海外TECH	DEV Community	Supervised Learning	https://dev.to/anurag629/supervised-learning-4o1i	Supervised LearningSupervised learning uses a training set to teach models to yield the desired output This training dataset includes inputs and correct outputs which allow the model to learn over time The algorithm measures its accuracy through the loss function adjusting until the error has been sufficiently minimized Supervised learning can be separated into two types of problems when data miningーclassification and regression Classification uses an algorithm to accurately assign test data into specific categories It recognizes specific entities within the dataset and attempts to draw some conclusions on how those entities should be labeled or defined Common classification algorithms are linear classifiers support vector machines SVM decision trees k nearest neighbor and random forest which are described in more detail below Regression is used to understand the relationship between dependent and independent variables It is commonly used to make projections such as for sales revenue for a given business Linear regression logistical regression and polynomial regression are popular regression algorithms How Supervised Learning Works In supervised learning models are trained using labelled dataset where the model learns about each type of data Once the training process is completed the model is tested on the basis of test data a subset of the training set and then it predicts the output The working of Supervised learning can be easily understood by the below example and diagram Suppose we have a dataset of different types of shapes which includes square rectangle triangle and Polygon Now the first step is that we need to train the model for each shape If the given shape has four sides and all the sides are equal then it will be labelled as a Square If the given shape has three sides then it will be labelled as a triangle If the given shape has six equal sides then it will be labelled as hexagon Now after training we test our model using the test set and the task of the model is to identify the shape The machine is already trained on all types of shapes and when it finds a new shape it classifies the shape on the bases of a number of sides and predicts the output Types of supervised Machine learning Algorithms Supervised learning can be further divided into two types of problems RegressionRegression algorithms are used if there is a relationship between the input variable and the output variable It is used for the prediction of continuous variables such as Weather forecasting Market Trends etc Below are some popular Regression algorithms which come under supervised learning Linear RegressionRegression TreesNon Linear RegressionBayesian Linear RegressionPolynomial Regression ClassificationClassification algorithms are used when the output variable is categorical which means there are two classes such as Yes No Male Female True false etc Spam Filtering Random ForestDecision TreesLogistic RegressionSupport vector Machines Advantages of Supervised learning With the help of supervised learning the model can predict the output on the basis of prior experiences In supervised learning we can have an exact idea about the classes of objects Supervised learning model helps us to solve various real world problems such as fraud detection spam filtering etc Disadvantages of supervised learning Supervised learning models are not suitable for handling the complex tasks Supervised learning cannot predict the correct output if the test data is different from the training dataset Training required lots of computation times In supervised learning we need enough knowledge about the classes of object Supervised Machine Learning ExamplesHere are some of supervised machine learning examples models used in different business applications Image and object recognitionSupervised machine learning is used to locate categorise and isolate objects from images or videos which is useful when applied to different imagery analysis and vision techniques The primary goal of image or object recognition is to identify the image accurately Example We use the ML to recognise the image precisely as if it is the image of the plane or a car or if the image is of a cat or a dog Predictive analyticsSupervised machine learning models are widely used in building predictive analytics systems which provide in depth insights into different business data points This enables the organisations to predict certain results using the output given by the system It also helps business leaders to make decisions for the betterment of the company Example We may use supervised learning to predict house prices Data having details about the size of the house price the number of rooms in the house garden and other features are needed We need data about various parameters of the house for thousands of houses and it is then used to train the data This trained supervised machine learning model can now be used to predict the price of a house Example Spam detection is another area where most organisations use supervised machine learning algorithms Data scientists classify different parameters to differentiate between official mail or spam mail They use these algorithms to train the database such that the trained database recognise patterns in new data and classify them into spam and non spam communication efficiently Sentiment analysisOrganisations can use supervised machine learning algorithms to predict customer sentiments They use the algorithms to extract and categorise important information from large data sets like emotions intent and context with little human interference This model of supervised learning is also used to predict the sentiments of the text This information is highly useful to gain insights about customer needs and help to improve brand customer engagement efforts Example Some o rganisations especially e commerce stores often try to identify the sentiments of their customer via product reviews posted on their applications or websites Reference JavapointIBMIndeed	2023-01-20

海外TECH	DEV Community	Easily Create An NFT App Using The New Infura NFT SDK TypeScript	https://dev.to/olanetsoft/easily-create-an-nft-app-using-the-new-infura-nft-sdk-typescript-3e3o	Easily Create An NFT App Using The New Infura NFT SDK TypeScriptIf you know typescript it s easy to add the ability to create mint and manage non fungible tokens NFTs to your app The Infura NFT SDK wraps REST calls to Ethereum nodes abstracting away the technical compilations and making it possible to work with NFTs with just an Infura account some configuration and a few lines of code The Infura NFT SDK also doesn t require the overhead of learning Solidity importing ABIs etc Whether you are new to web or highly experienced Infura NFT SDK makes NFTs easy Let s jump in build and deploy an ERC NFT to see how it works What is the Infura NFT SDK The Infura NFT SDK is an SDK that allows you to build and interact with NFTs easily  It s implemented in TypeScript a programming language that is a strict superset of JavaScript  The SDK includes the ability to create mint and manage NFTs and query information about them  The significant part is that it abstracts away the technical details so you can focus on the core functionality of your dApp instead of the often difficult details It s all about ease of use with Infura SDKs Supported chains include WriteEthereum Mainnet Goerli SepoliaPolygon Mainnet MumbaiReadEthereum Mainnet Goerli SepoliaPolygon Mainnet MumbaiBSC MainnetBy using the Infura NFT SDK you also get access to Infura s core functionality and infrastructure which provides access to Ethereum and other blockchains without requiring you to run a full node With the SDK you can leverage many capabilities making it easier to build and scale your dApps So let s build an NFT and see what the SDK can do Building and Deploying ERC NFTWe will build a dApp and smart contract on Ethereum and use the SDK to create a new NFT We ll do all this on the Ethereum Goerli testnet so we don t have to worry about defects or the cost of deploying to the mainnet PrerequisiteBefore getting started you need the following prerequisites Node js and its package manager NPM Verify you have Node js installed by using the following terminal command node v amp amp npm vTypeScript installedAn Infura accountA basic understanding of TypeScript and JavaScriptMetaMask InfuraThe Infura NFT SDK is really simple to use In fact most of this tutorial is just the setup and configuration needed to create a dApp Let s start by logging in to your Infura account You should be on your dashboard where you can create a new key as shown below We ll create a new key for this project Click the “Create a New Key button and fill in the required information After creating your key your project ID will be visible on your dashboard under the API KEY section as shown below Copy and keep it somewhere you ll need it later in this tutorial Set up IPFS project on Infura DashboardNow let s create an IPFS project IPFS is a PP distributed file system for storing and accessing files and other data It works well with blockchain We ll need IPFS and these credentials to upload and store the metadata of our NFT project  Head to your dashboard and create another new key by clicking “Create a Key as shown below This time we ll choose IPFS as the network This project will work on the mainnet and what we will use it for testnet After creating your key you ll see your project ID and API key secret under the API KEY section of your dashboard You ll need this later as well so copy it and keep it somewhere safe Project Setup and InstallationNext we ll set up and initialize a node js Typescript project Use the following commands in your console mkdir typescript nft demo amp amp cd typescript nft demonpm init ynpm install D typescript ts nodenpx tsc initOpen the project in your preferred development environment For example if you are using Visual Studio Code use the following command to open the project automatically code Install the Project LibrariesNext we need to install the Infura SDK and dotenv library for