What is Apache Mahout?

Apache Mahout is a powerful project of the Apache Software Foundation that leverages big data computation through Hadoop and MapReduce. It is a machine-learning software library written in Java. It builds scalable clustering, classification, and collaborative filtering algorithms.

You can create algorithms for clustering, classification, and collaborative filtering with Mahout. Mahout also includes many built-in algorithms that you can use right away.

Why should you use it?

• Mahout uses various techniques, such as ML and data mining algorithms, to create complex predictive models.
• It uses several underlying algorithms, such as Random Forest, H2O, and SVD++, to build customized models for your input data.
• Its flexible architecture allows you to add or customize new algorithms easily.
• Mahout also provides many powerful APIs that make it easy to work with large datasets, run complex algorithms, and integrate machine learning into your applications.

Mahout Workflow

• Start by training a model using your input data and the algorithms of your choice.
• Once you have a trained model, use it to predict new data.
• You can then use these predicted values to build more complex models or incorporate them into your application as desired.

Features

Supports several ML algorithms

Mahout is an open-source machine-learning library that supports several machine-learning algorithms for clustering, classification, regression, and collaborative filtering.

Data preprocessing

Mahout’s key features include its ability to perform feature selection and dimensionality reduction as part of the data preprocessing step before running machine learning algorithms on the data.

Clustering approach

Another key feature is its ability to cluster similar documents based on their text content using various clustering approaches such as k-means or hierarchical clustering algorithms.

Classification and regression

Mahout also offers support for performing supervised learning tasks such as classification and regression, which can be used to predict future outcomes based on historical data.

Collaborative filtering and recommender

It also supports a range of unsupervised learning techniques, such as 

• Collaborative filtering for building recommendation engines.    
• Recommender systems to recommend relevant products for users based on their interests and preferences.

Tools for analyzing large datasets

Mahout includes several tools for analyzing large datasets using distributed computing frameworks like Apache Spark or Hadoop MapReduce, which makes it well suited for working with big data applications and processing large volumes of data at scale.

Pros

• User-friendly interface.
• Using Mahout, we can easily analyze any Hadoop file system data directly from the file system because Mahout sits on top of Hadoop systems.
• Using this software, you can deploy large-scale learning algorithms.
• In the event of failure, it provides fault tolerance.
• You can use Mahout to perform data preprocessing tasks, such as determining feature importance, finding outliers and correlations, or detecting anomalies.

Cons

• Its computing time is relatively slow compared to other frameworks such as MLlib and TensorFlow.
• As an open-source framework, it does not offer enterprise support.

Applications
