ComfyUI-Classifier

ComfyUI-Classifier is a custom node for ComfyUI that uses a zero-shot classification model to classify text inputs based on a set of candidate labels. This node leverages the power of Hugging Face Transformers to provide accurate and flexible text classification.

Features

Text Classification: Classify text inputs using zero-shot classification.
Customizable Labels: Provide your own set of candidate labels for classification.
Flexible Output: Choose between JSON or plain text output formats.
Score Inclusion: Option to include classification scores in the output.

Installation

Clone the Repository: Clone this repository into your custom_nodes folder in ComfyUI.

git clone https://github.com/fexploit/ComfyUI-Classifier custom_nodes/ComfyUI-Classifier

Install Dependencies: Navigate to the cloned folder and install the required dependencies.
```
cd custom_nodes/ComfyUI-Classifier
pip install -r requirements.txt
```

Usage

Adding the Node

Start ComfyUI.
Add the ClassifierNode from the custom nodes list.
Connect a text input and configure the parameters as needed.

Parameters

text_input (required): The input text to be classified.
candidate_labels_json (required): A JSON string containing the candidate labels and their initial scores.
num_labels (optional): Number of labels to select (default: 10).
include_scores (optional): Boolean flag to include scores in the output (default: True).
output_format (optional): The output format, can be "json" or "text" (default: "json").

Example

# Example usage in a script
text_input = "Dune is the best movie ever."
candidate_labels_json = '''
[
  {"tag": "CINEMA", "score": 0.9},
  {"tag": "ART", "score": 0.1},
  {"tag": "MUSIC", "score": 0.05}
]
'''

classifier_node = ClassifierNode()
output = classifier_node.classify(text_input, candidate_labels_json, num_labels=3, include_scores=True, output_format="json")
print(output)
