Exact Spectral Norm Regularization for Neural Networks

no code implementations27 Jun 2022 Anton Johansson, Claes Strannegård, Niklas Engsner, Petter Mostad

We pursue a line of research that seeks to regularize the spectral norm of the Jacobian of the input-output mapping for deep neural networks.

The Ecosystem Path to General AI

no code implementations17 Aug 2021 Claes Strannegård, Niklas Engsner, Pietro Ferrari, Hans Glimmerfors, Marcus Hilding Södergren, Tobias Karlsson, Birger Kleve, Victor Skoglund

Animal cognition is modeled by integrating three separate networks: (i) a reflex network for hard-wired reflexes; (ii) a happiness network that maps sensory data such as oxygen, water, energy, and smells, to a scalar happiness value; and (iii) a policy network for selecting actions.

Slope and generalization properties of neural networks

1 code implementation3 Jul 2021 Anton Johansson, Niklas Engsner, Claes Strannegård, Petter Mostad

From a statistical point of view, fitting a neural network may be seen as a kind of regression, where we seek a function from the input space to a space of classification probabilities that follows the "general" shape of the data, but avoids overfitting by avoiding memorization of individual data points.

Lifelong Learning Starting From Zero

no code implementations24 Jun 2019 Claes Strannegård, Herman Carlström, Niklas Engsner, Fredrik Mäkeläinen, Filip Slottner Seholm, Morteza Haghir Chehreghani

We present a deep neural-network model for lifelong learning inspired by several forms of neuroplasticity.
