Machine learning and Reinforcement Learning projects (Python)
Supervised learning – Used large two public datasets to do model complexity analysis and
learning curve analysis to do comparison between different supervised learning algorithms
Decision Tree, Neural network, Boosting, KNN, SVM
Randomized optimization – estimated the weights of neural network used for public dataset
using randomized optimization algorithms Random hill climbing, Simulated annealing, Genetic
algorithm and Mimic and also implemented these algorithm’s to implement model comparison
for 2 NP hard problems – Knapsack and One max.
Unsupervised learning and dimensionality reduction – used clustering (Kmeans and Estimation
Maximization) methods to do model selection on two large public datasets and also performed
dimensionality reduction using PCA, ICA, Random projections and Ida and analyzed
the results of applying clustering on reduced datasets. Applied the clustering algorithms to
the same datasets treating the clusters as if they were new features and ran neural network
learner on the newly projected data and analyzed the results.
Implemented Markov Decision process for Frozen Lake problem and Taxi v2 problem using
open Gym AI and compared performance using value iteration as well as policy iteration for
smaller size and larger size of the problem respectively and also solved the same problems
using model free Q learning algorithm.
Replicated the results in Sutton’s paper (Learning to predict by Temporal difference methods)
random walk experiment
Implemented Lunar Lander experiment using Open Gym AI package and proved convergence
using Deep Q Learning algorithm. Trained the Lunar lander agent to achieve an average score
of 200 over 100 consecutive episodes. Performed series of experiments using difference
range for model hyper parameters and observed the impact on the agent convergence.
Replicated the results in RoboCup experiment described in Correlated Q-Learning by Amy
Greenwald and Keith Hall paper using difference variants of correlated Q learning , Friend Q
and Foe Q learning approaches.
Artificial Intelligence (Python) projects
Implemented Game playing agent using minimax, alpha beta, iterative deepening and alpha
beta pruning approaches respectively. The goal was to win against random player 100% of
the time and trained player using minimax and alpha beta 70% of the time and iterative
deepening and alpha beta trained agent 60% of the time.
Implemented various search algorithm (breath first search, uniform cost search, a-star, bidirectional
UCS, bidirectional a-star and tri-directional search methods) for a graph and performed
the performance analysis.
Implemented Bayes net, decision tree, expectation maximization, hidden markov model
model from scratch using python.
Data Science projects executed (R Programming)
Implemented data analysis for large movie dataset and implemented preprocessing (Data
standardization, binning, label encoding etc) using R and performed data visualizations on
feature’s to identify dependencies and patterns or trends.
Performed linear regression and logistics regression on movie dataset and estimated the performance
of each algorithm
Implemented time series and Geospatial data visualization’s in R.
Big Data projects(Scala, Hadoop, Hive, PIG, HBase, Spark, Pytorch)
Implemented multiple projects for Health Care for large dataset performing predictive modeling
utilizing Scala, Hadoop (Map reduce), PIG (ETL), Spark (ETL processing) and Spark
graphx and MLib modules
Chest X Ray diagnosis utilizing Deep Convolution neural network by using transfer learning
from DenseNet 121 layer pytorch CNN model. The model was trained using NIH Chest X Ray
dataset which contains 110K images from approx 38K patients. Overall RUC AOC of 0.8 was
achieved in this research.
Android development (Java)
Developed a Encryptor utility app to produce a cipher text based on message, key number
and increment number as input. The core encryption logic was developed in java.
Implemented a word game (simplified form of scrabble) for Android OS following Agile software
development methodology using Java. Created game manual, project plan, test plan,
design document, use case model, component diagram, deployment diagram, UML design,
low level design as part of project documentation.
