一起来学习Pytorch相关术语

《一起来学习Pytorch相关术语》

Pytorch是一个优秀(illustrious)的深度学习库。

Tensors and Dynamic neural networks in Python with strong GPU acceleration.

深度学习中最重要的单位是:Tensor:

tensor在计算机中表示张量,也就是数量可以变化(向量长度可以伸缩)的向量。

而在生物中则表示:N any muscle that can cause a part to become firm or tense 张肌。

tense与tensor形似,当然意思也是有联系的,tense表示肌肉紧绷,即肌肉紧绷的意思,当然也可以表示情况紧张,心情焦虑。

dynamic /daɪˈnæmɪk/ CET4 TEM4

  • ADJ If you describe someone as dynamic, you approve of them because they are full of energy or full of new and exciting ideas. (人) 有活力的; 有创新思维的

    例:

    He seemed a dynamic and energetic leader.

    他看来是个富有创新力与活力的领导。

  • ADV 有活力地; 有创新思维地

    例:

    He’s one of the most dynamically imaginative jazz pianists of our time.

    他是我们这个时代最具活跃想像力的爵士乐钢琴演奏家之一。

  • ADJ If you describe something as dynamic, you approve of it because it is very active and energetic. (事物) 有活力的

    例:

    South Asia continues to be the most dynamic economic region in the world.

    南亚仍然是世界上最具活力的经济区。

  • ADJ A dynamic process is one that constantly changes and progresses. 动态的

    例:

    …a dynamic, evolving worldwide epidemic.

    …一次不断变化发展的、世界范围内的疾疫流行。

  • N-COUNT The dynamic of a system or process is the force that causes it to change or progress. 动力

    例:

    The dynamic of the market demands constant change and adjustment.

    市场的动力要求有不断的变化和调整。

  • N-PLURAL The dynamics of a situation or group of people are the opposing forces within it that cause it to change. (引发变革的) 反动力

    例:

    What is needed is insight into the dynamics of the social system.

    所需要的就是对社会制度反动力的洞悉。

dynamic,动态的,pytorch中使用的图为动态图,随建随用。

Autograd mechanics

自动求梯度机制

autograd => auto + grad(ient)

auto 作为一个单词来说是汽车的意思。但是作为前缀 auto- 代表自动地,这个单词的前缀就是auto 加上 gradient的其前半部分构成了新词autograd

grad作为单词来说是毕业生的意思,也可以叫硕士,是 graduate 毕业生的简写词。

gradient则是梯度的意思 N-COUNT A gradient is a slope, or the degree to which the ground slopes. 斜坡; 倾斜度。

我们来看看mechanic:

  • mechanic /mɪˈkænɪk/

    |CET6 TEM4

    • 1.

      N-COUNT A mechanic is someone whose job is to repair and maintain machines and engines, especially car engines. 机修工

      •  If you smell something unusual (gas fumes or burning, for instance), take the car to your mechanic.
       如果你闻到了异味(例如汽油味或燃烧味),就把车带给你的修理工。

    • 2.

      N-PLURAL Themechanicsof a process, system, or activity are the way in which it works or the way in which it is done. 运作方式

      •  What are the mechanics of this new process?
       这一新工序的运作方式是什么?

    • 3.

      N-UNCOUNT Mechanics is the part of physics that deals with the natural forces that act on moving or stationary objects. 力学

      •  He has not studied mechanics or engineering.
       他没有学习过力学或者工程学。

mechanics:力学(用作单数);结构;技术;机械学(用作单数)。

Broadcasting semantics

广播语法。pytorch可以实现类似于numpy的广播操作语法,即。

  • broadcast /ˈbrɔːdˌkɑːst/

    |CET4 TEM4 (broadcastingbroadcasts)

    • 1.

      N-COUNT A broadcast is a program, performance, or speech on the radio or on television. (无线电或电视) 广播节目

      •  In a broadcast on state radio the government announced that it was willing to resume peace negotiations.
       在国家电台的广播节目中,政府宣布愿意恢复和平谈判。

    • 2.

      V-T/V-I To broadcast a program means to send it out by radio waves, wires, or satellites so that it can be heard on the radio or seen on television. (由无线电或电视) 播放

      •  The concert will be broadcast live on television and radio.
       音乐会将通过电视和电台现场直播。

      •  CNN also broadcasts in Europe.
       美国有线新闻网络也在欧洲进行广播。

  • semantic /sɪˈmæntɪk/

    |TEM8

    • ADJ Semantic is used to describe things that deal with the meanings of words and sentences. 语义的

       He did not want to enter into a semantic debate.
       他不想卷入一场关于语义的争论。

       

  • bottleneck /ˈbɒtəlˌnɛk/

    |TEM4

    • 1.

      N-COUNT A bottleneck is a place where a road becomes narrow or where it meets another road so that the traffic slows down or stops, often causing traffic jams. 道路上的狭窄处

    • 2.

      N-COUNT A bottleneck is a situation that stops a process or activity from progressing. 瓶颈

      •  He pushed everyone full speed ahead until production hit a bottleneck.
       他敦促每个人全速前进,直到生产遇到瓶颈。

       

回顾

tensor 张量,张肌

dynamic 动态的

autograd 自动求梯度

gradient 梯度

mechanics 机制,技术

semantic 语义

bottleneck 瓶颈,障碍物