reading the environment variables Use the following command  npm install infura sdk dotenvYour project should have something similar to what is shown below Create a env file at your project s root and add the following variables to it INFURA PROJECT ID lt YOUR INFURA PROJECT ID gt INFURA PROJECT SECRET lt YOUR INFURA PROJECT API KEY gt WALLET PRIVATE KEY lt YOUR WALLET MNEMONIC PRIVATE KEY gt EVM RPC URL YOUR PROJECT API KEY gt INFURA IPFS PROJECT ID lt YOUR INFURA IPFS PROJECT ID gt INFURA IPFS PROJECT SECRET lt YOUR INFURA IPFS PROJECT SECRET KEY gt WALLET PUBLIC ADDRESS lt YOUR WALLET ADDRESS gt Replace lt YOUR INFURA PROJECT ID gt and lt YOUR INFURA PROJECT API KEY gt with the ID and API key from the Infura project created earlier in this tutorial Replace lt YOUR INFURA IPFS PROJECT ID gt and lt YOUR INFURA IPFS PROJECT SECRET KEY gt with the ID and API key from the IPFS  project created earlier in this tutorial On the line starting with EVM RPC URL replace lt YOUR PROJECT API KEY gt with your Infura API key lt YOUR WALLET ADDRESS gt should be replaced with your public blockchain address lt YOUR WALLET MNEMONIC PRIVATE KEY gt is your wallet s private key Note Never share your private keys mnemonic with anyone and keep them secure You can find your wallet address and private key to your wallet on MetaMask in the following steps Open MetaMask by clicking on the browser extension icon or visiting the MetaMask website Click on the three dots in the top right corner of the MetaMask window Select “Account Details from the drop down menu and click on the “Export Private Key button A pop up window will appear asking you to enter your password Enter your password and click on the “Unlock button Once your account is unlocked you can see your private key  Remember keep your private key safe and never share your private key with anyone else Also be sure you re connected to the Goerli testnet not the mainnet as shown in the image below Now that we ve successfully configured our project create a new TypeScript file nft ts at the root level Your project structure should look similar to the one below Setup Infura AuthenticationAuthentication from inside our dApp requires our PROJECT ID and PROJECT SECRET We ll load these from our new env file Create an auth object inside the nft ts using the following code snippet import config as loadEnv from dotenv import SDK Auth Metadata TEMPLATES from infura sdk load environment variables from env fileloadEnv Create an instance of the Auth class const auth new Auth   set the projectId taken from the INFURA PROJECT ID environment variable   projectId process env INFURA PROJECT ID   set the secretId taken from the INFURA PROJECT SECRET environment variable   secretId process env INFURA PROJECT SECRET   set the private key taken from the WALLET PRIVATE KEY environment variable   privateKey process env WALLET PRIVATE KEY   set the rpcUrl taken from the EVM RPC URL environment variable   rpcUrl process env EVM RPC URL   set the chainId for the Goerli testnet  chainId Goerli  set the options for IPFS  ipfs     set the project Id taken from the INFURA IPFS PROJECT ID environment variable    projectId process env INFURA IPFS PROJECT ID     set the API key secret taken from the INFURA IPFS PROJECT SECRET environment variable    apiKeySecret process env INFURA IPFS PROJECT SECRET   Instantiate the SDKconst sdk new SDK auth Configure the tsconfig json file as shown You might get an error but keep going tsconfig json is a configuration file for TypeScript projects It s used to specify the compiler options and files that should be included in the project Configure your tsconfig json with the following code snippet         compilerOptions           target ESNext Set the JavaScript language version for emitted JavaScript and include compatible library declarations           module ES Specify what module code is generated           rootDir                                   Specify the root folder within your source files           moduleResolution node Specify how TypeScript looks up a file from a given module specifier           esModuleInterop true Emit additional JavaScript to ease support for importing CommonJS modules This enables allowSyntheticDefaultImports for type compatibility           forceConsistentCasingInFileNames true Ensure that casing is correct in imports           Type Checking           strict true Enable all strict type checking options           skipLibCheck true Skip type checking all d ts files       Next add the type module to the package json file using the following code snippet type module scripts Create Token MetadataNow we re done configuring Let s get to the exciting stuff First we ll create the token metadata  Token metadata refers to additional information or data associated with a token typically an ERC or ERC token on the Ethereum blockchain This metadata can include information such as the token s name symbol image and other attributes that describe the token or give it context The metadata is stored on the blockchain and is typically represented as a URI or a URL that