Feature-Action Design Patterns for Storytelling Visualizations with Time Series Data

no code implementations5 Feb 2024 Saiful Khan, Scott Jones, Benjamin Bach, Jaehoon Cha, Min Chen, Julie Meikle, Jonathan C Roberts, Jeyan Thiyagalingam, Jo Wood, Panagiotis D. Ritsos

Motivated initially by the need to communicate time series data during the COVID-19 pandemic, we developed a novel computer-assisted method for meta-authoring of stories, which enables the design of storyboards that include feature-action patterns in anticipation of potential features that may appear in dynamically arrived or selected data.

MLCommons Cloud Masking Benchmark with Early Stopping

no code implementations11 Dec 2023 Varshitha Chennamsetti, Gregor von Laszewski, Ruochen Gu, Laiba Mehnaz, Juri Papay, Samuel Jackson, Jeyan Thiyagalingam, Sergey V. Samsonau, Geoffrey C. Fox

We provide a description of the cloud masking benchmark, as well as a summary of our submission to MLCommons on the benchmark experiment we conducted.

Zero Coordinate Shift: Whetted Automatic Differentiation for Physics-informed Operator Learning

1 code implementation1 Nov 2023 Kuangdai Leng, Mallikarjun Shankar, Jeyan Thiyagalingam

Automatic differentiation (AD) is a critical step in physics-informed machine learning, required for computing the high-order derivatives of network output w. r. t.

On the Compatibility between Neural Networks and Partial Differential Equations for Physics-informed Learning

1 code implementation1 Dec 2022 Kuangdai Leng, Jeyan Thiyagalingam

Inspired by this pitfall, we prove that a linear PDE up to the $n$-th order can be strictly satisfied by an MLP with $C^n$ activation functions when the weights of its output layer lie on a certain hyperplane, as called the out-layer-hyperplane.

Discovering the building blocks of dark matter halo density profiles with neural networks

no code implementations16 Mar 2022 Luisa Lucie-Smith, Hiranya V. Peiris, Andrew Pontzen, Brian Nord, Jeyan Thiyagalingam, Davide Piras

The additional dimension in the representation contains information about the infalling material in the outer profiles of dark matter halos, thus discovering the splashback boundary of halos without prior knowledge of the halos' dynamical history.

Disentangling Autoencoders (DAE)

no code implementations20 Feb 2022 Jaehoon Cha, Jeyan Thiyagalingam

Noting the importance of factorizing (or disentangling) the latent space, we propose a novel, non-probabilistic disentangling framework for autoencoders, based on the principles of symmetry transformations in group-theory.

Scientific Machine Learning Benchmarks

no code implementations25 Oct 2021 Jeyan Thiyagalingam, Mallikarjun Shankar, Geoffrey Fox, Tony Hey

In this paper, we describe our approach to the development of scientific machine learning benchmarks and review other approaches to benchmarking scientific machine learning.

Deep learning insights into cosmological structure formation

2 code implementations20 Nov 2020 Luisa Lucie-Smith, Hiranya V. Peiris, Andrew Pontzen, Brian Nord, Jeyan Thiyagalingam

We train a three-dimensional convolutional neural network (CNN) to predict the mass of dark matter halos from the initial conditions, and quantify in full generality the amounts of information in the isotropic and anisotropic aspects of the initial density field about final halo masses.
