Support NumFOCUS during our 2021 Year-End Fundraiser!

This is the second in our blog series about the 2019 NumFOCUS Google Summer of Code students. (Part 1, Part 3)

We are excited to introduce to the community our cohort of GSoC students working with some of our NumFOCUS Affiliated Projects: ArviZ, Chainer, CuPy, Data Retriever, MDAnalysis, QuTiP, and YellowBrick.

GSoC with ArviZ

ArviZ is a Python package for exploratory analysis of Bayesian models. Includes functions for posterior analysis, sample diagnostics, model checking, and comparison.

Oriol Abril Pla

Oriol Abril Pla is an Astrophysics student in the Masters degree program at Autonomous University of Barcelona. His hometown is Sant Cugat del Vallès, Barcelona, Spain. This is his second time participating in GSoC with NumFOCUS!

Oriol’s project is Information criteria and convergence assessment tools for ArviZ:

ArviZ […] still lacks plots and tools to ease and improve its interpretation. This project seeks to design and implement these tools. Moreover, it will pay special attention to testing and documentation with examples not only of the new functionalities, but also of the already implemented ones.

Learn more about his progress on his GSoC student blog.

What motivated you to apply for GSoC with ArviZ?
I am really interested in Bayesian modelling and I came across ArviZ some time ago, I actually started contributing before knowing GSoC existed. Some time later I discovered GSoC and realized it was compatible with my Master. Being able to dedicate myself full time to such an interesting project was like a match made in heaven.

Why did you choose your specific project topic?
I have been deeply involved throughout my Bachelor and Master and I ended up switching to Bayesian inference when models became more complicated and data scarce. However, I felt that I lacked some tools for assessing the “goodness” of my inferences, which is a subject really interesting to me. ArviZ provided them to some extent, but they wanted to expand their capabilities in this topic.

How did you get involved in open source software?
I got involved in open source software during my Bachelor thesis, which involved novae simulations with MESA. At the time, the project was really new, and new contributions were really encouraged, so I started submitting some issues to MESAplot, and ended up making public a small repository to add syntax highlight for MESA files in vim.

What are you expecting or hoping to get out of your GSoC experience?
I expect to get a great experience at many levels. I expect to meet many interesting people and become part of the community, to learn a huge deal of Bayesian methods (which I already have before the start of the coding period) and to deepen my programming knowledge and extend the libraries I am comfortable with.

What are your career goals? How do you see the GSoC program moving you towards them?
I would like to work at the boundary between data science, modelling and astrophysics, so everything I learn during this summer will for sure be a great asset afterwards to help with my career.

“I would like to reach out to anybody who is unsure about contributing to open source software to contact the project they are interested in and see how can you help. Do not worry about not knowing enough, once they have time (bear in mind that many projects are maintained by volunteers) they will most surely reply and guide you.”

This project aims at extending ChainerX capability for common numerical linear algebra routines.

Learn more about his progress on his GSoC student blog.

What motivated you to apply for GSoC with Chainer?
GSoC is a wonderful opportunity to become involved in open-source development and learn the internals of interesting projects.

Why did you choose your specific project topic?
Numerical Linear Algebra routines such as in `numpy.linalg` form the basis for many algorithms in scientific computing. Making them available and make them differentiable in ChainerX would benefit not only Deep Learning practitioners but also attract non-DL users as well. For me personally, it means improving my skills in C++ programming and learning how to integrate external libraries with ChainerX.

How did you get involved in open source software?
Two years ago I participated in GSoC with FEniCS Project.

What are you expecting or hoping to get out of your GSoC experience?
ChainerX is a young project for nd-array and automatic differentiation in C++. I would like to take part in the early development of the library and help to convert a Python-based Deep Learning framework into a C++ one. I am looking forward to building relationships with ChainerX developers in Japan, that would be an invaluable experience for me.

What are your career goals? How do you see the GSoC program moving you towards them?
I’ve recently started PhD in inverse problems. So my goals are concentrated around building interesting and successful research. Differentiating numerical simulations is crucial in tasks like optimization and statistical inference. I will greatly benefit from the experience of extending ChainerX with calls to external programs and libraries for coupling numerical simulator with automatic differentiation.

Akshay Subramanian

Akshay Subramanian is a Materials Science and Engineering student in the Bachelors degree program at Indian Institute of Technology Roorkee. His hometown is Bangalore, Karnataka, India. This is his first time participating in GSoC.

Akshay’s project is Expand ChainerX Ops:

ChainerX is the next generation of the Chainer framework completely based in C++. It must therefore possess support for all Chainer routines and other important routines that have for instance, been defined in NumPy and SciPy. The project Expand ChainerX Ops aims to bridge this gap in routine definitions by implementation of the operations to ChainerX.

Learn more about his progress on his GSoC student blog.

What motivated you to apply for GSoC with Chainer?
My interest lies mostly in the fields of deep learning and machine learning and their applications in science and mathematics. The organizations under NumFOCUS had projects which aligned with my interests.

Why did you choose your specific project topic?
I chose the project topic which I had most confidence in completing and which I felt had the steepest learning curve.

How did you get involved in open source software?
Other open source projects have been extremely helpful to me in the past. I felt that contributing to open source is probably the easiest way to help millions of people around the world while working from home.

What are you expecting or hoping to get out of your GSoC experience?
I hope the project I have chosen has a steep learning curve. Apart from this, I hope to learn to maintain world class software products and help others get easily acquainted with open source just as I could.
