Google Summer of Code 2016 wrap-up: CloudCV

Google Open Source Blog - Mon, 02/06/2017 - 18:00
This guest post is part of our ongoing series of posts from the students, mentors and organization administrators who participated in Google Summer of Code (GSoC), a program which gets university students contributing to open source software.

Google Summer of Code 2016 was a memorable one for CloudCV. Despite being a relatively “young” organization (this is just our second year as a mentor organization), there were many excellent applicants who put a tremendous amount of effort into their proposals and ramp-up tasks. It was difficult to choose!

CloudCV began in the summer of 2014 as a research project within the Machine Learning and Perception Lab at Virginia Tech, with the ambitious goal of democratizing computer vision and machine learning. We’re run exclusively by students and are working to enable developers, researchers, and fellow students to leverage artificial intelligence technology as a service and to share state of the art algorithms with the research community.

In line with this goal, we decided to build two tools that cater to computer vision researchers and hobbyists alike: CloudCV-fy your code and CloudCV-IDE. Though building two new platforms from the ground up was going to be challenging, our students’ motivation was overwhelming and their performance surpassed all expectations. We even demonstrated their work at CVPR 2016, a top-tier computer vision conference!

CloudCV-fy

A recurring use case for computer vision researchers, and many others, is to build a web-based demo and REST API to demonstrate the capabilities of their creations to the world. But web development involves writing hundred of lines of additional code across multiple languages (HTML, CSS, JavaScript, etc), which takes time away from research.


Our first student, Ashish Chaudhary, took on this problem by building CloudCV-fy. Over many iterations of design and development, Ashish delivered a tool that allows a user to simply write lightweight wrappers around their machine learning model/library and be done. CloudCV-fy automatically builds web-based interactive demos for them -- no need to tinker with HTML, CSS or JavaScript. Code to demo. Done.

The demo can be hosted on our servers, the user’s own server or any third party cloud service. As a result of this, researchers can focus on what they do best: designing and training models. CloudCV handles the rest. You can learn more in the write-up Ashish did on his blog.

CloudCV-IDE

There has been an explosion in the number of deep learning frameworks and it is difficult for researchers to keep up with all the latest tools. CloudCV-IDE, built by student Gaurav Gupta, addresses this by allowing a user to build a deep learning network with a drag-and-drop interface, then export to the deep learning framework of their choice (Caffe, TensorFlow, etc).

Gaurav also added support to import model configuration files in order to visualize any architecture. This is one of the first attempts to do this.



By the end of the summer, Gaurav delivered a great UI to visualize models with robust support for Caffe and TensorFlow back-ends. This was a successful start that we plan to build on by supporting more frameworks and facilitating collaborative building of deep learning models.

Overall, this was a highly productive GSoC for CloudCV. Our tools are under active development and we welcome contributions and ideas for new features.

We will definitely apply for GSoC 2017. If you are a student interested in participating we encourage you to get involved early! Feel free to reach out to us on our Gitter channel or on our mailing list.

February 2017, “Community Choice” Project of the Month – Maxima

SourceForge.net: Front page news - Wed, 02/01/2017 - 06:27

For our February “Community Choice” Project of the Month, the community elected Maxima, a Computer Algebra System (CAS) written in Common Lisp.

Maxima is comparable to commercial systems like Mathematica and Maple as it is able to solve symbolic mathematical equations, be it in algebra, trigonometry, calculus, or others. It can calculate with exact integers and fractions, native floating-point and high-precision big floats.

Maxima is feature-filled and user-friendly, with an online manual, plotting commands, and numerical libraries. Users can write programs in its native programming language, and many have contributed useful packages in a variety of areas over the decades.

Maxima was previously chosen “Staff Pick” Project of the Month in November of 2015 and the Maxima team spoke about the project’s latest developments and direction. Recently we caught up with one of the developers of the project, Viktor Toth to find out how the project has been doing since then, and here’s what he had to say:

“We have had two or three maintenance releases since that date. Our goal at this point is to continue offering support for Maxima, fix bugs, maintain compatibility with as many platforms as possible, and create stable installation packages. Changes to Maxima at this point tend to be relatively minor and incremental, including, for instance, corrections and improvements to the documentation and its translations.”

Maxima continues to be widely-used with over 300,000 direct downloads annually, and also continues to receive positive feedback from users.

Dojo 2 updates – Week ending Jan. 27, 2017

The Dojo Toolkit - Announcements - Tue, 01/31/2017 - 13:54

Over the past few weeks, we’ve been working on several large improvements to widget authoring and theming with Dojo 2.

Theming

We’re currently using css-modules and css-next via PostCSS, a powerful tool for transforming CSS with JavaScript. css-next enables us to just write vanilla CSS with vendor prefixing done automatically, so there’s no need to learn the separate syntax of a CSS pre-processor such as SASS, LESS, or Stylus, just the new semantics of CSS.

