+# PubMed Multi-label Text Classification Dataset
+
+This dataset consists of approximately 50,000 research articles sourced from the PubMed repository. The documents in this collection have been manually annotated by Biomedical Experts with their MeSH (Medical Subject Headings) labels. Each article is described in terms of 10-15 MeSH labels.
+
+## Dataset Details
+
+- **Original Annotation:** Biomedical Experts manually annotated the documents with MeSH labels.
+- **Label Space:** The original dataset had a large number of MeSH labels, resulting in an extensive output space and severe label sparsity issues.
+- **MeSH Major Labels:** Each article is annotated with MeSH major labels, reducing the label space and addressing label sparsity.
+
+## Data Processing and Label Mapping
+
+To overcome the challenges of an extremely large output space and severe label sparsity, the dataset has undergone processing and mapping to its root labels. The following steps were taken:
+
+1. **Label Reduction:** The original MeSH labels were reduced to their major categories.
+2. **Root Mapping:** The major labels were mapped to their corresponding root categories to simplify the output space.
+
+## Label Hierarchy
+
+The MeSH major labels in the dataset have been organized in a hierarchical structure, allowing for a more structured and interpretable representation of the biomedical concepts.
+
+## Data Statistics
+
+- **Number of Articles:** 50,000
+- **MeSH Labels:** Originally 10-15 per article, reduced to major labels.
+- **Root Labels:** Reduced and mapped categories for more manageable classification.
+
+
+## Acknowledgments
+
+I extend my gratitude to the Kaggle and Biomedical Experts who manually annotated the documents and contributed this dataset to Kaggle.

+# PubMed Multi-label Text Classification Project Overview
+
+## Overview
+
+This project focuses on multi-label text classification of biomedical research articles sourced from the PubMed repository. The dataset consists of approximately 50,000 documents, each manually annotated with MeSH (Medical Subject Headings) labels by Biomedical Experts. The primary challenge addressed in this project is the extensive output space and severe label sparsity issues in the original dataset.
+
+## Key Features
+
+- **Dataset:** 50,000 research articles from PubMed, annotated with MeSH labels.
+- **Label Reduction:** Original MeSH labels reduced to major categories.
+- **Root Mapping:** Major labels mapped to corresponding root categories for a simplified output space.
+- **Models:** Utilized BioBERT, RoBERTa, and XLNet for multi-label text classification.
+- **Results:** BioBERT demonstrated the highest accuracy at 87%, outperforming RoBERTa and XLNet.
+
+## Dataset Processing
+
+The dataset underwent preprocessing to address label sparsity and reduce the output space. Major MeSH labels were retained, and a hierarchical structure was introduced through root mapping for better interpretability.
+
+## Model Training
+
+- Three state-of-the-art pre-trained language models were employed: BioBERT, RoBERTa, and XLNet.
+- Training involved optimization for multi-label classification with a focus on improving F1 and flat validation accuracies.
+- Graphs depicting training loss, F1 validation accuracy, and flat validation accuracy over epochs are available in the `results` directory.
+- the training runs charts can be seen in weughts and Biases Dashboard:  https://wandb.ai/ai-guru/Multi%20Label%20Classification%20of%20PubMed%20Articles%20%28Paper%20Night%20Presentation%29
+
+## Conclusion
+
+BioBERT emerged as the most effective model, achieving an accuracy of 87%. The dataset analysis revealed Class B as the category with the highest number of articles. Training graphs illustrate the models' learning processes and performance improvements over epochs.
