Same here. Machine learning wasn&#x27;t in vogue when I graduated, but now I&#x27;m actually able to help my younger brother through the last courses in college. Quite surprising, because I&#x27;d have sworn when I was that age it would take weeks to understand something like Random Forest.<p>I reckon part of the reason is that when there&#x27;s no pressure on you, you can explore around a question (how do you classify this particular thing...) rather than try to steer right towards the answer as fast as possible. Which isn&#x27;t actually as fast as when you read around.
