Introducing the Dev Library Contributor Spotlights – a weblog sequence highlighting builders which can be supporting the thriving improvement ecosystem by contributing their sources and instruments to Google Dev Library.
We met with Doug Duhaime, Full Stack Developer in Yale College’s Digital Humanities Lab, to debate his ardour for Machine Studying, his processes and what impressed him to launch his PixPlot mission as an Open Supply.
What led you to discover the sector of machine studying?
I used to be an English main in undergrad and in graduate faculty. I’ve a PhD in English literature. My dissertation was exploring copyright historical past and the ways in which modifications in copyright legislation affected the e book market. How does the establishment of mounted period copyright affect the e book market? To reply this query, I needed to mine an infinite assortment of knowledge – half one million books, printed earlier than 1800 – to have a look at totally different patterns. That was one of many key initiatives that obtained me impressed to additional discover the world of Machine Studying.
In actual fact, one among my initiatives – the PixPlot library – makes use of pc imaginative and prescient to research picture collections, which was additionally partially utilized in my analysis. A part of my analysis checked out plagiarism detection and the way readily individuals are inclined to repeat photos as soon as it turns into authorized to repeat them from different texts. Laptop imaginative and prescient helps us to reply these questions and determine key patterns.
I’ve seen machine studying and programming as a approach to ask new questions in historic contexts. And there is a entire subject of us – we’re referred to as digital humanists. Yale College, the place I have been for the final 5 years, has a incredible digital humanities program the place researchers are asking questions like this and utilizing enjoyable machine studying platforms like TensorFlow to reply these questions.

Are you able to inform us extra in regards to the evolution of your PixPlot library mission?
We began in Yale’s digital humanities lab with a mission referred to as neural neighbors. And the thought right here was to seek out patterns within the Meserve-Kunhardt Assortment of photos.
Meserve-Kunhardt is a set of pictures largely from the nineteenth century that Yale not too long ago acquired. After being acquired by the college, some curators had been getting ready to determine all this actually wealthy metadata to explain these photos. Nevertheless, that they had a backlog, they usually wanted assist to attempt to make sense of what is on this assortment. And so, Neural Neighbors was our preliminary try and reply this query.
As this mission went on, we began working up in opposition to limitations and asking larger questions. For instance, as an alternative of simply wanting on the photos, what would it not be like to have a look at your complete assortment ? With the intention to reply this query, we wanted a extra performant rendering layer.
So we determined to make the most of TensorFlow, which allowed us to extract vector illustration of every picture. We then compressed the dimensionality of these vectors right down to 2D. However for PixPlot, we determined to make use of a special dimensionality discount method referred to as umap. And that introduced us to the primary launch of PixPlot.
The thought right here was to take the entire assortment, shoot it down into 2D, after which allow you to transfer by it and have a look at the photographs within the assortment whereby we count on photos with comparable content material to be positioned shut by each other.
And so it is simply developed from that early genesis and Neural Neighbors by to the place it’s immediately.
What impressed you to launch PixPlot as an open supply mission?
Within the case of PixPlot, I used to be working for Yale College, and we had a aim to make as a lot of our contributions to the software program world as doable open and publicly accessible with none business phrases.
It was an enormous privilege to spend time with the lab and construct software program that others discovered helpful. I’d say much more typically, in my private life, I actually like constructing issues that individuals discover helpful and, when doable, contributing again to the open supply world as a result of, I believe, so many people be taught from open supply.
