Last updated on 26th Sep 2022, Blog, Interview Question
1. What’s Apache Mahout?
Ans:
Apache™ driver may be a library of scalable machine-learning algorithms, enforced on prime of Apache Hadoop® and victimizing the MapReduce paradigm. Machine learning may be a discipline of AI centered on sanctioning machines to be told while not being expressly programmed, and it’s ordinarily wont to improve future performance supported previous outcomes.
Once huge knowledge is hold on on the Hadoop Distributed filing system (HDFS), driver provides {the knowledge|the info|the information} science tools to mechanically notice pregnant patterns in those huge data sets. The Apache driver project aims to create it quicker and easier to show huge knowledge into huge data.
2. What will Apache driver do?
Ans:
Mahout supports four main knowledge science use cases:
Clustering: Takes things during a specific category (such as websites or newspaper articles) and organizes them into present teams, such things happiness to constant cluster square measure almost like one another.
Classification: learns from existing categorizations and so assigns unclassified things to the simplest class.
Frequent item-set mining: analyzes things during a cluster (e.g. things during a go-cart or terms during a question session) and so determine that things usually seem along
3. What’s the History of Apache Mahout? Once did it start?
Ans:
The driver project was started by many folks concerned within the Apache Lucene (open supply search) community with a full of life interest in machine learning and a need for sturdy, well-documented, scalable implementations of common machine-learning algorithms for cluster and categorization. The community was at first driven by weight unit et al.’s paper “Map-Reduce for Machine Learning on Multicore” (see Resources) however has since evolved to hide a lot of broader machine-learning approaches. driver additionally aims to:
