  • Qlibを使った機械学習パイプライン環境の構築 投資の取引戦略最適化と機械学習モデル作成の省力化を目指して - 株のシステムトレードをしよう - 1から始める株自動取引システムの作り方

    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

      • Data Manipulation: Pandas vs Rust

        Introduction Pandas is the main Data analysis package of Python. For many reasons, Native Python has very poor performance on data analysis without vectorizing with NumPy and the likes. And historically, Pandas has been created by Wes McKinney to package those optimisations in a nice API to facilitate data analysis in Python. This, however, is not necessary for Rust. Rust has great data performanc

              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

                  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
