Early results from studies of the asymmetric Hopfield Model
The initial behavior of the asymmetric Hopfield model during training is investigated. It is shown that the distribution of the eigenvalues of the system in the complex plane initially falls within the unit circle that characterizes a completely random state. This finding suggests that the system is still in a highly uncertain state during the initial stages.
As the training progresses, some eigenvalues begin to separate from the unit circle, indicating that the system gradually stores information and forms a non-equilibrium structure. This phenomenon means that the system deviates from the thermodynamically stable state and exhibits more complex behavior. It can be seen that the in-depth development of neural networks and artificial intelligence may require the intersection of multiple disciplines, including equilibrium statistical physics, non-equilibrium statistical physics, nonlinear dynamics, and information theory.
Interdisciplinary and complex systems research
Current machine learning techniques, especially large language models, still operate within the framework of classical physics, reflecting the classic phenomenon of "more is different". This classic phenomenon refers to the difference between overall behavior and individual behavior when the scale of the system increases. Therefore, researchers need to consider how to introduce the principles of quantum physics into this field to promote deeper development.
Potential Impacts of Quantum Physics
The actual introduction of quantum physics may change our understanding of information processing and storage. The properties of quantum computing, such as superposition and entanglement, can provide new perspectives and methods for the efficiency and power of neural networks and artificial intelligence. This transformation may lead to the birth of new algorithms and models, further improving the processing power of complex systems.
By integrating knowledge from these disciplines, we may be able to more fully understand the dynamic behavior of complex systems and achieve greater breakthroughs in the research of artificial intelligence and machine learning. It is expected that future research will place greater emphasis on interdisciplinary collaboration and comprehensive exploration within the framework of complex systems.
2024 Nobel Prize in Chemistry
On October 9, 2024, the Royal Swedish Academy of Sciences announced the 2024 Nobel Prize in Chemistry in recognition of groundbreaking advances in protein science. This year's awards are divided into two parts:
The three winners are:
David Baker
Washington University
Howard Hughes Medical Institute
Award reason: Computational protein design
Demis Hassabis
Google Deep Mind London, UK
John M. Jumper
Google Deep Mind London, UK
Reason for the award: Protein structure prediction
Scientific background
This year's Chemistry Prize focuses on proteins, the chemical tools of life that play a vital role in living organisms. David Baker succeeded in designing an entirely new type of protein, an unprecedented feat, while Demis Hassabis and Johann Gamper developed an artificial intelligence model that solved a 50-year-old problem: predicting the complex structures of proteins.
Proteins are the basis of life; they control and drive all chemical reactions and serve as the building blocks of hormones, signaling substances, antibodies, and different tissues. These award-winning discoveries not only demonstrate the diversity of proteins, but also reveal their amazing capabilities as chemical tools.
Importance of discovery
David Baker's research achievements include designing new proteins using 20 different amino acids. His research group has created many novel proteins since 2003, including proteins used as drugs, vaccines, nanomaterials and microsensors.
On the other hand, Demis Hassabis and John Gamper's AI model AlphaFold2 marks a major breakthrough in protein structure prediction. Since 2020, this model has helped researchers predict the structures of almost all 200 million known proteins. AlphaFold2 has a wide range of applications, helping scientists better understand antibiotic resistance and create images of enzymes that can break down plastic.
Proteins are the basis of life, and now we can predict the structure of proteins and design our own proteins, which is of great benefit to humanity. These award-winning discoveries not only have far-reaching significance in scientific research, but also open new doors for future biomedical and biotechnology applications.
