実務において回帰分析を行うに当たっての注意点を改めて挙げてみる - 渋谷駅前で働くデータサイエンティストのブログ
先日のことですが、以下のニュースが統計的学習モデル界隈で話題になっていました。 肝心の箇所が会員限定コンテンツなので簡潔にまとめると、従来モデルよりも説明変数に入れる海域の数を増やした上で、Lasso（L1正則化）回帰で多重共線性を抑えつつ汎化性能を高めるというアプローチを取った、というお話です*1。これは回帰分析という基本に立ち返った、昨今の「猫も杓子も生成AI」という流れからは一線を画した試みで、いかにも玄人好みという感があるなと僕も感じた次第です。 一方で、僕が身を置く広告・マーケティング業界でもMMM (Media/Marketing Mix Models)を初めとして様々なタイプの回帰分析が広く行われていますが、個人的に見聞する範囲では冗談でなく本当にピンキリで、中には「そんなデタラメな回帰分析で本当に役員会の意思決定に使っているんですか？？？」みたいなケースも珍しくありません。
CSSのclass名やJavaScriptの関数名を付けるときに悩んだり、ネタ切れになったことはありませんか？ BEM, OOCSS, SMACSSで命名する場合はそれを使用すればよいのですが、特定のテーマ別にグループ化された単語のリストが必要になるときもあります。そんなときに役立つ単語リストをまとめたClassnamesを紹介します。 Classnames Classnamesは、CSSのclass名やJavaScriptの関数名を付けるときに便利な単語をリスト化したものです。MITライセンスで、商用プロジェクトでも無料で利用できます。
Goにおけるタスクランナーの歴史 npmならnpm run、denoならdeno taskなど言語ツールにタスクランナー機能が付属していることがありますが、Goではそのような機能は提供されていません。 そこでGoのプロジェクトではMakefileがタスクランナーとして用いられることがしばしばありますが、独自の文法、.PHONYを大量に書く必要がある、Makefile警察が飛んでくる、などの問題があります。 Makefile警察「ぐぬぬぬ…」 #taskfile - Qiita タスクランナーとしてMakefileを使うことから脱却すべく、巷ではYAMLベースの「Task」やGoベースの「Mage」が用いられている印象です。 どちらも多少試したことはありますが、主に以下の点が気になりました。 Taskfile.ymlやmagefile.goといったツール独自のファイルを置く必要がある これは
はじめに こんにちは、ken です。お仕事では Go をよく書きます。 最近、Go の公式パッケージであるgolang.org/x/toolsを眺めていたら、なにやら有用そうなパッケージを見つけたので今回はそれについて書こうと思います。 それはegというリファクタリングツールです。 eg とは eg は、例ベースで Go コードをリファクタリングするためのツールです。このツールを使用することで、特定のコードパターンを別のコードに置き換えることができ、効率的にリファクタリングが行えます。 先ほど貼った公式ドキュメントに詳しい説明があるかと思いきや The eg command performs example-based refactoring. For documentation, run the command, or see Help in golang.org/x/tools/ref
On the origins of DS_store
arno.org If you are a Mac user, or if you have transferred files from Mac to Windows, you’re probably familiar with .DS_Store files. But where does this name come from? Back in 1999 I was the technical lead for the Mac OS X Finder at Apple. At that time the Finder code base was some 8 years old and had reached the end of its useful life. Making any changes to it require huge engineering effort, an

こんにちはChoimirai Companyのサンミンです。 0 はじめにDifyがLangChainと決別し、独自の「Model Runtime」を採用したのが2024年の1月。 LangFlowやFlowiseなど複合AIシステムではLangChainに依存した設計が多い。DifyもLangChainベースの設計だったけど今年の1月に独自の「Model Runtime」を発表👏↓。当時は難しい判断だったと思う。が、変化のスピードとDifyが描いてる世界観を考えると正解だった。Difyを勧めるもう一つの理由、です。 https://t.co/AybwXRXkJ9 pic.twitter.com/n7d9aae76N — sangmin.eth | Dify Ambassador (@gijigae) April 24, 2024 LangChainの導入を慎重に考えるべきだとする声は

SummaryMost visual programming environments fail to get any usage. Why? They try to replace code syntax and business logic but developers never try to visualize that. Instead, developers visualize state transitions, memory layouts, or network requests. In my opinion, those working on visual programming would be more likely to succeed if they started with aspects of software that developers already
Introduction At the time of writing, HTTP/3 is supported by 30.4% of the top 10 million websites. This market penetration is astounding, but it seems like all of this progress has been possible almost exclusively by work on browsers, load balancers and CDN providers. What about the backend? How’s HTTP/3 doing there? The answer, sadly, is not as incredible. Because of this, I have been very interes

Last time, we saw how deleting stuff from a test case can be an easy and fun route to the root cause of a bug. It’s less easy and less fun when the test cases get big. The inner loop of test-case reduction can get old quickly: delete stuff, run the special command, check the output to decide whether to backtrack or proceed. It’s rote, mechanical, and annoyingly error prone. Let’s make the computer

What the New York Times Missed: 71 More of the Best Books of the 21st Century
Susanna Clarke, Jonathan Strange & Mr. Norrell (2004) I should not have been surprised that the NYT list skewed heavily away from genre fiction—but missing Susanna Clarke’s world-changing doorstopper of a debut is a particular head-scratcher. On paper, the book still seems daunting in an almost comical way: a Regency-era epic (with footnotes and extensive digressions on philosophy, magic, politics

SPACEでの指標選びは網羅性ではなく関連性と一貫性を持たせて絞り込むことが大切である、さらに…… - mtx2s’s blog
SPACEフレームワークを活用するなら、選択する指標に関連性と一貫性を持たせて絞り込むことが大切です。思いつくかぎりの指標をただやみくもに集めて網羅性を高めても、そこから得られる情報はほとんどないでしょう。 これが、ニコール・フォースグレンらによる論文 "The SPACE of Developer Productivity: There's more to it than you think." を読んだ時に私が感じたことです。 queue.acm.org 本稿は、上述論文に基づいてSPACEフレームワークを解説するとともに、その活用方法についても考察しています。 特に、5つのディメンションについては、論文から読み取りづらい点をフォローするようにしました。ここが理解できないと、フレームワークの魅力がなくなってしまいます。実際、開発チームのマネージャーらやメンバーらと話していると、SPAC

PySkyWiFi: completely free, unbelievably stupid wi-fi on long-haul flights | Robert Heaton
The plane reached 10,000ft. I took out my laptop, planning to peruse the internet and maybe do a little work if I got really desperate. I connected to the in-flight wi-fi and opened my browser. The network login page demanded credit card details. I fumbled for my card, which I eventually discovered had hidden itself inside my passport. As I searched I noticed that the login page was encouraging me
Scientists had speculated that "lunar pits" like this could be cave entrances - now they have proof Scientists have for the first time discovered a cave on the Moon.

Python is a wonderful programming language. I’ve used it to build webapps, deep learning models, games, and do numerical computation.

Where Should Visual Programming Go? There’s a wonderful article by Sebastian Bensusan: “We need visual programming. No, not like that.” (the dot is part of the title ¯\_(ツ)_/¯).

Why? They try to rep

Marketing Mix Modeling has been promoted as the one method to shed light on the effect of marketing. Not quite coincidentally, this is mainly supported by people that have a self-serving interest to advocate MMM. Opposing standpoints are few and far between. In this post, I
