Build Composable And Reusable Feature Engineering Pipelines with Feature-Engine - Episode 338

October 31, 2021 Tobias Macey Comments Off on Build Composable And Reusable Feature Engineering Pipelines with Feature-Engine - Episode 338

Every machine learning model has to start with feature engineering. This is the process of combining input variables into a more meaningful signal for the problem that you are trying to solve. Many times this process can lead to duplicating code from previous projects, or introducing technical debt in the form of poorly maintained feature pipelines. In order to make the practice more manageable Soledad Galli created the feature-engine library. In this episode she explains how it has helped her and others build reusable transformations that can be applied...

Speed Up Your Python Data Applications By Parallelizing Them With Bodo - Episode 337

October 25, 2021 Tobias Macey Comments Off on Speed Up Your Python Data Applications By Parallelizing Them With Bodo - Episode 337

The speed of Python is a subject of constant debate, but there is no denying that for compute heavy work it is not the optimal tool. Rather than rewriting your data oriented applications, or having to rearchitect them, the team at Bodo wrote a compiler that will do the optimization for you. In this episode Ehsan Totoni explains how they are able to translate pure Python into massively parallel processes that are optimized for high performance compute systems.

Doing Dask Powered Data Science In The Saturn Cloud - Episode 331

September 10, 2021 Tobias Macey Comments Off on Doing Dask Powered Data Science In The Saturn Cloud - Episode 331

A perennial problem of doing data science is that it works great on your laptop, until it doesn't. Another problem is being able to recreate your environment to collaborate on a problem with colleagues. Saturn Cloud aims to help with both of those problems by providing an easy to use platform for creating reproducible environments that you can use to build data science workflows and scale them easily with a managed Dask service. In this episode Julia Signall, head of open source at Saturn Cloud, explains how she is...

Monitor The Health Of Your Machine Learning Products In Production With Evidently - Episode 330

September 3, 2021 Tobias Macey Comments Off on Monitor The Health Of Your Machine Learning Products In Production With Evidently - Episode 330

You've got a machine learning model trained and running in production, but that's only half of the battle. Are you certain that it is still serving the predictions that you tested? Are the inputs within the range of tolerance that you designed? Monitoring machine learning products is an essential step of the story so that you know when it needs to be retrained against new data, or parameters need to be adjusted. In this episode Emeli Dral shares the work that she and her team at Evidently are doing...

Making Automated Machine Learning More Accessible With EvalML - Episode 329

August 25, 2021 Tobias Macey Comments Off on Making Automated Machine Learning More Accessible With EvalML - Episode 329

Building a machine learning model is a process that requires a lot of iteration and trial and error. For certain classes of problem a large portion of the searching and tuning can be automated. This allows data scientists to focus their time on more complex or valuable projects, as well as opening the door for non-specialists to experiment with machine learning. Frustrated with some of the awkward or difficult to use tools for AutoML, Angela Lin and Jeremy Shih helped to create the EvalML framework. In this episode they...
