Hierarchical Attention-Based Fusion for Image Caption With Multi-Grained Rewards
Image caption based on reinforcement learning (RL) methods has achieved significant success recently. Most of these methods take CIDEr score as the reward of reinforcement learning algorithm to compute gradients, thus refining the image caption baseline model. However, CIDEr score is not the sole cr...
