Google 於昨天宣布將在 MOOC 供應商Udacity上推出機器深度學習課程。簡單的講，課程將涉及使用大量數據對人工神經網絡進行培訓，即讓機器在現有知識的基礎上根據新數據進行推斷和學習。
Google Brain 團隊首席科學家和技術領頭人Vincent Vanhoucke將在 Udacity 上講授該門課程。Google Brain 研發團隊掌握著 Google 的核心深度學習技術，這些技術也被用在 Google 的許多產品中。據了解，機器深度學習技術一直被用於多款 Google 產品中，其中包括 Google 語音搜素，Gmail Inbox 功能，Google 照片和 Google 翻譯。
在去年11月，Google 開源了人工智慧學習系統 TensorFlow 系統。據悉，TensorFlow 是 Google Brain 團隊開發的一款深度學習軟體。根據 Vanhoucke 在博客中公布的課程信息我們可以確定，Google 在 Udacity 中開設的課程將包括 TensorFlow 研發，以及 CNN 卷積神經網絡、RNN 循環神經網絡、LSTM 網絡教程。
Google 在博客中發布了課程公告，目前已經有 100 萬人註冊了 Google 在 Udacity 上發布的開發者培訓課程。與開源後的 TensorFlow 軟體一樣，此次開放的深度學習課程將全程免費。
Vanhoucke 在博客中寫到：「我們開放深度學習課程的目的是為機器深度學習的愛好者們提供一條快捷解決機器深度學習技術實操問題的途徑。我們非常樂意與公眾分享 Google 目前在這個領域的研究成果」。
據了解，Google目前已經在 Udacity 開設了包括安卓應用開發、網頁開發、雲計算和科技創業為主題的課程版塊。
不僅 Udacity，其他的 MOOC 機構也推出了類似的課程。例如，在線學習網站Coursera就在日前推出了由百度首席科學家 Andrew Ng 主講的機器學習課程。
Google launches a deep learning course on Udacity來自http://venturebeat.com/2016/01/21/google-launches-a-deep-learning-course-on-udacity/
Google today announced that it’s bringing a deep learning course to massively open online course (MOOC) provider Udacity.
Deep learning is an increasingly popular type of artificial intelligence. Generally speaking, it involves training artificial neural networks on lots of data — like pictures — and then getting them to make inferences about new data based on what they know.
Vincent Vanhoucke, a Google principal scientist and a technical lead on the Google Brain team, is teaching the course, which is part of Udacity’s machine learning engineer Nanodegree program. The Google Brain team advances the company’s core deep learning technology, which can be used inside of many Google products.
Indeed, Google uses deep learning in many of its applications, including Google Voice Search, Inbox by Gmail, Google Photos, and Google Translate.
In November, Google open-sourced TensorFlow, a powerful piece of deep learning software from the Google Brain team. And sure enough, the Udacity course will cover TensorFlow, as well as convolutional neural networks, recurrent neural networks, and long short term memory networks, Vanhoucke wrote in a blog post on the news.
「Our overall goal in designing this course was to provide the machine learning enthusiast a rapid and direct path to solving real and interesting problems with deep learning techniques, and we’re now very excited to share what we』ve built!」 Vanhoucke wrote.
The course itself is free — just like the TensorFlow software.
Udacity competitor Coursera offers a machine learning course from deep learning luminary (and former Google Brain team member) Andrew Ng.
Separately, Google announced in a blog post today that 1 million people have now enrolled in the Google Developer Training courses available through Udacity.
