A computing device computes curve descriptive values to correct an error estimate of a prediction. A predefined number of times, an input dataset is split into a training dataset and a validation dataset, a predictive model and a domain model are trained, the trained predictive model and the trained domain model are validated, a predictive error value, a residual value, and a domain error value are computed, and each value is stored in output data. A domain threshold value is computed from the stored domain error values. Each predictive error value and each residual value stored in the output data is stored in in-domain output data when a respective domain error value is less than or equal to the computed domain threshold value. Curve descriptive values are computed to describe a relationship between the residual values as a function of the prediction error values stored in the in-domain output data.

System for automatic error estimate correction for a machine learning model

Solid oxide fuel cells (SOFCs) are provided. A SOFC may comprise a cathode, an anode, and a solid oxide electrolyte between the anode and the cathode, wherein the cathode comprises a perovskite compound. The perovskite compound may be characterized by a log k* value which is less negative than about &#x2212;6.0 cm/s; an energy above the convex hull of less than about 40 meV/(formula unit); a bandgap of about 0 and a charge transfer gap of about 0.

Perovskite compounds for stable, high activity solid oxide fuel cell cathodes and other applications

An electron emitter device is provided comprising a cathode comprising a conductive transition metal perovskite oxide comprising mobile conducting electrons exhibiting a conductivity of at least 10&#x3a9;-cmat room temperature, the transition metal perovskite oxide having a surface from which the mobile electrons are induced to emit upon receiving sufficient energy from an energy source; and an anode electrically coupled to the cathode and positioned to define an interelectrode conductive region between the anode and the cathode, onto which anode the emitted electrons are collected. The transition metal perovskite oxide may have formula SrBaVO. Related methods and devices based on the electron emitter device are also provided.
