  1. Data Science Studio (DSS) 

It is a powerful tool designed to connect technology, business and data. It is available in two segments: Coding & Non-Coding. It’s a complete package for any organization which aims to develop, build, deploy and scale models on network. DSS is also powerful enough to create smart data applications to solve real world problems. It comprises of features which facilitates team integration on projects. Among all features, the most interesting part is that work can be reproduced in DSS as every action in the system is versioned through an integrated GIT repository.

12. OpenRefine 

It started as Google Refine but looks like google plummeted this project due to unclear reasons. However, this tool is still available renamed as Open Refine. Among the generous list of open source tools, openrefine specializes in data cleaning, transforming and shaping it for predictive modeling purposes. As an interesting fact, during model building, 80% time of an analyst is spent in data cleaning. Not so pleasant, but it’s the fact. Using openrefine, analysts can not only save their time, but also put it to use for productive work.

  1. Talend 

Decision making these days is largely driven by data. Managers & professionals no longer make gut-based decision. They require a tool which can help them quickly. Talend can help them to explore data and support their decision making. Precisely, it’s a data collaboration tool capable of clean, transform and visualize data. Moreover, it also offers an interesting automation feature where a person can save and redo their previous task on a new data set. This feature is unique and hasn’t been found in many tools.
