In this paper, we describe the Artificial Intelligence and Information Analysis (AIIA) laboratory approach for shot boundary detection as applied to the TRECVID 2006 video retrieval benchmark. The paper describes the approach as well as the performance analysis. The method relies on evaluating mutual information between multiple pairs of frames within a certain temporal window. The performance ...

Power Spectral Density (PSD) computed by taking the Fourier transform of auto-correlation functions (WienerKhintchine Theorem) gives better result, in case of noisy data, as compared to the Periodogram approach. However, the computational complexity of Wiener-Khintchine approach is more than that of the Periodogram approach. For the computation of short time Fourier transform (STFT), this probl...

The previous work is carried out on sliding window approach for fragment mining rules which results in large & complex processing the data. In this paper we present an idea to find out association within inter-transaction with different windowing approach. These approaches first minimizes the huge input dataset using tumbling window approach and then apply fragment mining to generate rules amon...

In this paper, we propose a data-driven sliding window approach to solve log-optimal portfolio problem. contrast many of the existing papers, leads trading strategy with time-varying weights rather than fixed constant weights. We show, by conducting various empirical studies, that possesses superior performance classical in sense having higher cumulative rate returns.
