Today we’re joined by Rob Walker, vp of decisioning & analytics and gm of one-to-one customer engagement at Pegasystems. Rob, who you might know from his previous appearances on the podcast, joins us to discuss his work on AI and ML in the context of customer engagement and decisioning, the various problems that need to be solved, including solving the “next best” problem. We explore the distinction between the idea of next best action and determining it from a recommender system, how the combination of machine learning and heuristics are currently co-existing in engagements, scaling model evaluation, some of the challenges they’re facing when dealing with problems of responsible AI and how they’re managed. Finally, we spend a few minutes digging into the upcoming PegaWorld conference, and what attendees should anticipate at the event.

TWIML hosts a variety of events throughout the year to educate and inspire our listeners and community members. Take a look at our upcoming events below and click the events link to find out more about past events.

TWIMLcon 2022

TWIMLcon: AI Platforms returns October 4-7, 2022!

The virtual conference will once again bring to light the platforms, tools, technologies, and practices necessary to enable and scale enterprise machine learning and AI.

Check back soon for speaker and session announcements, or visit the TWIMLcon: AI Platforms 2022 event page to register for updates.




Our conversations with hundreds of ML/AI practitioners and teams have demonstrated that effective tools and platforms are the key to delivering ML and AI at scale—allowing teams to innovate more quickly and consistently.

The TWIML Solutions guide helps you identify technologies and solutions that can help your organization deliver models into production more quickly and efficiently.

Latest Research

Long before starting the TWIML podcast, I worked at the intersection of the two technology shifts that ultimately enabled modern artificial intelligence: cloud computing and big data. AWS was the clear leader in cloud even back then, so I jumped at the opportunity to attend the company’s first re:Invent conference way back in 2012.

Pachyderm provides the ability to modularize, orchestrate, and scale the steps of your ML pipeline within a language-agnostic platform — with the added ability to trace the lineage and versioning of both code and data.

A recent tweet from Soft Linden illustrated the importance of strong responsible AI, governance and testing frameworks for organizations deploying public-facing machine learning applications.

Following a search for “had a seizure now what”, the tweet showed that Google’s “featured snippet” highlighted actions that a University of Utah healthcare site explicitly advised readers NOT to take.

We’re proud to announce the new TWIML Solutions Guide, a directory of machine learning tools and platform technologies for data scientists, ML engineers and other AI practitioners and leaders. The Guide aims to help them explore and compare open source and commercial offerings for building, delivering, and improving their ML and AI projects. This post explains why we think the guide is important and highlights some of its key features.

In order to help enterprise machine learning, data science, and AI innovators understand how model-driven enterprises are successfully scaling machine learning, we have conducted numerous interviews on the topic.

In this post, we present three representative ML platforms: Airbnb’s Bighead, Facebook’s FBLearner, and LinkedIn’s Pro-ML. Each of these platforms was developed in response to the unique situation, challenges, and considerations faced by its creator.

Explore Solutions

Pachyderm is an enterprise-grade, open source data science platform that makes explainable, repeatable, and scalable machine learning and artificial intelligence a reality. The Pachyderm platform brings together version control for data with the tools to build scalable end-to-end ML/AI pipelines while empowering users to develop their code in any language, framework, or tool of their choice. Pachyderm has been proven to be the ideal foundation for teams looking to use ML and AI to solve real-world problems in a reliable way.

Dataiku Data Science Studio is the collaborative data science software platform for teams of data scientists, data analysts, and engineers to explore, prototype, build, and deliver their own data products more efficiently.

Cloudera Machine Learning allows users to build, deploy, and scale ML and AI applications through a repeatable industrialized approach and turn data into decisions at any scale, anywhere.

Introducing the first enterprise-ready feature store for machine learning. Built by the creators of Uber Michelangelo, Tecton provides the first enterprise-ready feature store that manages the complete lifecycle of features — from engineering new features to serving them online for real-time predictions.

ClearML is a complete MLOps open-source solution to manage your entire workflow in a unified interface, enabling experiment management through orchestration and DataOps including actual deployment and remote management across teams and departments.

Run:ai Atlas is a compute orchestration platform that speeds up data science initiatives by pooling all available GPU resources and then dynamically allocating resources as you need them. One-click execution of experiments, no code changes required by the user, and most importantly, no more waiting around to access GPUs. Atlas automates provisioning of multiple GPU or fractions of GPU across teams, users, clusters and nodes, and IT gains control and visibility over the full AI infrastructure stack through comprehensive, easy-to-use dashboards.


The TWIML Community is a global network of machine learning, deep learning and AI practitioners and enthusiasts.

We organize ongoing educational programs including study groups for several popular ML/AI courses such as Deep Learning, Machine learning and NLP, Stanford CS224N, and more. We also host several special interest groups focused on topics like Swift for Tensorflow, and competing in Kaggle competitions.
