PREDGOVOR MULTIKONFERENCI
INFORMACIJSKA DRUŽBA 2021
Štiriindvajseta multikonferenca Informacijska družba je preživela probleme zaradi korone v 2020. Odziv se povečuje, v 2021 imamo enajst konferenc, a pravo upanje je za 2022, ko naj bi dovolj velika precepljenost končno omogočila normalno delovanje. Tudi v 2021 gre zahvala za skoraj normalno delovanje konference tistim predsednikom konferenc, ki so kljub prvi pandemiji modernega sveta pogumno obdržali visok strokovni nivo.
Stagnacija določenih aktivnosti v 2020 in 2021 pa skoraj v ničemer ni omejila neverjetne rasti IKTja, informacijske družbe, umetne inteligence in znanosti nasploh, ampak nasprotno – rast znanja, računalništva in umetne inteligence se nadaljuje z že kar običajno nesluteno hitrostjo. Po drugi strani se je pospešil razpad družbenih vrednot, zaupanje v znanost in razvoj. Se pa zavedanje večine ljudi, da je potrebno podpreti stroko, čedalje bolj krepi, kar je bistvena sprememba glede na 2020.
Letos smo v multikonferenco povezali enajst odličnih neodvisnih konferenc. Zajema okoli 170 večinoma spletnih predstavitev, povzetkov in referatov v okviru samostojnih konferenc in delavnic ter 400 obiskovalcev. Prireditev so spremljale okrogle mize in razprave ter posebni dogodki, kot je svečana podelitev nagrad – seveda večinoma preko spleta. Izbrani prispevki bodo izšli tudi v posebni številki revije Informatica (http://www.informatica.si/), ki se ponaša s 45-letno tradicijo odlične znanstvene revije.
Multikonferenco Informacijska družba 2021 sestavljajo naslednje samostojne konference:
• Slovenska konferenca o umetni inteligenci
• Odkrivanje znanja in podatkovna skladišča
• Kognitivna znanost
• Ljudje in okolje
• 50-letnica poučevanja računalništva v slovenskih srednjih šolah
• Delavnica projekta Batman
• Delavnica projekta Insieme Interreg
• Delavnica projekta Urbanite
• Študentska konferenca o računalniškem raziskovanju 2021
• Mednarodna konferenca o prenosu tehnologij
• Vzgoja in izobraževanje v informacijski družbi
Soorganizatorji in podporniki multikonference so različne raziskovalne institucije in združenja, med njimi ACM
Slovenija, SLAIS, DKZ in druga slovenska nacionalna akademija, Inženirska akademija Slovenije (IAS). V imenu organizatorjev konference se zahvaljujemo združenjem in institucijam, še posebej pa udeležencem za njihove dragocene prispevke in priložnost, da z nami delijo svoje izkušnje o informacijski družbi. Zahvaljujemo se tudi recenzentom za njihovo pomoč pri recenziranju.
S podelitvijo nagrad, še posebej z nagrado Michie-Turing, se avtonomna stroka s področja opredeli do najbolj izstopajočih dosežkov. Nagrado Michie-Turing za izjemen življenjski prispevek k razvoju in promociji informacijske družbe je prejel prof. dr. Jernej Kozak. Priznanje za dosežek leta pripada ekipi Odseka za inteligentne sisteme Instituta ''Jožef Stefan'' za osvojeno drugo mesto na tekmovanju XPrize Pandemic Response Challenge za iskanje najboljših ukrepov proti koroni. »Informacijsko limono« za najmanj primerno informacijsko potezo je prejela trditev, da je aplikacija za sledenje stikom problematična za zasebnost, »informacijsko jagodo« kot najboljšo potezo pa COVID-19 Sledilnik, tj. sistem za zbiranje podatkov o koroni. Čestitke nagrajencem!

