RiskBERT is a significant step forward, making it easier than ever to incorporate text fragments into various applications, such as insurance frequency and severity models, or other GLM-based models. Feel free to explore and utilize RiskBERT for your text analysis needs.

Example: pip install RiskBERT

from transformers import AutoTokenizer
import torch
from RiskBERT import glmModel, RiskBertModel
from RiskBERT import trainer, evaluate_model
from RiskBERT.simulation.data_functions import Data
from RiskBERT.utils import DataConstructor

# Set device to gpu if available
device = torch.device("cuda:0" if torch.cuda.is_available() else "cpu")

# Init the model
model_dataset = Data(20000, scores=torch.tensor([[0.2],[0.4]]), weigth=5)
pre_model= "distilbert-base-uncased"
model = RiskBertModel(model=pre_model, input_dim=2, dropout=0.4, freeze_bert=True, mode="CLS")
tokenizer = AutoTokenizer.from_pretrained(pre_model)
# Train the model
model, Total_Loss, Validation_Loss, Test_Loss = trainer(model =model, 
        model_dataset=model_dataset, 
        epochs=100,
        batch_size=1000,
        evaluate_fkt=evaluate_model,
        tokenizer=tokenizer, 
        optimizer=torch.optim.SGD(model.parameters(), lr=0.001),
        device = device
        )

# Predict from the model
my_data = DataConstructor(
    sentences=[["Dies ist ein Test"],["Hallo Welt", "RiskBERT ist das Beste"]], 
    covariates=[[1,5],[2,6]],
    tokenizer= tokenizer).prepare_for_model()
my_prediction=model(**my_data)
