Then you have a decoder, which roughly speaking is the encoder in reverse.

然后你有一个解码器，它大致上是编码器的反向操作。

So that's called the encoder stage.

就是编码阶段。

Premiere Photoshop, Lightroom and Media Encoder are all running natively on Apple Silicon.

Premiere Photoshop、Lightroom 和 Media Encoder 都在 Apple Silicon 上本地运行。

The encoder of the transformer is going to process all of these tokens simultaneously to predict the best character and the best word eventually.

Transformer 模型的编码器将同时处理所有解析单元，以最终预测最佳符和最佳单词。

Let's first explore the optical rotary encoder.

先来探索一下光学旋转编码器。

By the way, this is technically called an incremental  quadrature encoder.

顺便说一句，在技术上称为增量正交编码器。

Scroll wheels commonly use either optical rotary  encoders or magnetic rotary position sensors in order to measure rotational motion.

滚轮通常使用光学旋转编码器或磁性旋转位置传感器来测量旋转运动。

The key to the optical rotary encoder is that, as the wheel is rotated, the light emitted from  the IR LED is intermittently blocked by the encoding disk.

光学旋转编码器的关键在于，当轮子旋转时， 红外 LED 发出的光会被编码盘间歇性地阻挡。

First, the incremental optical encoder from earlier can't read out an absolute angular  position because the wheel has 48 equally spaced spokes, and it can't discern one angle from the  next.

首先， 早期的增量式光学编码器无法读出绝对角度位置， 因为车轮有 48 个等距辐条，并且无法区分一个角度和下一个角度。

One thing to note is that in this video we covered just two methods to measure rotational motion: an  optical encoder and a magnetic position encoder.

需要注意的一点是，在本视频中，只介绍了两种测量旋转运动的方法：光学编码器和磁性位置编码器。

However, it is possible to have an absolute optical encoder which has a disk that looks  like this, where different angles have different sections open to let the light through.

然而， 可以有一个绝对光学编码器， 它有一个看起来像样的圆盘，其中不同的角度有不同的部分打开以光线通过。
