Image Classification Using CAFormer and MobileNet Models: A Guide

Feb 16, 2024 | Educational

In the ever-evolving landscape of image classification, many models have been developed to enhance performance and accuracy. Here, we will dive into the specifications and metrics of several CAFormer and MobileNet models, and help you understand how to utilize them effectively.

Understanding the Metrics

Before we delve into the models, let’s clarify some crucial metrics used to assess their performance:

  • FLOPS: This stands for Floating Point Operations per Second, a measure of model complexity.
  • Params: The number of parameters in the model, indicating its size and learning capacity.
  • Accuracy: The percentage of correct predictions made by the model.
  • AUC: Area Under the Curve, representing the model’s ability to distinguish between the classes.

CAFormer Model Overview

The CAFormer models exhibit impressive performance metrics as described in the following table:


  Name                     FLOPS    Params    Accuracy    AUC
  caformer_s36_v0          22.10G   37.21M    96.46%      0.9931
  caformer_s36_v0_c_sce    22.10G   37.21M    95.69%      0.988
  caformer_s36_v1          22.10G   37.22M    93.95%      0.9787
  caformer_s36_v2-beta     22.10G   37.22M    96.40%      0.9915
  caformer_s36_v2.1        22.10G   37.22M    93.82%      0.989
  caformer_s36_v2.2        22.10G   37.22M    93.80%      0.9886
  caformer_s36_v2          22.10G   37.22M    93.42%      0.9801

Analogy: The CAFormer as a Fine Art Gallery

Think of the CAFormer models as different exhibition rooms in a prestigious art gallery. Each room holds a collection of artwork that attracts different audiences:

  • Exhibition Room (Model Name): Each room has its unique theme — just like model versions (e.g., caformer_s36_v0).
  • Artwork Complexity (FLOPS): The more intricate artworks require more attention and contemplation, similar to higher FLOPS meaning more computational heft.
  • Visitor Feedback (Accuracy): Just as guests provide feedback through ratings, the accuracy value tells us how well the model performs.
  • Gallery Reputation (AUC): This reflects the overall quality of the gallery, with higher AUC values demonstrating the model’s ability in distinguishing classes.

MobileNet Model Overview

The MobileNet models are smaller but still highly effective. Below are their metrics:


  Name                      FLOPS    Params    Accuracy    AUC
  mobilenetv3_v2.1_dist     0.63G    4.18M     92.89%      0.9864
  mobilenetv3_v2.2_dist     0.63G    4.18M     93.28%      0.9864
  mobilenetv3_v2_dist       0.63G    4.18M     92.27%      0.9762

Analogy: The MobileNet as a Compact Bookstore

Imagine MobileNet models as compact yet efficient bookstores, where each shelf holds a curated list of bestsellers and classic literature:

  • Bookshelves (Model Name): Different sections of the bookstore (e.g., mobilenetv3_v2.1_dist) cater to various reader preferences.
  • Page Count (FLOPS): A smaller book with concise content can still convey powerful stories, analogous to lower FLOPS but effective performance.
  • Reader Ratings (Accuracy): Higher ratings reflect how entertaining or informative the book is, akin to model accuracy.
  • Overall Sales (AUC): As successful books demonstrate their appeal across genres, higher AUC values signify excellent performance in distinguishing outcomes.

Troubleshooting Tips

While using these models, you might encounter certain issues. Here are some troubleshooting tips to guide you:

  • If the model fails to train or perform as expected, check the data input format and ensure it aligns with the model requirements.
  • In case of slow performance, consider using smaller batch sizes or optimizing your hardware setup.
  • For any confusion regarding model versions, refer to the respective documentation or community forums for clarification.
