Structural Decomposition of UV--Visible Spectral Variation: Azobenzene in Ethanol Solution
Eemeli A. Eronen, Johannes Niskanen
We present a structural interpretation of statistical variability in simulated liquid-phase UV--visible absorption spectra. We analyze the significant variation of the spectral res…

Encoder-Decoder Neural Networks in Interpretation of X-ray Spectra
Jalmari Passilahti, Anton Vladyka, Johannes Niskanen
Encoder--decoder neural networks (EDNN) condense information most relevant to the output of the feedforward network to activation values at a bottleneck layer. We study the use of…

Implementation of the Emulator-based Component Analysis
Anton Vladyka, Eemeli A. Eronen, Johannes Niskanen
We present a PyTorch-powered implementation of the emulator-based component analysis used for ill-posed numerical non-linear inverse problems, where an approximate emulator for the…
