Predictability over Volatility: When simple strategies help households save on fuel
Shahrzad Jamshidi, Ako Ogihara
What reasonable strategies can households use to save on gasoline or diesel purchases under different pricing functions? We assess basic strategies households might employ under a…
Algebraic Expressivity Certificates for Shallow Polynomial Neural Networks
Sepehr Akbari, Shahrzad Jamshidi
We study exact representability by bias-free shallow polynomial neural networks using algebraic geometry. Over , a width- network with activation comp…

Ricardo Salazar, Shahrzad Jamshidi
Define a building blocks set to be a collection of n cubes (each with six sides) where each side is assigned one letter and one color from a palette of m colors. We propose a novel…
A Brain Age Residual Biomarker (BARB): Leveraging MRI-Based Models to Detect Latent Health Conditions in U.S. Veterans
Shahrzad Jamshidi, Arthur Bousquet, Sugata Banerji +2
Age prediction using brain imaging, such as MRIs, has achieved promising results, with several studies identifying the model's residual as a potential biomarker for chronic disease…
