Are you a bad decision-maker?

Cassie Kozyrkov, the Head of Decision Intelligence at Google, just published the article with this title. She writes: The objective of this article is to teach you the most fundamental principle in decision analysis: The quality of a decision should be evaluated using only the information available to the decision-maker at the time the decision was madeLink

The Poet of Logic Programming

An interview with Prof. Robert Kowalski, the co-creator of the field of logic programming and of the language Prolog. The conversation ranges over the history of Prolog, the ill-famed Fifth Generation Computer Systems project, the relation between symbolic AI and connectionist AI including deep learning, why rule engines fail at logic, and the future of logic programming. Prof. Bob  Kowalski was our presenter at RuleML+RR+DecisionCAMP in 2017 in London. Link

Pre-DecisionCAMP Sessions on Zoom/Slack

DecisionCAMP LIVE will start on June 29 – see the Program. We decided to run several online Zoom/Slack sessions before the Camp to give our presenters and attendees an opportunity to get used to the online format. It is also a good opportunity for BR&DM practitioners worldwide to share their latest achievements and real-life challenges.

Our first pre-conference session will be held on Friday May 22 at 12:00 PM EST. Baljeet Singh from Rulematix will present “Excel based Decision Services Testing Framework”. We will send Zoom invites to everybody who registered on Slack. Anyone can use this link to join DecisionCAMP on Slack: Join

Why intelligences fail?

Alain Chabrier, from IBM Decision Optimization Team: “These days, everyone has become an expert. Everyone knows about Covid-19, everyone has an opinion on what should have been done before, what should be done now, and what should be done later. I am not an virus expert, but I know a bit about Artificial Intelligence, so while I was a few days off, I had time to think about how (all) intelligence(s) fail.Link

Thoughts on Amazon Fraud Detector

Kenny Shi, a fraud prevention professional,  shares his thoughts on AWS’s offering of  Amazon Fraud Detector. Besides many interesting capabilities, it includes a simplified Fraud Detector’s expression language: “When writing decision rules, the available variables include those supplied in the training data set (email, time, IP), plus the model score. What would be exciting is to offer the augmented and transformed variables, which AWS has added insight to, to rule writing as well.”  Link

SaaS is taking over the cloud computing market

SaaS (Software as a Service) is taking over the cloud computing market. According to Gartner, SaaS growth is averaging $200 billion in year. Customers like SaaS as they only need to pay for what they actually use without owning the underlying infrastructure. Cloud vendors offer very flexible pay-as-you-go pricing models, however their implementations could be quite tricky. Our May-2020 Challenge offers you to implement a typical example of pay-as-you-go pricing rules. Link

Small is Good

In his article “The End of Agile” Kurt Cagle wrote: “The Agile Manifesto, like most such screeds, started out as a really good idea. The core principle was simple – you didn’t really need large groups of people working on software projects to get them done. If anything, beyond a certain point extra people just added to the communication impedance and slowed a project down.” What did go wrong?  Read here

CMMN Method and Style

Bruce Silver: Case Management Model and Notation (CMMN) is the poor stepchild of process modeling standards.  It was developed a decade ago, around the same time as BPMN 2.0.  In case management, the order of actions typically cannot be precisely defined at design time, and many different things happen concurrently.  The list of available actions changes with the state of the case, and initiation of those actions is typically the result of manual case worker decisionsLink
