Which is better WEKA or python?

What language does WEKA use?

Java
Weka is a collection of machine learning algorithms for solving real-world data mining problems. It is written in Java and runs on almost any platform. The algorithms can either be applied directly to a dataset or called from your own Java code [5].

Is Weka good for machine learning?

Weka Machine Learning Algorithms. Weka has a lot of machine learning algorithms. This is great, it is one of the large benefits of using Weka as a platform for machine learning. A down side is that it can be a little overwhelming to know which algorithms to use, and when.

Should I learn Weka?

Weka is a great place to start exploring machine learning because you can implement common algorithms without writing any code. You can also grow your skills with Weka to use different and more advanced methods. Some additional algorithms you can use for classification are C4.

Can Weka process big data?

A common misconception is that the Weka machine learning software cannot be applied to large datasets. When considering large datasets, it is important to distinguish between training of machine learning models and deploying such models for prediction. Weka is being used to make predictions in real time in very demanding real-world applications. This can be done with almost all Weka models once they have been trained.

What are the best tools for data mining?

The most prevalent tool used in data mining is the process called Knowledge Discovery in Databases (KDD). KDD was developed in 1989 by Gregory Piatetsky-Shapiro. Using this data mining tool, users are able to process raw data, mine the data for information and interpret the various results in the form of information management.

Is Weka used a lot in the industry?

Overall: Weka is one of the main tools used for data mining .Weka provides large number of data mining algorithms for the users which helps the users to try any type of data mining technique through one software product. Also it provides data preprocessing facility which helps to format the data set.
