuracy of But this is not correct right Now that you know what is the problem and the need for a new metric to help in this situation let us see how the confusion matrix solves this problem Let us consider an example with a classification dataset having data points We get the below confusion matrix There will be two classes and would mean the person has cancer and would mean they don t have cancer By seeing this table we have different combinations of predicted and actual values Let us consider predicted values as Positive and Negative and actual values as True and False Just hold on this is easy and you will understand True Positive Interpretation Model predicted positive and it s true Example understanding The model predicted that a person has cancer and a person actually has it True Negative Interpretation Model predicted negative and it s true Example understanding The model predicted that a person does not have cancer and he actually doesn t have cancer False Positive Interpretation Model predicted positive and it s false Example understanding The model predicted that a person has cancer but he actually doesn t have cancer False Negative Interpretation Model predicted negative and it s false Example understanding The model predicted that a person does not have cancer and person actually has cancer Precision Out of all the positive classes we have predicted correctly how many are actually positive Recall Out of all the positive classes how much we predicted correctly Image credit WikipediaCalculating precision and recall for the above table Let s compare this with accuracy The model got an accuracy of but the precision of and recall of which means that percent of the correctly predicted cases turned out to be cancer cases Whereas of the cancer positives were successfully predicted by our model Consider an example where prediction is replaced by print so that we get every time Actual y Actual y Predicted y Predicted y Here accuracy will be but what happens to Precision and recall Precision becomes since TP is Recall becomes since TP is This is a classic example to understand Precision and Recall So now you understand why accuracy is not so useful for imbalanced dataset and how Precision and Recall plays a key role One important thing is to understand is when to use Precision and when to use Recall Precision is a useful metric where False Positive is of greater importance than False Negatives For example In recommendation systems like Youtube Google this is an important metric where the wrong recommendations may cause users to leave the platform Recall is a useful metric where False Negative is of greater importance than False Positive For example In the medical field detecting patients without a disease positive can be tolerated to an extent but patients with disease should always be predicted So what is the case when we are not sure whether to use Precision or Recall or what to do when one of the two is high whether the model is good To answer this let us see what is F score F score is a harmonic mean of Precision and Recall and it is a high value when Precision is equal to Recall Why not normal arithmetic mean instead of harmonic mean Because arithmetic mean gives high value when one of the two is high value but harmonic mean will be high only when both are almost equal So from our example the F score becomesF TP TP FP FN I believe after reading this Confusion matrix is not so confusing anymore Hope you learned something new here and don t forget to comment below your thoughts Thanks for reading Keep learning Keep Growing	2021-05-31 05:05:59
