  • Adaptive Sparse Representation of Continuous Input for Tsetlin Machines Based on Stochastic Searching on the Line
    electronics Article Adaptive Sparse Representation of Continuous Input for Tsetlin Machines Based on Stochastic Searching on the Line Kuruge Darshana Abeyrathna *, Ole-Christoffer Granmo and Morten Goodwin Centre for Artificial Intelligence Research, University of Agder, 4870 Grimstad, Norway; [email protected] (O.-C.G.); [email protected] (M.G.) * Correspondence: [email protected] Abstract: This paper introduces a novel approach to representing continuous inputs in Tsetlin Machines (TMs). Instead of using one Tsetlin Automaton (TA) for every unique threshold found when Booleanizing continuous input, we employ two Stochastic Searching on the Line (SSL) automata to learn discriminative lower and upper bounds. The two resulting Boolean features are adapted to the rest of the clause by equipping each clause with its own team of SSLs, which update the bounds during the learning process. Two standard TAs finally decide whether to include the resulting features as part of the clause. In this way, only four automata altogether represent one continuous feature (instead of potentially hundreds of them). We evaluate the performance of the new scheme empirically using five datasets, along with a study of interpretability. On average, TMs with SSL feature representation use 4.3 times fewer literals than the TM with static threshold-based features. Furthermore, in terms of average memory usage and F1-Score, our approach outperforms simple Multi-Layered Artificial Neural Networks, Decision Trees, Support Vector Machines, K-Nearest Neighbor, Random Forest, Gradient Boosted Trees (XGBoost), and Explainable Boosting Machines (EBMs), as well as the standard and real-value weighted TMs. Our approach further outperforms Citation: Abeyrathna, K.D.; Granmo, Neural Additive Models on Fraud Detection and StructureBoost on CA-58 in terms of the Area Under O.-C.; Goodwin, M.

  • Coalesced Multi-Output Tsetlin Machines with Clause Sharing∗
    Coalesced Multi-Output Tsetlin Machines with Clause Sharing∗ Sondre Glimsdal† and Ole-Christoffer Granmo‡ August 18, 2021 Abstract Using finite-state machines to learn patterns, Tsetlin machines (TMs) have obtained competitive accuracy and learning speed across several benchmarks, with frugal memory- and energy footprint. A TM represents patterns as conjunctive clauses in propositional logic (AND-rules), each clause voting for or against a particular output. While efficient for single-output problems, one needs a separate TM per output for multi-output problems. Employing multiple TMs hinders pattern reuse because each TM then operates in a silo. In this paper, we introduce clause sharing, merging multiple TMs into a single one. Each clause is related to each output by using a weight. A positive weight makes the clause vote for output 1, while a negative weight makes the clause vote for output 0. The clauses thus coalesce to produce multiple outputs. The resulting coalesced Tsetlin machine (CoTM) simultaneously learns both the weights and the composition of each clause by employing interacting Stochastic Searching on the Line (SSL) and Tsetlin automata (TAs) teams. Our empirical results on MNIST, Fashion-MNIST, and Kuzushiji-MNIST show that CoTM obtains significantly higher accuracy than TM on 50- to 1K-clause configurations, indicating an ability to repurpose clauses. E.g., accuracy goes from 71:99% to 89:66% on Fashion- MNIST when employing 50 clauses per class (22 Kb memory). While TM and CoTM accuracy is similar when using more than 1K clauses per class, CoTM reaches peak accuracy 3ˆ faster on MNIST with 8K clauses.

  • Text Classification with Noisy Class Labels
    Text Classification with Noisy Class Labels By Andrea Pagotto A thesis proposal submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfilment of the requirements for the degree of Master of Computer Science Ottawa-Carleton Institute for Computer Science School of Computer Science Carleton University Ottawa, Ontario June 2020 ⃝c Copyright 2020, Andrea Pagotto The undersigned hereby recommend to the Faculty of Graduate and Postdoctoral Affairs acceptance of the thesis, Text Classification with Noisy Class Labels submitted by Andrea Pagotto Dr. Michel Barbeau (Director, School of Computer Science) Dr. B. John Oommen (Thesis Supervisor) Carleton University June 2020 ii ABSTRACT Text classification is a sub-field of Natural Language Processing (NLP), thatin- volves mapping an input text document to an output topic or label. There are nu- merous practical applications for text classification, including email spam detection, identifying sentiments in social media, news topic detection, and many more. Due to the importance of the field, there has been much related research in recent years. Our work in this thesis specifically focuses on the problem of text classification in the setting of a Random Environment. The Random Environment in this application would be noise in the labels of the training data. Label noise is an important issue in classification, with many potential negative consequences, such as decreasing the accuracy of the predictions, and increasing the complexity of the trained models. Designing learning algorithms that help maximize a desired performance measure in such noisy settings, is very valuable for achieving success on real world data. This thesis also investigates a recently proposed classification method that in- volves the use of Learning Automata (LA) for text classification.

Feature extraction is Natural Language Processing (NLP) as well as Information Retrieval done using various lexical, syntactic features and parts of speech. (IR). Among various domains of QA, Question Classification (QC) Most of the machine learning algorithms are powerful to obtain is a very important system that classifies a question based on the good accuracy with QC data [17]. However, there always exists type of answer expected from it. Generalization is a very important a limitation of interpretation in the model.

  • Friday, May 15, 2020 the University of Arizona
    FRIDAY, MAY 15, 2020 THE UNIVERSITY OF ARIZONA It was in 1885 that the Thirteenth Territorial Legislature founded the University of Arizona with an appropriation of $25,000 — but no land. This appropriation was not welcomed by many residents of Tucson and Pima County, as they were looking for either the state Capitol building, a prison, or even an asylum for the insane — but definitely not a university. The money would be available on the condition that the community provided a suitable site. Just before the $25,000 was to be returned to the Legislature, two gamblers and a saloon-keeper donated 40 acres of land “way out east of town,” and thus the University could become a reality. Classes began in 1891 with 32 students and six teachers, all accommodated in one building. The first class graduated in 1895, when three students received their degrees. Today, the University of Arizona is one of the nation's top public universities, according to U.S. News & World Report. It has grown to more than 45,000 students and 15,000 faculty and staff members across the University, which includes the main campus, the College of Applied Science & Technology in Sierra Vista, the College of Medicine – Phoenix and Arizona Online. The University is organized into 21 colleges and 23 schools. It is one of the top 10 employers in Arizona, with an economic impact of more than $1 billion in fiscal year 2017 as a result of the University’s research expenditures. 156th Annual Arizona COMMENCEMENT Table of Contents STREAMED PROGRAM · · · · · · · · · · · · · · · ·
