Machine learning empowered Modulation detection for OFDM-based signals

Autor: Pourranjbar, Ali, Kaddoum, Georges, Mba, Verdier Assoume, Garg, Sahil, Singh, Satinder

We propose a blind ML-based modulation detection for OFDM-based technologies. Unlike previous works that assume an ideal environment with precise knowledge of subcarrier count and cyclic prefix location, we consider blind modulation detection while a

Deep Generative Sampling in the Dual Divergence Space: A Data-efficient & Interpretative Approach for Generative AI

Autor: Garg, Sahil, Schneider, Anderson, Raj, Anant, Rasul, Kashif, Nevmyvaka, Yuriy, Gopal, Sneihil, Dhurandhar, Amit, Cecchi, Guillermo, Rish, Irina

Building on the remarkable achievements in generative sampling of natural images, we propose an innovative challenge, potentially overly ambitious, which involves generating samples of entire multivariate time series that resemble images. However, th

$\textbf{S}^2$IP-LLM: Semantic Space Informed Prompt Learning with LLM for Time Series Forecasting

Autor: Pan, Zijie, Jiang, Yushan, Garg, Sahil, Schneider, Anderson, Nevmyvaka, Yuriy, Song, Dongjin

Recently, there has been a growing interest in leveraging pre-trained large language models (LLMs) for various time series applications. However, the semantic space of LLMs, established through the pre-training, is still underexplored and may help yi

Structural Knowledge Informed Continual Multivariate Time Series Forecasting

Autor: Pan, Zijie, Jiang, Yushan, Song, Dongjin, Garg, Sahil, Rasul, Kashif, Schneider, Anderson, Nevmyvaka, Yuriy

Recent studies in multivariate time series (MTS) forecasting reveal that explicitly modeling the hidden dependencies among different time series can yield promising forecasting performance and reliable explanations. However, modeling variable depende

Empowering Time Series Analysis with Large Language Models: A Survey

Autor: Jiang, Yushan, Pan, Zijie, Zhang, Xikun, Garg, Sahil, Schneider, Anderson, Nevmyvaka, Yuriy, Song, Dongjin

Recently, remarkable progress has been made over large language models (LLMs), demonstrating their unprecedented capability in varieties of natural language tasks. However, completely training a large general-purpose model from the scratch is challen

Lag-Llama: Towards Foundation Models for Probabilistic Time Series Forecasting

Autor: Rasul, Kashif, Ashok, Arjun, Williams, Andrew Robert, Ghonia, Hena, Bhagwatkar, Rishika, Khorasani, Arian, Bayazi, Mohammad Javad Darvishi, Adamopoulos, George, Riachi, Roland, Hassen, Nadhir, Biloš, Marin, Garg, Sahil, Schneider, Anderson, Chapados, Nicolas, Drouin, Alexandre, Zantedeschi, Valentina, Nevmyvaka, Yuriy, Rish, Irina

Over the past years, foundation models have caused a paradigm shift in machine learning due to their unprecedented capabilities for zero-shot and few-shot generalization. However, despite the success of foundation models in modalities such as natural
