什么是可教学机？ (What is Teachable Machine?)

Teachable Machine is a web-based tool that makes creating machine learning models fast, easy, and accessible to everyone. You train a computer to recognize your images, sounds and poses without writing any machine learning code. Then, use your model in your own projects, sites, apps, and more. Anyone can use this like Educators, artists, students, innovators, makers of all kinds — really, anyone who has an idea they want to explore.

Teachable Machine是一个基于Web的工具，可让每个人快速，轻松地访问机器学习模型。 您训练计算机无需编写任何机器学习代码即可识别图像，声音和姿势。 然后，在您自己的项目，网站，应用程序等中使用您的模型。 任何人都可以使用此工具，例如教育者，艺术家，学生，创新者，各种创造者-确实，任何有想法要探索的人。

如何使用？ (How do I use it?)

1)收集数据： (1) Gather Data:)

You can currently train Teachable Machine with images (pulled from your webcam or image files), sounds (in one-second snippets from your mic), and poses (where the computer guesses the position of your arms, legs, etc from an image). More types of training may be coming soon :)

当前，您可以使用图像(从网络摄像头或图像文件中拉出)，声音(麦克风中的一秒钟片段)和姿势(计算机从图像中猜测手臂，双腿等的位置)训练可教机。 更多类型的培训可能即将推出:)

2)火车模型： (2) Train Model:)

Train your model by just clicking a single button no need for any smoothing or pre-processing required, Teachable Machine will train a model based on the examples you provided. All the training happens in your browser, so everything stays on your computer. then instantly test it out to see whether it can correctly classify new examples like poses, voice, or images as per prior input which used for training.

只需单击一个按钮即可训练模型，而无需进行任何平滑或预处理，Teachable Machine将根据您提供的示例训练模型。 所有培训都在您的浏览器中进行，因此所有内容都保留在您的计算机上。 然后立即对其进行测试，以查看其是否可以根据用于训练的先前输入正确地对姿势，语音或图像等新示例进行分类。

3)出口模式： (3) Export Model:)

There are a few ways to save your work. You can:

有几种方法可以保存您的工作。 您可以：

1. Save your entire project to Google Drive. You can save your project to your Google Drive. This saves a .zip file that contains all the samples in each of your classes to Drive. You can then open that .zip again from Teachable Machine later to pick up where you left off.

   将整个项目保存到Google云端硬盘 。 您可以将项目保存到Google云端硬盘。 这样会将包含每个类中所有示例的.zip文件保存到云端硬盘。 然后，您可以稍后从Teachable Machine中再次打开该.zip，以从上次中断的地方继续。

2. Download your samples. You can download all the samples in each class, and upload them later if you want to keep working with the same data.

   下载样本 。 您可以下载每个类中的所有样本，如果想继续使用相同的数据，可以稍后再上传。

3. Download your model. If you download your model and close your tab, you can use that downloaded model later — and nothing is saved on any servers.

   下载模型 。 如果下载模型并关闭选项卡，则以后可以使用该下载的模型-任何服务器上都不会保存任何内容。

4. Save nothing. If you close your tab and do none of the above, nothing is saved in your browser or on any servers.

   什么都不存 。 如果关闭选项卡，但不执行上述任何操作，则不会在浏览器或任何服务器上保存任何内容。

背面如何运作？ (How does it work on the back?)

Teachable Machine uses TensorFlow.js, a library for machine learning in Javascript, to train and run the models you make in your web browser.

Teachable Machine使用TensorFlow.js (一个使用Javascript进行机器学习的库)来训练和运行您在Web浏览器中创建的模型。

These models use a technique called transfer learning. There’s a pre-trained neural network, and when you create your own classes, you can sort of picture that your classes are becoming the last layer or step of the neural net. Specifically, both the image and pose models are learning off of pre-trained mobile net models, and the sound model is built on Speech Command Recognizer.

这些模型使用一种称为转移学习的技术。 有一个预先训练的神经网络，当您创建自己的类时，您可以看到类正在成为神经网络的最后一层或最后一步的图片。 具体来说，图像和姿势模型都是从预先训练的移动网络模型中学习的，而声音模型是基于语音命令识别器构建的。

Set-Up Adafruit Circuit Playground Express (CPX):

设置Adafruit Circuit Playground Express(CPX)：

You can re-compile the code for any SAMD21/SAMD51/nRF52840 chipset that Adafruit supports with TinyUSB. That’s because we have to use WebUSB to communicate and that’s not easy to do with Arduino.

您可以为TinyUSB支持Adafruit支持的任何SAMD21 / SAMD51 / nRF52840芯片组的代码。 那是因为我们必须使用WebUSB进行通信，而使用Arduino并不容易。

The first thing you will need to do is to download the latest release of the Arduino IDE. Download Arduino IDE using below https://www.arduino.cc/download_handler.php

您需要做的第一件事是下载最新版本的Arduino IDE。 使用以下https://www.arduino.cc/download_handler.php下载Arduino IDE

安装所有必需的库和板文件 (Install All Required Libraries and Board Files)

First, We need to import all the Adafruit libraries and Board Files. In the Arduino IDE menus, go to File -> Preferences and paste this URL in Additional Boards Manager URLs: https://www.adafruit.com/package_adafruit_index.json

首先，我们需要导入所有Adafruit库和Board文件。 在Arduino IDE菜单中，转到文件->首选项，然后将此URL粘贴到其他板管理器URL中： https : //www.adafruit.com/package_adafruit_index.json

Second, We need to download the required board files. In the Arduino IDE menus, go to Tools -> Board -> Board Manager. Search for Adafruit SAMD Boards. If you are using nRF52840 chipset Search for Adafruit nRF52840.