FOREWORD - INFORMATION SOCIETY 2021
The 24th Information Society Multiconference survived the COVID-19 problems. In 2021, there are eleven conferences with a growing trend and real hopes that 2022 will be better due to successful vaccination. The multiconference survived due to the conference chairs who bravely decided to continue with their conferences despite the first pandemic in the modern era.
The COVID-19 pandemic did not decrease the growth of ICT, information society, artificial intelligence and science overall, quite on the contrary – the progress of computers, knowledge and artificial intelligence continued with the fascinating growth rate. However, COVID-19 did increase the downfall of societal norms, trust in science and progress. On the other hand, the awareness of the majority, that science and development are the only perspectives for a prosperous future, substantially grows.
The Multiconference is running parallel sessions with 170 presentations of scientific papers at eleven conferences, many round tables, workshops and award ceremonies, and 400 attendees. Selected papers will be published in the Informatica journal with its 45-years tradition of excellent research publishing.
The Information Society 2021 Multiconference consists of the following conferences:
• Slovenian Conference on Artificial Intelligence
• Data Mining and Data Warehouses
• Cognitive Science
• People and Environment
• 50-years of High-school Computer Education in Slovenia
• Batman Project Workshop
• Insieme Interreg Project Workshop
• URBANITE Project Workshop
• Student Computer Science Research Conference 2021
• International Conference of Transfer of Technologies
• Education in Information Society
The multiconference is co-organized and supported by several major research institutions and societies, among them ACM Slovenia, i.e. the Slovenian chapter of the ACM, SLAIS, DKZ and the second national academy, the Slovenian Engineering Academy. In the name of the conference organizers, we thank all the societies and institutions, and particularly all the participants for their valuable contribution and their interest in this event, and the reviewers for their thorough reviews.
The award for lifelong outstanding contributions is presented in memory of Donald Michie and Alan Turing. The Michie-Turing award was given to Prof. Dr. Jernej Kozak for his lifelong outstanding contribution to the development and promotion of the information society in our country. In addition, the yearly recognition for current achievements was awarded to the team from the Department of Intelligent systems, Jožef Stefan Institute for the second place at the XPrize Pandemic Response Challenge for proposing best counter-measures against COVID-19. The information lemon goes to the claim that the mobile application for tracking COVID-19 contacts will harm information privacy.
The information strawberry as the best information service last year went to COVID-19 Sledilnik, a program to regularly report all data related to COVID-19 in Slovenia. Congratulations!

While there is a substantial effort to detect, forecast and induce Implicitly, researchers treat change as dark matter: there is state change, especially in the mental health-related fields, the results of interest SA at a time t, state of interest SB at time t+1, and what have been mixed so far. Understanding what change is is happens in between is magic [1-4].1 When change is defined, therefore crucial. Data on first-person experience has been thus albeit rarely, it falls into reductionist pits, being reduced to far absent from studying change, which may turn out to be a neurobiological processes [5], or it is defined functionally, where deciding oversight.

DiaryE0:
Today I mostly felt quite inspired, determined and enthusiastic. I saw myself as important, I was very self-confident. This brought about a certain feeling, a certain change in the air around me. The air was pointing up, and I could move throughout differently. Also, for example, people listening to me at a seminar about using a tool for daily assessment had this directionality towards me which gave me some sort of power. Compared to yesterday, when I also felt inspired and enthusiastic, today I had this huge undertone of confidence, and this caused a difference especially in how I perceived others. Otherwise it was a full day, I had a meeting about the future of my software, I worked on my study, I sorted out the details of my stay in another country which I was invited to visit, to see the psychiatric processes and to share knowledge at their clinic, I had the before mentioned seminar, my girlfriend Jaya and I went together to a wonderful classical concert with my parents, and finally, we ate homemade apple pie and drank champagne that was a gift from my mom's best friend. It was a great day.

DiaryE1:
The day was signified by three moods - uninterested, determined, and inspired. I saw myself too scattered, without a center to hold me or to hold onto, and this made me uninterested in the world around me and it was hard to do anything I wanted to, which I disliked. The narrative of where I am was quite dispersed, and it was hard to look at the things that hold me together. At first I was frustrated, so I spend some time just embracing that feeling, with knowledge that afterwards I will pull myself together. When this phase came, I became determined to set myself straight, and I made a sort of a plan or a diagram of what I want to do and is important to me, what makes me happy. This was quite successful and afterwards I was inspired to do the tasks I wanted to do. The world was consequently also different, it is like after being inspired I am seeing it, it has this brighter quality, but not visually, but the feeling of its atmosphere. Otherwise I was quite happy to have my weekly meet with two of my friends online.

