  • Title: Grammar-guided Feature Extraction from Signals and Images
    Institute: ISTI ISSDM
    • Description:

      Image and signal sensors collect data at increasingly greater rates, making it a great challenge to search and organize data in archives. Work is underway to engage the sensor, data management, and machine learning expertise of LANL and UCSC to tackle adaptive, content-based search in large remote sensing archives. We demonstrate the utility of a new method for extracting features from imagery and signals to adi the archival search problem.

  • Title: CASCC: A Fast Algorithm for Time Series Classification
    Institute: ISTI ISSDM
    • Description:

      CASCC is a new algorithm for classifying time series. It is highly competitive in terms of speed and accuracy compared to many other algorithms. It is inspired by another leading alghorthm DTW-1NN howerver does not suffer the same computational limitations when applying the model to new time series.

  • Title: Alternative Reliability Models in Ceph
    Institute: ISTI ISSDM
    • Description:

      RAID systems have traditionally offered increased performance and data security in small storage systems. An opportunitynow exists to extend traditional RAID principles into the area of large-scale object-based storage devices in order to offer greater data security and space efficiency. In a system where component failures can be expected on a daily basis, the importance of redundancy mechanisms is obvious, and RAID principles offer an appropriate model. Ceph is an excellent platform with whic

  • Title: Boosting for Image Recognition
    Institute: ISTI ISSDM
    • Description: The ISIS team in ISR-2 primarily uses supervised learning techniques to solve classification problems in imagery and therefore has a strong interest in finding linear classification algorithms that are both robust and efficient. Boosting algorithms take a principled approach to finding linear classifiers and they has been shown to be so effective in practice that they are widely used in a variety of domains. In this proposal we present evidence that smoothing is not necessarily the optimal way

  • Title: Exploring Uncetainty Visualization in Large Data Sets
    Institute: ISTI ISSDM
    • Description: The size of the data sets and the uncertainty in the data sets come from the fact that we are dealing with ensemble data sets. These are usually from monte carlo simulations where each output (out of many runs) represents a possible solution. The degree of agreement (or disagreement) provides some indications of certainty (or uncertainty) about the results. Because monte carlo simulations can potentially involve large number of repetitions, the total data size can very quickly get very large eve

  • Title: Sensing Human Shape and Motion
    Institute: ISTI ISSDM
    • Description: The research objective of this proposal is to measure human body shape and motion without augmenting the subject. The hypothesis is that replacing traditional cameras with high accuracy 3D shape measurement devices and utilizing a carefully constructed prior model of human surface shape are the critical factors that have been missing from prior attempts to meet this goal. The long term accuracy targets are shape to 1mm and motion to 1deg.

information. We will also develop an adaptive information filtering to find,
filter and condense the information available on the web.
