Solution : Find a cost function $J(\theta)$ of parameter $(\theta_0,\theta_1)$ with $\theta$ that minimise $J$ $$ J(\theta_0,\theta_1) = \dfrac{1}{2m} \sum_{i=1}^m (h_\theta(x^{(i)})-y^{(i)})^2 $$ where $m$ the number of training sets https://cbyad.github.io/posts/fp_ts_1_post/ Tue, 09 Jun 2020 00:00:00 +0000 https://cbyad.github.io/posts/fp_ts_1_post/ This article targets anyone unfamiliar with functional programming (FP) but want to learn about it from scratch. Starting FP with dedicated languages like Haskell, OCaml, Erlang or Scala can take a lot of time for a beginner. FP treats many concepts and it’s impossible to cover them all in a single blog post. But with the basics and some concepts we can considerably improve our code (elegance, conciseness, safety, robustness, maintainability and more). https://cbyad.github.io/posts/dart_monad_post/ Thu, 11 Jul 2019 00:00:00 +0000 https://cbyad.github.io/posts/dart_monad_post/ I will introduce with simple words what monad is? and how can we use it through my library either_option in flutter project? It targets mainly readers who are unfamiliar with this concept, or who want to see how we can do it in an imperative object oriented language. We will focus on two monads: Either and Option … [Read more] https://cbyad.github.io/projects/eo/ Mon, 01 Jul 2019 00:00:00 +0000 https://cbyad.github.io/projects/eo/ [See project] About A small typed and safe library for error handling with functionnal programming concept in Dart and utter project (MIT licence). either_option is a simple library typed for easy and safe error handling with functional programming style in Dart. It aims to allow flutter/dart developpers to use the 2 most popular patterns and abstractions : Either and Option, mainly used in FP language like Scala, Haskell, OCaml,… Installation Package link on pub either_option In your pubspec. https://cbyad.github.io/projects/tckt/ Sat, 01 Sep 2018 00:00:00 +0000 https://cbyad.github.io/projects/tckt/ Real-time event ticketing mobile App with mobile payment service (private project) Stack Backend : TypeScript, Node.js, Koa, RabbitMQ, PostgreSQL, Redis, Chai/mocha, Socket.io, Docker IOS/Android App : Flutter, rxDart, SQLite, Firebase https://cbyad.github.io/projects/tas/ Tue, 01 May 2018 00:00:00 +0000 https://cbyad.github.io/projects/tas/ Static Analyser by abstract interpretation in OCaml for a C-like language… [See project] https://cbyad.github.io/about/ Mon, 01 Jan 0001 00:00:00 +0000 https://cbyad.github.io/about/ I’m Yannick-Alain Couassi-Blé (cbyad), software engineer with 3 years of professional experience. I graduated in 2018 with a Master degree in computer science from UPMC - Université Pierre & Marie Curie (now Sorbonne Université). I’m passionate about theoretical things in CS (Programming Language Theory, Algorithms Design, Machine Learning, Functional Prog,…) as well as their application. [Hardworker - Open mind - Entrepreneur] I like to learn new techs, concepts and share my knowledges by reading/writing blog post, attempt conferences, contribute and promote open source project…
