Projects

RAGPal: A PoC RAG-based virtual assistant

RAGPal is implemented as a web application with a front-end interface for user interaction and a FastAPI-based back-end for handling requests and business logic. The system utilizes Azure OpenAI API resources for chat completion and embedding generation, and the Qdrant vector database to serve as the knowledge base for storing and retrieving documents.

End-to-End Chess Recognition

The goal of this project was to develop a methodology that would predict the chessboard configuration in an input image of a chessboard. Contrary to the predominant approaches, that aim to solve this task through the pipeline of chessboard detection, square localization, and piece classification, we relied on the power of deep learning models to directly predict the configuration from the entire image.

Chess Recognition Dataset (ChessReD)

The Chess Recognition Dataset (ChessReD) is a comprehensive collection of images of chess formations that were captured using various smartphone cameras. It comprises 10,800 images from 100 chess games. The dataset features a wide range of chess piece configurations, captured under different angles and lighting conditions. The dataset includes detailed annotations about the pieces' formations in chess algebraic notation, providing valuable information for chess recognition research. View more..

TeleGAN: Text-To-Image Synthesis using GANs

The goal of this project was to develop a novel architecture which would be able to generate high-resolution images conditioned on a given text description. The proposed model (TeleGAN) decomposes the difficult task of high-quality image generation, into the more manageable sub-problems of low-res black-and-white image generation, colorization, and resolution enhancement, in three consecutive stages.
