H2O - Introduction
Have you ever been asked to develop a Machine Learning model on a huge database? Typically, the customer will provide you the database and ask you to make certain predictions such as who will be the potential buyers; if there can be an early detection of fraudulent cases, etc. To answer these questions, your task would be to develop a Machine Learning algorithm that would provide an answer to the customer’s query. Developing a Machine Learning algorithm from scratch is not an easy task and why should you do this when there are several ready-to-use Machine Learning libraries available in the market.
These days, you would rather use these libraries, apply a well-tested algorithm from these libraries and look at its performance. If the performance were not within acceptable limits, you would try to either fine-tune the current algorithm or try an altogether different one.
Likewise, you may try multiple algorithms on the same dataset and then pick up the best one that satisfactorily meets the customer’s requirements. This is where H2O comes to your rescue. It is an open source Machine Learning framework with full-tested implementations of several widely-accepted ML algorithms. You just have to pick up the algorithm from its huge repository and apply it to your dataset. It contains the most widely used statistical and ML algorithms.
To mention a few here it includes gradient boosted machines (GBM), generalized linear model (GLM), deep learning and many more. Not only that it also supports AutoML functionality that will rank the performance of different algorithms on your dataset, thus reducing your efforts of finding the best performing model. H2O is used worldwide by more than 18000 organizations and interfaces well with R and Python for your ease of development. It is an in-memory platform that provides superb performance.
In this tutorial, you will first learn to install the H2O on your machine with both Python and R options. We will understand how to use this in the command line so that you understand its working line-wise. If you are a Python lover, you may use Jupyter or any other IDE of your choice for developing H2O applications. If you prefer R, you may use RStudio for development.
In this tutorial, we will consider an example to understand how to go about working with H2O. We will also learn how to change the algorithm in your program code and compare its performance with the earlier one. The H2O also provides a web-based tool to test the different algorithms on your dataset. This is called Flow.
The tutorial will introduce you to the use of Flow. Alongside, we will discuss the use of AutoML that will identify the best performing algorithm on your dataset. Are you not excited to learn H2O? Keep reading!
