Instalasi Pytorch di Windows

Prosedur instalasi Pytorch di Windows:

  • Kunjungi situs Pytorch, klik di “Get Started”, atau langsung ke “https://pytorch.org/get-started/locally/
  • Pilih setting yang diinginkan. Misal pada kasus saya: PyTorch versi Stable 1.9.0, OS: Windows, Package:Conda, Language: Python, Compute Platform:CUDA 11.1
  • Perintah untuk instalasi akan diberikan di bagian bawah

Saya menggunakan conda, untuk itu di Windows mesti melakukan dulu instalasi Anaconda Individual Edition atau Miniconda

Global Wheat Head Dataset 2021 Released

I believe that the entire dataset (including bounding box for test images) is released here: https://zenodo.org/record/5092309 1

This dataset is mentioned in the new paper “Global Wheat Head Dataset 2021 1” , in the “Code & Data Section”

I did a quick look, and I found that image filenames are changed.

Free Ebook: Machine Learning – A First Course for Engineers and Scientists

An interesting free ebook

When we developed the course Statistical Machine Learning for engineering students at Uppsala University, we found no appropriate textbook, so we ended up writing our own. It will be published by Cambridge University Press in 2021.

Andreas Lindholm, Niklas Wahlström, Fredrik Lindsten, and Thomas B. Schön

A draft of the book is available below. We will keep a PDF of the book freely available also after its publication.

Latest draft of the book (older versions >>)

Speeding Up Reinforcement Learning with a New Physics Simulation Engine

Source: https://ai.googleblog.com/2021/07/speeding-up-reinforcement-learning-with.html

Reinforcement learning (RL) is a popular method for teaching robots to navigate and manipulate the physical world, which itself can be simplified and expressed as interactions between rigid bodies1 (i.e., solid physical objects that do not deform when a force is applied to them). In order to facilitate the collection of training data in a practical amount of time, RL usually leverages simulation, where approximations of any number of complex objects are composed of many rigid bodies connected by joints and powered by actuators. But this poses a challenge: it frequently takes millions to billions of simulation frames for an RL agent to become proficient at even simple tasks, such as walking, using tools, or assembling toy blocks.
