Fake Vs. Real News Classification

https://www.kaggle.com/surbhig/classification-fake-vs-news-95-accuracy
I created and published a Kaggle notebook to classify a given news paragraph into fake vs. real, with 95% accuracy. Kaggle dataset for fake vs. real news was used for training and testing. I used the multinomial Naive Bayes for classification and TF-IDF for feature vectorization.

Optimization Using Meta-heuristics

https://github.com/droid-surbhi/Optimization
I developed and published a GitHub repository for optimization using popular metaheuristics like tabu search and artificial bee colony optimization (ABC). Tabu search was written from scratch in MATLAB, while ABC was written in Python and is a modified version of the code published by the original author of the algorithm. The modifications were made to enable constrained integer optimization using ABC.

Design Optimization of Minimally Invasive Surgical Robot

https://doi.org/10.1016/j.asoc.2015.03.032
We optimized the design within three degrees of freedom serial robotic arm to operate as a minimally invasive robotic surgery (MIRS) arm and attain multiple adjacent possible orifice locations, through which a planar workspace of prespecified geometry can be traced. To achieve this goal, we developed an algorithm to relate the design of such a MIRS arm to the possible orifice positions. The optimization problem was solved using several metaheuristics such as simulated annealing, Tabu search, artificial bee colonization, and genetic algorithm, and their performance was compared.

LighVe: Music Synced Lights

LighVe is a set composed of light strips and a mobile app. LighVe can pick up any music that is being played in the room and synchronize the light visualizations with its beats. I worked on the hardware, circuit design, electronics, and app design while another collaborator developed the backend.

Kinematic Control of An Articulated Minimally Invasive Surgical Robotic Arm

https://ieeexplore.ieee.org/document/7853054
We created geometric transformations based on the constraints acting on the end-link coupled with kinematic-relations obtained using conventional techniques were used to drive a simulated 6-DOF general articulated robotic arm for minimally-invasive operations. This simulated arm verified the method by tracing predefined planar and 3D trajectories.

Clustering Utilities
