Today I sit down with Eugene Weinstein, a speech recognition researcher and Engineering Director at Google where he leads an organization that productionizes speech recognition technology across various Google products.
We discuss the evolution of speech recognition, the impact of Transformers, and the challenges of deploying models in production. This episode is packed with insight.
A few things I learned from Eugene:
* Build the model factory. Be able to pre-process your data, tune a model, and evaluate the model for accuracy and load testing as automated as possible.
* Good data is key, but it's hard to get. Eugene shared how even Google struggles with data quality issues and ways to think about handling them.
* How the Transformer architecture changed everything. Eugene breaks down why it was so impactful.
* Scaling AI is an art. The trade-offs between speed and accuracy are constant battles and often need a bit of experience to get it right.
* The benefits of cross-functional collaboration between engineers, researchers, and domain experts. Especially with finding data quality issues.
My favorite quote:
"If adding more data hurts your model performance, it's a red flag. But how do you catch it? There's no substitute for actually looking at your data."
