Many machine learning tasks such as multiple instance learning, 3D shape recognition, and few-shot image classification are defined on sets of instances.
View-based approach that recognizes 3D shape through its projected 2D images has achieved state-of-the-art results for 3D shape recognition.
Each state of the beam search corresponds to a candidate CNN.
In this network, a Score Generation Unit is devised to evaluate the quality of each projected image with score vectors.
