These Models pre-trained on over 500GB of Persian data including a variety of topics such as News, Blogs, Forums, Books, etc. They pre-trained with the MLM (WWM) objective using two context lengths.18 19For more information you can read our paper on [arXiv](https://arxiv.org/abs/2407.16382).20 21## How to use22 23You can use this model directly for Masked Language Modeling using the provided code below.24 25```Python26from transformers import AutoTokenizer, AutoModelForMaskedLM27 28tokenizer = AutoTokenizer.from_pretrained("PartAI/TookaBERT-Base")29model = AutoModelForMaskedLM.from_pretrained("PartAI/TookaBERT-Base")30 31# prepare input32text = "شهر برلین در کشور <mask> واقع شده است."33encoded_input = tokenizer(text, return_tensors='pt')34 35# forward pass36output = model(**encoded_input)37```38 39It is also possible to use inference pipelines such as below.40 41```Python42from transformers import pipeline43 44inference_pipeline = pipeline('fill-mask', model="PartAI/TookaBERT-Base")45inference_pipeline("شهر برلین در کشور <mask> واقع شده است.")46```47 48You can use this model to fine-tune it over your dataset and prepare it for your task.49 50- DeepSentiPers (Sentiment Analysis) <a href="https://colab.research.google.com/drive/1Vn5QTYutdCo6iXVTmsPW9K4t8xVk14ji#scrollTo=1B1YrypZxajF"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Colab Code" width="87" height="15"/></a>51- ParsiNLU -
