3.3 History Generation via Multimodal Self Summarization
Set-of-Mark prompting bridges the gap between text outputs from GPT-4V and executable localized actions. However, the agent’s ability to maintain a Table 1: Zero-shot GPT-4V iOS screen navigation accuracy on the “intended action description” and “localized action execution” tasks, respectively.
historical context is equally important in successfully completing tasks on smartphones. The key difficulty lies in devising a strategy that allows the agent to effectively determine the subsequent action at each stage of an episode, taking into account both its prior interactions with the environment and the present state of the screen. The naive approach of feeding all historical screens or actions into the agent is computationally expensive and may decrease the performance due to information overload. For example, screens at each step can change rapidly, and most of the historical screen information is not useful for reasoning about future actions. Humans, on the other hand, can keep track of a short memory of the key information after performing a sequence of actions. We aim to find a more concise representation than a sequence of screens or actions. Specifically, at each time step, we ask GPT-4V to perform multimodal self summarization, which converts the historical actions and current step information into a concise history in the form of natural language, which is formulated as follows:
