Re: ChatGPT?
I tried it. It is quite impressive what it can do. But the problem is that the output cannot be really trusted. Sometimes it is correct and sometimes it provides incorrect information. I guess that there will be some improvement to fix that problem in the future. In the meantime, I think one certain...

Re: Episode and sequential patterns
Episode mining and sequential pattern mining are both data mining techniques used to uncover patterns in a sequence of events . The main difference between them is that episode mining seeks to identify patterns that occur in a single sequence, while sequential pattern mining looks for patterns that...

Re: What are the main limitations of K-means?
Some important limitations of K-means are that it is sensitive to outliers, it requires the specification of the number of clusters, and it tend to produce clusters that have globular shapes. Also K-means is not suitable for clustering data with non-numeric features or categorical data, as it relies...

Re: SPMF Implementation of VMSP
Thank you for the crystal clear, detailed explanations. I understand why we would compare the support of the potential containee and container patterns, if maxgap is not set. But can we still have this optimization when maxgap is set? Given the two patterns I previously cited (obtained with maxgap ...
