Abstract: A membrane electrode with ultra-low oxygen mass transfer resistance includes an anode catalyst layer, a proton exchange membrane (PEM), and a cathode catalyst layer. A catalyst in the cathode catalyst layer is negatively charged, and the cathode catalyst layer is further doped with a negatively charged carbon carrier. A carbon carrier of the cathode catalyst layer in the membrane electrode is negatively charged, thereby optimizing the distribution of ionomers to achieve the purpose of reducing an oxygen mass transfer resistance in the cathode catalyst layer. In addition, an appropriate amount of the negatively charged carbon carrier is doped to increase a local oxygen concentration near active sites. In conclusion, the two methods of modifying with a negative charge and doping a negatively charged carbon carrier are used to optimize the local mass transfer resistance in an electrode and thus improve the cell performance.

Abstract: The described implementations are operable to determine potential objects of interest to a user based on a blend of the user's long-term behavior and short-term interests. Long term user behavior may be determined for the user over a period of time and represented as continuous data. Short-term interest may be determined based on objects with which the user has recently interacted, and attributes of those objects may be represented together as continuous data corresponding to the short-term user interest. The continuous data of the short-term user interest and long-term user behavior may be blended to produce a user embedding. The user embedding may then be compared with objects to determine objects that are of potential interest to the user.

Abstract: Systems, methods, and other embodiments associated with detecting unfairness in machine learning outcomes are described. In one embodiment, a method includes generating outcomes for transactions with a machine learning tool to be tested for bias. Then, actual values for a test subset of the outcomes that is associated with a test value for a demographic classification are compared with estimated values for the test subset of outcomes. The estimated values are generated by a machine learning model that is trained with a reference subset of the outcomes that are associated with a reference value for the demographic classification. The method then detects whether the machine learning tool is biased or unbiased based on dissimilarity between the actual values and the estimated values for the test subset of the outcomes. The method then generates an electronic alert that the ML tool is biased or unbiased.

The estimates are written to the stream of estimates in real time upon generation.
