  We demonstrate the application of a convolutional neural network to the
gravitational wave signals from core collapse supernovae. Using simulated time
series of gravitational wave detectors, we show that based on the explosion
mechanisms, a convolutional neural network can be used to detect and classify
the gravitational wave signals buried in noise. For the waveforms used in the
training of the convolutional neural network, our results suggest that a
network of advanced LIGO, advanced VIRGO and KAGRA, or a network of LIGO A+,
advanced VIRGO and KAGRA is likely to detect a magnetorotational core collapse
supernovae within the Large and Small Magellanic Clouds, or a Galactic event if
the explosion mechanism is the neutrino-driven mechanism. By testing the
convolutional neural network with waveforms not used for training, we show that
the true alarm probabilities are 52% and 83% at 60 kpc for waveforms R3E1AC and
R4E1FC L. For waveforms s20 and SFHx at 10 kpc, the true alarm probabilities
are 70% and 93% respectively. All at false alarm probability equal to 10%.
