- Flask
- CSS
- PostgreSQL
03
PicFusion
PicFusion is a photo-based social media platform with the ability of meta-data searching and user interactions. The platform will enable users to upload, view, and interact with photos.
It leveraged Amazon S3 for photo storage, utilized AWS RDS for data management and scalability, and utilized external Geocoding API for location services.
- Node.js
- Python
- AWS S3
- AWS RDS
04
Multi Label Classification on Movie Genres
Designed a system capable of identifying movie genres based on their plot overview.
Fine-tuned a pre-trained transformer-based model, RoBERTa, whose Micro ROC-AUC score is 0.932, which outperforms the baseline model, Logistic Regression classifier with TF-IDF vectorizer, whose score is 0.910.
- Jupyter Notebook
- Pytorch
- RoBERTa
