The document summarizes key highlights from the 2022 Statistical Review of World Energy. It notes that primary energy use increased 1% in 2022 to reach 2.8% above 2019 levels, driven mostly by non-OECD countries. Carbon emissions reached a new record high in 2022 of 39.3 billion tonnes, with energy-related emissions increasing 0.9%. Global prices of oil, natural gas, coal, and key minerals like lithium and cobalt increased sharply in 2022.
Ce premier cours introduit la notion de système embarqué en commençant par en donner une définition. Il les caractérise ensuite sur base de plusieurs critères : type d'application, de fonction visé, taille, fiabilité, efficacité. Il présente ensuite plusieurs aspects hardware (unité de calcul, architecture matérielle, composants clés) et software (niveau de programmation, processus de développement). Enfin, il conclut en discutant sur ce qu'est un ingénieur en systèmes embarqués.

The document proposes a decentralized crowdfunding platform leveraging blockchain technology and smart contracts. The platform aims to provide a secure, transparent and trustworthy ecosystem for crowdfunding projects with a positive social impact. It seeks to enable decentralized crowdfunding, utilize blockchain for security and transparency, and implement smart contracts to automate the distribution of funds. This is aimed to revolutionize crowdfunding by embracing the efficiency, transparency and trust offered by blockchain.
A review of one of the most popular methods of clustering, a part of what is know as unsupervised learning, K-Means. Here, we go from the basic heuristic used to solve the NP-Hard problem to an approximation algorithm K-Centers. Additionally, we look at variations coming from the Fuzzy Set ideas. In the future, we will add more about On-Line algorithms in the line of Stochastic Gradient Ideas...
Viterbi decoding algorithm is a complete decoding algorithm with zero probability of decoding failure, but larger probability of decoding error than an incomplete decoder. It is practical for binary codes of small constraint length. Stack algorithm reduces computational work by keeping track of paths it has already traversed...

These are the slide deck in french of a 40 minute lecture given at College de France on 23 February 2022 in the curriculum "Information and Complexity" of Prof. Stephane Mallat. https://www.college-de-france.fr/site/stephane-mallat/seminar-2022-02-23-11h15.htm
The document describes the Grasshopper Optimization Algorithm (GOA), a recent swarm intelligence algorithm. GOA mimics the behavior of grasshopper swarms and their social interactions. Each grasshopper in the algorithm represents a potential solution. The position of each grasshopper is determined by three forces: social interaction between grasshoppers, gravity, and wind. GOA balances exploration and exploitation to optimize problems and prevent premature convergence.

In this talk, Dmitry shares his approach to feature engineering which he used successfully in various Kaggle competitions. He covers common techniques used to convert your features into numeric representation used by ML algorithms.
This document provides an overview of the Artificial Bee Colony (ABC) algorithm. It describes how ABC was inspired by the foraging behavior of honey bees. The core components of the ABC algorithm are introduced, including the initialization phase, employed bee phase, onlooker bee phase, and scout bee phase. Pseudocode and a flowchart depicting the steps of the ABC algorithm are presented. Applications of ABC in areas such as optimization, bioinformatics, scheduling, clustering, and engineering are discussed. Finally, the advantages of ABC like simplicity and flexibility are contrasted with limitations such as high computational cost.

WikiWikiWeb (Wiki) is an information sharing system on the Web developed by Ward Cunningham in 1995. Wiki is created as a system for collaboration over the Internet, Wiki came to be used for large-scale Web site, or information sharing for groups, enterprises and individuals. According to the changes of the use cases, various Wiki engines are developed. After almost ten years past, various roles of Wiki are appeared. In this paper, we describe the characteristic of Wiki from the first Wiki site, the changes of the use cases, the development of various Wiki engine, and the general view of present Wiki situation.
Introduction for Wiki engine exposition held in 2005. It introduced WikiBase that was the first Wiki and YukiWiki YukiWiki that was able to be called WikiBase for Japanese.
