Challenge June-2021 “Where is gold?”


This month we asked our readers to use their favorite BR/DM tools or just common sense to solve a simple puzzle “Which box contains the gold?” The very first quick solution by Jan Vanthienen uses decision tables to classify different possibilities. It’s interesting that these decision tables don’t need to be executable as their design already resolves the problem. Of course, as Jan wrote, “a general formulation of the problem will be better” and probably a larger problem with more objects and known relationships between them (e.g. notorious Zebra Puzzle) would be more difficult to solve without a tool. Let’s wait for more solutions. Link

“You’re crazy if you don’t start in the cloud; you’re crazy if you stay on it”

This A16Z article argues that SaaS companies should move back from the cloud to their own data centres once they scale. “Cloud is cheaper and better early on and more costly later in a company’s evolution… Make sure your system architects are aware of the potential for repatriation early on, because by the time cloud costs start to catch up to or even outpace revenue growth, it’s too late. Even modest or more modular architectural investment early on — including architecting to be able to move workloads to the optimal location and not get locked in — reduces the work needed to repatriate workloads in the future. The popularity of Kubernetes and the containerization of software, which makes workloads more portable, was in part a reaction to companies not wanting to be locked into a specific cloud.Link

DecisionCAMP June-9 Session

Date: Wed June 9, 2021 at 12:00 PM EST (New York Time)
Title: “Performance of a Large Decision Table Deployed as a Microservice
Presenter: Dr. Bob Moore, JETset Business Consulting.

: There have been a number of solutions submitted to February’s decision modelling challenge. This talk inspired by the solutions to the challenge, looks at some aspects of managing large decision tables, considering the comparative performance of various solutions and suggesting things one should consider when trying to come up with an optimal approach when dealing with large decision tables.

Data-centric AI development

Andrew Ng writes that ML research mainly concentrates on algorithms while the real-world applications deal more with data quality. “Benchmarks and competitions in which teams are asked to improve the data rather than the code would better reflect the workloads of many practical applications. I hope that such benchmarks also will spur research and help engineers gain experience working on data.”  Link

ML has a proof-of-concept-to-production gap

Andrew Ng: “All of AI, not just healthcare, has a proof-of-concept-to-production gap. The full cycle of a machine learning project is not just modeling. It is finding the right data, deploying it, monitoring it, feeding data back [into the model], showing safety—doing all the things that need to be done [for a model] to be deployed. [That goes] beyond doing well on the test set, which fortunately or unfortunately is what we in machine learning are great at.” Link

In memory of Dr. Harold Boley

Dr. Harold Boley passed away in December 2020. Being a well-known scientist in the semantic web movement and the Chair of RuleML from 2001 to 2020, Harold devoted a lot of efforts to integrate the academic research in the area of rules-based knowledge representation with the commonly used rule engines. In particular, he initiated and actively pushed the integration of RuleML and DecisionCAMP and coined the name “Declarative AI” for a summit that annually brings together researchers and practitioners. This year the Declarative AI will be held in September for the first time without Harold but the Rule Challenge will carry his name. Link

Challenge May-2021 “COVID Testing”


Our May-2021 Challenge asks you to implement a decision model that determines who should undergo subsequent COVID-19 testing based on a number of symptoms for COVID-19 were identified, such as coughing, sneezing, or fever. Depending on the number of symptoms a patient presented, subsequent PCR testing was conducted. Link
