Is it possible to use Frequency Filter (term frequency (TF) and inverse document frequency (IDF) in text processing for forex data?For example is it possible to get the frequency of the percentage change value between the current daily close price and the previous daily close price?Then the new data will be fed into one of the machine learning algorithm of Knime platform.Is this possible?Thanks.
Hi there @tovim,
welcome to KNIME Community!
Not sure how Forex data looks like but don’t think you want to use those nodes (from text processing) for getting the count of the percentage change. How about GroupBy node with aggregation Unique concatenate with count?
Thank you very much,very kind of you.Yes ,GroupBy node with aggregation Unique concatenate with count looks the right choice.
glad it helped