points to a JSON file containing the metadata Inside the nft ts file add the following code snippet It will create and store the token metadata The metadata class is from the Infura NFT SDK Note The consensys net external url is just for demo purposes here and can be replaced Define the properties of the token including its description external URL image name and attributesconst tokenMetadata Metadata openSeaTokenLevelStandard   description Fantastic creature of different emojis   external url   image await sdk storeFile     Store the image from the given URL    metadata b auto predominant fl preserve transparency v demo jpg     name Kandy Jane   attributes Log the token metadata object to the consoleconsole log Token Metadata tokenMetadata Store the token metadata and log the resultconst storeTokenMetadata await sdk storeMetadata metadata tokenMetadata console log Store Token Metadata storeTokenMetadata Create the Contract MetadataContract metadata refers to additional information or data associated with a smart contract on a blockchain network This metadata can include information such as the contract s name symbol version and other attributes that describe the contract or give it context The metadata is stored on the blockchain and is typically represented as a URI or a URL that points to a JSON file containing the metadata Create contract metadata using the following code snippet Define the properties of the collection including its description external URL image name and attributesconst collectionMetadata Metadata openSeaCollectionLevelStandard   name Emojis collection Sets the name of the collection to Emojis collection   description     A small digital image or icon used to express an idea or emotion in electronic communication Emoji s come in many forms such as smiley faces animals food and activities Sets the description of the collection  image await sdk storeFile     Sets the image property of the collection using the storeFile method    metadata b auto predominant fl preserve transparency v demo jpg The URL of the image file    external link Sets the external link property of the collection Logs the collection metadata to the consoleconsole log Collection Metadata collectionMetadata   stores the metadata using the storeMetadata methodconst storeMetadata await sdk storeMetadata metadata collectionMetadata   Logs the store metadata to the consoleconsole log Store Metadata storeMetadata  This code snippet above creates an object collectionMetadata using the openSeaCollectionLevelStandard method from the Metadata class The openSeaCollectionLevelStandard method creates standard collection level metadata compatible with OpenSea a leading marketplace for NFTs It sets the collection s name description image and external link properties stores the metadata using the storeMetadata method then logs it and stores it in the console for debugging Create a New Contract and Mint an NFTAdd the following code to create a new contract and mint an NFT using the Infura NFT SDK Most of this functionality comes to us from our new NFT SDK Create a new contractconst newContract await sdk deploy   deploys a new contract using the sdk deploy method  template TEMPLATES ERCMintable     sets the template for the contract to ERCMintable  params     name Contract                   sets the name of the contract as Contract     symbol EMOJI                         sets the symbol of the contract as EMOJI     contractURI storeMetadata             sets the contract URI with the storeMetadata  console log Contract Address n newContract contractAddress   logs the contract address to the console mint an NFTconst mint await newContract mint   mints a new NFT using the mint method from the new contract  publicAddress     process env WALLET PUBLIC ADDRESS     xeEABCCDEEACebeC sets the public address of the wallet if not set it will use the given address  tokenURI storeTokenMetadata                 sets the token URI with the storeTokenMetadata const minted await mint wait             waits for the minting process to completeconsole log Minted minted               logs the minted NFT to the consoleThis code creates a new contract using the sdk deploy method and sets the template for the contract to ERCMintable  Then it sets the contract s name symbol and contract URI  The contract address is logged for debugging It then mints a new NFT using the mint method from the new contract and sets the wallet s public address If not specified it uses the given address and then sets the token URI with the storeTokenMetadata Finally it waits for the minting process to complete and logs the minted NFT to the console Let s test it out ts node esm nft tsYou should see something similar to what is shown below Verify Contract on Account and Goerli EtherscanFinally let s verify the contract using a blockchain explorer on the Goerli Etherscan Go to the Goerli Ethereum testnet site and paste the transaction hash from your output above as shown below You should see the details That was easy We successfully utilized the Infura NFT SDK to build deploy and mint an