Abstract: An online system receives explicit user data and explicit event data, and implicit user data and implicit event data from a third party system. The online system generates an implicit users/implicit events data feature, an explicit users/explicit events data feature, and an explicit users/implicit events data feature. The online system generates a prediction of the counterfactual rate based on the implicit users/implicit events data feature, the explicit users/explicit events data feature, and the explicit users/explicit events data feature, the counterfactual rate indicating the likelihood that target users matching certain characteristics caused an event to occur when the target are not been presented with content by the online system, the content configured to induce users to cause the event to occur. A combined prediction rate is presented to the third party system based on the counterfactual rate.

Abstract: Disclosed here is a system that can obtain attributes of an advertisement, where an attribute has a continuous value, and a range of acceptable values is uncertain. The system can create a file including contents that when provided to a predetermined function produce a value of the attribute. Based on the file, the system can generate values corresponding to the attributes. Based on the generated values, the system can create the advertisement. The system can obtain a response data to the created advertisement and can fit a multidimensional function to the attributes and the user response data. Based on the multidimensional function, the system can determine next values and next ranges, where the next values and the next ranges indicate an improvement in the response data.

Abstract: An online system generates predicted outcomes for a content distribution program that distributes content to users of the online system, the predicted outcome indicating a likelihood for the occurrence of an outcome of a content presentation. The online system transmits the one or more predicted outcomes to the third-party system, and receives prediction improvement data from the third-party system, the prediction improvement data indicating an adjustment to errors in the predicted outcomes based on a prediction by the third-party system. The online system updates the properties of a content distribution program based on the prediction improvement data, the updated content distribution program causing the online system to generate new predicted outcomes based on the prediction improvement data in content presentation opportunities. The online system also transmits content to users of the online system based on the updated content distribution program.

Abstract: An online system accesses a list of features used as input into a predictor to predict a performance metric for content presented to users. The online system computes importance scores for one or more of the features. A ranked list of categories is created, with each category having one or more sub-categories. For each feature having a computed importance score, the online system assigns, for each attribute in the ranked list of attributes for that feature, the feature to a sub-category in one of the categories in the ranked list of categories that has the same rank as the attribute in the ranked list of attributes for the feature, where the sub-category is associated with a label that corresponds with the attribute. For each sub-category in each category, a cumulative score is computed for the sub-category based on the importance scores of the features of that sub-category.

Abstract: An online system ranks content eligible for presentation to an online system user based on a prediction made by a general model or a specific model indicating a likelihood that the user will interact with a content item, in which the specific model has a higher latency than the general model. The online system determines which prediction to use for the ranking by balancing the benefit of a more accurate prediction made by the specific model against the higher latency of the specific model. The online system outputs the predicted likelihood from one of the models based on the determination, ranks content items eligible for presentation to the user based on the output, and selects content item(s) for presentation to the user based on the ranking. The online system may log the predicted likelihoods from both models, the outputted predicted likelihood, and information describing the performance of the content item.

Abstract: A system receives a first plurality of impressions associated with a first set of features. Labels for the first plurality is generated based on the first set of features. A machine learning model is trained based on the first set of features and the labels. A second plurality of impressions associated with a second set of features is received. A first estimated probability measuring conversion likelihood when impression delivery occurs is generated based on applying the second plurality and the second set of features to the model. A plurality of holdout impressions associated with a third set of features is identified. A second estimated probability measuring conversion likelihood when impression delivery is withheld is generated based on applying the plurality of holdout impressions and the third set of features to the model. Increased valued (e.g., lift) is estimated based on subtracting the second estimated probability from the first estimated probability.

Abstract: An online system accesses a model attribute store, which stores configuration information and model performance scores for a plurality of models, each model used to predict performance metrics regarding content from a third party system presented to users of the online system. The online system trains a meta-model classifier using the models in the model attribute store, the meta-model classifier trained to predict, for a candidate model, a predicted model performance score of that candidate model. The online system also generates a plurality of candidate models for input to the meta-model classifier, each of the plurality of candidate models including a distinct set of configuration information. The predicted model performance scores for a selected candidate model in the plurality of candidate models is computed using the meta-model classifier, and the online system transmits a report to the third party system indicating predicted model performance score for the selected candidate model.

Abstract: An online system, such as a social networking system, generates shared models for one or more clusters of categories. A shared model for a cluster is common to the categories assigned to the cluster. In this manner, the shared models are specific to the group of categories (e.g., selected content providers) in each cluster while requiring a reasonable computational complexity for the online system. The categories are clustered based on the performance of a model specific to a category on data for other categories.
