この記事は Kaggle Advent Calendar 2020 の16日目の記事です。去年ネタ記事*1を書いたので今年は真面目なやつにしました。 はじめに Kaggler はコンペにおいてあらゆる手段を用いて評価指標の改善を目指します。特徴量エンジニアリング、モデルや学習手法の試行錯誤、特殊な前処理・後処理の考案、はたまた Leakage の利用に至るまで、ルールを破らない範囲であれば何でもする*2のが Kaggler です。今挙げた例はそのコンペ固有の性質(データの生成過程・分布、評価指標、... etc.)に着目することで大きな効果をもたらす場合が多いのですが、一方でいずれのコンペにおいても一定の効果が得られる手法があります。それは複数のモデルの予測結果を統合して予測を行う Ensemble です。Ensemble は統合するモデルに多様性があるほど性能が向上すると一般に知られてお
How Netflix Scales its API with GraphQL Federation (Part 2)
In our previous post and QConPlus talk, we discussed GraphQL Federation as a solution for distributing our GraphQL schema and implementation. In this post, we shift our attention to what is needed to run a federated GraphQL platform successfully — from our journey implementing it to lessons learned. Our Journey so FarOver the past year, we’ve implemented the core infrastructure pieces necessary fo

Sorting colors in JavaScript
Sorting colors in JavaScriptJune 22, 2021How to sort colors in JavaScript? Let me tell you a story first. In the project I'm working on right now we used to have 134 colors in use! WTF?! you say. Once I discovered that I thought I'm going to show that to my colleagues, and we will address the problem. Unfortunately, I'm a very visual person (so to say) and I couldn't stand the very random order of

Why I left Rust
There's a lot of speculation about why I left Rust yesterday, so I want to set the record straight in this post. What happened A short timeline of what happened from my perspective, as this is relevant for later: A request went out to the interim leadership group for potential keynote speakers for RustConf. JeanHeyd Meneide was proposed by myself and Manish as a keynote. JeanHeyd is one of the two

SRE for single-tiered software applications | Google Cloud Blog
In cloud operations, we often hear about the benefits of microservices over monolithic architecture. Indeed, microservices help manage hardware being abstracted away and push developers towards resilient, distributed designs. However, many enterprises still have monolithic architectures which they need to maintain. For this post, we’ll use Wikipedia’s definition of a monolith: “A single-tiered sof

I’ve struggled to find references to this online, but heard the name used multiple times this year when describing the approach outlined here.

The general idea of an “Islands” architecture is deceptively simple: render HTML pages on the server, an
