Using Tsetlin Machine to discover interpretable rules in natural language processing applications
2021
Tsetlin Machines (TM) use finite state machines for learning and propositional logic to represent patterns. The resulting pattern recognition approach captures information in the form of conjunctive clauses, thus facilitating human interpretation. In this work, we propose a TM-based approach to three common natural language processing (NLP) tasks, namely, sentiment analysis, semantic relation categorization and identifying entities in multi-turn dialogues. By performing frequent itemset mining on the TM-produced patterns, we show that we can obtain a global and a local interpretation of the learning, one that mimics existing rule-sets or lexicons. Further, we also establish that our TM base…
A vision system for symbolic interpretation of dynamic scenes using arsom
2001
We describe an artificial high-level vision system for the symbolic interpretation of data coming from a video camera that acquires the image sequences of moving scenes. The system is based on ARSOM neural networks that learn to generate the perception-grounded predicates obtained by image sequences. The ARSOM neural networks also provide a three-dimensional estimation of the movements of the relevant objects in the scene. The vision system has been employed in two scenarios: the monitoring of a robotic arm suitable for space operations, and the surveillance of an electronic data processing (EDP) center.
Unbiased sensitivity analysis and pruning techniques in neural networks for surface ozone modelling
2005
Abstract This paper presents the use of artificial neural networks (ANNs) for surface ozone modelling. Due to the usual non-linear nature of problems in ecology, the use of ANNs has proven to be a common practice in this field. Nevertheless, few efforts have been made to acquire knowledge about the problems by analysing the useful, but often complex, input–output mapping performed by these models. In fact, researchers are not only interested in accurate methods but also in understandable models. In the present paper, we propose a methodology to extract the governing rules of trained ANN which, in turn, yields simplified models by using unbiased sensitivity and pruning techniques. Our propos…
Intrusion Detection with Interpretable Rules Generated Using the Tsetlin Machine
2020
The rapid deployment in information and communication technologies and internet-based services have made anomaly based network intrusion detection ever so important for safeguarding systems from novel attack vectors. To this date, various machine learning mechanisms have been considered to build intrusion detection systems. However, achieving an acceptable level of classification accuracy while preserving the interpretability of the classification has always been a challenge. In this paper, we propose an efficient anomaly based intrusion detection mechanism based on the Tsetlin Machine (TM). We have evaluated the proposed mechanism over the Knowledge Discovery and Data Mining 1999 (KDD’99) …
Interpretācija kā mākslas darba nosacījums: Hansa Georga Gadamera un Artūra Danto teoriju salīdzinājums
2021
Bakalaura darba mērķis ir pierādīt, ka atšķirības Artūra Kolmena Danto un Hansa Georga Gadamera mākslas teorijās izriet no atšķirīga interpretācijas jēdziena traktējuma. Pirmajās divās nodaļās uzrādīšu to, kā interpretācija saistās ar mākslu katras teorijas ietvaros, bet trešajā nodaļā no interpretācijas jēdziena skatupunkta salīdzināšu līdzīgos un atšķirīgos aspektus abās pieejās. Kā galvenos saskares punktus starp abiem domātājiem identificēju: (1) Georga Vilhelma Frīdriha Hēgeļa ideju turpināšanu un iestrādāšanu savās teorijās, (2) klasiskās un modernās mākslas pretnostatījuma pārvarēšanu, savienojot abu veidu mākslas vienā izpratnes shēmā, (3) interpretācijas izvirzīšanu par galveno nos…

GW170817, General Relativistic Magnetohydrodynamic Simulations, and the Neutron Star Maximum Mass
2017
Recent numerical simulations in general relativistic magnetohydrodynamics (GRMHD) provide useful constraints for the interpretation of the GW170817 discovery. Combining the observed data with these simulations leads to a bound on the maximum mass of a cold, spherical neutron star (the TOV limit): ${M_{\rm max}^{\rm sph}}\lesssim 2.74/\beta$, where $\beta$ is the ratio of the maximum mass of a uniformly rotating neutron star (the supramassive limit) over the maximum mass of a nonrotating star. Causality arguments allow $\beta$ to be as high as $1.27$, while most realistic candidate equations of state predict $\beta$ to be closer to $1.2$, yielding ${M_{\rm max}^{\rm sph}}$ in the range $2.16…

The Cultivation of Astronomy in Spanish Universities in the Latter Half of the 16th Century
2006
The four universities known to have taught mathematics in the 16th century in what is now known as Spain, were Salamanca, Valencia, Alcala, and, at the end of the century, Seville. In addition to being taught at university, astronomy was also taught in other institutions such as for example, the Casa de la Contratacion of Seville, the so-called Mathematics Academy of Madrid, certain naval academies and, towards the end of the century, certain Jesuit schools. At the University of Valencia, following the official foundation of the Estudi or center of learning in 1500, a chair of mathematics was set up in 1503, although we have no documentary evidence of the subjects taught there in the early …
Reliģiozitātes un kauna saistība ar attieksmi pret seksualitāti
2019
Pētījuma mērķis bija noskaidrot, vai pastāv saistība starp reliģiozitāti, kaunu un attieksmēm pret seksualitāti. Pētījumā piedalījās 150 respondenti, vecumā no 18 līdz 55 gadiem, 45 vīrieši un 105 sievietes. Respondenti ir gan dažādu kristīgo konfesiju pārstāvji, gan arī cilvēki, kuri sevi uztver kā agnostiķus vai ateistus. Pētījuma datu ieguvei tika izmantota Kauna kompasa aptauja (Compass of Shame Scale, 2006), Seksuālā kauna aptauja (Kyle Inventory of Sexual Shame, 2013), Reliģisko saistību aptauja-10 (Religious Commitment Inventory-10, 2003) un Īsa seksuālo attieksmju aptauja (Brief Sexual Attitudes Scale, 2006). Pētījuma rezultāti uzrādīja statistiski nozīmīgu saistību starp reliģiozit…
