How Well Does GPT-4V(ision) Adapt to Distribution Shifts? A Preliminary Investigation

Abstract: In machine learning, generalization against distribution shifts -- where deployment conditions diverge from the training scenarios -- is crucial, particularly in fields like climate modeling, biomedicine, and autonomous driving. The emergence of foundation models, distinguished by their extensive pretraining and task versatility, has led to an increased interest in their adaptability to distribution shifts. GPT-4V(ision) acts as the most advanced publicly accessible multimodal foundation model, with extensive applications across various domains, including anomaly detection, video understanding, image generation, and medical diagnosis. However, its robustness against data distributions remains largely underexplored. Addressing this gap, this study rigorously evaluates GPT-4V's adaptability and generalization capabilities in dynamic environments, benchmarking against prominent models like CLIP, LLaVA, and Gemini. We delve into GPT-4V's zero-shot generalization across 13 diverse datasets spanning natural, medical, and molecular domains. We further investigate its adaptability to controlled data perturbations and examine the efficacy of in-context learning as a tool to enhance its adaptation. Our findings delineate GPT-4V's capability boundaries in distribution shifts, shedding light on its strengths and limitations across various scenarios. Importantly, this investigation contributes to our understanding of how AI foundation models generalize to distribution shifts, offering pivotal insights into their adaptability and robustness.

Overview of GPT-4V(ision) Adaptability

In the field of AI, robustness against data distribution shifts remains a critical quality, particularly in high-impact areas like medical diagnosis and autonomous driving. Models must generalize well—meaning they should perform consistently when presented with new, unseen data. The emergence of sophisticated foundation models has garnered attention for their extensive pretraining and task versatility. Among these, GPT-4V(ision) stands as a flagship multimodal model, yet its robustness to shifts in data distribution has been insufficiently tested.

Zero-Shot Generalization Abilities

GPT-4V was evaluated for zero-shot generalization, which is the model's ability to accurately interpret and respond to data it has not been explicitly trained on. Benchmarked against other models like CLIP and LLaVA, GPT-4V was examined across 13 datasets encompassing natural images, medical images, and scientific visuals. Notably, while GPT-4V exhibited strong adaptability across natural datasets, it faced challenges with specialized domains like medical imaging and molecular data.

Response to Induced Distribution Shifts

To further challenge GPT-4V, the study introduced variations in the datasets by adding Gaussian noise and employing ControlNet to generate domain shifts. The model's performance suggested an impressive resilience. GPT-4V consistently outperformed the benchmarks when dealing with deliberately altered data, indicating a strong ability to generalize under controlled perturbations.

Efficacy of In-Context Learning

In lieu of the conventional fine-tuning approach, researchers explored in-context learning as a potent tool to improve GPT-4V's proficiency in unfamiliar domains. In-context learning involves providing models with a context or examples to infer and apply learned patterns. The study found noticeable performance improvements when GPT-4V utilized in-context examples, emphasizing the model's potential to use contextual cues for enhancing interpretation accuracy.

Conclusion

The investigation illuminated GPT-4V's strengths and areas of improvement in relation to distribution shifts across a myriad of scenarios. Despite exhibiting promising adaptability and reasoning capabilities, the model did show inconsistencies in certain high-stakes domains, meriting ongoing refinement. Additionally, the study provided valuable insights into the role of in-context learning in assisting models with domain shifts, hinting at the promise of advanced learning techniques for the evolution of AI systems.
