This study introduces a novel method for statistical learning, enabling efficient pattern discovery. It addresses the complexity of generative models by optimizing a lower bound, facilitating hierarchical self-supervised learning.

Area of Science:

  • Statistical inference and machine learning
  • Computational neuroscience

Background:

  • Discovering inherent structure in patterns is key to statistical inference and learning.
  • Parameterized stochastic generative models are useful but computationally challenging due to combinatorial explosion.

Purpose of the Study:

  • To develop a method for efficiently inferring structure from patterns using generative models.
  • To overcome the intractability of parameter optimization in complex generative models.

Main Methods:

  • Maximizing an easily computed lower bound on the probability of observed patterns.
  • Developing a technique to finesse the combinatorial explosion in generative model parameter adjustment.

Main Results:

  • The proposed method allows for tractable optimization of generative models.
