    Algebra of Data Reconciliation By Elod Csirmaz and Laszlo Csirmaz. A new paper on the algebra of data synchronisation which contains stronger and more rigorous results than before, and extends their scope to more data types. We investigate the algebraic properties of filesystem command sequence pairs that are applicable to the same data structure, and use these results to show that the reconciliation problem has a unique maximal solution. The syntactical properties of this solution also allow for an efficient algorithm to produce it. Available on arXiv.org. More »
  • Diagram of neural network
    Interpreting Neural Networks by Reducing Nonlinearities during Training A short paper and sample code demonstrating a simple solution that makes it possible to extract rules from a neural network that employs Parametric Rectified Linear Units (PReLUs). We introduce a force, applied in parallel to backpropagation, that aims to reduce PReLUs into the identity function, which then causes the neural network to collapse into a smaller system of linear functions and inequalities suitable for review or use by human decision makers.

  • Computer Science
    Algebraic File Synchronization: Adequacy and Completeness In this paper we investigate file synchronization. We define algorithms for update detection and reconciliation over an algebraic system of filesystem operations with high information content, and present rigorous proofs that they work as intended and cannot be improved on.

    A Transmission Protocol over the LP Port and , “Egy kommunikációs protokoll [A Transmission Protocol over the LP port],” in Híradástechnika /03, 42–46. We present and test a communication protocol using the line printer port with automatic synchronisation where bits or trits are transmitted as state changes.

Software

  • Superloop RNN models
    Superloop: Complex RNN Models A "superloop" is an extra loop that connects the output of a recursive neural network (RNN) back to its input in the next timestep via one or more external systems. This project contains: a framework to build RNNs with a superloop in TensorFlow/Keras, an implementation of a simple gated recurrent unit, an implementation of a register-based memory unit, and an implementation of an attention system that allows the network to move freely along the input data.

  • Trainable clustering
    Trainable Online Clustering Exploring recognizing unseen clusters with a neural network. Given an initial, labeled batch of data, we aim to train a system that is capable of classifying a stream of data and recognizing new classes it has not yet seen. More and get the code »
