Haldane Bundles: A Dataset for Learning to Predict the Chern Number of Line Bundles on the Torus

1 code implementation6 Dec 2023 Cody Tipton, Elizabeth Coda, Davis Brown, Alyson Bittner, Jung Lee, Grayson Jorgenson, Tegan Emerson, Henry Kvinge

Characteristic classes, which are abstract topological invariants associated with vector bundles, have become an important notion in modern physics with surprising real-world consequences.

Understanding the Inner Workings of Language Models Through Representation Dissimilarity

no code implementations23 Oct 2023 Davis Brown, Charles Godfrey, Nicholas Konz, Jonathan Tu, Henry Kvinge

As language models are applied to an increasing number of real-world applications, understanding their inner workings has become an important issue in model trust, interpretability, and transparency.

Attributing Learned Concepts in Neural Networks to Training Data

no code implementations4 Oct 2023 Nicholas Konz, Charles Godfrey, Madelyn Shapiro, Jonathan Tu, Henry Kvinge, Davis Brown

By now there is substantial evidence that deep learning models learn certain human-interpretable features as part of their internal representations of data.

On Privileged and Convergent Bases in Neural Network Representations

no code implementations24 Jul 2023 Davis Brown, Nikhil Vyas, Yamini Bansal

Our findings give evidence that while Linear Mode Connectivity improves with increased network width, this improvement is not due to an increase in basis correlation.

How many dimensions are required to find an adversarial example?

no code implementations24 Mar 2023 Charles Godfrey, Henry Kvinge, Elise Bishoff, Myles Mckay, Davis Brown, Tim Doster, Eleanor Byler

Past work exploring adversarial vulnerability have focused on situations where an adversary can perturb all dimensions of model input.

Fast computation of permutation equivariant layers with the partition algebra

no code implementations10 Mar 2023 Charles Godfrey, Michael G. Rawson, Davis Brown, Henry Kvinge

The space of permutation equivariant linear layers is a generalization of the partition algebra, an object first discovered in statistical physics with deep connections to the representation theory of the symmetric group, and the basis described above generalizes the so-called orbit basis of the partition algebra.

Exploring the Representation Manifolds of Stable Diffusion Through the Lens of Intrinsic Dimension

no code implementations16 Feb 2023 Henry Kvinge, Davis Brown, Charles Godfrey

We find that choice of prompt has a substantial impact on the intrinsic dimension of representations at both layers of the model which we explored, but that the nature of this impact depends on the layer being considered.

Experimental Observations of the Topology of Convolutional Neural Network Activations

no code implementations1 Dec 2022 Emilie Purvine, Davis Brown, Brett Jefferson, Cliff Joslyn, Brenda Praggastis, Archit Rathore, Madelyn Shapiro, Bei Wang, Youjia Zhou

Topological data analysis (TDA) is a branch of computational mathematics, bridging algebraic topology and data science, that provides compact, noise-robust representations of complex structures.

Internal Representations of Vision Models Through the Lens of Frames on Data Manifolds

no code implementations19 Nov 2022 Henry Kvinge, Grayson Jorgenson, Davis Brown, Charles Godfrey, Tegan Emerson

While the last five years have seen considerable progress in understanding the internal representations of deep learning models, many questions remain.

Testing predictions of representation cost theory with CNNs

1 code implementation3 Oct 2022 Charles Godfrey, Elise Bishoff, Myles Mckay, Davis Brown, Grayson Jorgenson, Henry Kvinge, Eleanor Byler

It is widely acknowledged that trained convolutional neural networks (CNNs) have different levels of sensitivity to signals of different frequency.

The SVD of Convolutional Weights: A CNN Interpretability Framework

no code implementations14 Aug 2022 Brenda Praggastis, Davis Brown, Carlos Ortiz Marrero, Emilie Purvine, Madelyn Shapiro, Bei Wang

Fully connected layers can be studied by decomposing their weight matrices using a singular value decomposition, in effect studying the correlations between the rows in each matrix to discover the dynamics of the map.

On the Symmetries of Deep Learning Models and their Internal Representations

2 code implementations27 May 2022 Charles Godfrey, Davis Brown, Tegan Emerson, Henry Kvinge

In this paper we seek to connect the symmetries arising from the architecture of a family of models with the symmetries of that family's internal representation of data.

Making Corgis Important for Honeycomb Classification: Adversarial Attacks on Concept-based Explainability Tools

no code implementations14 Oct 2021 Davis Brown, Henry Kvinge

Methods for model explainability have become increasingly critical for testing the fairness and soundness of deep learning.