其次，我们需要下载所需的电路板文件。 在Arduino IDE菜单中，转到工具->板->板管理器。 搜索Adafruit SAMD板。 如果您使用的是nRF52840芯片组，请搜索Adafruit nRF52840。

Third, We need to install the libraries. In the Arduino IDE menus, go to Sketch -> Include Library -> Manage Libraries. Search for Adafruit TinyUSB Library & Adafruit NeoPixel library. Now we download the Web USB library. Now go to Sketch -> Include Library -> Add .Zip Library and locate the webUSB library folder and Import it.

第三，我们需要安装库。 在Arduino IDE菜单中，转到Sketch- > Include Library- > Manage Libraries。 搜索Adafruit TinyUSB库和Adafruit NeoPixel库。 现在我们下载Web USB库 。 现在转到Sketch- > Include Library- > Add .Zip Library并找到webUSB库文件夹并将其导入。

Finally, Connect your CPX to your computer via a known, good USB cable (not a charger “power only” cable, please). go to Tools -> USB Stack, and select TinyUSB. If this is not selectable, update your version of the Arduino IDE. Switching the USB stack puts in TinyUSB instead of the default Arduino USB stack. TinyUSB has more features including WebUSB support.

最后，通过已知的优质USB电缆(请不要使用充电器的“仅电源”电缆)将CPX连接到计算机。 转到工具 -> USB堆栈，然后选择TinyUSB 。 如果无法选择，请更新您的Arduino IDE版本。 切换USB堆栈会放入TinyUSB，而不是默认的Arduino USB堆栈。 TinyUSB具有更多功能，包括WebUSB支持。

If you have these settings selected you can proceed with the coding.

如果选择了这些设置，则可以继续进行编码。

Now you can connect your device to P5.js webpage using Chrome WebUSB

Class 1: Eg(Collection of images of a masked man) This class lets the classifier know when there a masked man in front of the camera thus it should take any action.

第1类：例如，(蒙面男子的图像集合)此类可让分类器知道相机前面是否有蒙面男子，因此应该采取任何措施。

Class 2: Eg(Collection of images of unmasked man) This class lets the classifier know when there an unmasked man in front of the camera thus it should take any action.

第2类 ：例如，(未蒙面男子的图像集合)此类可让分类器知道摄像头前面何时有未蒙面男子，因此应采取任何措施。

Empty: Eg(Collection of images where there is no man) This class lets the classifier know when there is no one in front of the camera thus it should not take any action until there is something identifiable.

空 ：例如(没有人的地方的图像集合)此类可让分类器知道何时没有人在相机前，因此，除非有可识别的东西，否则它不应采取任何行动。

Now click on Train Model and that’s it! You’ve trained a model.

现在单击火车模型 ，就是这样！ 您已经训练了一个模型。

获取模型共享链接 (Get the Model Sharable Link)

Click Export Model and then click Upload my model to cloud.

将Arduino Leonardo连接到P5.js Web编辑器页面 (Connect the Arduino Leonardo to P5.js Web editor Page)

Ensure your Arduino Leonardo is still connected to your computer via a USB cable.

确保您的Arduino Leonardo仍通过USB电缆连接到计算机。

1. Open this P5 editor in new chrome tab在新的Chrome标签中打开此P5编辑器

2. P5 Editor: https://editor.p5js.org/Jude_Raj/present/B-KOSb1Ub

   P5编辑器： https ： //editor.p5js.org/Jude_Raj/present/B-KOSb1Ub

3. Click Connect Arduino, Select the board listed, and click connect. Similar to the below image.

   单击连接Arduino，选择列出的板，然后单击连接。 类似于下图。

训练模型 (Train the Model)

Try to get somewhere between 75–150 pictures per class. Remember the more accurate data your model has the better it will be.

尝试每堂课获得75-150张图片。 请记住，模型越准确，数据越好。

Train Class 1, Class 2, and a Empty Class (Refer How to use it? from above paragraph).

训练1 类，2类和空 类(请参阅上段的“ 如何使用它？” ) 。

Class 1: Eg(Collection of images of a masked man) This class lets the classifier know when there a masked man in front of the camera thus it should take any action.

第1类：例如，(蒙面男子的图像集合)此类可让分类器知道相机前面是否有蒙面男子，因此应该采取任何措施。

Class 2: Eg(Collection of images of unmasked man) This class lets the classifier know when there an unmasked man in front of the camera thus it should take any action.

第2类 ：例如，(未蒙面男子的图像集合)此类可让分类器知道摄像头前面何时有未蒙面男子，因此应采取任何措施。

Empty: Eg(Collection of images where there is no man) This class lets the classifier know when there is no one in front of the camera thus it should not take any action until there is something identifiable.

空 ：例如(没有人的地方的图像集合)此类可让分类器知道何时没有人在相机前，因此，在有可识别的东西之前，它不应采取任何措施。

Now click on Train Model and that’s it! You’ve trained a model.

现在单击火车模型 ，就是这样！ 您已经训练了一个模型。

获取模型共享链接 (Get the Model Sharable Link)

Click Export Model and then click Upload my model to cloud.

单击导出模型 ，然后单击将我的模型上传到云。

Now you will get Your sharable link. Copy the link, go-to P5 editor, and paste in the link and click LOAD MODEL.

现在，您将获得您的可共享链接。 复制链接，转到P5编辑器，然后粘贴链接，然后单击“ 加载模型”。

就这样，现在您可以使用Teachable Machine创建自定义分类模型，并使用Arduino Leonardo根据预测的类采取行动 (That’s it, Now you can create custom classification models using Teachable Machine and take action based on the predicted class using Arduino Leonardo)
