Embodiment 1
[0048] The environment used in this embodiment is GeForce GTX Titan X GPU, Inter Core i7-5930K, 3.50GHZ CPU, 64G RAM, linux operating system, using Python and open source library KERAS for development.
[0049] The first step is to divide the training data set and test data set:
[0050] Using the Mirflickr 25K image and audio data set, make 50,000 pairs of positive and negative sample image and audio pairs, and select 40,000 pairs as the training data set I train , and the remaining 10,000 pairs are used as the test data set I test ;
[0051] In the second step, pairs of pairs of samples are selected using the cross-modal pairing structure:
[0052] First construct N pairs of binary sample sets and the corresponding set of two-tuple labels Sample set of binary groups Consists of positive sample pairs and negative sample pairs, I i Indicates the i-th picture, V i Indicates the i-th audio, label y i ∈{0,1}, a label of 1 indicates that the image and audio are semantic...
