A Walsh Hadamard Derived Linear Vector Symbolic Architecture

NeurIPS 2024poster

Vector Symbolic Architectures (VSAs) are one approach to developing Neuro-symbolic AI, where two vectors in $\mathbb{R}^d$ are 'bound' together to produce a new vector in the same space. VSAs support the commutativity and associativity of this binding operation, along with an inverse operation, allo…

Holographic Global Convolutional Networks for Long-Range Prediction Tasks in Malware Detection

AISTATS 2024poster

Malware detection is an interesting and valuable domain to work in because it has significant real-world impact and unique machine-learning challenges. We investigate existing long-range techniques and benchmarks and find that they’re not very suitable in this problem area. In this paper, we introdu…

Ten-Guard: Tensor Decomposition for Backdoor Attack Detection in Deep Neural Networks

ICASSP 2024accepted

As deep neural networks and the datasets used to train them get larger, the default approach to integrating them into research and commercial projects is to download a pre-trained model and fine tune it. But these models can have uncertain provenance, opening up the possibility that they embed hidde…

RFC-Net: Learning High Resolution Global Features for Medical Image Segmentation on a Computational Budget (Student Abstract)

AAAI 2023technical

Learning High-Resolution representations is essential for semantic segmentation. Convolutional neural network (CNN) architectures with downstream and upstream propagation flow are popular for segmentation in medical diagnosis. However, due to performing spatial downsampling and upsampling in multipl…

Recasting Self-Attention with Holographic Reduced Representations

ICML 2023poster

In recent years, self-attention has become the dominant paradigm for sequence modeling in a variety of domains. However, in domains with very long sequence lengths the $\mathcal{O}(T^2)$ memory and $\mathcal{O}(T^2 H)$ compute costs can make using transformers infeasible. Motivated by problems in ma…

Deploying Convolutional Networks on Untrusted Platforms Using 2D Holographic Reduced Representations

ICML 2022spotlight

Due to the computational cost of running inference for a neural network, the need to deploy the inferential steps on a third party’s compute environment or hardware is common. If the third party is not fully trusted, it is desirable to obfuscate the nature of the inputs and outputs, so that the thir…

Bringing UMAP Closer to the Speed of Light with GPU Acceleration

AAAI 2021technical

The Uniform Manifold Approximation and Projection (UMAP) algorithm has become widely popular for its ease of use, quality of results, and support for exploratory, unsupervised, supervised, and semi-supervised learning. While many algorithms can be ported to a GPU in a simple and direct fashion, such…

Learning with Holographic Reduced Representations

NeurIPS 2021spotlight

Holographic Reduced Representations (HRR) are a method for performing symbolic AI on top of real-valued vectors by associating each vector with an abstract concept, and providing mathematical operations to manipulate vectors as if they were classic symbolic objects. This method has seen little use o…
