Function composition is the process of combining multiple functions to create a new, cohesive workflow. This involves defining the inputs and outputs of each function and how they interact with each other. The design of these functions is crucial for both the user experience and the model’s ability to generate the correct output.

Finding the Perfect Car

  1. Drive cross-country, quickly and reliably, twice a year.
  2. Seat 6+ people fairly often.
  3. REAL off-road capability.
  4. Excellent driver assist/“self driving” technology.
