-ML models don't give a binary answer, instead they give probabilities. For example, a model may be given a picture of a strawberry and predict `ripe` at 99.7% and `unripe` at 0.3%. Your code would then pick the best prediction and decide the strawberry is ripe.

 The ML model used to detect images like this is called an *image classifier* - it is given labelled images, and then classifies new images based off these labels.
 
 ## Train an image classifier
 
-To successfully train an image classifier you need millions of images. As it turns out, once you have an image classifier trained on millions or billions of assorted images, you can re-use it and re-train it using a small set of images and get great results, using a process called transfer learning.

+
+> 🎓 Transfer learning is where you transfer the learning from an existing ML model to a new model based off new data.
 
 Once an image classifier has been trained for a wide variety of images, it's internals are great at recognizing shapes, colors and patterns. Transfer learning allows the model to take what it has already learned in recognizing image parts, and use that to recognize new images.
 
 ![Once you can recognize shapes, they can be put into different configurations to make a boat or a cat](../../../images/shapes-to-images.png)
 
-You can think of this as a bit like children's shape books, where once you can recognize a semi-circle, a rectangle and a triangle, you can recognize a sailboat or a cat depending on the configuration of these shapes. The image classifier can recognize the shapes, and the transfer learning teaches it what combination makes a boat or a cat - or a ripe strawberry.

The image classifier can recognize the shapes, and the transfer learning teaches it what combination makes a boat or a cat - or a ripe banana.
 
 There are a wide range of tools that can help you do this, including cloud-based services that can help you train your model, then use it via web APIs.
 
-> 💁 Training these models takes a lot of computer power, usually via Graphics Processing Units, or GPUs. The same specialized hardware that makes graphics on your Xbox look amazing can also be used to train machine learning models. By using the cloud you have access to the power you need, just for the time you need it.

 ## Custom Vision
 
 Custom Vision is a cloud based tool for training image classifiers. It allows you to train a classifier using only a small number of images. You can upload images through a web portal, web API or an SDK, giving each image a *tag* that has the classification of that image. You then train the model, and test it out to see how well it performs. Once you are happy with the model, you can publish versions of it that can be accessed through a web API or an SDK.
 
+> 💁 You can train a custom vision model with as little as 5 images per classification, but more is better. You can get better results with at least 30 images.
+
 Custom Vision is part of a range of AI tools from Microsoft called Cognitive Services. These are AI tools that can be used either without any training, or with a small amount of training. They include speech recognition and translation, language understanding and image analysis. These are available with a free tier as services in Azure.
 
 > 💁 The free tier is more than enough to create a model, train it, then use it for development work. You can read about the limits of the free tier on the [Custom Vision Limits and quotas page on Microsoft docs](https://docs.microsoft.com/azure/cognitive-services/custom-vision-service/limits-and-quotas?WT.mc_id=academic-17441-jabenn).

 Ideally each picture should be just the fruit, with either a consistent background, or a wide variety of backgrounds. Ensure there's nothing in the background that is specific to ripe vs unripe fruit.

It turned out the classifier was 100% accurate at identifying rulers in pictures.
+
+1. Gather pictures for your classifier. You will need at least 5 pictures for each label to train the classifier, but the more the better. You will also need a few additional images to test the classifier. These images should all be different images of the same thing. For example:
+
+    * Using 2 ripe bananas, take some pictures of each one from a few different angles, taking at least 7 pictures (5 to train, 2 to test), but ideally more.
+
+        ![Photos of 2 different bananas](../../../images/banana-training-images.png)
+
+    * Repeat the same process using 2 unripe bananas
+
+    You should have at least 10 training images, with at least 5 ripe and 5 unripe, and 4 testing images, 2 ripe, 2 unripe. You're images should be png or jpegs, small than 6MB. If you create them with an iPhone for example they may be high-resolution HEIC images, so will need to be converted and possibly shrunk. The more images the better, and you should have a similar number of ripe and unripe.
+
+    If you don't have both ripe and unripe fruit, you can use different fruits, or any two objects you have available. You can also find some example images in the [images](./images) folder of ripe and unripe bananas that you can use.

 ## Test your image classifier
 
+Once your classifier is trained, you can test it by giving it a new image to classify.

 ### Task - test your image classifier
 
+1. Follow the [Test and retrain a model with Custom Vision Service documentation on the Microsoft docs](https://docs.microsoft.com/azure/cognitive-services/custom-vision-service/test-your-model?WT.mc_id=academic-17441-jabenn#test-your-model) to test your image classifier.

+
+    ![A unripe banana predicted as unripe with a 98.9% probability, ripe with a 1.1% probability](../../../images/banana-unripe-quick-test-prediction.png)
+
+1. Try all the testing images you have access to and observe the probabilities.
+

 ## 🚀 Challenge
 
+Image classifiers use machine learning to make predictions about what is in an image, based of probabilities that particular features of an image mean that it matches a particular label. It doesn't understand what is in the image - it doesn't know what a banana is or understand what makes a banana a banana instead of a boat.
+
+What do you think would happen if you used a picture of a strawberry with a model trained on bananas, or a picture of an inflatable banana, or a person in a banana suit, or even a yellow cartoon character like someone from the Simpsons?
+
+Try it out and see what the predictions are.
