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

然后你有一个解，它大致上是编的反向操作。

So that's called the encoder stage.

这就是编阶段。

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 模型的编将同时处理所有这些解析单元，以最终预测最佳字符和最佳单词。

Let's first explore the optical rotary encoder.

先来探索一光学旋转编。

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

顺便说一句，这在技术上称为增量正交编。

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或磁性旋转位置传感来测量旋转运动。

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.

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

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：光学编和磁性位置编。

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， 它有一个看起来像这样的圆盘，其中不同的角度有不同的部分打开以光线通过。

You input an A, and it might output a C. This may not sound like much, but you must know that the most powerful part of the Enigma is the core encryption part, the encoder's core is a gear.

您输入 A， 它可能会输出 C。 这听起来可能不多，但你必须知道 Enigma 最强大的部分是核心加密部分，编的核心是一个齿轮。