NFT on the Goerli testnet Import token on MetaMaskLet s look at our new NFT from a front end perspective using MetaMask First we have to import our wallet to MetaMask Click “Import Tokens as shown in MetaMask Be sure you are connected to the Goerli Testnet as shown Copy and paste the contract address to import your token on MetaMask as shown below And there it is An easy and fast way to add NFTs to your dApps You can use the SDK now to manage the NFTs and more see the docs for current capabilities Verify Minted NFT on OpenSeaWe ve successfully imported the minted NFT on MetaMask but now let s verify on OpenSea tesnet Connect your wallet and view your new NFT You should have something similar to what is shown below For reference here s the OpenSea link to the NFT created You can find the complete code on a GitHub repository here ConclusionIn conclusion the new Infura NFT SDK for TypeScript is a powerful tool for developers looking to incorporate NFTs into their dApps With its easy to use functions and comprehensive features this SDK makes it simple to deploy mint and manage NFTs on the Ethereum blockchain  Sign up and start building I d love

海外TECH	Engadget	Keychron's Q1 Pro is a wireless version of its best mechanical keyboard	https://www.engadget.com/keychron-q1-pro-bluetooth-customizable-keyboard-143008367.html?src=rss	Keychron x s Q Pro is a wireless version of its best mechanical keyboardKeychon has been an ascending name in the mechanical keyboard world for a while now The company strikes a good balance between features and price and it s also not shy about releasing new models meaning whatever you re after it likely has a solution Unless you wanted a premium aluminum deck with a wireless option that is Finally that gap has been filled by the Q Pro a flagship fully customizable keyboard complete with Bluetooth connectivity Surprising as it may seem higher end customizable keyboards often don t offer wireless thanks to their tendency for metal housings Keychron s Q Pro then will be of great interest to those who want to fully configure their own keyboard but also want the convenience of Bluetooth As the name suggests the Q Pro is heavily based on the original Q model which Keychron launched in late Like its predecessor the Pro model features a gasket design a double gasket in fact hot swappable switches and QMK VIA compatibility open source software for easy remapping of any key There s also the option of an aluminum rotary knob for things like volume control or zoom or brightness or whatever else you might want it for and the obligatory RGB As with all Keychron models it s also compatible with Mac Windows and Android or all three at the same time thanks to the option to connect to multiple Bluetooth devices We were big fans of the original Q which offered a relatively affordable entry point into the fully customizable keyboard world And it s a bit of a weird world at that with configurations price and availability varying wildly Perhaps two of the higher profile competitors for the Q are the GMMK Pro starting at barebones or pre built and the recently released Sense from Drop starting at barebones or pre built James Trew EngadgetIn a slight break from tradition the Q Pro is being launched via Kickstarter The benefit here being the chance to grab one at an early bird price The barebones model is available for if you already have your own switches and keycaps Or for you can get the pre assembled kit Given that a set of keycaps or switches often cost more than on their own the complete kit does represent a pretty decent value Once you have everything setup or out of the box if you go fully assembled Bluetooth pairing is merely a key combo away As noted earlier you can connect the Q Pro to up to three devices of any type thanks to the switch around the back for Windows Android and MacOS There are even spare key caps in the box for the differing keys on Microsoft vs Apple layouts Of course if you want to connect over USB C instead that s still an option Battery life will largely depend on how ham you go with the RGB With no backlighting at all Keychron claims you can expect about hours of use on a full charge If you re demure with it that number drops to Keychron doesn t give an estimate for hardcore full power RGB but expect it to be less With the model Keychron sent for testing the gasket design appears to have a bit more flex in it than the original Q but that doesn t translate to a softer typing experience thankfully The supplied red switches are comparable to Cherry reds in resistance but of course you can choose whatever you want in fact it s encouraged It s hard to make a like for like comparison without having a rival product with the same switches and keycaps but overall the Drop Sense and GMMK Pro feel a little stiffer on the gasket side of things resulting in a snappier type As always your mileage and preferences will vary Regardless if you wanted a premium aluminum customizable keyboard with Bluetooth connectivity the Keychron Q Pro is likely your best if not only choice right now	2023-01-20 14:30:08
