Provided is an oscillator including: a first resonator; a second resonator; a first oscillation circuit generating a first oscillation signal by oscillating the first resonator; a second oscillation circuit generating a second oscillation signal that has frequency-temperature characteristics different from frequency-temperature characteristics of the first oscillation signal by oscillating the second resonator; a clock signal generation circuit generating a clock signal with a frequency that is temperature compensated by temperature compensation data; a storage unit storing information on a learned model that is machine-learned to output data corresponding to the temperature compensation data with respect to input data; and a processing circuit obtaining the temperature compensation data by performing processing based on the information on the learned model with respect to the input data based on the first oscillation signal and the second oscillation signal.
