There is currently no mathematically-rigorous framework for comparing the finite bases available to discretize a CST domain. Following from the Bayesian formulation of tomographic inversion, we show that Bayesian model selection can identify the mesh density, mode of interpolation, and prior information best-suited to reconstruct a set of measurement data. We validate this procedure with a simulated CST experiment, and generate accurate reconstructions despite limited measurement information. The flow field is represented using the finite element method, and Bayesian model selection is used to choose between three forms of polynomial support for a range of mesh resolutions, as well as four priors. We show that the model likelihood of Bayesian model selection is a good predictor of reconstruction accuracy.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4KPHJlc291cmNlIHhtbG5zOnhzaT0iaHR0cDovL3d3dy53My5vcmcvMjAwMS9YTUxTY2hlbWEtaW5zdGFuY2UiIHhtbG5zPSJodHRwOi8vZGF0YWNpdGUub3JnL3NjaGVtYS9rZXJuZWwtNCIgeHNpOnNjaGVtYUxvY2F0aW9uPSJodHRwOi8vZGF0YWNpdGUub3JnL3NjaGVtYS9rZXJuZWwtNCBodHRwOi8vc2NoZW1hLmRhdGFjaXRlLm9yZy9tZXRhL2tlcm5lbC00L21ldGFkYXRhLnhzZCI+CiAgPGlkZW50aWZpZXIgaWRlbnRpZmllclR5cGU9IkRPSSI+MTAuNjA4NC9NOS5GSUdTSEFSRS5DLjM4MzIyMjU8L2lkZW50aWZpZXI+CiAgPGNyZWF0b3JzPgogICAgPGNyZWF0b3I+CiAgICAgIDxjcmVhdG9yTmFtZSBuYW1lVHlwZT0iUGVyc29uYWwiPkdyYXVlciwgU2FtdWVsPC9jcmVhdG9yTmFtZT4KICAgICAgPGdpdmVuTmFtZT5TYW11ZWw8L2dpdmVuTmFtZT4KICAgICAgPGZhbWlseU5hbWU+R3JhdWVyPC9mYW1pbHlOYW1lPgogICAgPC9jcmVhdG9yPgogICAgPGNyZWF0b3I+CiAgICAgIDxjcmVhdG9yTmFtZSBuYW1lVHlwZT0iUGVyc29uYWwiPkhhZHdpbiwgUGF1bDwvY3JlYXRvck5hbWU+CiAgICAgIDxnaXZlbk5hbWU+UGF1bDwvZ2l2ZW5OYW1lPgogICAgICA8ZmFtaWx5TmFtZT5IYWR3aW48L2ZhbWlseU5hbWU+CiAgICA8L2NyZWF0b3I+CiAgICA8Y3JlYXRvcj4KICAgICAgPGNyZWF0b3JOYW1lIG5hbWVUeXBlPSJQZXJzb25hbCI+U2lwa2VucywgVGltb3RoeTwvY3JlYXRvck5hbWU+CiAgICAgIDxnaXZlbk5hbWU+VGltb3RoeTwvZ2l2ZW5OYW1lPgogICAgICA8ZmFtaWx5TmFtZT5TaXBrZW5zPC9mYW1pbHlOYW1lPgogICAgPC9jcmVhdG9yPgogICAgPGNyZWF0b3I+CiAgICAgIDxjcmVhdG9yTmFtZSBuYW1lVHlwZT0iUGVyc29uYWwiPkRhdW4sIEt5bGU8L2NyZWF0b3JOYW1lPgogICAgICA8Z2l2ZW5OYW1lPkt5bGU8L2dpdmVuTmFtZT4KICAgICAgPGZhbWlseU5hbWU+RGF1bjwvZmFtaWx5TmFtZT4KICAgIDwvY3JlYXRvcj4KICA8L2NyZWF0b3JzPgogIDx0aXRsZXM+CiAgICA8dGl0bGU+RGF0YS1CYXNlZCBNZXNoIFNlbGVjdGlvbiBpbiBDaGVtaWNhbCBTcGVjaWVzIFRvbW9ncmFwaHk8L3RpdGxlPgogIDwvdGl0bGVzPgogIDxwdWJsaXNoZXI+Rmlnc2hhcmU8L3B1Ymxpc2hlcj4KICA8cHVibGljYXRpb25ZZWFyPjIwMTc8L3B1YmxpY2F0aW9uWWVhcj4KICA8cmVzb3VyY2VUeXBlIHJlc291cmNlVHlwZUdlbmVyYWw9IkNvbGxlY3Rpb24iPkNvbGxlY3Rpb248L3Jlc291cmNlVHlwZT4KICA8c3ViamVjdHM+CiAgICA8c3ViamVjdCBzdWJqZWN0U2NoZW1lPSJGT1IiPjkxNTAxIENvbXB1dGF0aW9uYWwgRmx1aWQgRHluYW1pY3M8L3N1YmplY3Q+CiAgICA8c3ViamVjdCBzdWJqZWN0U2NoZW1lPSJGaWVsZHMgb2YgU2NpZW5jZSBhbmQgVGVjaG5vbG9neSAoRk9TKSIgc2NoZW1lVVJJPSJodHRwOi8vd3d3Lm9lY2Qub3JnL3NjaWVuY2UvaW5uby8zODIzNTE0Ny5wZGYiPkZPUzogT3RoZXIgZW5naW5lZXJpbmcgYW5kIHRlY2hub2xvZ2llczwvc3ViamVjdD4KICAgIDxzdWJqZWN0IHN1YmplY3RTY2hlbWU9IkZPUiI+OTA0MDMgQ2hlbWljYWwgRW5naW5lZXJpbmcgRGVzaWduPC9zdWJqZWN0PgogICAgPHN1YmplY3Qgc3ViamVjdFNjaGVtZT0iRmllbGRzIG9mIFNjaWVuY2UgYW5kIFRlY2hub2xvZ3kgKEZPUykiIHNjaGVtZVVSST0iaHR0cDovL3d3dy5vZWNkLm9yZy9zY2llbmNlL2lubm8vMzgyMzUxNDcucGRmIj5GT1M6IENoZW1pY2FsIGVuZ2luZWVyaW5nPC9zdWJqZWN0PgogICAgPHN1YmplY3Q+TWVjaGFuaWNhbCBFbmdpbmVlcmluZzwvc3ViamVjdD4KICAgIDxzdWJqZWN0IHN1YmplY3RTY2hlbWU9IkZpZWxkcyBvZiBTY2llbmNlIGFuZCBUZWNobm9sb2d5IChGT1MpIiBzY2hlbWVVUkk9Imh0dHA6Ly93d3cub2VjZC5vcmcvc2NpZW5jZS9pbm5vLzM4MjM1MTQ3LnBkZiI+Rk9TOiBNZWNoYW5pY2FsIGVuZ2luZWVyaW5nPC9zdWJqZWN0PgogICAgPHN1YmplY3Qgc3ViamVjdFNjaGVtZT0iRk9SIj44MDEwNiBJbWFnZSBQcm9jZXNzaW5nPC9zdWJqZWN0PgogICAgPHN1YmplY3Qgc3ViamVjdFNjaGVtZT0iRmllbGRzIG9mIFNjaWVuY2UgYW5kIFRlY2hub2xvZ3kgKEZPUykiIHNjaGVtZVVSST0iaHR0cDovL3d3dy5vZWNkLm9yZy9zY2llbmNlL2lubm8vMzgyMzUxNDcucGRmIj5GT1M6IENvbXB1dGVyIGFuZCBpbmZvcm1hdGlvbiBzY2llbmNlczwvc3ViamVjdD4KICA8L