Consequently, if a data point of time-series stream has been processed, it is quickly discarded and cannot be retrieved so that it yields to a new-coming one.
The tree is constructed using a training data set made of observation data points of time, status/event, and associated predictor covariates.
When there is a new-coming data point of the time-series stream, for each pattern the matching procedure will determine whether the new-coming time-series subsequence is a candidate in case of SUCR-DTW or many new-coming time-series subsequences are candidates in case of ESUCR-DTW.
In addition, when there is a new-coming data point of the time-series stream, the method needs to construct the envelope of c, which is (E_c).
Each data point of real-time PCR, MTT, mammosphere formation, luciferase activity assays and proliferation was run at least in triplicates and independent experiments were performed at least three times.
Note that TUCR-DTW is not suitable for the streaming setting, because the method requires available time-series sequences before the similarity search is done, whereas time-series data points of a time-series stream are only collected at every time tick, unknown beforehand.
To ensure the analyzed data were recorded when the participants were in a steady postural state, only the middle eight seconds (8000 data points) of the time series was used in the subsequent analysis.
Initial velocities (v) were obtained by fitting the data points of the time series to the equation for exponential association and calculating the tangent at 2 minutes, as indicated in Materials and Methods.
The parameters are given by θ →, while y k D (t j ) indicates the value of a data point of state variable k at time j, respectively.
Next, we iteratively compute the next data point of for the other L p time points.
(9) and (11), respectively, to flush out any accumulated error for once every 100,000 coming data points of a time-series stream.
