Model description

This model is a fine-tuned version of google/vit-base-patch16-224-in21k on the Lokier & Al Junaibi (2016) data S1.

The model captures the expertise of 177 volunteers from 33 countries with 3,270 years of academic & industry experience in classifying 14 carbonate thin section samples by using the classical Dunham (1962) carbonate classification.

(Source)

In the original paper, the authors intended to objectively analyze whether these volunteers have the same standards in applying Dunham classification.

Intended uses & limitations

• —Input: Carbonate thin section image, can be either parallel-polarized (PPL) or cross-polarized (XPL)
• —Output: Dunham classification (Mudstone/Wackestone/Packstone/Grainstone/Boundstone/Crystalline) and the probability value
• —Limitation: The original dataset is missing Boundstone sample, hence it cannot classify a Boundstone.

Sample image source: Grainstone - Wikipedia

Training and evaluation data

Source: Lokier & Al Junaibi (2016), Data S1

The data consists of 14 samples. Each samples has 3 magnifications (x2, x4, and x10) and taken in PPL and XPL. Hence, there are 14 samples 3 magnifications 2 polarizations = 84 images in the training dataset.

Classification for each sample is taken from the most popular respondent's response in Table 7.

• —Sample 1: Packstone
• —Sample 2: Grainstone
• —Sample 3: Wackestone
• —Sample 4: Packstone
• —Sample 5: Wackestone
• —Sample 6: Packstone
• —Sample 7: Packstone
• —Sample 8: Mudstone
• —Sample 9: Crystalline
• —Sample 10: Grainstone
• —Sample 11: Wackestone
• —Sample 12: Grainstone
• —Sample 13: Grainstone
• —Sample 14: Mudstone
