I found this definition of RI:

Rapid intensification, also known as RI, is roughly defined by the NHC as an "increase in the maximum sustained winds of a tropical cylcone of at least 30 kt in a 24-hour period." While it is commonly believed that rapid intensification only occurs with more stronger storms, rapid intensification can occur regardless of the storm strength. Rapid intensification is often coupled with a rapid decrease in a storm's minimum pressure, and thus RI is also known as rapid deepening. However, the NHC maintains its own definition of rapid deepening, which would be a drop of 1.75 mbar/hour or 42 mbars in a day.

Technically, Joaquin has undergone RI but not rapid deepening.
