# Solving fractional Poisson equations on fPE on Unit Ball (d=2, u\_exact = (1 - \|\|x\|\|^2)^(alpha/2)) 1.0 (test) Source: [Solving fractional Poisson equations on fPE on Unit Ball (d=2, u\_exact = (1 - \|\|x\|\|^2)^(alpha/2)) 1.0 (test)]() Collection index: [llms.txt]() Data updated: 2026-06-26T08:57:33.050Z Evaluation of models solving the Fractional Poisson Equation (fPE) on a 2D Unit Ball domain, defined by the specific exact solution u\_exact = (1 - \|\|x\|\|^2)^(alpha/2), version 1.0, measured by Relative L2 test error. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Solving fractional Poisson equations | | Dataset (including any stated split) | fPE on Unit Ball (d=2, u\_exact = (1 - \|\|x\|\|^2)^(alpha/2)) 1.0 (test) | | Metric | Relative L2 Test Error | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 10 of 10 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [Relative L2 Test Error](): Lower is better; unit: SCALAR. ## Recorded results | Method | Relative L2 Test Error | Result date | Report paper | | --- | --- | --- | --- | | fTNN | 0.0000172 | Not recorded | 6a3e079e206542251d7cb557 | | fTNN | 0.0000217 | Not recorded | 6a3e079e206542251d7cb557 | | QE-MC-fPINN | 0.00605 | Not recorded | 6a3e079e206542251d7cb557 | | fPINN | 0.0134 | Not recorded | 6a3e079e206542251d7cb557 | | fPINN | 0.0136 | Not recorded | 6a3e079e206542251d7cb557 | | QE-MC-fPINN | 0.0341 | Not recorded | 6a3e079e206542251d7cb557 | | Improved MC-fPINN | 0.424 | Not recorded | 6a3e079e206542251d7cb557 | | Improved MC-fPINN | 0.512 | Not recorded | 6a3e079e206542251d7cb557 | | MC-fPINN | 0.701 | Not recorded | 6a3e079e206542251d7cb557 | | MC-fPINN | 0.72 | Not recorded | 6a3e079e206542251d7cb557 | ### fTNN Relative L2 Test Error: 0.0000172.