Issues with log-uniform distribution
In analysing the two models, we focused primarily on how dif-
ferent distributions affect the results. Due to the shape of log-uniform distribution (see Figure 2), the part of the graph that
is very close to zero has a significant impact on the final result.
Since we have a logarithmic scale, the part from zero to one on

Parameter importance
In order to analyse the stability/sensitivity of the two models, we studied which parameters have the greatest impact on the
final result. For this purpose, a dataset with different values and distributions for the parameters was created for the two models.
Then, three subsets were taken, each containing only the subset
with rows for which the probability that we survive at least
L years is above 90%. The L options chosen were: 1000, 10 000,
100 000. The importance of the features in each of the subsets was then calculated using the Gini importance method implemented
in the Python’s scikit-learn decision tree regressor algorithm [7].

for estimating probability of surviving 10 000 years.
We found that in the Sandberg model, parameters 2 and 9 play
the most important role, as you can see in Figures 6, 8 and 10,
which show the importance of the parameters in calculating the
probability that we survive 1000, 10 000 and 100 000 years.
In the model Rare Earth, on the other hand, parameters 5 and
7 are crucial for the prediction. This can be seen from Figures 5, 7
and 9, which show the importance scores of the parameters when calculating the same probabilities with the model Rare Earth.

DISCUSSION AND CONCLUSION
This research took two promising models from our earlier study
[4] and analysed stability and sensitivity of the models and parameters. We analysed the stability of the log-uniform distribution compared to the log-normal distribution. To determine the differ-Figure 8: Importance of parameters in Sandberg model for

5 MOŽNE IZBOLJŠAVE
Dejstvo, da je bil anketni vprašalnik večinoma reševan preko
spleta in ne v živo pa ima nekaj pomanjkljivosti. Testiranci so pri poslušanju zvočnih posnetkov violin imeli različno kakovostno
opremo (zvočniki). Testiranci z boljšo opremo so tako lahko bolj natančno slišali razlike v lastnostih zvoka med violinami. Nekaj 39

5 METHOD: PART 2
The second part of our research followed the approach used
by Douven (see [4] and the section on background above).
Particularly, we were interested in simulating an ICU with
doctors trying to diagnose their patients when the tests are
potentially unreliable/misleading. The situation is very
similar to part 1: instead of coin biases we deal with diseases
that may show some symptom with 0, .1, .2, ..., 1 probability
and tests that correspond to partial lying in various lying
styles: they are not fully reliable and our doctors estimate the reliability of the tests. We can then look at what the survival
rates were for each of the doctor's patients and replicate the
top performing half doctors and repeat this for 100
generations. Hence, we combine the research from the �irst
part and the research described in the background section.
Figure 2: Average percentage of agents ("simple" lying) 6 RESULTS: PART 2
The results are interesting: if we look at tests that are
constantly misleading (i.e., all of them are unreliable to some
degree that needs to be estimated) and if they correspond to
what would be akin to simple lying (if it is more likely that a
patient has a symptom X than not at the time of the testing,
the test will not show the presence of X), then the doctors
that infer to the best explanation prevail through generations
(see Figure 1 for an example of a simulation and Figure 2 for
average percentage of different doctors in our simulations).
However, if the tests correspond to being unreliable in what
is akin to gambler's or clairvoyant lying we get different
results: tests that are unreliable in the gambler's lying style
favor both Good's and explanationist reasoning (Figure 3),
while those that are like clairvoyant's (always the wrong
result) favor Bayes's rule: see Figure 4.

The ecological rationality of probabilistic learning rules in unreliable circumstances
Information Society 2021, 4–8 October 2021, Ljubljana, Slovenia
7 CONCLUSIONS
The results, especially those of Part 2, are very interesting
because they suggest that different probabilistic learning
rules that have been addressed in literature may be
preferable in different situations and preferable in various
environments. Ecological rationality then suggests that if we
happen to be in an environment with speci�ic features, which
we plan to identify in our future research work, then Bayes'
rule might be the best way to proceed. Similarly,
explanationist learning or Good's or Popper's learning might
be preferable in other situations. It remains an open question
what features of the information environment determine the
choice of a learning rule, but our results suggest that a
pluralist approach to learning rules under uncertainty is
needed. Our results also provide one possible explanation
why we seem to have different reasoning patterns under
uncertainty in a descriptive sense, that is, because different
environments call for different reasoning strategies. Further
research could also provide some insights into pluralist
reasoning strategies, i.e., strategy-switching.
