Efficiently Mining Frequent Trees in a Forest
, 2002
"... Mining frequent trees is very useful in domains like bioinformatics, web mining, mining semi-structured data, and so on. We formulate the problem of mining (embedded) subtrees in a forest of rooted, labeled, and ordered trees. We present TreeMiner, a novel algorithm to discover all frequent subtrees ..."

subtrees in a forest, using a new data structure called scope-list. We contrast TreeMiner with a pattern matching tree mining algorithm (PatternMatcher). We conduct detailed experiments to test the performance and scalability of these methods. We find that TreeMiner outperforms the pattern matching
Statistical properties of community structure in large social and information networks
"... A large body of work has been devoted to identifying community structure in networks. A community is often though of as a set of nodes that has more connections between its members than to the remainder of the network. In this paper, we characterize as a function of size the statistical and structur ..."

of what one would expect based on experience with and intuition from expander graphs, from graphs that are well-embeddable in a low-dimensional structure, and from small social networks that have served as testbeds of community detection algorithms. We have found, however, that a generative model
Psychophysical evidence for separate channels for the perception of form, color, movement and depth
- J. Neurosci
, 1987
"... Physiological and anatomical findings in the primate visual system, as well as clinical evidence in humans, suggest that different components of visual information processing are segregated into largely independent parallel pathways. Such a segregation leads to certain predictions about human vision ..."

vision. In this paper we describe psychophysical experiments on the interactions of color, form, depth, and movement in human perception, and we attempt to correlate these aspects of visual perception with the different subdivisions of the visual system. It is function that breathes life into anatomy
C4.5 Decision Forests
- Proceedings of the 3rd International Conference on Document Analysis and Recognition
, 1995
"... Much of previous attention on decision trees focuses on the splitting criteria and optimization of tree sizes. The dilemma between overfitting and achieving maximum accuracy is seldom resolved. We propose a method to construct a decision tree based classifier that maintains highest accuracy on train ..."

"... This paper presents a computational effective framework for tracking and pose estimation of vehicles in videos reaching comparable performance to state-of-the-art methods. We cast the problem of vehicle tracking as ranking possible poses for each frame and connecting subsequent poses by exploiting a ..."

The carbon balance of tropical, temperate and boreal forests.
- Plant Cell and Environment,
, 1999
"... ABSTRACT Forest biomes are major reserves for terrestrial carbon, and major components of global primary productivity. The carbon balance of forests is determined by a number of component processes of carbon acquisition and carbon loss, and a small shift in the magnitude of these processes would ha ..."

As is the case for many boreal forests At the other extreme, the forest in central Amazonia experiences year-round warm temperatures, and comparatively small ranges of diurnal and seasonal temperature and day length. Annual precipitation is high, but shows significant interannual variability and, despite
