Orange is Getting Smarter

In the past few months, Orange has been getting smarter and sleeker. Since version 3.15.0, Orange remembers which distinct widgets users like to connect, adjusting the sorting on the widget search menu accordingly. Additionally, there is a new look for the Edit Links window coming soon. Orange recently implemented a basic form of opt-in usage tracking, specifically targeting how users add widgets to the canvas. Word cloud of widget popularity in Orange.

Explaining Kickstarter Success

On Kickstarter most app ideas don’t get funded. But why is that? When we are looking for possible explanations, it is easy to ascribe the failure to the type of the idea. But what about those rare cases, where an app idea gets funded? Can we figure out why a particular idea succeeded? Our new widget Explain Predictions can do just that - explain why they will succeed. Or at least, explain why the classifier thinks they will.

From Surveys to Orange

Today we have finished a series of workshops for the Ministry of Public Affairs. This was a year-long cooperation and we had many students asking many different questions. There was however one that we talked about a lot. If I have a survey, how do I get it into Orange? Related: Analyzing Surveys We are using EnKlik Anketa service, which is a great Slovenian product offering a wide array of options for the creation of surveys.

'Python Script: Managing Data on the Fly'

Python Script is this mysterious widget most people don’t know how to use, even those versed in Python. Python Script is the widget that supplements Orange functionalities with (almost) everything that Python can offer. And it’s time we unveil some of its functionalities with a simple example. Example: Batch Transform the Data There might be a time when you need to apply a function to all your attributes. Say you wish to log-transform their values, as it is common in gene expression data.

Unfreezing Orange

Have you ever tried Orange with data big enough that some widgets ran for more than a second? Then you have seen it: Orange froze. While the widget was processing, the interface would not respond to any inputs, and there was no way to stop that widget. Not all the widgets freeze, though! Some widgets, like Test & Score, k-Means, or Image Embedding, do not block. While they are working, we are free to build other parts of the workflow, and these widgets also show their progress.

Single cell analytics workshop at HHMI | Janelia

HHMI | Janelia is one of the prettiest researcher campuses I have ever visited. Located in Ashburn, VA, about 20 minutes from Washington Dulles airport, it is conveniently located yet, in a way, secluded from the buzz of the capital. We adored the guest house with a view of the lake, tasty Janelia-style breakfast (hash-browns with two eggs and sausage, plus a bagel with cream cheese) in the on-campus pub, beautifully-designed interiors to foster collaborations and interactions, and late-evening discussions in the in-house pub.

Neural Network is Back!

We know you’ve missed it. We’ve been getting many requests to bring back Neural Network widget, but we also had many reservations about it. Neural networks are powerful and great, but to do them right is not straight-forward. And to do them right in the context of a GUI-based visual programming tool like Orange is a twisted double helix of a roller coaster. Do we make each layer a widget and then stack them?

Analyzing Surveys

Our streak of workshops continues. This time we taught professionals from public administration how they can leverage data analytics and machine learning to retrieve interesting information from surveys. Thanks to the Ministry of Public Administration, this is only the first in a line of workshops on data science we are preparing for public sector employees. For this purpose, we have designed EnKlik Anketa widget, which you can find in Prototypes add-on.
