MobileCLIP2: Slimming Down CLIP for Your Phone

This paper introduces MobileCLIP2, a family of smaller and faster image-text models based on CLIP, optimized for mobile devices. By improving the training data and process, MobileCLIP2 achieves state-of-the-art zero-shot image classification accuracy on ImageNet-1k while being significantly smaller and faster than comparable models. Notably, some variants trade off a small amount of retrieval performance for improved classification accuracy.

Possible Conflicts of Interest

All authors are affiliated with Apple, which could indicate a potential conflict of interest regarding prioritizing mobile deployment.

Identified Weaknesses

Lack of comprehensive architectural analysis

The authors introduce new architectures and training improvements but lack detailed comparisons or ablation studies on architectural choices.

Limited scope of evaluation tasks

Limited evaluation on broader vision tasks.

Trade-off in retrieval performance for zero-shot classification

The focus is primarily on zero-shot classification, and retrieval performance is sometimes compromised, potentially limiting its application in other areas.

Rating Explanation

The paper presents a valuable contribution by optimizing a foundational model like CLIP for mobile devices. The new training methods and architectures improve efficiency without significant performance loss, which is significant for real-world applications. However, the limited evaluation scope and lack of complete ablations prevent a perfect score.
