Similarity and Matching of Neural Network Representations

Publication
December 6, 2021
publications
We employ a toolset — dubbed Dr. Frankenstein — to analyse the similarity of representations in deep neural networks. With this toolset we aim to match the activations on given layers of two trained neural networks by joining them with a stitching layer. We demonstrate that the inner representations emerging in deep convolutional neural networks with the same architecture but different initialisations can be matched with a surprisingly high degree of accuracy even with a single, affine stitching layer.

Development of a Real-Time, Autonomous Energy Information and Production Management System

Grant
October 1, 2021
grants
December 7, 2021 - Project Launch Press Release The energy industry has undergone significant changes over the past decade. The main drivers of these changes have been the strengthening of climate awareness, the importance of energy supply security, and the intertwining and connecting development of information technology across industries. The world of energy production is gradually shifting from traditional, centralized, large energy production systems towards decentralized production and distribution. Renewable-based power plants, largely weather-dependent (typically wind and solar power plants), are increasingly present in the world’s energy mix.

The Role of Entropy in Guiding a Connection Prover

Publication
September 6, 2021
publications
In this work we study how to learn good algorithms for selecting reasoning steps in theorem proving. We explore this in the connection tableau calculus implemented by leanCoP where the partial tableau provides a clean and compact notion of a state to which a limited number of inferences can be applied. We start by incorporating a state-of-the-art learning algorithm — a graph neural network (GNN) – into the plCoP theorem prover.
