Current Project:

Toxic Comment Detection:

A project in Kaggle to detect the toxic comments made on social media. It is an NLP problem that classifies the level of toxicity in six different states as toxic, severe toxic, obscene, threat, insult, and identity hate. The main challenges are to clean the text, and to equate the classes in training data.

Software Published:

“Torrit” – Published the beta version of a power system simulation tool in October, 2017. It is developed with Python tkinter, numpy, jsonpickle etc. It can be downloaded from, https://goo.gl/FKcmrW

Projects:

Grocery Demand Prediction:

Participated in a competition in Kaggle to predict the demand of more than 4000 items for 50 different stores. The data were given for around 3 years with different factors that may affect the decisions like price of oil, holidays events etc. The training set contained around 4.8 GB of data that makes the problem a real challenge. I have used Palmetto cluster from Clemson University to run the kernel.

Elman Recurrent Neural Network Based State Prediction

Elman Recurrent Neural Network (ERNN) is a special type of neural network for predicting time-series signals. Due to the feed-back of the hidden layer outputs as the context layer, it requires a special training method called Back-Propagation Through Time (BPTT). In this project, the network is trained to predict the states of a power system. Through rigorous training, the mean absolute percentage error is taken below 1% for system angles. This project is funded by National Science Foundation.

Parallel processing of Constant Jacobian Method

The process of Weighted Least Squares (WLS) takes a long time specially for high dimensional problems like state estimation. In this project, the linear version of the WLS estimator named as constant Jacobian method is parallelized on an NVIDIA GPU (CUDA). To the best of the researchers’ knowledge, this is the fastest estimator ever presented in the literature. This is funded by Department of Enenrgy.

Particle Filter Using CUDA-MPI:

Particle filter is a particle based heuristic algorithm which is very suitable for parallel implementation. In this project, a particle filter algorithm was developed to estimate the states of a power system using CUDA and MPI.

Optical Character Recognition:

In this project, a complete OCR is developed from scratch. It reads from the image of a table, and writes the table in an excel file. It includes the option for designing the characters. The designed characters are compared with the detected characters from the table. The accuracy was around 90%.
