Could I use the imputation methods to upsample my low-frequency data? #419

Issue description

Hello, Mr. Du! I am a graduate student from the School of Software at Beihang University, majoring in time series analysis. I have been researching time series imputation recently and happened to see your related research, including papers and codes, which has greatly inspired me. Now I have a small question to ask you, can the imputation method be applied to the task of upsampling low-frequency data? My initial idea is to use the resample method of data analysis libraries such as Pandas to resample low-frequency data at a higher frequency. At this time, there will be many missing data. For these missing data, use the model in your PYPOTS library for imputation. Do you think this approach is reasonable?

Hi @mike-egg123, worth a shot, but the final results depend on your data's attributes, e.g. the original sampling freq of raw data. You can reach out to me on WeChat.
