IEEE 2023 Workshop on Machine Learning for Signal Processing (MLSP)2023Low-count time series describe sparse or intermittent events, which are prevalent in large-scale online platforms that capture and monitor diverse data types. Several distinct challenges surface when modelling low-count time series, particularly low signal-to-noise ratios (when anomaly signatures are provably undetectable), and non-uniform performance (when average metrics are not representative of local

Interspeech 20232023We propose a methodology for information aggregation from the various transformer layer outputs of a generic speech Encoder (e.g. WavLM, HuBERT) for the downstream task of Speech Emotion Recognition (SER). The proposed methodology significantly reduces the dependency of model predictions on linguistic content, while leading to competitive performance without requiring costly Encoder re-training. The proposed

ACL 2023 Workshop on Trustworthy Natural Language Processing (TrustNLP)2023The issue of enhancing the robustness of Named Entity Recognition (NER) models against adversarial attacks has recently gained significant attention (Simoncini and Spanakis, 2021; Lin et al., 2021). The existing techniques for robustifying NER models rely on exhaustive perturbation of the input training data to generate adversarial examples, often resulting in adversarial examples that are not semantically

RecSys 2023 Industry Talk2023Personalization plays a critical role in helping customers discover the products and contents they prefer for e-commerce stores. Personalized recommendations differ in contents, target customers, and UI. However, they require a common core capability - the ability to deeply understand customers’ preferences and shopping intents. In this paper, we introduce the MCM (Multi-task pre-trained Customer Model)

Interspeech 20232023Audio privacy has been undertaken using adversarial task training or adversarial models based on GANs, where the models also suppress scoring of other attributes (e.g., emotion, etc.), but embeddings still retain enough information to bypass speaker privacy. We use methods for feature importance from the explainability literature to modify embeddings from adversarial task training, providing a simple and
