    Javafastcomplex

    Javafastcomplex has both mutable and immutable complex numbers

    ...Mutable complex numbers can then be used in the most performance-critical parts of the code with immutable complex numbers being used elsewhere. Performance improvement of mutable complex numbers is 10x in the best-case scenario and about 2x in real life complex number code. The package is released under the liberal MIT license.

    Semantic query optimization (SQO) is the process of finding equivalent rewritings of an input query given constraints that hold in a database instance. We present a Chase & Backchase (C&B) algorithm strategy that generalizes and improves on well-known methods in the field. The implementation of our approach, the pegasus system, outperforms existing C&B systems an average by two orders of magnitude. This gain in performance is due to a combination of novel methods that lower the complexity...

    JActor

    JActor

    High Performance, Lock Free Java Actors

    JActor is a high-performance actor framework designed to make vertical scalability easy. JActor achieves its speed, in part, by almost always executing synchronously--though it is easy enough to force asynchronous processing when needed. JActor is divided into several GitHub projects: JActor - https://github.com/laforge49/JActor JID - https://github.com/laforge49/JID JFile - https://github.com/laforge49/JFile JANetty - https://github.com/kumarshantanu/JANetty

    AdPreqFr4SL

    Adaptive Prequential Learning Framework

    The AdPreqFr4SL learning framework for Bayesian Network Classifiers is designed to handle the cost / performance trade-off and cope with concept drift. Our strategy for incorporating new data is based on bias management and gradual adaptation. Starting with the simple Naive Bayes, we scale up the complexity by gradually updating attributes and structure. Since updating the structure is a costly task, we use new data to primarily adapt the parameters and only if this is really necessary, do we...

    SweetOnionCCG2PTBConverter

    A tool that converts CCGBank to PTB

    Conversion between different grammar frameworks is of great importance to comparative performance analysis of the parsers developed on them. This tool can convert CCG derivations to PTB trees by using Max Entropy models as well as visualizing the tree graphs. The main technical innovation presented here is the effective conversion method which achieves a F score over 95%.
