Creation of PDF Chatbots: Worked on the creation of PDF Chatbots using Langchain Framework with the utilization of RAG Based Architecture. Used Unstructured API for efficient text structuring and embedding generation and Claude AI LLM to form a PDF Question Answering System. Concept Extraction: Worked on querying various Open Source Knowledge Graphs for searching linked terms to a given concept which was utilized in better search procedures relating to the term.

Entity Aspect Linking: Worked on design of an efficient algorithm using link prediction to correctly link the possible aspects of a content to the entities mentioned in a given context with the utilization of various Graph Neural Networks Architectures with Fine Tuned BERT Text Embeddings as Features.

Landslide Mortality Modelling through Geographically Weighted Regression(GWR): Worked on Spatial modelling of the effects of meteorological, topological and soil related factors on Landslide Mortality. Comparison was done on Normal GWR, Poisson GWR and Multiscale GWR. Modelling of PM2.5 through Geographically Weighted Regression(GWR): Worked on Spatio-Seasonal modelling of the effects of meteorological, socio-demographic and pollutant factors on PM2.5 levels on a seasonal basis.

Knowledge Graph Reconstruction Analysis: Worked on the creation of Knowledge Graph Embeddings from benchmark Knowledge Graph datasets through various embedding methods such as HOPE, SDNE, LINE, Node2Vec followed by Graph Reconstruction to analyse the performance of the embedding techniques. Knowledge Graph Merging with Autoencoders: Worked on merging of Knowledge Graphs using Autoencoders to generate subgraph embeddings and intermediate meta embeddings followed by Knowledge Graph reconstruction for analysis of Meta embedding generation techniques.
