Episode Rule Mining is a popular framework for discovering sequential rules from event sequential data. However, traditional episode rule mining methods only tell that the consequent event is likely to happen within a given time intervals after the occurrence of the antecedent events. As a result, they cannot satisfy the requirement of many time sensitive applications, such as program security trading...
Frequent episode mining is a popular framework for discovering sequential patterns from sequence data. Previous studies on this topic usually process data offline in a batch mode. However, for fast-growing sequence data, old episodes may become obsolete while new useful episodes keep emerging. More importantly, in time-critical applications we need a fast solution to discovering the latest frequent...
The mass matrix resulting from a finite-element-method (FEM) based electromagnetic analysis possesses favorable properties that can be exploited to reduce the computational time and memory cost for large-scale circuit modeling. In this paper, a mass-matrix based frequency-domain FEM method is developed for the analysis of integrated circuits. Its convergence is theoretically proved, and its efficiency...
In this work, the authors developed a fast electromagnetics-based nonlinear-linear co-simulation algorithm based on a recently developed time-domain orthogonal finite-element reduction-recovery method (OrFE-RR). In this method, the linear part and the nonlinear part are naturally decoupled due to the diagonal matrix in the single surface system. Meanwhile, as the devices are usually not connected...
A fast electromagnetic simulator is developed to co-simulate the linear network and nonlinear circuits in an integrated circuit system. In this simulator, the physical layout of a large-scale linear network is rigorously reduced to a single surface or a few surfaces where the nonlinear circuits are located. The reduction is done analytically, and, hence, the computational overhead is minimal. The...
The scaling of supply voltages and the increased level of integration have conspired to make the analysis and design of microelectronic systems increasingly challenging. The impact of dynamic noise due to signal switching, die-package coupling, power management techniques, substrate coupling, etc., can been seen at all levels of a power delivery network, from chip to package to mother board to the...
This paper proposes a hierarchical and adaptive finite-element reduction-recovery method for power and signal integrity analysis of high-speed IC and packaging structures. This method rigorously reduces the matrix of a multilayer system of O(N) to that of a single-cell one of O(1) regardless of the original problem size. More important, the matrix reduction is achieved analytically, and hence the...