3N1YmplY3RzPgogIDxkYXRlcz4KICAgIDxkYXRlIGRhdGVUeXBlPSJDcmVhdGVkIj4yMDE3LTA3LTIwPC9kYXRlPgogICAgPGRhdGUgZGF0ZVR5cGU9IlVwZGF0ZWQiPjIwMTctMTAtMDM8L2RhdGU+CiAgICA8ZGF0ZSBkYXRlVHlwZT0iSXNzdWVkIj4yMDE3PC9kYXRlPgogIDwvZGF0ZXM+CiAgPHJlbGF0ZWRJZGVudGlmaWVycz4KICAgIDxyZWxhdGVkSWRlbnRpZmllciByZWxhdGVkSWRlbnRpZmllclR5cGU9IkRPSSIgcmVsYXRpb25UeXBlPSJJc1N1cHBsZW1lbnRUbyI+MTAuMTM2NC9vZS4yNS4wMjUxMzU8L3JlbGF0ZWRJZGVudGlmaWVyPgogIDwvcmVsYXRlZElkZW50aWZpZXJzPgogIDxzaXplcy8+CiAgPGZvcm1hdHMvPgogIDx2ZXJzaW9uLz4KICA8cmlnaHRzTGlzdD4KICAgIDxyaWdodHMgcmlnaHRzVVJJPSJodHRwczovL2NyZWF0aXZlY29tbW9ucy5vcmcvbGljZW5zZXMvYnkvNC4wIj5DQyBCWSA0LjA8L3JpZ2h0cz4KICA8L3JpZ2h0c0xpc3Q+CiAgPGRlc2NyaXB0aW9ucz4KICAgIDxkZXNjcmlwdGlvbiBkZXNjcmlwdGlvblR5cGU9IkFic3RyYWN0Ij5HYXMgZGlzdHJpYnV0aW9ucyBpbWFnZWQgYnkgY2hlbWljYWwgc3BlY2llcyB0b21vZ3JhcGh5IChDU1QpIHZhcnkgaW4gcXVhbGl0eSBkdWUgdG8gdGhlIGRpc2NyZXRpemF0aW9uIHNjaGVtZSwgYXJyYW5nZW1lbnQgb2Ygb3B0aWNhbCBwYXRocywgZXJyb3JzIGluIHRoZSBtZWFzdXJlbWVudCBtb2RlbCwgYW5kIHByaW9yIGluZm9ybWF0aW9uIGluY2x1ZGVkIGluIHJlY29uc3RydWN0aW9uLiBUaGVyZSBpcyBjdXJyZW50bHkgbm8gbWF0aGVtYXRpY2FsbHktcmlnb3JvdXMgZnJhbWV3b3JrIGZvciBjb21wYXJpbmcgdGhlIGZpbml0ZSBiYXNlcyBhdmFpbGFibGUgdG8gZGlzY3JldGl6ZSBhIENTVCBkb21haW4uIEZvbGxvd2luZyBmcm9tIHRoZSBCYXllc2lhbiBmb3JtdWxhdGlvbiBvZiB0b21vZ3JhcGhpYyBpbnZlcnNpb24sIHdlIHNob3cgdGhhdCBCYXllc2lhbiBtb2RlbCBzZWxlY3Rpb24gY2FuIGlkZW50aWZ5IHRoZSBtZXNoIGRlbnNpdHksIG1vZGUgb2YgaW50ZXJwb2xhdGlvbiwgYW5kIHByaW9yIGluZm9ybWF0aW9uIGJlc3Qtc3VpdGVkIHRvIHJlY29uc3RydWN0IGEgc2V0IG9mIG1lYXN1cmVtZW50IGRhdGEuIFdlIHZhbGlkYXRlIHRoaXMgcHJvY2VkdXJlIHdpdGggYSBzaW11bGF0ZWQgQ1NUIGV4cGVyaW1lbnQsIGFuZCBnZW5lcmF0ZSBhY2N1cmF0ZSByZWNvbnN0cnVjdGlvbnMgZGVzcGl0ZSBsaW1pdGVkIG1lYXN1cmVtZW50IGluZm9ybWF0aW9uLiBUaGUgZmxvdyBmaWVsZCBpcyByZXByZXNlbnRlZCB1c2luZyB0aGUgZmluaXRlIGVsZW1lbnQgbWV0aG9kLCBhbmQgQmF5ZXNpYW4gbW9kZWwgc2VsZWN0aW9uIGlzIHVzZWQgdG8gY2hvb3NlIGJldHdlZW4gdGhyZWUgZm9ybXMgb2YgcG9seW5vbWlhbCBzdXBwb3J0IGZvciBhIH
