isl-img2text

Author: Sigurdur Haukur Birgisson

This model is a fine-tuned version of microsoft/git-base on Sigurdur/isl-image-captioning. It achieves the following results on the evaluation set:

• eval_loss: 0.0983
• eval_wer_score: 0.7295
• eval_runtime: 20.5346
• eval_samples_per_second: 7.792
• eval_steps_per_second: 0.974
• epoch: 15.0
• step: 150

It appears that the model heavilly overfitted to the dataset. Also, something I failed to consider was that the base model can't write any Icelandic characters and was thus not suited for this task. Future works might want to add the capability of writing Icelandic characters to the model.
