### Conference Scope

Swarm intelligence is the discipline that deals with the study of self-organizing processes both in nature and in artificial systems. Researchers in ethology and animal behavior have proposed a number of models to explain interesting aspects of collective behaviors such as movement coordination, shape-formation or decision making. Recently, algorithms and methods inspired by these models have been proposed to solve difficult problems in many domains. ANTS 2022 will give researchers in swarm intelligence the opportunity to meet, to present their latest research, and to discuss current developments and applications.

### Relevant Research Areas

ANTS 2022 solicits contributions dealing with any aspect of swarm intelligence. Typical, but not exclusive, topics of interest are:
• Behavioral models of social insects or other animal societies that can stimulate new algorithmic approaches.
• Empirical and theoretical research in swarm intelligence.
• Application of swarm intelligence methods, such as ant colony optimization or particle swarm optimization, to real-world problems.
• Theoretical and experimental research in swarm robotics systems.

#### The 5 most popular artificial neural networks

Abstract: Modern Artificial Intelligence is dominated by artificial neural networks (NNs) and deep learning. I am proud that foundations of the most popular NNs originated in my labs. Here I discuss: (1) Long Short-Term Memory (LSTM), the most cited NN of the 20th century, (2) ResNet, the most cited NN of the 21st century (an open-gated version of our Highway Net: the first working really deep feedforward NN), (3) AlexNet and VGG Net, the 2nd and 3rd most frequently cited NNs of the 21st century (both building on our similar earlier DanNet: the first deep convolutional NN to win image recognition competitions), (4) Generative Adversarial Networks (an instance of my earlier Adversarial Artificial Curiosity), and (5) variants of Transformers (Transformers with linearized self-attention are formally equivalent to my earlier Fast Weight Programmers). Most of this started with our Annus Mirabilis of 1990-1991 when compute was a million times more expensive than today. In the 2010s, all of this work was feverishly built on by an outstanding community of machine learning researchers, engineers, and practitioners to create amazing things that have impacted the lives of billions of people worldwide.

Bio: Since age 15 or so, the main goal of professorJürgen Schmidhuber has been to build a self-improving Artificial Intelligence (AI) smarter than himself, then retire. He is often called the "father of modern AI" by the media. His lab's Deep Learning Neural Networks (NNs) based on ideas published in the "Annus Mirabilis" 1990-1991 have revolutionised machine learning and AI. In 2009, the CTC-trained Long Short-Term Memory (LSTM) of his team was the first recurrent NN to win international pattern recognition competitions. In 2010, his lab's fast and deep feedforward NNs on GPUs greatly outperformed previous methods, without using any unsupervised pre-training, a popular deep learning strategy that he pioneered in 1991. In 2011, the DanNet of his team was the first feedforward NN to win computer vision contests, achieving superhuman performance. In 2012, they had the first deep NN to win a medical imaging contest (on cancer detection). This deep learning revolution quickly spread from Europe to North America and Asia, and attracted enormous interest from industry. By the mid 2010s, his lab's NNs were on 3 billion devices, and used billions of times per day through users of the world's most valuable public companies, e.g., for greatly improved speech recognition on all Android smartphones, greatly improved machine translation through Google Translate and Facebook (over 4 billion LSTM-based translations per day), Apple's Siri and Quicktype on all iPhones, the answers of Amazon's Alexa, and numerous other applications. In May 2015, his team published the Highway Net, the first working really deep feedforward NN with hundreds of layers—its open-gated version called ResNet (Dec 2015) has become the most cited NN of the 21st century, LSTM the most cited NN of the 20th (Bloomberg called LSTM the arguably most commercial AI achievement). His lab's NNs are now heavily used in healthcare and medicine, helping to make human lives longer and healthier. His research group also established the fields of mathematically rigorous universal AI and recursive self-improvement in metalearning machines that learn to learn (since 1987). In 1990, he introduced unsupervised generative adversarial neural networks that fight each other in a minimax game to implement artificial curiosity (the famous GANs are instances thereof). In 1991, he introduced neural fast weight programmers formally equivalent to what's now called Transformers with linearized self-attention (Transformers are popular in natural language processing and many other fields). His formal theory of creativity & curiosity & fun explains art, science, music, and humor. He also generalized algorithmic information theory and the many-worlds theory of physics, and introduced the concept of Low-Complexity Art, the information age's extreme form of minimal art. He is recipient of numerous awards, author of about 400 peer-reviewed papers, and co-founder and Chief Scientist of the company NNAISENSE, which aims at building the first practical general purpose AI. He is a frequent keynote speaker, and advising various governments on AI strategies.

