Tech Stories

In this episode , I tried to explain the concept of Artificial Neural network with out any MathsANN:An artificial neural network is an attempt to simulate the network of neurons that make up a human brain so that the computer will be able to learn things and make decisions in a humanlike manner.Neurons are information messengersa hidden layer is located between the input and output of the algorithm.Backpropagation is an algorithm used in artificial intelligence (AI) to fine-tune mathematical weight functions and improve the accuracy of an artificial neural network's outputs

In this episode I covered the USE CASE OF UPI- TRANSACTION What is Clustering?Clustering or cluster analysis is a machine learning technique, which groups the unlabelled dataset. It can be defined as "A way of grouping the data points into different clusters, consisting of similar data points

K-means clustering is one of the simplest and popular unsupervised machine learning algorithms. ... In other words, the K-means algorithm identifies k number of centroids, and then allocates every data point to the nearest cluster, while keeping the centroids as small as possible.

You can think of an N-gram as the sequence of N words, by that notion, a 2-gram (or bigram) is a two-word sequence of words like “please turn”, “turn your”, or ”your homework”, and a 3-gram (or trigram) is a three-word sequence of words like “please turn your”, or “turn your homework”

In this episode ,I tried to explain the concept of Crypto Currenct based NFT

NFT:NFT (Non Fungible Token) are pieces of Digital content that are registered on the blockchain network and graphically represent underlying cryptocurrency that used to buy or register it.

NFT stands for non-fungible token, which basically means that it's a one-of-a-kind digital asset that belongs to you and you only.The most popular NFTs right now include artwork and music, but can also include videos and even tweetsNon Fungible Token:“Non-fungible” more or less means that it’s unique and can’t be replaced with something elseFungible  Token:Bitcoin and other cryptocurrencies are the most prominent uses of blockchain technology, and they're examples of fungible tokens.If you send somebody a Bitcoin and they send you one back, it doesn't have to be the same Bitcoin, just as with the ten-rupee note.

In this episode I narrate the story of recommendation system used by OTT Platforms, Social Medias and Video Platforms like YoutubeRecommendation SystemItem Based Filtering

Choice Based Recommendation

Netflix Recommendation Engine

Content Based Filtering

Collabaritive FilteringHow does OTT recommendation work?Custom recommendation system analyzes the past data history of a user and predicts the future insights that are more likely to engage the user.Cloud-based recommender systems help the OTT or VOD service providers in better understanding whether a service satisfies the user requirements or not.Which recommendation system next flix use?The Netflix Recommendation EngineTheir most successful algorithm, Netflix Recommendation Engine (NRE), is made up of algorithms which filter content based on each individual user profile.The engine filters over 3,000 titles at a time using 1,300 recommendation clusters based on user preferences.What is Content-based filtering?Content-based filtering uses item features to recommend other items similar to what the user likes, based on their previous actions or explicit feedback

In this episode I covered the fundamental of Natural language processing What is natural language processing?Natural language processing (NLP) is the ability of a computer program to understand human language as it is spoken and written -- referred to as natural language. It is a component of artificial intelligenceNLP consist of two things Data Pre Processing

Algorithm DevelopmentData PreProcessing:Data preprocessing involves preparing and "cleaning" text data for machines to be able to analyze itTokenization. This is when text is broken down into smaller units to work with.

Stop word removal. This is when common words are removed from text so unique words that offer the most information about the text remain.

Lemmatization and stemming. This is when words are reduced to their root forms to process.

Part-of-speech tagging. This is when words are marked based on the part-of speech they are -- such as nouns, verbs and adjectives.Listen the episode on all podcast platform and share your feedback as comments hereDo check the episode on various platformfollow me on instagram  https://www.instagram.com/podcasteramit

In This Episode I covered the following thingsBioMetrics : Biometrics is the measurement and statistical analysis of people's unique physical and behavioral characteristics. The technology is mainly used for identification and access control or for identifying individuals who are under surveillance.

Types

Algorithms 

Speech Reconition:Speech recognition is the capability of an electronic device or Machine to understand spoken words.

Face Recognition:Facial recognition is a way of identifying or confirming an individual's identity using their face

Retina/IRIS Recognition:Retina recognition is a biometric technique that uses the unique patterns on a person's retina for person identification

Gait Analysis:Gait recognition technology (GRT) can analyse the shape of an individual's body and the unique way in which that body moves when walking or running,

Finger Print:the verification of a person's identity by comparing their fingerprints with previously recorded samples, typically by means of a computerized system in which the person presses a finger against a sensor that scans a fingerprint.

Palm Print:Palm print recognition is a biometric authentication method based on the unique patterns of various characteristics in the palms of people's hands

ECG:An electrocardiogram records the electrical signals in your heart. It's a common and painless test used to quickly detect heart problems and monitor your heart's health. Electrocardiograms — also called ECGs or EKGs — are often done in a doctor's office, a clinic or a hospital room.

Signature Recognition:Signature recognition is an example of behavioral biometrics that identifies a person based on their handwriting
