Machine learning is employed for myriad of applications ranging from engineering to non-engineering, medical to finance, sports to studies and many more. The huge demand for machine learning has spearheaded various techniques such as Hidden Markov Models (HMM), Artificial Neural Networks(ANN), Support Vector Machines (SVM), Relevance Vector Machines (RVM) and many more.

Machine learning is employed for myriad of applications ranging from engineering to non-engineering, medical to finance, sports to studies and many more. The huge demand for machine learning has spearheaded various techniques such as Hidden Markov Models (HMM), Artificial Neural Networks(ANN), Support Vector Machines (SVM), Relevance Vector Machines (RVM) and many more. It is well reported in literature that RVM outperforms SVM interms of sparseness as well as accuracy and hence the same is employed for the proposed work. In this paper, stock market prediction using optimum threshold based RVM is reported and its performance is evaluated using given input parameters for share market. In order to assess the performance of the proposed system, datasets from the following four stock exchanges are considered for evaluation, which includes NASDAQ, National Security Exchange (NSE), New York Stock Exchange (NYSE) and London Stock Exchange (LSE). It is observed that 19.17 - 83.33% of relevance vectors are pruned on using the proposed optimum threshold based RVM technique. Also a user friendly Graphical user interface is developed for the proposed work, which can be easily extended for various other machine learning applications too. Show less

Face recognition has found a variety of applications in consumer electronics, such as laptops, smart phones, home security systems, home automation systems and many more. Machine learning is one of the important concepts, required for designing any pattern recognition system, including the proposed real-time face recognition system. Relevance vector machine is considered as one of the most recent machine learning algorithms reported in literature. In this paper, design and evaluation of Relevance Vector Machine classifier architectures for a real-time face recognition system using Histogram of Oriented Gradient features is proposed. In order to assess the performance of system designed, AT&T database of faces are initially considered, followed by the performance evaluation using real-time face inputs from the system camera. 81.25-97.00% recognition accuracy is obtained on using the proposed system and the proposed work can be easily extended for various other pattern recognition systems too.