This gives us several primary benefits for how themes are applied to widgets within Dojo 2:

  • Local scoping by default and obfuscated class names prevent class name collisions across widgets and from top level CSS rules
  • Full autocomplete/Intellisense for widget authoring, which extends to how CSS class names are specified. Only the locally scoped widget class names are available, which is very powerful
  • Users can import fully supported Dojo 2 theme variables into their custom widgets
  • CSS authoring is fully built into the Dojo 2 cli

Overall we believe this will provide a complete end-to-end authoring experience that makes theming much easier for TypeScript developers.

This work has either landed in master or is currently under review as PRs.

Simplifying widget state and property handling

Via our widget API, we promote the reactive principles of “properties in, events out”. By default, Dojo 2 widgets are stateless. Widgets are passed properties and implement a render function. Through refactoring to reduce and simplify the surface area of widgets, we have removed state from the widget API. This simplifies the authoring experience of widgets, leaving us with a very simple public API for widgets: `render` and `diffProperties`. Both functions have sensible default implementations.

We also provide capabilities for more advanced widget authoring, such as diff-ing single properties if needed, and adding behavioral traits via functional composition.

Usage of Dojo 2 widgets is documented in the widget-core readme.

Web components

Beyond our usage of Custom Elements for all Dojo 2 widgets, we have been working on support for making any Dojo 2 widget easy to export as a web component to use within other environments that support web components. While a web component will not have all of the benefits of using a widget inside a Dojo 2 environment, this will make it much easier to include a Dojo 2 widget within a non-Dojo application. For example, say you want to make dgrid available for use in non-Dojo applications? This will now be much easier to do with Dojo 2 widgets.

Initial support for web component utilities landed recently in widget-core. Support for exporting a single widget as a web component, and installing via npm, is currently under development.

Dojo 2 roadmap

As January draws to a close, we’re continuing updates on the Dojo 2 roadmap.

Introducing Draco: compression for 3D graphics

Google Open Source Blog - Mon, 01/30/2017 - 23:00
3D graphics are a fundamental part of many applications, including gaming, design and data visualization. As graphics processors and creation tools continue to improve, larger and more complex 3D models will become commonplace and help fuel new applications in immersive virtual reality (VR) and augmented reality (AR).  Because of this increased model complexity, storage and bandwidth requirements are forced to keep pace with the explosion of 3D data.

The Chrome Media team has created Draco, an open source compression library to improve the storage and transmission of 3D graphics. Draco can be used to compress meshes and point-cloud data. It also supports compressing points, connectivity information, texture coordinates, color information, normals and any other generic attributes associated with geometry.

With Draco, applications using 3D graphics can be significantly smaller without compromising visual fidelity. For users this means apps can now be downloaded faster, 3D graphics in the browser can load quicker, and VR and AR scenes can now be transmitted with a fraction of the bandwidth, rendered quickly and look fantastic.


Sample Draco compression ratios and encode/decode performance*
Transmitting 3D graphics for web-based applications is significantly faster using Draco’s JavaScript decoder, which can be tied to a 3D web viewer. The following video shows how efficient transmitting and decoding 3D objects in the browser can be - even over poor network connections.


Public domain Discobolus model from SMK National Gallery of Denmark.

Video and audio compression have shaped the internet over the past 10 years with streaming video and music on demand. With the emergence of VR and AR, on the web and on mobile (and the increasing proliferation of sensors like LIDAR) we will soon be swimming in a sea of geometric data. Compression technologies, like Draco, will play a critical role in ensuring these experiences are fast and accessible to anyone with an internet connection. More exciting developments are in store for Draco, including support for creating multiple levels of detail from a single model to further improve the speed of loading meshes.

We look forward to seeing what people do with Draco now that it's open source. Check out the code on GitHub and let us know what you think. Also available is a JavaScript decoder with examples on how to incorporate Draco into the three.js 3D viewer.

Google Summer of Code 2016 wrap-up: GitHub

Google Open Source Blog - Mon, 01/30/2017 - 21:45
Every year open source organizations, mentors, and university students come together to build and improve open source software through Google Summer of Code (GSoC). This guest post is part of a series of blog posts from people who participated in GSoC 2016.

GitHub-Mark-120px-plus.png

Open source maintainers at GitHub mentored 5 students in Google Summer of Code last year. The students did great work that we’d like to highlight and congratulate them on:
Updates to GitHub Classroom GitHub Classroom helps teachers automate their work and interact with students in issues and pull requests. Last summer two students took on projects to help teachers work more efficiently and with greater insight into their classrooms.
Classroom Project #1 Cheng-Yu Hsu is a student who worked to implement new features suggested by teachers using GitHub Classroom, including due dates for assignment submissions and visualizations of classroom activities. In reflecting on the project, Cheng-Yu said:

"Having a great community is one of the most important factors of a successful open source project, so participating [in] the community is also a huge part of this project. It is great to have chances responding to user feedback, helping people resolve issues and brainstorming new features with them."
Classroom Project #2Shawn Ding worked on student identifiers and team management for GitHub Classroom. This means that teachers using GitHub Classroom can use things such as student emails to identify their assignments. Teachers can also now manage their students and teams of students using GitHub Classroom via drag and drop in the settings page which then updates the data on GitHub.
Front-end controls for JekyllJekyll Admin is a Jekyll plugin that provides users with a traditional CMS-like graphical interface to author content and administer Jekyll sites from the comfort of their browser. GSoC student Mert Kahyaoğlu has been using Facebook’s React framework to create the front-end that will allow you to write a new post, edit existing pages or add new files. And it will all work with GitHub Pages.

