You have reached the end of this crash course on classifying images with machine learning. You should now have a better understanding of how machine learning works in practice, as well as what its power and limitations are.
If you have previously taken our Introduction to Machine Learning, you now have the perfect toolkit to understand how to enhance your reporting with machine learning and how you can make the most, in a responsible way, of the power offered by these technologies.
Let's recap all the steps involved in training a machine learning model:
- Reflect on your use case and consider whether ML can be (part of) the solution to the problem you are trying to solve.
- Source the data you need and take every possible step to minimise the potential impact of biases in the data.
- Clean and prepare the data so that it contains the right balance of information the model needs to learn from.
- Choose the algorithm that is best suited to meet the goals of your use case and the features of your training data.
- Upload the dataset you prepared to the algorithm of your choice and wait for it to learn.
- Evaluate the results and decide if they are good enough to use the model for your journalistic purpose. If not, repeat.
In this crash course, we learned how machine learning can be used to classify images in the context of an investigation, but there are many other journalistic use cases. Find a few examples in this handy collection by the Quartz AI Studio that highlights instances of "how you might feel when machine learning can help".
If you want to know more about how news organisations use machine learning and other AI-powered technologies, browse the ever-growing library of case studies curated by the JournalismAI team.
And never forget to carefully reflect on how to identify potential biases in your data and make sure that they are not replicated and multiplied by your ML model. Check out this Google Cloud guide on Inclusive ML to learn more.
