Welcome everyone! Today, we're diving into the world of AI with Teachable Machine. This tool lets you train your computer to recognize images, sounds, or poses. Can anyone tell me what they think machine learning is?
Is it when computers learn from data?
Absolutely! In fact, think of it like teaching a dog to respond to commands. You show it what to do, and eventually, it learns how to respond. Now, can anyone remind me of the key steps in training a machine?
Collecting data, training the model, and then testing it!
Correct! Remember the acronym 'C-T-T' for Collect, Train, Test. That's how we'll approach our projects today. Let's move on to our first task!
Data Collection

Now that we understand the steps, let’s talk about data collection. Why do you think choosing the right data is crucial?
If we don't have good data, the model might not learn correctly!
Exactly! Quality data leads to better accuracy. When you select data for your model, consider its variety. Can anyone name types of data we can use?
Images, sounds, and text!
Great job! Let’s ensure we gather diverse samples for our projects. A tip—always label your data clearly! What strategies can we use to collect it?
We could take pictures ourselves or use online resources.
Good points! Using varied sources will enrich your dataset.
Building and Testing Models

Next, let’s discuss the training and testing phase of your models. Why is testing important after training?
To see if the model actually learned what we wanted it to!
Exactly! Testing reveals how well our model performs. It's like taking a quiz after studying. After testing, we may need to refine our models based on their performance. What might that involve?
Adjusting the data or retraining with different samples?
Correct! Always analyze your results before sharing your work. Finally, how can we share our findings in an engaging way?
We can create a presentation or a video!
Absolutely! Communication is key to sharing our AI projects effectively.
Linking AI to Sustainable Development Goals (SDGs)
🔒 Unlock Audio Lesson

Now let’s tie our projects to something critical—Sustainable Development Goals. Why do you think it’s important to relate our AI models to these goals?
To help solve real-world problems?
Exactly! This makes our work more meaningful. What are some local problems we could tackle?
Pollution or water wastage!
Great suggestions! Let's take a moment to create a 4Ws Problem Canvas for one of these issues. Who would like to start?
I can! For pollution, it's affecting local residents.
Perfect! You’re summarizing the 'who' part. These canvases will help us frame our AI projects more effectively.
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
In this section, students will utilize Teachable Machine and similar platforms to build basic AI models. They will learn the process of data training and testing, explore real-world problems linked to Sustainable Development Goals, and apply design thinking to devise creative AI solutions.
Detailed
Teachable Machine
This section focuses on using Teachable Machine, a user-friendly tool developed by Google, to build AI models. Students engage hands-on with the concepts of machine learning by choosing data types—images, sounds, or text—and then go through the steps of collecting data, training their models, testing them, and presenting their outputs. Additionally, the section emphasizes problem-solving in the context of Sustainable Development Goals (SDGs), encouraging students to identify local issues such as pollution or energy consumption and to develop AI-based solutions. The overall aim is to integrate creativity and technology, providing students with practical AI experience while enhancing their understanding of global challenges.

Chapter Content
Teachable Machine is a web-based tool by Google that allows anyone to train a model using images, sounds, or poses.
Detailed Explanation
Teachable Machine is an easy-to-use platform that helps you create machine learning models. You can provide different types of data, such as images, sounds, or body poses, and the tool will help you train a model to recognize and interpret that data. This means you can teach the machine to identify patterns based on what you show it, making it a hands-on way to learn about artificial intelligence.
Examples & Analogies
Think of Teachable Machine like training a pet. Just as you might teach a dog to recognize the command 'sit' by rewarding it every time it does the action, you are showing the machine examples and correcting it until it learns to recognize what each type of input (like a happy face or a clap) means.
Steps for Using Teachable Machine

Chapter Content
- Choose a type of data (Images/Text/Sound).
- Collect sample data for different classes.
- Train the model using the tool.
- Test and refine the model.
- Present the output and share your learning.
Detailed Explanation
Using Teachable Machine involves a few simple steps:
1. First, you need to decide which type of data you want to use: images, sounds, or text.
2. Next, you'll gather examples for different categories. For instance, if you choose images, you might collect photos of cats and dogs.
3. You then use these samples to train your model. During this training, the model learns to distinguish between the different classes based on the data you provided.
4. After training, it's time to test the model against new data to see how well it recognizes what it has learned. If it doesn't do well, you can refine it by adjusting your data or retraining it.
5. Finally, share your results! Present what you learned, the model's accuracy, and even how you might improve it further.
Examples & Analogies
Imagine you are a teacher preparing to evaluate students. First, you need to select a subject (like math or history). Then, you gather different tests (sample data) from students to check their knowledge. You evaluate and grade them (train the model), see which students need more help (testing), and finally, report back to the class about their progress and how they can improve.

Example Ideas
• Image Classifier: Recognize happy and sad faces.
• Sound Classifier: Differentiate claps, whistles, and snaps.
• Text Classifier: Identify positive or negative feedback.
Detailed Explanation
When using Teachable Machine, you can take on various fun projects. Here are some examples:
- Image Classifier: You could create a model that recognizes facial expressions, specifically happy and sad faces. This teaches you how machines interpret visual data.
- Sound Classifier: With sounds, you could train a model to distinguish between different sounds, like clapping, whistling, and snapping fingers, exploring audio data classification.
- Text Classifier: You might develop a model that can read and evaluate text, deciding whether the feedback is positive or negative. This involves understanding natural language processing.
Examples & Analogies
Think of these projects like organizing a party. If you want to put together a playlist, you might first identify happy songs versus sad songs (like recognizing emotions). For sound classification, it's like knowing how to cheer or clap differently based on the ambiance and who’s around. Finally, consider text classification as reading invitations; figuring out who is excited for the party versus those who can't make it or are indifferent.
