Projects

• Sentiment Analysis

  • Designed a sentiment detection model for movie reviews using the sequential models.
  • Implemented an LSTM based model which outperformed vanilla RNN by 50% accuracy.

• Image Style Transfer

  • Tasked to transfer style from an art image to a content image. Implemented convolutional neural network model (VGG19) to extract the feature map.
  • Introduced an additional convolution layer and fine-tuned feature weights resulting in obtaining the visually optimal image.

• Database and Query Processing

  • Designed multidimensional cubes using SQL Server Data Tools and SQL Server Management Studio and performed OLAP using MDX on large volume of data from the data warehouse.
  • Worked with NoSQL database management system (Neo4j, MongoDB) and geospatial data using geographic system application (QGIS).

• Integration of Chameleon Cloud with LLVM Compilation

  • Provisioned a bare-metal node and launched a bare-metal instance.
  • Built a functional docker container from image, compiled a C program into intermediate representation (IR) code using LLVM/Clang, and deployed it in the cloud.
