ICML 20202020We consider recovering a causal graph in presence of latent variables, where we seek to minimize the cost of interventions used in the recovery process. We consider two intervention cost models: (1) a linear cost model where the cost of an intervention on a subset of variables has a linear form, and (2) an identity cost model where the cost of an intervention is the same, regardless of what variables it

ICML 20202020We introduce a new way of learning to encode position information for non-recurrent models, such as Transformer models. Unlike RNN and LSTM, which contain inductive bias by loading the input tokens sequentially, non-recurrent models are less sensitive to position. The main reason is that position information among input units is not inherently encoded, i.e., the models are permutation equivalent; this problem

ICML 20202020Extreme multi-label classification (XMC) is the problem of finding the relevant labels for an input, from a very large universe of possible labels. We consider XMC in the setting where labels are available only for groups of samples - but not for individual ones. Current XMC approaches are not built for such multi-instance multi-label (MIML) training data, and MIML approaches do not scale to XMC sizes.

ICML 2020 Workshop on AutoML2020Bayesian optimization (BO) is a class of global optimization algorithms ubiquitous in hyperparameter optimization (HPO). BO budgets are typically given in iterations, which implicitly measures convergence in terms of the number of hyperparameter evaluations. In practice, evaluation costs may vary in different regions of the search space. For example, the cost of neural network training increases quadratically

ICML 2020 Workshop on AutoML2020Given the increasing importance of machine learning (ML) in our lives, algorithmic fairness techniques have been proposed to mitigate biases that can be amplified by ML. Commonly, these specialized techniques apply to a single family of ML models and a specific definition of fairness, limiting their effectiveness in practice. We introduce a general constrained Bayesian optimization (BO) framework to optimize
