SIGIR 2022 Workshop on Reaching Efficiency in Neural Information Retrieval2022The Plackett-Luce (PL) model is popular in learning-to-rank (LTR) because it provides a useful and intuitive probabilistic model for sampling ranked lists. Counterfactual offline evaluation and optimization of ranking metrics are pivotal for using LTR methods in production. When adopting the PL model as a ranking policy, both tasks require the computation of expectations with respect to the model. These

Interspeech 20222022In this paper, we propose GlowVC: a multilingual multi-speaker flow-based model for language-independent text-free voice conversion. We build on Glow-TTS, which provides an architecture that enables use of linguistic features during training without the necessity of using them for VC inference. We consider two versions of our model: GlowVC-conditional and GlowVC-explicit. GlowVC-conditional models the distribution

ICML 20222022This paper demonstrates how to recover causal graphs from the score of the data distribution in non-linear additive (Gaussian) noise models. Using score matching algorithms as a building block, we show how to design a new generation of scalable causal discovery methods. To showcase our approach, we also propose a new efficient method for approximating the score’s Jacobian, enabling to recover the causal

KDD 20222022In package-handling facilities, boxes of varying sizes are used to ship products. Improperly sized boxes with box dimensions much larger than the product dimensions create wastage and unduly increase the shipping costs. Since it is infeasible to make unique, tailor-made boxes for each of the N products, the fundamental question that confronts e-commerce companies is: “How many K << N cuboidal boxes need

Interspeech 20222022Traditional acoustic echo cancelers require that the reference and microphone signals have exactly the same sampling frequency. In this paper, we present a novel Kalman filtering approach to acoustic echo cancellation (AEC) which blindly accounts for the clock skew between the playback and recording devices without the need for exchanging timestamps when they have independent clocks. The proposed Kalman-filter
