The jet-black tree-shadows were so wonderfully distinct and substantial looking, I often stepped high in crossing them, taking them for black charred logs.

乌黑的树影分明而有质感，我常常高高地跨过它们，以为它们是黑色的焦木。

So each algorithm has parameters that we can modify to optimize the accuracy. So these are the high level steps that you follow in a machine learning project. Next we'll look at the libraries and tools for machine learning.
