Identifying Time-Lagged Gene Clusters on Gene Expression Data
Motivation: Analysis of gene expression data can provide insights into the time-lagged co-regulations of genes/gene clusters. However, existing methods such as Event Method and Edge Detection Method are inefficient as they only compare two genes each time. More importantly, they lose some important information due to their scoring criterion. In this paper, we propose an efficient algorithm to i...
متن کاملA Hybrid Time Lagged Network for Predicting Stock Prices
Traditionally, technical analysis approach, that predicts stock prices based on historical prices and volume, basic concepts of trends, price patterns and oscillators, is commonly used by stock investors to aid investment decisions. Advanced intelligent techniques, ranging from pure mathematical models and expert systems to neural networks, have also been used in many financial trading systems ...
متن کاملA pattern recognition approach to infer time-lagged genetic interactions
MOTIVATION For any time-course microarray data in which the gene interactions and the associated paired patterns are dependent, the proposed pattern recognition (PARE) approach can infer time-lagged genetic interactions, a challenging task due to the small number of time points and large number of genes. PARE utilizes a non-linear score to identify subclasses of gene pairs with different time l...
متن کاملLagged cells.
The timing of the retinal input to the lateral geniculate nucleus is highly modified in lagged cells. Evidence is reviewed for how the responses of these cells are generated, how their structure and function differs from their nonlagged neighbors, and what their projections to cortex might do.
متن کاملAn Ordered Lasso and Sparse Time-Lagged Regression
We consider a regression scenario where it is natural to impose an order constraint on the coefficients. We propose an order-constrained version of `1-regularized regression (lasso) for this problem, and show how to solve it efficiently using the well-known Pool Adjacent Violators Algorithm as its proximal operator. The main application of this idea is to time-lagged regression, where we predic...
