Description

Data, derived results, and reservoir training code underlying the article
"Photo-induced currents and short-term memory for reservoir computing in a
ferroelectric semiconductor".

The record is organised by figure. It contains: current-voltage characteristics,
photocurrent relaxation traces for Ohmic and Schottky contacts, paired-pulse
facilitation measurements, the full measured photocurrent response to a 400-pulse light
sequence, the light-pulse input sequence, averaged pulse responses grouped by "past"
pulse level, recognition accuracy as a function of training-set size for the reservoir /
no-reservoir / simulated configurations, a baseline-drift correction, an accuracy-versus-
node-count scan, and a double-exponential fit to the photocurrent decay. Both the
as-measured data (in physical units) and the plotted/normalized traces are provided,
together with the recipes needed to go from one to the other.

The reservoir training code (fig3/reservoir_readout.py) is standalone and reproduces the
published recognition accuracies from the data in this record.

See README.md for the full figure-to-file map, data dictionary, and processing recipes.
