Balanced Splitting on Weighted Intervals
Interval splitting Combinatorial optimizations Algorithms Temporal databases Multi-version databases
2016/1/22
We study a problem on splitting intervals. Let I be a set of n intervals on a line L, with non-negative weights. Given any integer k ≥ 1, we want to find k points on L to partition L into k + 1 segmen...

Machine statistics data sets convex optimization the model data collection processing machine
2015/8/7
Machine learning and statistics with very large datasets is now a topic of widespread interest, both in academia and industry. Many such tasks can be posed as convex optimization problems, so algorith...
Metric selection in fast dual forward backward splitting
The gradient data optimization index space
2015/8/7
The performance of fast forward-backward splitting, or equivalently fast proximal gradient methods, is susceptible to conditioning of the optimization problem data. This conditioning is related to a m...

The coupling of groundwater movement and reactive transport during groundwater recharge with wastewater leads to a complicated mathematical model, involving terms to describe convection-dispersion, ad...
AN AUTO-REGRESSIVE MODEL FOR CHECKBOARD SPLITTING BASED WYNER-ZIV CODING
auto-regressive side information chessboard splitting wyner-ziv
2013/7/16
An auto-regressive (AR) based side information (SI) generation is proposed in this paper for block based chessboard pattern Wyner-Ziv (WZ) coding, where each WZ frame is split into two sets at encoder...
