ViLaH

ViLaH

ViLaH (Vision Language Hindi) is a model with 3 billion parameters, fine-tuned from the base-model google/paligemma-3b-pt-224 to handle input images and bilingual (Hindi and English) text sequences for both input and output.

Training Details

• Model Configuration: Fine-tuned on a single epoch using a V100 gpu.
• Training Duration: Approximately one day.
• Evaluation Loss: Achieved an eval loss of 1.6384 at the end of the epoch.
• The model is still being train as of right now with better quality dataset
• The model's performance may be compromised due to insufficient data and the fact that it was trained for only one epoch.

Dataset

The model was finetuned on only one dataset

• damerajee/clean_hin_vqa : This dataset was derived from Lin-Chen/ShareGPT4V and filtered to include only images from the COCO dataset. The original dataset was translated and cleaned to ensure high-quality Hindi visual question answering content.

How to Use
