A Handy Little Tool to aid your Data Science projects

A productivity tool for data science operations to make doing data science simpler and faster, especially for the domain-erudite audience. Created by Ramshankar Yadhunath and Srivenkata Srikanth, with the help of Arvind Sudheer.

DSK is primarily software that has been built with the purpose of aiding anybody who is familiar with necessary domain expertise to do preliminary data science. It works as a handy productivity tool, making preliminary data science operations both simpler as well as faster.

DSK lets users load a raw block of tabular data onto it and asks relevant questions about the kind of operations the user wants to do with the data. DSK then performs these operations of data cleaning, pre-processing, auto-generating visualizations and even some preliminary baseline modelling, all based on the user's response to the questions asked. DSK only makes use of these question-response interactions with the user and thus helps users perform preliminary data science without having to write any code to do so.

The diagram below represents the overall high-level functionality of DSK.

All questions asked by DSK are ones that require single-character or single-word responses. These include Multiple Choice Questions, Yes/No Questions and Single-Word Answer Questions.

DSK currently runs only on the command line.

Speed and Convenience are two very important considerations for any data science project. Often, the preliminary part of it i.e organizing the project, data cleaning and pre-processing takes up a considerable amount of time, especially if code has to be written for every minor operation that needs to be performed. If data science has to be made simpler and easier for quickly generating essential results(without having to write code), full or partial control has to be transferred from the hands of the user to the system itself. In other words, the system has to be automated.

DSK is an attempt at laying the foundations for a system that will work in automated fashion to help users perform preliminary data science operations without writing code. Currently, DSK is prototypical and will be scaled to a full product in the future iterations of this project.

DSK has also been created by keeping in the best interests of the research community in mind. Students and researchers from fund-crunched institutes usually cannot afford proprietary tools to help with their research. The non-data technicals, i.e people who are running small businesses are usually discouraged from tapping into data-driven techniques because most tools require an early investment of time and money. The free blogs and articles that talk about data science in general can't convince these businesses. The owners do not know how effectively they could use the data they have. DSK helps bridge this gap. Moreover, DSK is free to use and hence can be of help to anybody who wishes to utilize it.

The explanation of data flow through DSK has been moved here. Head over to this link in order to understand how DSK helps an end user. Screenshots of the working have been included.
