- Convolutional networks have shown advantages on machine translation and conditional image generation.
Innovation:
- The authors develop a convolutional ( CNN-based ) image captioning method that shows comparable performance to an LSTM based method on standard metrics.
- The authors analyze the characteristics of CNN and LSTM nets and provide useful insights such as -- CNNs produce more entropy ( useful for diverse predictions ), better classification accuracy, and do not suffer from vanishing gradients.
Improvement:
- Improved performance with a CNN model that uses Attention Mechanism to leverage spatial image features.
General Points:
- Image Captioning is applicable to virtual assistants, editing tools, image indexing and support of the disabled.
- Image Captioning is a basic ingredient for more complex operations such as storytelling and visual summarization.
- An illustration of a classical RNN architecture for image captioning is provided below.
