In the rapidly evolving field of artificial intelligence, image classification models have become essential tools for various applications, including computer vision in art analysis. In this blog, we’ll explore two specific models, comparing their performances through systematic metrics such as FLOPS, parameters, accuracy, and AUC (Area Under Curve). By the end, you’ll have a clearer understanding of how these metrics work and what they indicate about model performance.

Models Overview

Let’s dive into the details of the two image classification models and their respective performance metrics:

Name                     FLOPS      Params     Accuracy    AUC
caformer_s36_v0         22.10G     37.22M     71.03%      0.9271
mobilenetv3_v0_dist     0.63G      4.18M      65.74%      0.9053

Performance Metrics Explained

To better understand these models and their respective performances, let’s break down the key metrics:

• FLOPS: This stands for Floating Point Operations Per Second, and it gives us an idea of the computational resources required by the model. Higher FLOPS typically indicate more complex models.
• Parameters: The number of trainable parameters in a model. More parameters can lead to a more expressive model but can also result in overfitting.
• Accuracy: This is a direct measure of how often the model makes correct predictions. A higher accuracy means better performance in real-world applications.
• AUC: The Area Under Curve metric provides insight into the model’s ability to distinguish between classes. A value closer to 1 means better performance.

Comparative Analysis

Now, let’s compare the two models:

• Caformer_s36_v0: With 22.10G FLOPS and 37.22M parameters, it achieves an accuracy of 71.03% and an AUC of 0.9271. This model is quite powerful due to its high computational requirements, making it suitable for intricate tasks.
• MobileNetV3_v0_dist: This model, on the other hand, is significantly less complex with only 0.63G FLOPS and 4.18M parameters. Its accuracy is lower at 65.74%, but it still maintains a respectable AUC of 0.9053, indicating it can reliably differentiate between classes, albeit with slightly less precision.

Visual Representation of Confusion

Troubleshooting

If you’re looking to implement or troubleshoot these models, consider the following suggestions:

• Ensure that you have the right computational resources according to the FLOPS requirement of your chosen model.
• If your model is underperforming, consider tuning the parameters or using a different optimizer.
• Always visualize the confusion matrix to understand where your model is making errors. It can give insights into categories that may need more training data.
