ProCode: A Proactive Erasure Coding Scheme for Cloud Storage Systems

- Peng Li, J. Li, R. Stones, G. Wang, Zhongwei Li, X. Liu
- Computer Science
- IEEE 35th Symposium on Reliable Distributed…
- 1 September 2016

Common distributed storage systems use data replication to improve system reliability and maintain data availability, but at the cost of disk storage. In order to lower storage costs, data may… Expand

Selective Term Proximity Scoring Via BP-ANN

When two terms occur together in a document, the probability of a close relationship between them and the document itself is greater if they are in nearby positions. However, ranking functions… Expand

Being Accurate Is Not Enough: New Metrics for Disk Failure Prediction

- J. Li, R. Stones, G. Wang, Zhongwei Li, X. Liu, K. Xiao
- Computer Science
- IEEE 35th Symposium on Reliable Distributed…
- 1 September 2016

Traditionally, disk failure prediction accuracy is used to evaluate disk failure prediction model. However, accuracy may not reflect their practical usage (protecting against failures, rather than… Expand

GPU MrBayes V3.1: MrBayes on Graphics Processing Units for Protein Sequence Data.

We present a modified GPU (graphics processing unit) version of MrBayes, called ta(MC)(3) (GPU MrBayes V3.1), for Bayesian phylogenetic inference on protein data sets. Our main contributions are 1)… Expand

Hard drive failure prediction using Decision Trees

This paper proposes two hard drive failure prediction models based on Decision Trees (DTs) and Gradient Boosted Regression Trees (GBRTs) which perform well in prediction performance as well as… Expand

Leveraging Context-Free Grammar for Efficient Inverted Index Compression

- Zhaohua Zhang, J. Tong, +5 authors X. Liu
- Computer Science
- SIGIR '16
- 7 July 2016

Large-scale search engines need to answer thousands of queries per second over billions of documents, which is typically done by querying a large inverted index. Many highly optimized integer… Expand

A Latin square autotopism secret sharing scheme

- R. Stones, Ming Su, X. Liu, G. Wang, Sheng Lin
- Computer Science, Mathematics
- Des. Codes Cryptogr.
- 1 September 2016

We present a novel secret sharing scheme where the secret is an autotopism (a symmetry) of a Latin square. Previously proposed secret sharing schemes involving Latin squares have many drawbacks: (a)… Expand

Lazy exact deduplication

- Jingwei Ma, R. Stones, +4 authors X. Liu
- Computer Science
- 32nd Symposium on Mass Storage Systems and…
- 10 June 2017

During data deduplication, on-disk fingerprint lookups lead to high disk traffic, resulting in a bottleneck. In this paper, we propose a “lazy” data deduplication method which buffers incoming… Expand

Computing the number of h-edge spanning forests in complete bipartite graphs

- Discret. Math. Theor. Comput. Sci.
- 5 December 2014

Let fm,n,h be the number of spanning forests with h edges in the complete bipartite graph Km,n. Kirchhoff\textquoterights Matrix Tree Theorem implies fm,n,m+n-1=mn-1 nm-1 when m ≥1 and n ≥1, since… Expand

Efficient GPU-Based Query Processing with Pruned List Caching in Search Engines

- Computer Science
- IEEE 23rd International Conference on Parallel…
- 1 December 2017

There are two inherent obstacles to effectively using Graphics Processing Units (GPUs) for query processing in search engines: (a) the highly restricted GPU memory space, and (b) the CPU-GPU transfer… Expand
