Andrzej Cichocki (born 1947) is a Polish computer scientist, electrical engineer and a professor at the Systems Research Institute of Polish Academy of Science, Warsaw, Poland and a visiting professor in several universities and research institutes, especially Riken AIP, Japan. He is most noted for his learning algorithms for   Signal separation (BSS), Independent Component Analysis (ICA), Non-negative matrix factorization (NMF), tensor decomposition,     Deep (Multilayer) Matrix Factorizations for ICA, NMF, PCA,  neural networks for optimization and signal processing, Tensor  network  for Machine Learning and Big Data, and brain–computer interfaces. He is the author of several monographs/books [1] and more than 500 scientific peer-reviewed articles.[2]

Education and Career

Andrzej Cichocki in 2013 in Riken Brain Science Institute

Andrzej Cichocki received his M.Sc. (with honors), PhD and doctor of science (Dr.Sc.- Habilitation) degrees all in electrical engineering and computer science from the Warsaw University of Technology, Poland.

He received the title of full Professor in 1995.

From 1984 to 1989 he was a Alexander von Humboldt Research Fellow and DFG visiting scholar at the University of Erlangen Nurnberg, Germany and he worked closely with Professor Rolf Unbehauen.

From 1996 till 2018 he worked in RIKEN Brain Science Institute, Wako-shi, Japan at Shun'ichi Amari's Research Department, as a team leader and later as senior head of laboratories. He established and ran in RIKEN BSI three laboratories: Open Information Systems, Artificial Brains Systems and Cichocki's Laboratory for Advanced Brain Signal Processing.

In 2018-2022 he holds a distinguished visiting professorship at several universities including Hangzhou Dianzi University in Hangzhou, China and Tokyo University of Agriculture and Technology (TUAT), Tokyo, Japan.

Research

He is one of the leading computer scientists affiliated with Poland.[3]

Andrzej Cichocki has contributed extensively to several major interests of signal/image processing, machine learning and AI, including Independent Component Analysis (ICA), Non-negative matrix factorization (NMF) and artificial neural networks. He developed an efficient Hierarchical Alternating Least Squares (HALS) algorithm.[4][5]

He pioneered developing and applying new beta and alpha-beta and other divergences in machine learning, especially for non-negative matrix factorizations and nonnegative tensor decompositions. Moreover, he pioneered in development of multilayer (deep) matrix and tensor factorization models and learning algorithms, especially for ICA, NMF and Sparse Component Analysis (SCA).[6][7][8] He developed and proposed new recurrent neural network architectures for optimization, solving large scale systems of algebraic equations and blind signal separation, especially multilayer (deep) hierarchical neural networks. He contributed to development of natural gradient algorithms for Independent Component Analysis (ICA) and blind deconvolution.[9][10]

He proposed together with his co-workers several efficient AI models and machine learning algorithms for brain computer interface, human emotions recognition and early diagnosis of some brain diseases, like Alzheimer and Schizophrenia.

Following concerns raised by some  AI experts about the potential risks that  AGI  may pose  on humanity, Cichocki  suggested   in 2021 development of novel   AGI  systems  with implemented multiple intelligences, including  not only ethical/moral  intelligence but also social-emotional intelligence with self-awareness and responsible decision making abilities.

His current research interests include:

  • Tensor decomposition and tensor networks
  • Learning of non-stationarity data
  • Data fusion of multi-modal structured data, and deep neural networks compression
  • Applications: EEG, NIRS, ECoG, EMG, Brain Computer Interfaces, computational neuroscience, computer vision.
  • Time series forecasting and analysis
  • Online portfolio selection (OLPS)
  • Exponentiated gradient and natural gradient learning algorithms for various applications
  • Artificial General Intelligence (AGI) with multiple intelligences
