Ricardo Manhães Savii: Trying to turn Machine Learning into value

If we can't turn machine learning into value, what good are we? Ricardo Manhães Savii wrote a piece in Medium where he tackles how to technically and visually define the steps to deliver an Intelligent System with the same level of best practice maturity that software development has today. He combines and synthesizes the ideas of some of the best known thinkers in the space to build a thorough architecture of machine learning best practices. You won't want to miss this post and wrap your head around these diagrams!

RappiBank: How to build an efficient machine learning project workflow

Continuing the theme of ML workflow Complexity, Daniel Baena wrote a great overview and tutorial piece outlining the challenges that his team at RappiBank encountered and found ways to solve with DVC including:

  • confusing experiment files with different names
  • disjointed messaging about training and models and dataset changes
  • holding in your head or own notes progress that is not visible to the rest of the team
  • heavy run and re-run times without a modularized system

Daniel shows how all of these things can be solved using DVC.🏆

DAGsHub: Production Oriented Work

Next up, Nir Barazida from DAGsHub created a video on Production-oriented work using a monorepo strategy and focusing on moving from research to production-ready code using Git and DVC. If you are a data scientist trying to wrap your head around going from your notebook to production, this may help!

ML Data Versioning with DVC: How to Manage Machine Learning Data

Piotr Storożenko of Appsilon wrote a great tutorial taking into account the many challenges data scientists and ML engineers encounter in their data versioning efforts and how DVC solves them. Do these scenarios from his article look familiar?

Was it in model_3final.pth or model_last.pth that I used a bigger lerning rate?

When did I start using data preprocessing, during model_2a.pth or model_2aa.pth

Is model_7.pth trained on the new dataset or on the old one?`

Oh, gosh, which set of parameters and data have I used to train model_2.pth? It was pretty good in the end…”

Learning Opportunities

Raviraja Ganta's 10-week course on Basic MLOps

Twitter and LinkedIn were a blaze in the last month when Raviraja Ganta announced his 10-Week Course on MLOps basics. This course is chock full of resoures and practical tutorials to build your MLOps platform and knowledge. Week 3 of the course is about DVC and its ability to solve your versioning and reproducibility challenges. Be sure to check out the course repo as well!

MLOps Community is hosting him to speak about his course on October 20th. Sign up to attend here!

Josh Willis video on COVID simulations with DVC

This week, this Tweet comment led me to this work by Josh Wills. Josh was tapped by DJ Patil to participate in some COVID simulation research early on in the pandemic in which he used DVC. In his presentation about the project, he tells of the tools he used and challenges of the use case. Nice DVC shout out at 19:56! Ah, the fruits of a Twitter 🐇🕳!

September Office Hours Video: Transfer Learning with Milecia McGregor

If you missed last month's Office Hours Meetup, you can now catch the video! Milecia's presentation was based on her blog post on the same topic: Using Experiments for Transfer Learning. If you're curious about transfer learning in general, AlexNet and SqueezeNet in particular, or using DVC experiments and checkpoints to track all that you do, this video's for you!

Quoc-Tien Au: Continuously Learning on the Job as a Data Scientist

This Towards Data Science article by Quoc-Tien Au entitled "The What, Where, and How about continuously learning on the job as a data scientist," speaks to some higher points on the need to have a mindset for continuous learning in the Data Science field. It's packed with great thought processes and resources on what to learn, where to learn, and how to keep learning while still getting your work done. Who stuggles with this? 😅

DVC News

Amsterdam Off-site

Most of our team members from Europe got together in Amsterdam recently for a couple days of brainstorming and team bonding. They went on a Treasure Hunt, ate Ramen (a favorite among our team) and had great discussions on how to make our tools and our team even better! Pictured below from front of the room left, going clockwise (to the back of the room and back up) are David Ortega, Helio Machado, David de la Iglesia Castro, Laurens Duijvesteijn, Ruslan Kupriev (hidden), Dmitry Petrov, Jelle Bouwman, Batuhan Taskaya,Svetlana Sachkovskaya, and Paweł Redzyński.

Be sure to check out this section next month as our Americas team members will meet in San Francisco!
