Portfólio

This paper presents a novel approach for predicting the path of active particles using time series analysis, LSTM networks, and Transformers. The proposed method outperforms other approaches' accuracy and robustness, especially in complex scenarios with particle interactions and noise.

Brownian Motion of A-Particles Using Pre-LN Transformers

Engineered a library that can automatically detect driving patterns while driving and set the battery parameters to the required states accordingly; to save the battery for longer life using IIoT, Neural Nets, and Statistics. Re-Trained TV4DX-LSTM, based on real-time data from SoC and PI, by 6.4%

PyBMS:BMS using Sync-LSTM with Parallel Rectified Filtration

Multi-Purpose Rank Estimating Recommendation Engine Using Blend of RankNet and LambdaMart with Normalized Discounted Cumulative Gain (NDCG) The pipeline developed a machine learning algorithm to rank the top 93 companies based on customer base, outreach, and social media presence. RankNet and LambdaMart were used for ranking, and NDCG/MAP was used to assess model performance. K-Nearest Neighbors was used for feature engineering.

Rank Estimating Recommendation with RankNet & LambdaMart

SaaS companies are customer-driven and are heavily dependent on their customer base. There are a set of metrics that can showcase the health of the SaaS companies and their aspects. These metrics and numbers are not readily available on publicly reported SEC Filings and need to be chalked out.

SEC Filling Analyzer for SaaS Companies using EDGAR Data

Causality detection draws plenty of attention in the field of Natural Language Processing and linguistics research. It has essential applications in information retrieval, event prediction, question answering, financial analysis, and market research. In this study, we explore several methods to identify and extract cause-effect pairs in financial documents using transformers. For this purpose, we propose an approach that combines POS tagging with the BIO scheme, which can be integrated with modern transformer models address this the challenge of identifying causality in a given text.

Combining POS-tag with Context Embed for Causality Detection

An efficient and robust communication channel is a critical factor in underground coal mines to ensure the safety of the working environment. Applying predictive machine learning of convergence, load at withdrawal and duration of yielding in hrs will automate the analysis of the after-effects of depillaring operations. Trained GLEs and GBEs ensembled using XGBoost and Random Forests Regressor on CTGANs sampled data to predict timed Convergence/Withdrawal Load on Rise/Dip side and achieved R2 score 0.91, 0.89 respectively. Developed an advanced technique to extract the ’yielding time’.
