Certifying Hidden Dissipation from Observed Current Fluctuations
Ahmed Roman
A single-molecule experiment on a driven enzyme or motor resolves only a few of the transitions the machine makes, yet one would like to know how much free energy it dissipates in…
Simultaneous Dimensionality Reduction: A Data Efficient Approach for Multimodal Representations Learning
Eslam Abdelaleem, Ahmed Roman, K. Michael Martini +1
We explore two primary classes of approaches to dimensionality reduction (DR): Independent Dimensionality Reduction (IDR) and Simultaneous Dimensionality Reduction (SDR). In IDR me…
Measuring gravitational force from Femto-gram source masses
Ahmed Roman, Asem Hassan, Mohamed ElKabbash
Gravity is the weakest of all known forces. Measuring the force of gravity from micro and nano-scale source masses is an essential first step toward low-energy quantum gravity test…
Low probability states, data statistics, and entropy estimation
Damián G. Hernández, Ahmed Roman, Ilya Nemenman
A fundamental problem in analysis of complex systems is getting a reliable estimate of entropy of their probability distributions over the state space. This is difficult because un…
Multi-dimensional structure of C. elegans thermal learning
Ahmed Roman, Konstantine Palanski, Ilya Nemenman +1
Quantitative models of associative learning that explain the behavior of real animals with high precision have turned out very difficult to construct. We do this in the context of…
Ballistic deposition with memory: a new universality class of surface growth with a new scaling law
Ahmed Roman, Ruomin Zhu, Ilya Nemenman
Motivated by recent experimental studies in microbiology, we suggest a modification of the classic ballistic deposition model of surface growth, where the memory of a deposition at…
