Ep 6: Extracting Data from Old Documents with Rosa Lin, Founder, Tolstoy
Rosa Lin is the founder of Tolstoy [www.tolstoy.ai], which specializes in extracting data from documents. As I learned, this is a much tougher problem than traditional OCR! It requires a combination of deep learning and classic CV methods. Rosa also talks about her fascinating background as a journalist and her experience going through Y-Combinator.

Ep 4: ROI from ML at "Reasonable Scale" E-Commerce Companies with Ciro Greco
Ciro Greco has built ML systems used at many named-brand retailers. In this episode, he gives us tips on getting value out of ML at “reasonable scale” companies with NLP and information retrieval. The concept of “reasonable scale” was one he returned to, and he clearly has a very nuanced understanding of that segment and how they are different from the hyper scale tech giants. He also brings advanced ideas like embeddings from NLP towards e-commerce personalization.
For more episodes, visit https://yaoshiang.com/podcast.html.
Show Notes:
1:36: Key differences in applying ML at “reasonable scale” companies like major retailers where you can’t just “big-data” your way out of problems, compared to the hyper scale tech giants.
3:22: The basics of personalization: suggestions, search, recommendations, and categories.
4:38: A non-obvious challenge: how to personalize for non-logged-in users without a profile who visit infrequently.
9:00: Different incentives for reasonable scale vs hyper scale companies.
9:44: Getting your data right: data ingestion, data practices, organizing teams around data, transforming data, infrastructure for flexible data access, so that you can make developers productive when you have finite resources.
11:23: Learning from experience that data - replayability and replicitability - is more important than modeling.
12:58: Learnings from experiences at presenting at top tier conferences: so many published papers come from the hyper scale companies.
14:19: Taking session data and catalog data to create a “product to vector” embedding to personalize an experience.
19:20: Requirements on how to sell: the sales people must communicate to the “people who write the check” that data integration is a first class citizen, not a downstream task, to achieve ROI.
21:09: Dynamics of regulatory and privacy issues, and how to tackle them as an organization.
24:10: Ciro talks about his personal journey into ML, starting with a PhD in neuroscience and linguistics.
25:46: Early challenges in applying deep learning to NLP.
26:22: The “a ha” moment that led to Ciro’s first startup delivering search products.
27:55: Changes in the role of a data scientist over the past decade. From the role of PhDs who had to tackle problems with very little tooling, to today where there are so many tools available. And a shift towards understanding products and customers.

Trailer
Welcome to the Building Things with Machine Learning Podcast.
Every episode, I’ll be interviewing someone who building really interesting products using machine learning.
Our focus is really on applications:
Medical diagnostics
Autonomous vehicles & advanced driver assistance systems (ADAS)
Geospatial analytics
Media and Content analysis
Manufacturing
Logistics
And AEC, Architecture / Engineering / Construction
What you won’t get are coding tips or research papers. Although ML developers are definitely part of our audience, so are product managers and marketers and entrepreneurs - anyone who wants to see how machine learning is being used in action.
I wanted to start this podcast because Building things with machine learning is a different discipline than traditional software development.
Some big differences:
A developer has a lot less control than traditional software.
ML is also used to solve many problems in the real world where it must be paired with physical sensors and actuators and robotics.
Finally, ML is never perfect - it’s always a game of probabilities - so this is a new way of thinking about things than the traditional concept of software, where it’s realistic to think about stamping out every single bug and defect. In ML, you have to build applications that you accept will not be 100% accurate.
I hope you get something out of the “Building Things with Machine Learning” podcast!
