Abstract: A determination is made that an explanatory data set for a common set of predictions generated by a machine learning model for records containing text tokens is to be provided. Respective groups of related tokens are identified from the text attributes of the records, and record-level prediction influence scores are generated for the token groups. An aggregate prediction influence score is generated for at least some of the token groups from the record-level scores, and an explanatory data set based on the aggregate scores is presented.

Abstract: Systems and methods for implementing auditing of large language model-based tools for bias in inferences is disclosed. Individual entries of the dataset of dialogs may be modified to include stereotypical details of particular contexts. These modified records may then be submitted to an automated response generator to produce a set benchmark records. The baseline records and benchmark records may then be analyzed for completeness, accuracy and conciseness with respect to the particular contexts and disparities in precision and recall may be determined using differences in the benchmark and baseline records. The determined disparities may then be used to further train or fine-tune the automated response generator.

Abstract: Automatic failure diagnosis and correction may be performed on trained machine learning models. Input data that causes a trained machine learning model may be identified in order to determine different model failures. The model failures may be clustered in order to determine failure scenarios for the trained machine learning model. Examples of the failure scenarios may be generated and truth labels for the example scenarios obtained. The examples and truth labels may then be used to retrain the machine learning model to generate a corrected version of the machine learning model.

Abstract: An algorithm releases answers to very large numbers of statistical queries, e.g., k-way marginals, subject to differential privacy. The algorithm answers queries on a private dataset using simple perturbation, and then attempts to find a synthetic dataset that most closely matches the noisy answers. The algorithm uses a continuous relaxation of the synthetic dataset domain which makes the projection loss differentiable, and allows the use of efficient machine learning optimization techniques and tooling. Rather than answering all queries up front, the algorithm makes judicious use of a privacy budget by iteratively and adaptively finding queries for which relaxed synthetic data has high error, and then repeating the projection. The algorithm is effective across a range of parameters and datasets, especially when a privacy budget is small or a query class is large.

Abstract: A set of clusters from a first set of vector representations (VRs) is identified. A center associated with each cluster from the set of clusters to generate a set of centers is determined. For each VR from the first set of VRs, and to generate a first set of distributions, a distribution of that VR is determined that indicates, for each center from the set of centers, similarity between that VR and that center. For each VR from a second set of VRs, and to generate a second set of distributions, a distribution of that VR is determined that indicates, for each center from the set of centers, similarity between that VR and that center. A set of divergence metrics associated with the first set of VRs and the second set of VRs are computed based on comparing the first set of distributions and the second set of distributions.

Abstract: In an example, each of a plurality of members of social networking service is mapped to a weighted skill vector, each weighted skill vector including a list of skills for the member with an associated weight indicating strength of the skill. Members of the social networking service that belong to an industry are aggregated to obtain a weighted matrix of members and skills along with compensation vectors indicating compensation for each of the members in the matrix. The weighted matrix of users and skills and corresponding compensation vectors is used to train a machine learning skill monetary value prediction model to output a predicted monetary value for one or more skills contained in a candidate vector fed to the machine learning skill monetary value prediction model.
