  • Reproducibility problems of artificial intelligence inherently come from random numbers

    Matthew Hutson wrote an article entitled “Has artificial intelligence become alchemy?” (1). Matthew only focused on deep learning as artificial intelligence. There are two kinds of artificial intelligence: deductive reasoning and inductive reasoning. Deep learning is classified into inductive reasoning, stochastic reasoning, or statistical reasoning. Since stochastic (statistical) reasoning schemes are all based on random numbers, generating random numbers are to change the result of deep learning. Deductive reasoning schemes do not use random numbers so that the reproducibility problem does not exist. Many of artificial intelligence researchers are not aware of the importance of a random number seed. Before running an artificial intelligence (deep learning) program, the random number seed should be fixed. Without fixing the random number seed, the result may be changed. In other words, the reproducibility problems of the artificial intelligence (deep learning) can be fixed.

  • Advancing Artificial Intelligence

    The characterization of artificial intelligence (AI) as alchemy, albeit emotive, is merely an acknowledgment of the lack of understanding of the workings of the underlying algorithms (1, see also 2). In developing an explicit theoretical understanding of intelligence, following in the footsteps of physics makes perfect sense. However, the toy problem (black-and-white images instead of color photos) prescribed for gaining insights into recognition algorithms appears to be diagnostic of a deeper problem with contemporary AI, which is getting lost in the here & now of immediate solutions and losing sight of the big picture: development of the science of intelligence (3). Here we suggest a different approach: mathematical knowing as a Bohr atom of knowing, which can serve as a solid foundation to build the science of human intelligence (subsuming reasoning, perception, and cognition, among others).

    But how, and why?

    First, science is a hallmark of human intelligence. As such, a scientific account of science constitutes the science of intelligence. Although we do not have the science of the development of scientific theories and models, we have functorial semantics: a mathematical account of abstracting theories and building models of various categories of mathematical objects (4, 5). Taking a cue from Galileo's investigation of a simple motion—motion of falling bodies—that served as a foundation for the science of motion, we suggest investigating t...
