An efficient distributed system for mining sequential patterns

, 2010
碩士本研究以提昇循序樣本探勘(sequential pattern mining)之效率為目標，發展以多部電腦為基礎的分散式探勘系統。分散式探勘首重節點間的負載平衡，同時需降低節點間通訊負擔。負載平衡與通訊負擔的降低均有賴於準確的任務工作量預測，此外，也應避免透過繁複的任務重分配來解決負載失衡的狀況。 針對上述重點，本研究首先針對相關文獻中常利用之工作量預測方法進行分析，發現以序列(sequence)支持度(support)為基礎之預測方式與實際狀況差異甚大，將嚴重影響負載平衡。此外 ...

Sequential Pattern Mining on Multimedia Data. [PDF]

, 2015
Analyzing multimedia data is a challenging problem due to the quantity and complexity of such data. Mining for frequently recurring patterns is a task often ran to help discovering the underlying structure hidden in the data. In this article, we propose audio data symbolization and sequential pattern mining methods to extract patterns from audio ...

Sequential Pattern Mining by Pattern-Growth: Principles and Extension

, 2005
Sequential pattern mining is an important data mining problem with broad applications. However, it is also a challenging problem since the mining may have to generate or examine a combinatorially explosive number of intermediate subsequences.

A New Customizable Surfactant LLPS Strategy for Sustainable and Highly Efficient Radioactive Metal Ion Separation

Advanced Science, EarlyView.
A diluent‐free, customizable liquid–liquid phase separation (LLPS) platform enables highly efficient radioactive metal ion extraction and stripping. By encapsulating hydrophobic extractants into an ionic surfactant‐rich condensed phase, this LLPS system leverages synergistic electrostatic and coordination interactions.

Natural Resistance to Ovarian Hyperstimulation Syndrome in Estrildid Finches Reveals Macrophage GPR183 as a Potential Therapeutic Target

Advanced Science, EarlyView.
Ovarian macrophage depletion reverses OHSS resistance in estrildid finches and exacerbates OHSS symptoms in rats. Activating macrophage GPR183 alleviates OHSS by reducing pro‐inflammatory factors, increasing immunomodulatory molecules, remodeling CD44/SDC4‐mediated communication, and restoring immune homeostasis.

Transposase‐Assisted Donor Tethering Boosts Large‐Fragment HDR in Plants

Advanced Science, EarlyView.
A transposase‐assisted donor tethering strategy is developed to enhance homology‐directed repair in plants. By recruiting donor DNA to double‐strand breaks and synergizing with repair pathway reprogramming and transcription‐coupled donor design, this system markedly improves large‐fragment targeted insertion efficiency, providing a robust platform for ...

Incremental Mining of Across-streams Sequential Patterns in Multiple Data Streams

, 2012
Sequential pattern mining is the mining of data sequences for frequent sequential patterns with time sequence, which has a wide application. Data streams are streams of data that arrive at high speed. Due to the limitation of memory capacity and the need
