Adaptive program optimizations, such as automatic selection of the expected fastest implementation variant for a computation component depending on runtime context, are important especially for heterogeneous computing systems but require good performance models. Empirical performance models based on trial executions which require no or little human efforts show more practical feasibility if the sampling...
Protocols such as TCP depend on loss detection and recovery algorithms to provide a reliable data delivery service. TCP detects loss events using either retransmission timeout or receipt of duplicate acknowledgements. Since, TCP does not have any explicit knowledge about the cause of packet loss, it always treats it as a congestion indication and then adjusts sending rate conservatively to maintain...
An efficient approach to detect and localize dining plates in images and videos based on human vision is reported in this paper. Rapid processing is achieved by using random checkpoints on edges only, simulating the knowledge based target search in biological visual systems. A new grouping algorithm based on convexity is presented for a top-down segmentation of candidate objects. Our experiments demonstrate...
Responsive transport protocols e.g. TCP, back-off on packet loss. This is because packet loss is by default treated as a sign of congestion. However losses in a wireless network may not only arise from congestion but also because of the inherent characteristics of the wireless medium. If a TCP source assumes a wireless loss as a loss due to congestion and reduces its transmission rate, it fails to...
