# FoodExtract-v2
|
||||
|
||||
This is a food and drink extraction language model built on [Gemma 3 270M](https://huggingface.co/google/gemma-3-270m-it).
|
||||
|
||||
Given raw text, it's designed to:
|
||||
|
||||
1. Classify the text into food or drink (e.g. "a photo of a dog" = not food or drink, "a photo of a pizza" = food or drink).
|
||||
2. Tag the text with one or more tags (see tags_dict below).
|
||||
3. Extract the edible food-related items as a list.
|
||||
4. Extract the edible drink-related items as a list.
|
||||
|
||||
For example, the input text might be:
|
||||
|
||||
```
|
||||
British Breakfast with baked beans, fried eggs, black pudding, sausages, bacon, mushrooms, a cup of tea and toast and fried tomatoes
|
||||
```
|
||||
|
||||
And the model will generate:
|
||||
|
||||
```
|
||||
food_or_drink: 1
|
||||
tags: fi, di
|
||||
foods: British Breakfast, baked beans, fried eggs, black pudding, sausages, bacon, mushrooms, toast, fried tomatoes
|
||||
drinks: tea
|
||||
```
|
||||
|
||||
This model can be used for filtering a large image caption (e.g. [DataComp-1B](https://huggingface.co/datasets/UCSC-VLAA/Recap-DataComp-1B)) text dataset for food and drink related items.
|
||||
|
||||
## Dataset
|
||||
|
||||
The model was trained on the [FoodExtract-135k](https://huggingface.co/datasets/mrdbourke/FoodExtract-135k) dataset.
|
||||
|
||||
This dataset contains 135,000 samples of raw text and JSON output pairs of structured food extractions provided by `gpt-oss-120b`.
|
||||
|
||||
For example, a raw image caption input might be:
|
||||
|
||||
```
|
||||
another optional quest takes place on windfall island during the night time play the song of passing a number of times and each time, glance towards the sky
|
||||
```
|
||||
|
||||
And the `gpt-oss-120b` generated output (JSON) would be:
|
||||
|
||||
```
|
||||
{'is_food_or_drink': 'false', 'tags': [], 'food_items': [], 'drink_items': []}
|
||||
```
|
||||
|
||||
This is condensed to:
|
||||
|
||||
```
|
||||
food_or_drink: 0\ntags: \nfoods: \ndrinks:
|
||||
```
|
||||
|
||||
### Tags dictionary mapping
|
||||
|
||||
These tags are designed for fast filtering.
|
||||
|
||||
For example, the model can assign a certain tag based on what's in the raw text and then we can filter for "ingredient list" items.
|
||||
|
||||
```
|
||||
tags_dict = {'np': 'nutrition_panel',
|
||||
'il': 'ingredient list',
|
||||
'me': 'menu',
|
||||
're': 'recipe',
|
||||
'fi': 'food_items',
|
||||
'di': 'drink_items',
|
||||
'fa': 'food_advertistment',
|
||||
'fp': 'food_packaging'}
|
||||
```
|
||||
|
||||
## Helper functions
|
||||
|
||||
The model is trained to output a condensed version of the structured data.
|
||||
|
||||
We do this so the model can generate less tokens (e.g. it doesn't have to generate JSON outputs).
|
||||
|
||||
The following functions help to condense and uncondense raw text outputs/inputs into the desired structure.
|
||||
|
||||
```python
|
||||
def condense_output(original_output):
|
||||
'''Helper function to condense a given FoodExtract string.
|
||||
|
||||

|
||||
|
||||

|

return condensed_output_string_formatted.strip()

## Quick start
|
||||
|
||||
```python
|
||||
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
|
||||
|
||||
MODEL_PATH = "mrdbourke/FoodExtract-gemma-3-270m-fine-tune-v2"
|
||||
|
||||
# Load the model into a pipeline
|
||||
loaded_model = AutoModelForCausalLM.from_pretrained(
|
||||
pretrained_model_name_or_path=MODEL_PATH,
|
||||
dtype="auto",
|
||||
device_map="auto",
|
||||
attn_implementation="eager"
|
||||
)
|
||||
|
||||
# Load the tokenizer
|
||||
tokenizer = AutoTokenizer.from_pretrained(
|
||||
pretrained_model_name_or_path=MODEL_PATH,
|
||||
)
|
||||
|
||||
# Create model pipeline
|
||||
loaded_model_pipeline = pipeline("text-generation",
|
||||
model=loaded_model,
|
||||
tokenizer=tokenizer)
|
||||
|
||||
# Create a sample to predict on
|
||||
input_text = "A plate with bacon, eggs and toast on it"
|
||||
input_text_user = [{'content': input_text, 'role': 'user'}]
|
||||
|
||||
# Apply the chat template
|
||||
input_prompt = loaded_model_pipeline.tokenizer.apply_chat_template(conversation=input_text_user,
|
||||
tokenize=False,
|
||||
add_generation_prompt=True)
|
||||
|
||||
# Let's run the default model on our input
|
||||
default_outputs = loaded_model_pipeline(text_inputs=input_prompt,
|
||||
max_new_tokens=256)
|
||||
|
||||
# View the outputs
|
||||
print(f"[INFO] Test sample input:\n{input_prompt}\n")
|
||||
print(f"[INFO] Fine-tuned model output:\n{default_outputs[0]['generated_text'][len(input_prompt):]}\n")
|
||||
```
|
||||
|
||||
You should see an output similar to:
|
||||
|
||||
```
|
||||

|

```
|
||||
|
||||
## Training procedure
|
||||
|
||||
This model was trained with SFT (Supervised Fine-Tuning) via Hugging Face's TRL library.
