我们可以通过视频教一台机器吗？ [英] Can we teach a machine from video?

问题描述

您好b $ b是否有讨论过视频学习的书籍或文章？我知道我们可以通过照片教授神经网络，但视频呢？如何向机器教授动作？

Hi Is there any books or articles that discussed about learning from video? I know we can teach a neural network from photos, But what about videos? How can I teach an action to a machine?

推荐答案

请参阅我对这个问题的评论，这个问题过于宽泛。



如果您的问题是关于使用OpenCV，请从这里开始： http： //docs.opencv.org/modules/contrib/doc/facerec/tutorial/facerec_video_recognition.html [ ^ ]。



但是理解机器学习本身的基本原理是一件好事普通教育的一部分。

Please see my comment to the question, which is too broad.

If your question is about using OpenCV, please start here: http://docs.opencv.org/modules/contrib/doc/facerec/tutorial/facerec_video_recognition.html[^].

But understanding fundamentals of machine learning itself is a good portion of general education.

技术上讲一个视频并不是很多其他如果图像（帧）按顺序排列很多。因此，从图像中学习到视频之间没有太大区别（尽管您可以从视频中获得更多信息）。



但是你的问题不能很容易回答。如果你问AI爱好者他们可能会回答当然可以通过视频教一台机器。然而，这根本不是一件容易的事。事实上，这是一项全球研究的主题，花费了数百万美元，而且许多研究人员正在投入他们的（生命）时间来迈向自学机器。这不是下午工作可以实现的目标，但对于一些人来说，这也是他们一生奉献的目标。



如果你真的想工作在这个领域，你应该绝对清楚这意味着挑战。您可以尝试从纯互联网/书本学习中自行完成这项工作，但如果可能的话，我认为您应该考虑参加模式学习，机器学习，语言智能或类似方面的课程/学习。



首先，网上有很多资源，您可以通过以下关键词轻松找到：模式识别，机器学习，计算机视觉组合有教程或练习，例子等。其中只有一部分：

你也可以参加在线课程，例如

Coursera [ ^ ]。它们通常是免费的，并且对公众开放。



你也可以使用谷歌学者找到与该主题相关的科学出版物，如果你想要的话，这是关键的资源找出最近在这个领域取得了哪些进展：

Technically speaken a video is not much else then a lot if images (frames) in sequence. So there is not much difference between "learning" from an image then from a video (despite some more information you may obtain from the video).

Your question however cannot be answered easily. If you ask AI enthusiasts they would probably answer of course it's possible to "teach" a machine from a video. However this is not an easy task at all. In fact it is a topic of worldwide research which several million (billion) of dollars are spend on and many researchers are investing their (life)time to make some steps towards a self learning machine. This is no goal which can be achieved during an afternoons work, but for some it is an aim which they dedicate their whole life too.

If you really want to work in this field you should be absolutely clear about the challenge this implies. You can try to do this on your own from pure internet / book learning but if possible in any way in my opinion, you should consider taking courses / studies in the field of pattern learning, machine learing, articifial intelligence or similar.

For the start there are many ressources online which you can find fairly easy with the keywords: "pattern recognition", "machine learning", "computer vision" in combination with tutorial or excercise, examples and so on. Just some of them:
- http://www.r-bloggers.com/in-depth-introduction-to-machine-learning-in-15-hours-of-expert-videos/[^]
http://fastml.com/machine-learning-courses-online/[^]

You could as well take part in online courses, that are offered e.g.
on Coursera[^]. They are usually free and open to public access.

You can also use google scholar to find scientific publications related to the topic, which are the key ressource if you want to find out which progress is made in this field recently:
