Recommendation Engines - Know How

Recommendation Engines perform a variety of tasks - but the most important one is to find products that are most relevant to the user. Content based filtering, collaborative filtering and Association rules are common approaches to do so.

So let's first Understand basics of Recommendation Engines and then we'll later on Build Our Own Recommendation Engine !!!

HIGH QUALITY, PERSONALIZED ARE THE HOLY GRAIL FOR EVERY ONLINE STORE.
UNLIKE OFFLINE STORES, ONLINE STORES HAVE NO SALES PEOPLE.
USERS ON THE OTHER HAND HAVE LIMITED TIME AND PATIENCE, ARE NOT SURE WHAT THEY ARE LOOKING FOR ONLINE STORES HAVE A HUGE NUMBER OF PRODUCTS.
RECOMMENDATIONS HELP USERS NAVIGATE THE MAZE OF ONLINE STORES FIND WHAT THEY ARE LOOKING FOR FIND THINGS THEY MIGHT LIKE, BUT DIDN’T KNOW OF.
RECOMMENDATIONS HELP ONLINE STORES SOLVE THE PROBLEM OF DISCOVERY.
BUT HOW? Lets Explain this.

ONLINE STORES HAVE DATA
1) WHAT USERS BOUGHT
2) WHAT USERS BROWSED
3) WHAT USERS CLICKED
4) WHAT USERS RATED

All these DATA IS FED into Recommendation Engine to derive below:
TOP PICKS FOR YOU!!
IF YOU LIKE THIS, YOU’LL LOVE THAT!
IF YOU BUY THIS, YOU’LL NEED THAT!



Tasks Performed by Recommendation Engine

Filter Relevant Products

Sub Tasks: 1.1) PREDICT WHAT RATING THE USER WOULD GIVE A PRODUCT
1.2) PREDICT WHETHER A USER WOULD BUY A PRODUCT
1.3) RANK PRODUCTS BASED ON THEIR RELEVANCE TO THE USER

HOW TO FIND RELEVANT PRODUCTS
1) “SIMILAR” TO THE ONES THE USER “LIKED” (Content Based Filtering)
2) “LIKED”BY “SIMILAR” USERS (Collaborative Filtering)
3) PURCHASED ALONG WITH THE ONES THE USER “LIKED” (Association Rules)

RECOMMENDATION ENGINES NORMALLY USE ONE OR MORE OF THESE TECHNIQUES.

BEFORE WE GO AHEAD, LET’S JUST CLARIFY -
HOW DO WE KNOW THAT A USER “LIKES” A PRODUCT?
Ans) THESE ARE PRODUCTS THE USER
              PURCHASED
              CLICKED ON
              ADDED TO CART
              RATED HIGHLY
(IF THE USER RATES SOMETHING LOW, THAT’S IMPORTANT DATA TOO!)
SOMETIMES, STORES ALSO ASK FOR EXPLICIT INPUT FROM USERS.

Basics Of Hadoop Ecosystem - 2

Basics of Hadoop Ecosystem – 2 Apache Ambari is a web-based tool for provisioning, managing, and monitoring Apache Hadoop clusters. It has a very simple yet highly interactive UI to install various tools and perform various management, configuration and monitoring tasks.  Introduction: In part 2 of the blog series I will cover the other core components of a Hadoop Framework including querying part, external integration, data exchange, co-ordination and managing as well as monitoring of Hadoop Clusters. Please refer to Basic’s of Hadoop Ecosystem  Part 1 ... QUERYING: Pig seems quite useful however; I am more of an SQL person. For those of us who still like SQL, we have SQL for Hadoop. HIVE Hive is a distributed data warehouse built on atop of HDFS to manage and organize large amounts of data. It provides a query based on SQL semantics  (HiveQL)  which is translated by the runtime engine to Map Reduce jobs for querying the data. Sche...

Data Engineering - Tools & Intro

Data Engineering - Tools & Intro So I just realized that I am here after a month or so. I was busy at work and traveling. I am starting a kind of new series, I say it Data Engineering Series in which I will be discussing different tools. Of course, I am not able to discuss the entire concept of Data Engineering neither I know it as I will be learning myself. What is Data Engineering? Data Engineering is all about developing, maintaining systems that are responsible for transferring data in large volumes and make it available for analysts and data scientists to use it for analyzing and data modeling. Data engineering is a superset of Data Science or the subset, not clear to me but the collaboration of data engineers and scientists fruits useful data-driven solutions. Data Engineering tools It consists of several tools. Some are dealing with data storage while others with analysis and ETL. Ofcourse, Apache Kafka is one of them. The others tools that I might be covering are Apache...

Differences Between Hibernate and Spring Data JPA?

Differences Between Hibernate and Spring Data JPA? In this quick article, I would like to describe what is the difference between  Hibernate ORM framework  and  Spring Data JPA . Let's first know the definition of  JPA ,  Hibernate , and  Spring Data JPA , so this will make it easy to discuss the difference between Hibernate and Spring Data JPA. What Is Java Persistence API? The Java Persistence API provides a specification for persisting, reading, and managing data from your Java object to relational tables in the database. Read more about JPA at  JPA Tutorial - Java Persistence API  (you will learn everything about JPA here). What Is Hibernate Framework? Hibernate is an object-relational mapping solution for Java environments. Object-relational mapping or ORM is the programming technique to map application domain model objects to the relational database tables. Hibernate is a Java-based ORM tool that provides a framework for ma...