Best of all, Mert's plugin allows people to author content and administer Jekyll sites without knowledge of command line or installing an external text editor like Atom. Once installed, Jekyll users start their site as they would normally and simply append “/admin” to their site's URL to launch the WordPress-like administrative interface. Jekyll Admin's initial release is ready for use on your own site.
Octokit.net Alexander Efremov added support to Octokit.net for interacting with the GitHub API using a repository ID, alongside the existing support for providing the owner and repository name. This means integrators do not have to update their systems when a repository changes ownership. The changes to support these APIs were rolled out incrementally over a number of pull requests, and 0.21 release of Octokit.net made these new APIs available to the public.

We had a great time mentoring these students on their projects last year!

Google Summer of Code 2016 wrap-up: Orange

Google Open Source Blog - Mon, 01/30/2017 - 21:36
This post is part of our ongoing series of guest posts from the students, mentors and organization administrators who participated in Google Summer of Code (GSoC). GSoC is a program that pairs university students with mentors for a summer where they apply their computer science skills to building open source software.


Orange Data Mining is a data mining suite with visual programming and interactive data analysis at its core. Orange was developed at Bioinformatics Lab at University of Ljubljana, Slovenia, it is written mainly in Python, and you can find it hosted on GitHub.

This was our third Google Summer of Code and we were given five slots and decided to select students based on two criteria: their proposal joined with their coding skills and the importance of the project to our organization.

Great work was done over the summer and we are proud to present our students’ projects!

Recommender Systems add-on by Salva Carrion

Salva independently implemented a new Orange3 add-on for recommender systems. He developed a scripting library for collaborative filtering for the core of the add-on, which includes a number of published matrix factorization algorithms. The scripting library is then further extended to include GUI-based widgets for visual programming.

Educational add-on by Primož Godec

Primož took on a task of developing a series of educational widgets for Orange3. The end result was a full Orange3-Educational add-on with four widgets that can be used to demonstrate key data mining and machine learning procedures in the classroom. These widgets are useful for helping beginners understand the inner workings of key algorithms in data mining, and for teachers to be able to visually explain the various methods. They include interactive and step-by-step visualizations of k-means, polynomial classification, and gradient descent.



Text add-on by Aliaxey Sukharevich

Orange3-Text add-on was already an active project before GSoC, but Aliaxey took it to another level. Twitter and Wikipedia public RESTful services were introduced as widgets to allow acquisition of data from new sources. Many widgets were boosted with new functionalities and methods (e.g. HDP, LDA and LSP methods in Topic Modelling widget). Preprocessing was redesigned and reimplemented such that it now handles n-grams and POS Tagging.



CN2 Rule Induction by Matevž Kren

The goal of this project was to implement a CN2 rule induction algorithm, and Orange widgets for learning and exploration of inferred classification rules. At the heart of the project is an implementation of a scripting library, which can be easily extended with additional divide and conquer algorithms or its components.

Porting Orange codebase to Pandas by Sašo Stanovnik

This was a gargantuan task and Sašo handled it beautifully. The goal was to consolidate Orange data structures and management routines to support data from Pandas. Sašo redesigned Orange data management core, did a massive amount of refactoring and improvements and removed legacy and unused code. The biggest challenge was of course preserving as much compatibility with the existing Orange interaction as possible while providing full Pandas flexibility. The result is a functional Pandas-based core Orange.

All contributions were committed on GitHub (Orange3, Orange3-Text, Orange3-Recommendation and Orange3-Educational repositories) and most of them are already pip-installable. The only contribution that has not yet been merged is the migration to Pandas, which will require adaptation and careful compatibility checking of other components of the system.

We are extremely grateful to be given the chance to participate in Google Summer of Code and to have had such amazing students at our lab. We can’t wait to apply again next year!

The Google Open Source Programs Office is proud to run this contest each year. The quality of work from our participating students is incredible, and each year we look forward to meeting our Grand Prize winners in person. It’s exciting to see the next generation of coders emerge! We also owe a huge debt of gratitude to all of the mentors who helped guide each of the participants through their tasks. Without their tireless work over the past 7 weeks, GCI would not be possible.

Stay tuned to the open source blog - we’ll regularly post Google Code-in 2016 stories in the upcoming months including a full breakdown of contest statistics, wrap-up posts from the organizations, student highlights and more.