Professor of Computer Engineering, Polytechnique Montreal

#### Swarm Robotics Across Scales: Engineering Complex Behaviors

Abstract: Swarm robotics relies on many simple robots, governed by local interactions to implement complex behaviours, generally inspired by biological systems. What are the ingredients necessary for the of design artificial swarms for practical applications? This talk will present some of the challenges of practical swarms, identifying in particular the limitations of a leaderless hierarchy, where robots have only a partial view of their mission, as well as ways to circumvent these limitations by exploiting heterogeneous swarms. This talk will use several practical examples, including the control of smart materials, search and rescue missions, and space exploration.

Bio: Giovanni Beltrame obtained his Ph.D. in Computer Engineering from Politecnico di Milano, in 2006 after which he worked as microelectronics engineer at the European Space Agency on a number of projects spanning from radiation-tolerant systems to computer-aided design. In 2010 he moved to Montreal, Canada where he is currently Professor at Polytechnique Montreal with the Computer and Software Engineering Department. Dr. Beltrame directs the MIST Lab, with more than 20 students and postdocs under his supervision. He has completed several projects in collaboration with industry and government agencies in the area of robotics, disaster response, and space exploration. His research interests include modeling and design of embedded systems, artificial intelligence, and robotics, on which he has published research in top journals and conferences.

#### Mexican Waves: The Adaptive Value of Collective Behaviour

Abstract: The collective behaviour of animals has attracted considerable attention in recent years, with many studies exploring how local interactions between individuals can give rise to global group properties. The functional aspects of collective behaviour are less well studied, especially in the field and relatively few studies have investigated the adaptive benefits of collective behaviour in situations where prey are attacked by predators. This paucity of studies is unsurprising because predator-prey interactions in the field are difficult to observe. Furthermore, the focus in recent studies on predator-prey interactions has been on the collective behaviour of the prey rather than on the behaviour of the predator. Here I present a field study that investigated the antipredator benefits of waves produced by fish at the water surface when diving down collectively in response to attacks of avian predators. Fish engaged in surface waves that were highly conspicuous, repetitive, and rhythmic involving many thousands of individuals for up to 2 min. Collective fish waves increased the time birds waited until their next attack and also reduced capture probability in three avian predators that greatly differed in size, appearance and hunting strategy. Taken together, these results support a generic antipredator function of fish waves which could be a result of a confusion effect or a consequence of waves acting as a perception advertisement, which requires further exploration.

Bio: Jens Krause is a behavioural ecologist with a strong interest in collective behaviour and social networks. He has published a number of books (Living in Groups, OUP; Fish Cognition and Behavior, Wiley/Blackwells; Exploring Animal Social Networks, PUP; Animal Social Networks, OUP) and articles on the mechanisms and functions of living in groups. He is currently professor for fish biology and ecology in the Faculty of Life Science at the Humboldt University Berlin, Head of Department at the Leibniz-Institute of Freshwater Ecology and Inland Fisheries and on the executive board of the excellence cluster “Science of intelligence”. He started his university education at the Free University Berlin and obtained his PhD from St. John’s College Cambridge, UK, followed by postdocs at Mount Allison University, Canada, and Princeton University, USA, and held a professorship for behavioural ecology at Leeds University, UK, for several years before moving back to Berlin in 2009. In 2014 he was elected into the Berlin-Brandenburgische Akademie der Wissenschaften.

Deadline for submission: June 29, 2022

### Formatting instructions

Papers must be prepared in the LNCS Springer LaTeX style, using the default font and font size. Authors should consult Springer’s authors’ guidelines and use their proceedings template for LaTeX, for the preparation of their papers. Please download the LNCS Springer LaTeX template package (zip, 302 kB) and authors' guidelines (pdf, 192 kB) directly from the Springer website. The LaTeX class and references style (llncs.cls and splncs04.bst) included in this package should not be modified. Please also download and consult the ANTS 2022 sample LaTeX document (zip, 129 kB), which shows the correct options to use within the Springer template.

Your submission should be uploaded as a compressed archive (zip, tgz), containing the final camera-ready versions of the following:

• the compiled PDF (pdf),
• the main LaTeX file (tex),
• the references file (both in bib and bbl),
• and all figures, where applicable (pdf, eps, png, jpeg, tiff, bmp).

Figures should be in their original vector format (pdf, eps), if applicable. Otherwise, figures provided in raster format (png, jpeg, tiff, bmp) must be high-resolution (if including linework, at least 800 dpi at the final size, otherwise, at least 300 dpi at the final size).

