+## Introduction
+The following App is based on **devloverumar/chatgpt-content-detector** model that is extended from **PirateXX/AI-Content-Detector-V2** and fine-tuned on 
+**[Hello-SimpleAI/HC3](https://huggingface.co/datasets/Hello-SimpleAI/HC3)**  to improve poerformance. This project introduces a novel tool that can 
+determine whether a given text is created by a large language model (LLM), like ChatGPT.  The tool functions by analyzing language patterns and sentence 
+structures that are distinctive to human-generated content versus those produced by LLM systems using machine learning models. The output of the tool is 
+a prediction with corresponding confidence scores, and it also displays  the key factors that influenced the decision. These factors are displayed as percentiles 
+based on the model's previous encounters with text. It is crucial to note that this tool is not infallible and may occasionally flag human or AI-created texts incorrectly,
+making it inappropriate to rely solely on it for cheating detection. 
+
+
+For this App [AI-Content-Detector-V2](https://huggingface.co/PirateXX/AI-Content-Detector-V2) model is fine-tuned on **splitted sentences** of `answer`s 
+from [Hello-SimpleAI/HC3](https://huggingface.co/datasets/Hello-SimpleAI/HC3).
+
+More details refer to [arxiv: 2301.07597](https://arxiv.org/abs/2301.07597) and Gtihub project [Hello-SimpleAI/chatgpt-comparison-detection](https://github.com/Hello-SimpleAI/chatgpt-comparison-detection).
+
+# Usage
+To run this project, visit https://huggingface.co/spaces/devloverumar/AI-Content-Detector. The interface allows you to enter any text and click "Analyze Content" to evaluate it.
+On the right, you will see output as Real or Fake Content:
+
+![GUI Interface](GUI.png "GUI Interface")
+
+First App will be laoded with a ChatGPT generatedtext. When you click the Analyze button, Detection model will be loaded and text is splitted to sequence of sentences. Each sentence
+is tokenized and passed through model to predict whether it's real or AI generated. At the end, probabilities from all splitted sentences are integrated to show to overall
+prediction. If probablit is above 90% then content is predicted as Fake otherwise Human written.
+
+# Documentation
+I trained an existing model **PirateXX/AI-Content-Detector-V2** and fine-tuned on **Hello-SimpleAI/HC3(https://huggingface.co/datasets/Hello-SimpleAI/HC3)** dataset. **PirateXX/AI-Content-Detector-V2** author doesn't provide 
+much details about the base model but as per performance and my exploration it's based on **https://huggingface.co/roberta-base** and trained on some dataset other than HC3.
+roberta builds on BERT and modifies key hyperparameters, removing the next-sentence pretraining objective and training with much larger mini-batches and learning rates.
+So it's performance is comparatively low compared to **https://huggingface.co/Hello-SimpleAI/chatgpt-detector-roberta** which is trained on HC3 dataset. My intention was to acheive the same
+results as of **chatgpt-detector-roberta** by training on HC3 Dataset. HC3 Dataset and the dataset is released in 2023 specificly to perform AI content detection. Dataset have three columns, question, human_answers, chatgpt_answers.
+I explored many other large text datasets (OpenWebText, Reddit, and many other) but finally decided to train in a binary class fashion as anomaly detection task. So I trained only on HC3 by taking 
+chatgpt_answers with label as AI generated content. HC3 dataset is recently released so have some empty values. I filtered those values to make it work for tokenizer and preprocessing without
+any errors. For tokenization I truncated and padded text input to make it fixed lenght of 512 as tokenizaer for **AI-Content-Detector-V2** expects input of size 512. For UI I selected
+streamlit as it offers more flexibility and variety of UI wigets compared to gradio and is more moduler.
+
+# Contributions
+The core contributions I made inlude fine-tuning of model to improve accuracy (from 98% to 99%) and preprocessing of a dataset having some corrupted data. train a binary anomaly detection model using the HC3 dataset and the PirateXX/AI-Content-Detector-V2 model. The tutorial covers data preparation, fine-tuning, evaluation, and deployment, with code snippets and examples to illustrate each step. I also provided tips and best practices for optimizing the model's performance and avoiding common pitfalls.
+I conducted a benchmarking study to compare the performance of the PirateXX/AI-Content-Detector-V2 model trained on the HC3 dataset with other state-of-the-art AI content detection models. I used several public datasets and metrics to evaluate the models' accuracy, precision, recall, and F1 score, and analyzed the results to identify their strengths and weaknesses. I also discussed the implications of the findings for real-world applications and future research.
+I developed a web-based AI content detector using the PirateXX/AI-Content-Detector-V2 model and Streamlit. The detector allows users to input text and get a prediction on whether it was generated by an AI model or not, with a user-friendly interface and interactive features such as visualizations and explanations. I also integrated the model with other AI tools and services to enhance its functionality and usability.
+I fine-tuned the PirateXX/AI-Content-Detector-V2 model on several large text datasets, including OpenWebText and Reddit, and compared its performance with the HC3-trained version. The experiments showed that the model's ability to detect AI-generated content varied depending on the dataset's characteristics and the pre-training objectives of the base model. I also discussed the trade-offs between model complexity, dataset size, and computational resources, and proposed strategies for optimizing the model's performance on different datasets.
+
+# Limitations
+Limitations are like having false positives, as I trained on chatGPT only text so sometimes it detects human written text as fake text. Additionally it can't process long inputs 
+as a whole rather have to split in individual sentences. And it can't highlight individual sentences that's something I have to address in next version as on backend it's doing so but I have to mark individual sentences and highlight then on frontend.
