Quanta produced a podcast to explain our research (published by the Royal Society) on the emergence of units like genes through algorithmic evolution
(under the most self-evident assumption that evolution is not a random ergodic process but is constrained to regions removed from randomness in a rule-driven space). |
I was invited to write an essay to imagine Computing in the Year 2065--Springer edited by Prof. A. Adamatzky--of which a first draft can be read Reprogramming Matter, Life, and Purpose.

I consider myself a 'computational natural scientist', Greg Chaitin, one of the founders of the fundamental area of Algorithmic Information Theory, described me as a "new kind of practical theoretician". With the help of a team of brilliant colleagues, I led and introduced the field of Algorithmic Information Dynamics (AID).
I currently work on the foundations of symbolic computation in machine intelligence. The goal is to equip some approaches to machine learning with an inference engine to deal with causal discovery (and causal analysis), and model generation; mostly in the context of molecular biology, immunology, and oncology. Previously, I was a Research Associate at the Behavioural and Evolutionary Theory Lab at the Department of Computer Science at the University of Sheffield in the UK before joining the structural biology group at the Department of Computer Science at the University of Oxford as a Senior Researcher (faculty member), and then director of Oxford Immune Algorithmics. I co-lead the Algorithmic Dynamics Lab at the Karolinska Institute (the institution that awards the Nobel Prize in Medicine or Physiology) where I team up with experimental scientists such as molecular biologists, immunologists, oncologists, toxicologists, and other mathematicians to understand and study first principles of living systems. I lead the Algorithmic Nature Group, the lab that started the Online Algorithmic Complexity Calculator and the Human Randomness Perception and Generation Project (triggering wide media coverage), a kind of inverse Turing test involving almost 3,400 human minds. I am also the managing Editor of Complex Systems, the first journal in the field of complexity science founded by Stephen Wolfram in 1987, and member of the editorial boards of several journals and book series. I have served in evaluation committees for grants and awards for institutions in the U.S. (the Simon Foundation and the NIH), Canada (Banff International Research Station), Europe (FP7, H2020, FET, RIA) and other national funding agencies in Poland, Chili, and Mexico. |

One year before passing away, Marvin Minsky, widely considered the founding father of Artificial Intelligence, made an astonishing claim describing what turns out to be exactly my research aim and purpose in a closing statement at a prime venue (video on the right):
"It seems to me that the most important discovery since Gödel was the discovery by Chaitin, Solomonoff and Kolmogorov of the concept called Algorithmic Probability which is a fundamental new theory of how to make predictions given a collection of experiences and this is a beautiful theory, everybody should learn it, but it’s got one problem, that is, that you cannot actually calculate what this theory predicts because it is too hard, it requires an infinite amount of work. However, it should be possible to make practical approximations to the Chaitin, Kolmogorov, Solomonoff theory that would make better predictions than anything we have today. Everybody should learn all about that and spend the rest of their lives working on it."

On the other hand, these excerpts from a review article by Sydney Brenner — the 2002 Nobel prize in Physiology or Medicine laureate awarded by the Karolinska Institute -- completes the picture of what I and my lab at the Karolinska Institute strive:
"[on biological research] in Alan Turing’s work there is much to guide us
. . . Although many believe that ‘more is better’, history tells us that ‘least is best’. We need theory and a firm grasp on the nature of the objects we study to predict the rest . . . The concept of the gene as a symbolic representation of the organism — a code script — is a fundamental feature of the living world and must form the kernel of biological theory."

"AI is currently split. First, there are those who are intoxicated by the success of machine learning and deep learning and neural nets. They don’t understand what I’m talking about. They want to continue to fit curves. But when you talk to people who have done any work in AI outside statistical learning, they get it immediately. I have read several papers written in the past two months about the limitations of machine learning."
Interviewer: The way you talk about curve fitting, it sounds like you’re not very impressed with machine learning. "No, I’m very impressed, because we did not expect that so many problems could be solved by pure curve fitting. It turns out they can. But I’m asking about the future — what next? Can you have a robot scientist that would plan an experiment and find new answers to pending scientific questions? That’s the next step. We also want to conduct some communication with a machine that is meaningful ... |
One of my research aims is to reintroduce symbolic computation into statistical machine learning to alleviate current limitations in techniques such as deep learning along the lines of the criticisms put forward by people such as Sydney Brenner, Marvin Minsky and Judea Pearl and believed to be fundamental to make further progress in AI research. Here a video produced by the journal Nature to explain my research:

I got interested in neural networks from the standpoint of computability and complexity theory in my early 20s when writing my final year memoir for my BSc in math degree at UNAM. Today I am trying to help revolutionise the area by reintroducing the theories of computability and algorithmic randomness back into the field of neural networks, in particular, to machine and deep learning.
On the right is an image showing how a deep neural network trained with a large set of fine art paintings 'sees' me. My current research consists in helping machine and deep learning see beyond statistical patterns in more clever ways than simple pattern matching. By introducing algorithmic probability to artificial intelligence we aim at helping traditional deep learning to incorporate more abstract thinking of the type needed to understand the basic concept of cause and effect. Known to underperform in tasks requiring abstraction and logical inference, current approaches to deep neural networks are very limited. An example of our research in this direction is our paper published in Nature Machine Intelligence that can be read here for free (no paywall). |

As reported in our paper published in the journal of Cellular Automata (also available in the arXiv), by exhaustive exploration of rule composition, two 4-colour cellular automata that we've proved to be Turing universal.
This means that these CAs can, in principle, run MS Windows and any other software. These new CAs helped us show how the Boolean composition of two and three ECA rules can emulate rule 110. This also means that these new CAs can be decomposed into simpler rules and thus illustrates the process of causal composition and decomposition. It also constitutes a form of sophisticated causal coarse-graining that I have explored in other papers such as this one. In the same paper we also introduced a minimal set of ECA rules that can generate all others by Boolean composition. |
These CAs that we have proven to be Turing-universal using novel methods, and thus are able to run any computable function are the result of combining the power of extremely simple computer programs (ECAs):
Composition of ECA rules 50 ◦ 37 with colour remapping leading to a 4-colour Turing universal CA emulating rule 110.
Composition of ECA rules 170 ◦ 15 ◦ 118 with colour re-mapping mapping leading to a 4-colour Turing universal CA emulating rule 110.

A new kind of research-based cryptocurrency:
My students and I are developing a new more responsible and eco-friendly cryptocurrency to help science reveal models of the world. We are creating and developing the first coin whose purpose is to perform the most meaningful computation (all possible useful computations). It provides a sense and meaning to crypto-mining and, in a sense, is thus the most eco-friendly coin possible as every computation involved contributes to a specific scientific calculation. It aims at using crypto-mining as a force for research rather than wasting precious resources, it will implement incremental lossless compression too. It is also the first coin purely based on the most basic computational principles that are behind all other cryptocurrencies but in a purely transparent fashion. Click on the banner to see the new website of the project. AUTOMATA 2020 is the first conference that will accept Automacoins as partial payment for conference fees.