Although figures in the digital proceedings will be in full color, the print proceedings of ANTS 2022 will be printed in grayscale. Authors should therefore ensure that their figures will be appropriately legible when printed in grayscale.

Springer encourages authors to include their ORCIDs in their papers. In addition, the corresponding author of each paper, acting on behalf of all of the authors of that paper, must complete and sign a Consent-to-Publish form. The corresponding author signing the copyright form should match the corresponding author marked on the paper. Once the files have been sent to Springer, changes relating to the authorship of the papers cannot be made.

#### Number of pages

Full-length Papers are strictly limited to 11 pages + references, and Short Papers are strictly limited to 7 pages + references.

These page limits include figures, tables, and all supplementary sections (e.g., Acknowledgements). The only exclusion from these page limits is the reference list, which should have an appropriate length with respect to the state of the art.

Extended Abstracts are strictly limited to 2 pages (including references).

All page limits refer to papers prepared in the LNCS Springer LaTeX template, according to the instructions provided here. Do not modify the template defaults, such as those for margins, line spacing, or font size.

#### Using the LNCS Springer LaTeX style

Submissions must be prepared in LaTeX, and the source files (tex, bib, bbl) must be provided. Authors should use the LaTeX class and references style files (llncs.cls and splncs04.bst) as provided in the LNCS Springer LaTeX template package. These files should not be modified. Also, do not add formatting modifications to the main document (tex) to override the template defaults. Do not use, for instance, any line spacing modifications (e.g., \vspace{} or \\*[0pt]), or font size modifications (e.g., \fontsize{}). Please do not add any special fonts. Please do not add packages or custom commands that change the formatting (e.g., do not use the package subcaption, as it overrides the default caption formatting in the template).

During the final preparation of the proceedings, any formatting modifications in the main document (tex) will be removed if they do not match the template, potentially causing a change in paper length. Springer will also recompile all papers using their original llncs class file (llncs.cls). If authors make any modifications to the llncs file, their paper will not compile correctly in the final step, and cannot be included in the proceedings.

References must be formatted using the provided references style file (splncs04.bst). In this references style, in-text citations will appear as numbers, and the numbered reference list will be ordered alphabetically.

For further information, please refer to the class documentation included in the LNCS Springer LaTex package, and to the LNCS Springer authors’ guidelines.

#### ANTS 2022 formatting details

It is mandatory that submissions to ANTS 2022 follow certain options within the LNCS Springer template. The ANTS 2022 sample LaTeX document (zip) shows the correct template options to use. These mandatory template options are as follows.

• The running header option should be activated. This is activated by starting your LaTeX document (tex) with the command: \documentclass[runningheads]{llncs}.
• In the author-running field: \authorrunning{}, give the initial of the first name(s) and the full surname. Always give the first author's name. If there are precisely two authors, then give both the first and second authors' names. If there are more than two authors, use ‘et al.’ after the name of the first author.
• If the title is too long for the header, specify a shorter header title using the title-running field: \titlerunning{Abbreviated paper title}.

• The title, headings, and subheadings should be capitalized according to standard ‘Title Case’ style (i.e., all words should be capitalized, except for articles, prepositions, and conjunctions).
• Do not use a \newline command with the title.

Author names and affiliations:

• Follow the naming convention in which the surname is the last name.
• Using the LaTex \author{} field, provide the full first name (not only the initial).
• Do not include academic titles (e.g., Prof. or Dr.).
• Springer encourages the inclusion of author ORCIDs. These can be optionally included using the LaTex field \orcidID{} within the LaTex field \author{}.
• Author affiliation information should include the following, using the \institute{} and \email{} fields: department, faculty, university, company (if applicable), city, country, and email address. Do not include the street address or ZIP code (it is not a postal address). The email address of the corresponding author is mandatory to include in the \institute{} and \email{} fields.
• After the \institute{} entries, include an \index{} entry for each author, giving the full surname, followed by the full first name(s).

For further details, please refer to the documentation of the llncs class.

Acknowledgements:

• Acknowledgements, if any, should be given as the last subsubsection of the paper, just before the list of references.
• Do not format acknowledgments as a footnote, anywhere in the paper.

Keywords:

• Do not include keywords in your manuscript; they will not be included in the proceedings.

For contributions accepted as Extended Abstracts:

• Extended Abstract submissions must not contain an abstract, and must not include any section headings (or subheadings) in the main body. (Other than the title, the only headings in the manuscript should be for the References and Acknowledgments, if applicable).
