Core Concepts
A novel framework that integrates visual attention prompts into the decision-making process of deep neural networks to enhance their predictive capabilities, while also addressing challenges posed by incomplete prompts and samples without prompts.
Abstract
The paper introduces a Visual Attention-Prompted Prediction and Learning framework that aims to effectively integrate visual attention prompts into the decision-making process of deep neural networks. The key highlights and insights are:
Attention-Prompted Prediction Framework:
The framework utilizes visual attention prompts to guide the model's reasoning process, allowing the model to focus on "indispensable", "precluded", and "undecided" areas of the input image.
Attention-Prompted Co-Training Mechanism:
To handle samples without prompts, the framework employs a co-training approach that aligns the parameters and activations of a prompted model and a non-prompted model, enabling knowledge transfer.
This allows the non-prompted model to benefit from the reasoning guided by the attention prompts.
Attention Prompt Refinement:
To address the challenge of incomplete prompts, the framework proposes a novel architecture that learns to refine the incomplete prompts by aligning them with the model's own post-hoc explanations.
This enables the model to effectively utilize the available partial information in the prompts.
Comprehensive Experiments:
The framework is evaluated on four datasets, including real-world scenarios and medical imaging tasks, demonstrating its effectiveness in enhancing predictive performance for samples with and without attention prompts.
The results show that the proposed framework outperforms various attention-guided learning methods across multiple evaluation metrics.
Overall, the Visual Attention-Prompted Prediction and Learning framework provides a novel and effective approach to leveraging visual attention prompts to guide and enhance the decision-making process of deep neural networks, while also addressing the challenges of incomplete prompts and samples without prompts.
