Christmas Challenge at Kaggle

“Santa has exciting news! For 100 days before Christmas, he opened up tours to his workshop. Because demand was so strong, and because Santa wanted to make things as fair as possible, he let each of the 5,000 families that will visit the workshop choose a list of dates they’d like to attend the workshop. When all the families have sent Santa their preferences, he’s realized it’s impossible for everyone to get their top picks, so he’s decided to provide extra perks for families that don’t get their preferences. Santa needs the help to optimize which day each family is assigned to attend the workshop in order to minimize any extra expenses that would cut into next years toy budget! Can you help Santa out?” Link

New release of MiniZinc

MiniZinc is a free and open-source constraint modeling language. You can use MiniZinc to model constraint satisfaction and optimization problems in a high-levelsolver-independent way, taking advantage of a large library of pre-defined constraints. Your model is then compiled into FlatZinc, a solver input language that is understood by a wide range of solvers.

DMN 1.3 Approved

The new version 1.3 of the Decision Modeling and Notation (DMN) standard was approved by the OMG AB on Dec. 9, 2019. Apart from numerous corrections and clarifications, it gives us visual grouping, temporal reasoning, and better examples. It should be published in 2-3 months; until then OMG members can see it here.

Explainability and Interpretability

Explainability of decisions produced by machines is one of the hottest topic these days (see XAI). Explainable AI usually makes decisions using a complicated black box model, and uses a second (posthoc) model created to explain what the first model is doing. Interpretable AI concentrates on models that can themselves be directly inspected and interpreted by human experts. The recent paper “Stop explaining  black box machine learning models for high stakes decisions and use interpretable models instead” shows the difference between explainability and interpretability, and states that the former may be problematic.

How can we persuade people to trust an algorithm?

On Dec. 4 Andrew Ng listed several important techniques  that can persuade people to trust an algorithm. “Trust isn’t just about convincing others that our solution works. I use techniques like these because I find it at least as important to convince myself that a solution works, before I ask a customer to rely on it.” Here they are: Continue reading

Dichotomy between Machine Learning and Business Rules

Prof. Hafedh Mili published an article “On the fallacy of the dichotomy between analytics/machine learning, and business rules“. The main points are:

  • We have been there before
  • Business rules rely on analytics
  • If you need to explain your decisions to someone, you need business rules
  • Deep learning cannot compensate for a shallow understanding for your domain
  • Business rules are explainable AI for business.                     Link
