関数名、メソッド名、変数名でよく使う英単語のまとめ
プログラミングをしていると関数名、メソッド名、変数名をどうするか悩みます。 ロジックより命名に時間を費やすこともざらにあります。翻訳したり、一般的な命名規則なのかいつも検索して大変です。 よく使うサイトの内容をコピってメモしておく 関数名とメソッド名の違いについて よく使う英単語のまえに、いつもごっちゃにして使っているけど、定義はこんな感じ 「関数」と「メソッド」の違い 似ているところ どちらも何か（引数）を入れると処理をして何か（戻り値）を返してくれます。 違うところ やってること自体は大差ありません。概念としては違います。 メソッドはオブジェクト指向で登場する用語で、オブジェクトの動作を定義したものです。 まずオブジェクトありきなのですね。一方の関数は、オブジェクト云々は関係ありません。 個人的な使い分け Java で登場する関数は「メソッド」です。C 言語で登場する関数は「関数」と呼
January 30, 2023 In this post, we'll implement a GPT from scratch in just 60 lines of numpy. We'll then load the trained GPT-2 model weights released by OpenAI into our implementation and generate some text. Note: This post assumes familiarity with Python, NumPy, and some basic experience with neural networks. This implementation is for educational purposes, so it's missing lots of features/improv
概要 はじめに Qlibの試用 動作条件 使用したrequirements.txt データの取得 予測の実施 出力 図示 ソースコード バックテストでのポートフォリオ分析 リスク分析、分析モデル おわりに 概要 本記事では、Qlibを使用して、機械学習パイプライン環境を構築する第一歩について述べる。 はじめに このブログの趣旨としては、当初は「戦略作成」→「戦略検証」→「戦略稼働」→「成果の評価」→「戦略へフィードバック」といったサイクルを管理できるような自動トレーディングシステムを作ることを考えていた。 最近、すこし株取引から離れていたのだが、最近になってまたやり始めようかなと思い、色々と現在の状況を調べはじめた。 その中で、MicrosoftのリポジトリにQlibというものがあるのを見つけた。これが2020年の8月から作られたもので、現在でもメンテされており、もしかするとこれがやりたい
4 Pandas Anti-Patterns to Avoid and How to Fix Them
pandas is a powerful data analysis library with a rich API that offers multiple ways to perform any given data manipulation task. Some of these approaches are better than others, and pandas users often learn suboptimal coding practices that become their default workflows. This post highlights four common pandas anti-patterns and outlines a complementary set of techniques that you should use instea
Most of my readers are probably familiar with procedural programming, object-oriented programming (OOP), and functional programming (FP). The majority of top programming languages on all of the language popularity charts (like TIOBE) support all three to some extent. Even if a programmer avoided one or more of those three paradigms like the plague, they’re likely at least aware of them and what th
A 100x speedup with unsafe Python
We're going to speed up some numpy code by 100x using "unsafe Python." Which is not quite the same as unsafe Rust, but it's a bit similar, and I'm not sure what else to call it... you'll see. It's not something you'd use in most Python code, but it's handy on occasion, and I think it shows "the nature of Python” from an interesting angle. So let's say you use pygame to write a simple game in Pytho
RAPIDS Forest Inference Library: Prediction at 100 million rows per second
IntroductionRandom forests (RF) and gradient-boosted decision trees (GBDTs) have become workhorse models of applied machine learning. XGBoost and LightGBM, popular packages implementing GBDT models, consistently rank among the most commonly used tools by data scientists on the Kaggle platform. We see similar interest in forest-based models in industry, where they are applied to problems ranging fr
今回は DeepSpeed-Chat による RLHF のご紹介です。正直、データセットや計算資源の都合もあり、とりあえず動かしてみました！的な話にはなりますが、RLHF の効果が実際に確認できるか見てみたいと思います。 1. はじめに 今回は DeepSpeed-Chat1 を使って RLHF を試してみたいと思います。RLHF は Reinforcement Learning from Human Feedback の略で文字通り「人からのフィードバックを用いた強化学習」ということですね。OpenAI が InstructGPT(ChatGPT の元になったモデル)2 で使ったことで注目された手法になります。 LLM がらみで何か記事にしたいと思いつつ、日々新たな LLM が発表されている昨今に、隔月＆内容が実時間から月単位で遅れ気味wの本連載です。 「どうしたもんかな。。。」と悩みに

This article is a translation, the original version is available here. I started using the OCaml language regularly around 2012, and since then, my interest and enthusiasm for this language have only grown. It has become my preferred choice for almost all my personal projects, and it has also influenced my professional choices. Since 2014, I have been actively participating in public conferences d
I did this in 2020 and then again in 2021, but I’m in the mood to look around again. Let’s look through Are We GUI Yet? and see what’s up these days. The task today is to have a text label and an input field that can change the text in the label. In React, for example, this is basically free: const Demo = () => { let [state, setState] = useState("Hello, world!"); return ( <div> <p>{state}</p> <inp
Database Fundamentals
About a year ago, I tried thinking which database I should choose for my next project, and came to the realization that I don't really know the differences of databases enough. I went to different database websites and saw mostly marketing and words I don't understand. This is when I decided to read the excellent books Database Internals by Alex Petrov and Designing Data-Intensive Applications by

In this post, I will explain the details of how RWKV generates text. For a high level overview of what RWKV is and what is so special about it, check out the other post about RWKV. To explain exactly how RWKV works, I think it is easiest to look at a simple implementation of it. The following ~100 line code (based on RWKV in 150 lines) is a minimal implementation of a relatively small (430m parame

Pandas is a very popular tool for data analysis. It comes built-in with many useful features, it's battle tested and widely accepted. However, pandas is not always the best tool for the job. SQL databases have been around since the 1970s. Some of the smartest people in the world worked on making it easy to slice, dice, fetch and manipulate data quickly and efficiently. SQL databases have come such

Reindex, Transform, and Aggregate datasets using pandas Library
Most of the time, the dataset we will get from the business will be dirty and cannot be used straight forward to train machine learning models. Therefore, we must treat the dataset and bring it to the desired form to input it into an algorithm. This tutorial discusses reindexing, transforming, and aggregating datasets in Pandas. What are Reindexing, Transforming, and Aggregating?Reindexing, transf

Physical Like many of you, I've got hardware on my desk that's sending UDP packets, and the time has come to take a closer look at them. Most "low-level" networking tutorials will bottom out somewhere at "use tcpdump to see raw packets".
