A lecture example describes an effort to identify early warning signs of lung cancer in x-rays, contrasted with a separate mishap the instructor called an ‘oopsie.’ That mishap is specifically attributed to which type of learning, where the system was left to find its own patterns without labeled outcomes to guide it?

Problem 1 (10 pts) A three-phase uncontrolled bridge rectifier supplies an RL load with continuous current. The average output voltage is 540 V, and the load resistance is 30 ohms. Assume ideal diodes and negligible source inductance. (a) Determine the average load current, I0. (1 pt) (b) Based on the Fourier-series representation of the AC source current, determine the following: (5 pts) The peak amplitude of the fundamental current component. The orders and peak amplitudes of the first two nonzero harmonic current components. The total harmonic distortion (THD) of the AC source current. Now replace the uncontrolled bridge rectifier with a three-phase fully controlled bridge rectifier. The source line-to-line RMS voltage is 480 V, and the load resistance remains 30 ohms. Assume ideal SCRs, continuous current, and negligible source inductance. (c) Determine the firing angle
