Source to Source Translator using Rose Compiler
A source-to-source compiler translates between programming languages that operate at approximately the same level of abstraction. In this project, we have tried to develop a source-to-source compiler that automatically translates the given C program into another C program with instructions replaced for the target platform (Universal Multifunction Accelerator [UMA], developed by Manjeeera Digital Systems) that supports an extended instruction set. In order to accomplish this task we take help of Rose compiler, an open source compiler infrastructure to build source-to-source compilers.
Finding Convex Hull using Cache Aware/Software Prefetching based GPU Algorithms
In this project, we studied different parallel convex hull algorithms for GPU and their memory access patterns. We then identified the best parallel convex hull algorithm and introduced cache aware software prefetching techniques to improve efficiency. Also we conducted experimentations using latest GPUs like NVIDIA GTX 580/680 that has cache system and reported the results for comparison.
Face Recognition using Eigen Faces
We implemented a face recognition system using PCA (Principle Component Analysis) and SVM (Support Vector Machines). PCA reduces the high dimensional image to a low dimensional space (referred to as eigen space). Computing the eigen vectors of scatter matrix (of the training samples) and selecting Top k eigen vectors are two key tasks in this process. We have implemented the above techniques on standard datasets maintained by Yale University, CMU University and also on a real time dataset generated during CSE471(Statistical Methods in AI) class at IIIT Hyderabad. We also performed validation & verification experiments on these datasets with the above mentioned techniques, recorded results and inferences.
POS Tagging and CYK Parsing for Indian Languages
We implemented POS taggers for Hindi, Tamil and Telugu using supervised (Hidden Markov Model) and unsupervised (clustering) approaches. We also used CYK algorithm on datasets of these languages. Python was used for programming.
Effective Text Categorization Using Compactness & Position of First Appearance
Our project automatically sorts a set of documents into categories from a predefined set. In constrast to using the traditional term frequency values solely, including the distributional features requires only a little bit additional cost, while the categorization performance was significantly improved.
