On the Convergence of Tsetlin Machines for the XOR Operator

6 code implementations7 Jan 2021 Lei Jiao, Xuan Zhang, Ole-Christoffer Granmo, K. Darshana Abeyrathna

The Tsetlin Machine (TM) is a novel machine learning algorithm with several distinct properties, including transparent inference and learning using hardware-near building blocks.

Massively Parallel and Asynchronous Tsetlin Machine Architecture Supporting Almost Constant-Time Scaling

2 code implementations10 Sep 2020 K. Darshana Abeyrathna, Bimal Bhattarai, Morten Goodwin, Saeed Gorji, Ole-Christoffer Granmo, Lei Jiao, Rupsa Saha, Rohan K. Yadav

We evaluated the proposed parallelization across diverse learning tasks and it turns out that our decentralized TM learning algorithm copes well with working on outdated data, resulting in no significant loss in learning accuracy.

A Novel Multi-Step Finite-State Automaton for Arbitrarily Deterministic Tsetlin Machine Learning

no code implementations4 Jul 2020 K. Darshana Abeyrathna, Ole-Christoffer Granmo, Rishad Shafik, Alex Yakovlev, Adrian Wheeldon, Jie Lei, Morten Goodwin

However, TMs rely heavily on energy-costly random number generation to stochastically guide a team of Tsetlin Automata to a Nash Equilibrium of the TM game.

Extending the Tsetlin Machine With Integer-Weighted Clauses for Increased Interpretability

4 code implementations11 May 2020 K. Darshana Abeyrathna, Ole-Christoffer Granmo, Morten Goodwin

Here, we address the accuracy-interpretability challenge in machine learning by equipping the TM clauses with integer weights.

A Regression Tsetlin Machine with Integer Weighted Clauses for Compact Pattern Representation

4 code implementations4 Feb 2020 K. Darshana Abeyrathna, Ole-Christoffer Granmo, Morten Goodwin

Although the RTM has solved non-linear regression problems with competitive accuracy, the resolution of the output is proportional to the number of clauses employed.

A Scheme for Continuous Input to the Tsetlin Machine with Applications to Forecasting Disease Outbreaks

4 code implementations10 May 2019 K. Darshana Abeyrathna, Ole-Christoffer Granmo, Xuan Zhang, Morten Goodwin

In this paper, we apply a new promising tool for pattern classification, namely, the Tsetlin Machine (TM), to the field of disease forecasting.

The Regression Tsetlin Machine: A Tsetlin Machine for Continuous Output Problems

1 code implementation10 May 2019 K. Darshana Abeyrathna, Ole-Christoffer Granmo, Lei Jiao, Morten Goodwin

We achieve this by: (1) using the conjunctive clauses of the TM to capture arbitrarily complex patterns; (2) mapping these patterns to a continuous output through a novel voting and normalization mechanism; and (3) employing a feedback scheme that updates the TM clauses to minimize the regression error.
