Introducing Datalore - an intelligent web application for machine learning

This Monday, February the 12th, we launched a public beta of Datalore - an intelligent web application for data analysis and visualization in Python, brought to you by JetBrains. This tool turns the data science workflow into a delightful experience with the help of smart coding assistance, incremental computations, and built-in tools for machine learning.

Intelligent code editor

Data science is an art of drawing insights from the raw data, and to make good predictions, you need to write code. To make machine learning-specific coding an enjoyable and easy experience, Datalore provides smart code completion, inspections, quick-fixes, and easy navigation.

To make your coding routine easier, we introduce Intentions - context-aware suggestions that appear depending on what you’ve just written. Click on the appropriate Intention, and Datalore will generate new code for dataset upload, train/test split, graph design, and much more.

Incremental computations

Fine-tuning machine learning models comes with multiple edits. Suppose you adjust a few model parameters and want to see how it affects its predictions - and you want these results right now. Datalore follows dependencies between various computations in the workbook and minimizes recalculations caused by new changes. This way, the output at the right side of the screen always reflects your latest ideas.

Machine learning tools

Data analysis starts with Python necessities: numpy, pandas, and sklearn built-in libraries. On top of that, we developed two advanced visualization libraries: datalore.plot, inspired by the "grammar of graphics" ideas and their R implementation ggplot, and a datalore.geo_maps which enables the addition of interactive maps to your analysis. There are built-in datasets (Iris, MNIST, Titanic, and more) for beginners to explore or a handy File Manager to upload original datasets as .csv-files.

Collaboration

We also enable real-time remote access to the workbook and code editor. To show your model to colleagues and get their insights, just share the workbook link. Team members can edit and add code on the go while discussing ideas.

Different computational instances

Datalore allows access to various computational resources depending on what task you are working with. Simple algorithms run on small computational agents, while deep learning algorithms require more powerful agents. Contact us via our forum if you want to work with larger instances.
