[1907.02260] On Explaining Machine Learning Models by Evolving Crucial and Compact Features
Feature construction can substantially improve the accuracy of Machine Learning (ML) algorithms. Genetic Programming (GP) has been proven to be effective at this task by evolving non-linear combinations of input features. GP additionally has the potential to improve ML explainability since explicit expressions are evolved. Yet, in most GP works the complexity of evolved features is not explicitly bound or minimized though this is arguably key for explainability. In this article, we assess to what extent GP still performs favorably at feature construction when constructing features that are (1) Of small-enough number, to enable visualization of the behavior of the ML model; (2) Of small-enough size, to enable interpretability of the features themselves; (3) Of sufficient informative power, to retain or even improve the performance of the ML algorithm. We consider a simple feature construction scheme using three different GP algorithms, as well as random search, to evolve features for five ML algorithms, including support vector machines and random forest. Our results on 21 datasets pertaining to classification and regression problems show that constructing only two compact features can be sufficient to rival the use of the entire original feature set. We further find that a modern GP algorithm, GP-GOMEA, performs best overall. These results, combined with examples that we provide of readable constructed features and of 2D visualizations of ML behavior, lead us to positively conclude that GP-based feature construction still works well when explicitly searching for compact features, making it extremely helpful to explain ML models.

Stollen Bars
I am bookmarking as they come out of the oven, so what I can say is more nuts, less marzipan, added candied ginger. Made the topping with scant 2 tbs butter.
Stodgy texture, despite being fully baked.

The Crisis has passed and Barry's still alive but his life has been irreparably affected. And after leaving Caitlin and his apartment for a possible last time Barry goes for a run and remembers how his marriage to Iris came to an end and how he ended up living with Caitlin Snow.
ANGST! YES!!! Also, meh, for ship. Barry runs through his timeline; fic told in memory spurts as he's running through time portals.

The Basics - Fallacies of Distributed Systems | Learn Cloud-Native Blog
The CAP theorem, also named Brewer's theorem after computer scientist Eric Brewer, states that it is impossible for a distributed system to simultaneously provide more than two out of the following three guarantees - consistency, high availability, and partition tolerance.

A sleepy confession
When Barry take Caitlin with him to tackle a fire, Caitlin get's a little overwhelmed and it's up to Barry to take care of her for a change. But when a certain doctor is extremely tired, she tends to just blurt things out that aren't meant to be blurted out.
Meh, for ship

West Family Dinner
Barry Allen is nervous to attend the first West family dinner since he and Iris got divorced, and he's also nervous to hide his secret from the mind-reader Cecile.

Nora's Betrayal and Barry's Realisation
Barry and Iris argue over sending Nora back. What would happen if Barry had confided in a certain ice queen afterwards?
Slightly OOC. Disagree with Iris bashing/angry Barry/two-day new relationship, but Snowbarry. For ship.

The war has dragged on into a stale détente until Draco Malfoy Snatches Hermione Granger from a Muggle park. His plans could upset the balance of the war, tipping things toward the light. What Hermione doesn't expect is that he'll upset her treacherous heart as well.
Draco needs to get out and enlists Hermione for help. Not one of my Colunbrina faves, but she wrote it, so ;p

[1902.11214] A Multilayer Structure Facilitates the Production of Antifragile Systems in Boolean Network Models
Antifragility is a property to not only resist stress and but also to benefit from it. Even though antifragile dynamics are found in various real-world complex systems where multiple subsystems interact with each other, the attribute has not been quantitatively explored yet in those complex systems which can be regarded as multilayer networks. Here we study how the multilayer structure affects the antifragility of the whole system. By comparing single-layer and multilayer Boolean networks based on our recently proposed antifragility measure, we found that the multilayer structure facilitated the production of antifragile systems. Our measure and findings can be utilized for many applications from understanding properties of biological systems with multilayer structures to designing more antifragile engineered systems.
