Title: From continuous biosignals to spike trains: LAST opens the door to the effective training of spiking neural networks on continuous signals

Abstract: 

Can we use the brain’s own language to diagnose chronic lower back pain? In this talk, I’ll present our groundbreaking work applying Spiking Neural Networks (SNNs) to classify chronic lower back pain using the EmoPain dataset. This is the first time SNNs have been used for this purpose.

We’ve developed a novel encoding technique called Learning Adaptive Spike Thresholds (LAST) to efficiently convert continuous biosignals into spike trains. Combined with an ensemble of Spiking Recurrent Neural Networks (SRNNs), our approach effectively handles the complexities of multi-stream sEMG and IMU data.

Despite the challenges of limited data and imbalanced classes, we’ve achieved impressive results, outperforming traditional methods and even state-of-the-art deep learning models. Our findings pave the way for energy-efficient, wearable solutions for chronic pain management. Join me to learn more about our innovative approach and its potential impact.

He is currently pursuing additional studies at the Australian National University (ANU) in Canberra, Australia. His research interests span efficient neuromorphic computing, particularly Spiking Neural Networks (SNNs), Computer Vision, and Natural Language Processing (NLP).

His Master’s thesis focused on developing energy and time-efficient AI models using SNNs, resulting in a cum laude distinction and a forthcoming journal publication. To broaden his AI expertise, he is exploring Computer Vision at ANU. Additionally, Freek gained experience in NLP during an internship centred on large-scale text classification with limited labelled data.

Title: A journey to re-embodiment

Abstract:

In this presentation, I will discuss my past, highlighting the relevant experiences and projects that have brought me here today. I will go into parts of my portfolio that showcase my abilities, as well as my thought process and general interests, both historically and moving forward. This will hopefully give you a good picture of what you can expect from me and how I can be helpful in the future.

Speaker: Miguel A. Vadillo, Associate Professor at Universidad Autónoma de Madrid, Director of the Cognition, Attention, and Learning Lab (CALL)

Title: Seeing (a pre-registered protocol) is believing

Abstract: 
How much confidence should you put on a particular hypothesis if p < .05? From a rational point of view, the credibility of a scientific finding depends on three parameters: a) the prior likelihood of the hypothesis being true, b) the probability of a significant result if the alternative hypothesis is true, and c) the probability of a significant result if the null hypothesis is true. Unfortunately, (a) is largely subjective. (b) and (c) cannot be properly estimated with the information typically reported in scientific papers, but meta-scientific studies suggest that there are reasons to be pessimistic. Psychological research is often underpowered, which means that (b) is too low, and everything suggests that many significant findings could be the result of questionable research practices, casting doubt on (c). When we read a non-registered study, we can never know if the result is reliable or if the data were simply “tortured until they confessed”. The crucial contribution of pre-registration is that it ensures that the false positive rate is not inflated by questionable research practices or selective reporting. Furthermore, pre-registration forces researchers to plan their sample size based on a formal power analysis, ensuring that (b) is sufficiently large. As a result, in this talk I will defend that it is logical to put more faith in pre-registered studies than in non-registered research. Although non-registered research is not without value, pre-registration is definitely worthwhile.

Biography:
Miguel Vadillo is associate professor at Universidad Autónoma de Madrid, where he coordinates the Cognition, Attention, and Learning Lab (CALL). He is also the current president of the Spanish Society for Experimental Psychology, member of the ethical review board at UAM, and member of the scientific committee of the National Research Agency. His research is focused on statistical problems in research on implicit learning and other unconscious mental processes and also on meta-analytic methods for the detection of biases in scientific research.

Speaker: Yeseul Song, Assistant Arts Professor at NYU ITP/IMA (New York University Tisch School of the Arts’ Interactive Telecommunications Program / Interactive Media Arts)

Title: Feeling and Perceiving with New Sensory Languages

Abstract:
Can you trust something that you can’t see? When an object does not have a form but is perceivable, does that object “exist”? How can we collectively perceive something that exists in-between our bodies?

The current technoculture relies heavily on vision, and the dominance has become even stronger with the advent of screen-based digital technologies. On the other hand, our vision is limited—sighted humans can only see a sliver of the whole electromagnetic spectrum (wavelengths from about 390 to 700 nm) and most of the waves around us including radio waves, microwaves, X-rays, and “energy” are completely invisible to the human eye. What are we missing when seeing becomes our foremost sense in how we are perceiving the world

Since 2018, Yeseul Song has been studying the negative space of visual senses and creating artistic non-visual sensory languages that are imaginative and accessible. Based on her research on technology and perception, she has created interactive artwork that inspired people from all over the world. To name a couple, Invisible Sculptures (2018-2021) is a series of sculptures that can be “seen” through senses other than vision. Two Subtle Bodies (2022) is an interactive auditory experience where two strangers experience each other’s peripersonal space through the sound. In this talk, she will share her artistic research in hybrid and alternative ways of feeling and perceiving.

Speaker: Pablo Zamorano, Independent Artist/Researcher

Title: Workshop/Seminar Which words arise from the body as it moves?

Abstract: 

What part of my existence makes up the body I have; Merleau Ponty said in his phenomenology of perception: “I am my body”, removing any idea of mind/body duality from his discourse. But if I am my body, how can I understand that which I myself am?

Through our body and our contact with those around us, we create a particular interpretation of the world, but also of ourselves. Society teaches us how to cognitively perceive ourselves, but it also subjects the sphere of emotions and feelings to a process of subjectivization in this exercise of recognition. So what we feel is also a reflection of a social codification.
