# Similarity Measurement and Classification of Temporal Data Based on Double Mean Representation
## 4 Experimental Validation
### Experimental Methods and Parameter Settings  
Since the SAX-DM, SAX, SAX-TD, and SAX-BD methods are all based on PAA for segmenting time series data, they involve the parameter window size, denoted as \"\(w\).\" Additionally, the SAX, SAX-TD, and SAX-BD methods also involve the parameter symbol table size, denoted as \"alpha.\" For each dataset, we defined a set of parameter settings \begin{table}
