I love listening to music with my daughters. One minute it might be a Disney classic, the next some pop song off the radio. What interests me is when I introduce something new to see the response. Each decision influences the next choice. This rather than sandwiches captures the challenges and complexities associated with ‘algorithms’ and ‘machine learning’.
I have lost count the amount of times that the art of making a sandwich has been used as the ultimate example of human algorithms. Although I agree it can be useful, I do not think that it provides the nuance for appreciating machine learning. For me this comes in the form of music.
