For a full day on December 14, 2020, LinkedIn sponsored a virtual workshop called Metadata Day, followed by a public online meetup called Metaspeak. View videos of the event on their website including a set of lightning talks provided by several of the speakers.

The gist is that circa 2018, the pending regulatory compliance for GDPR, CCPA, etc., drove urgency in enterprise organizations to have a better understanding and accountability about datasets and their use cases. Several firms, about a dozen, responded in strikingly similar ways — which signals that a kind of “design pattern” is emerging for how to…

Registration is open for the Metaspeak Meetup (a free online event) on December 14, 2020, hosted by LinkedIn https://metadataday2020.splashthat.com/

This is the public portion of the Metadata Day 2020 workshop, which convenes leaders from several open source projects for graph-based dataset metadata management, along with thought leaders in metadata management and dataset governance from Google, IBM, UC Berkeley, etc.

Igor Perisic, CDO @ LinkedIn, will present our welcome address, followed by two panels of expert practitioners who will summarize outcomes from our workshop earlier in the day — (1) focus on use cases, and (2) focus on production at scale…

RLlib is an open-source library in Python, based on Ray, which is used for reinforcement learning (RL). This article presents a brief tutorial about how to build custom Gym environments to use with RLlib. You can use this as a starting point for representing your own use cases to solve with reinforcement learning (RL).

Note that this article is a follow-up to:

RLlib is an open-source library in Python, based on Ray, which is used for reinforcement learning (RL). This article provides a hands-on introduction to RLlib and reinforcement learning by working step-by-step through sample code. The material in this article, which comes from Anyscale Academy, provides a complement to the RLlib documentation and is especially intended for those who have:

• some Python programming experience
• some familiarity with machine learning
• no previous work in reinforcement learning
• no previous hands-on experience with RLlib

Key takeaways: we will compare and contrast well-known RL examples running in RLlib to explore the essential concepts and terminology…

Their community was still reeling from an incident where local police had murdered an unarmed black man. Protests grew as the public was outraged in the wake of a court decision to acquit the murderers. Then a crowd gathered in a major city as a local protest leader made a public reading of a controversial document. Afterward, protesters marched to a nearby park and pulled down the statue of a corrupt government leader portrayed as a Roman emperor.

The date was July 9, 1776. The city was NYC. The man whose death had catalyzed protests was Crispus Attucks. He’d been…

Derwen, Inc., announces a new AI service for a novel form of risk analysis, addressing business needs during a time of heightened uncertainty to augment due diligence practices, while emphasizing resilience and ethical practices.

First and foremost, our hearts go out to those who have been victims of illegal and unjust police aggressions, to their family, friends, and neighbors. And also to those who have lost loved ones during the pandemic. We support those who are actively protesting, calling out the systematic racial violence which is so deeply ingrained in the US.

Response to Urgent Business Needs

In response to urgent business needs brought on…

Throughout the global pandemic, many people have spent lots of time viewing maps that visualize data. Important data. People who work in data science are probably seeing increased needs to work with geospatial data, especially for visualizations. There are increased needs to understand metrics about geographic regions, to analyze supply chain, make plans that take into account local conditions and rules, etc.

This article shows how to use two popular geospatial libraries in Python:

• geopandas: extends Pandas to allow spatial operations on geometric types
• geoplot: a high-level geospatial plotting library

The second library is especially helpful since it builds on…

Strategy notes for technology ventures during a “pseudo-jackpot” period subsequent to the COVID-19 pandemic and its economic fallout.

The following is a collection of personal notes. Most of these points compare personal reflections from previous economic crises w.r.t. the current pandemic. This is especially targeted at questions about leading an early stage technology venture.

Our world has changed. On the other side of a global crisis, where do we land? As an enormous range of possible risks and opportunities open up, which strategies are indicated? How do we prepare for a so-called “new normal” and its emerging business environments?

The…
