 ## ❖ Citing PyPOTS
+> [!TIP]
+> **[Updates in Feb 2024]** 😎 Our survey paper [Deep Learning for Multivariate Time Series Imputation: A Survey](https://arxiv.org/abs/2402.04059) has been released on arXiv.
+The code is open source in the GitHub repo [Awesome_Imputation](https://github.com/WenjieDu/Awesome_Imputation).
+We comprehensively review the literature of the state-of-the-art deep-learning imputation methods for time series, 
+provide a taxonomy for them, and discuss the challenges and future directions in this field.
+> 
+> **[Updates in Jun 2023]** 🎉 A short version of the PyPOTS paper is accepted by the 9th SIGKDD international workshop on
+Mining and Learning from Time Series ([MiLeTS'23](https://kdd-milets.github.io/milets2023/))).
+**Additionally**, PyPOTS has been included as a [PyTorch Ecosystem](https://pytorch.org/ecosystem/) project.

 The paper introducing PyPOTS is available on arXiv at [this URL](https://arxiv.org/abs/2305.18811),
 and we are pursuing to publish it in prestigious academic venues, e.g. JMLR (track for
 [Machine Learning Open Source Software](https://www.jmlr.org/mloss/)). If you use PyPOTS in your work,
