tsmp 0.4.15

Fix UBSAN error

tsmp 0.4.14

Fix ASAN/UBSAN errors using RcppParallel

tsmp 0.4.11

Fix in mpx().

tsmp 0.4.9

Fixed MacOSX build.

tsmp 0.4.8

Added MPdist algorithm to compare two time series.
Added find_snippet() that uses MPdist to show representative data.
Added mpx() algorithm that doesn’t depends on FFT.
Added pmp() pan-matrix profile.
Improvement with several implementations in Rcpp. Computation speed is much faster.
Added compute(), analyze() and visualize(). Starting point in the unified API from MPF.

tsmp 0.3.5

Changed mass() to dist_profile(), including options to different algorithms.
Added MASS_V3 and MASS_Weighted to dist_profile() algorithms.
Function dist_profile() allows Query with Gap (QwG) and Approximate Distance Profile (ADP, with PAA)
Fixed long runtime of FFT for some data sizes, using MASS_V3. Issue #36.
Added stompi_update() that updates the matrix profile allowing real-time computation.
Added floss() which can do real-time FLUSS computation.
Added subset operator [ for tsmp objects.
Added tail() and head() for tsmp objects.
Changed find_motif() for MultiMatrixProfile to report Motifs correctly.

tsmp 0.3.4

Added find_discord() and its print() and plot() functions.
Changed plot() for motifs to show where are the neighbors. Same for discord.
Added valmod() for Variable Length Motif Discovery.
Changed find_motif() for compatibility with valmod().

tsmp 0.3.3

Fixed find_chains() not returning the longest chain. Issue #33

tsmp 0.3.2

Fixed Matrix Profile print, dimensions are now reported correctly.
Fixed pipe imports. Issue #22
Fixed bug with vars. Issue #23
Changed package license to GPL-3.
Changed verbose mode, added one more step to separate messages from progression bar.
Fixed SCRIMP and added PRE-SCRIMP, so this is the SCRIMP++. AB-join not yet implemented.
Changed progress bar for a better one from progress package.
Added Print and Plot to SiMPle. Issue #24
Added Print and Plot to Salient.

tsmp 0.3.1

IMPORTANT

This version is a complete restructuration. The API has changed, and the workflow is more friendly. This API is intended to be stable, and from now on any change will pass through the “Deprecated” stage.

Added Features

Outputs have a prettier print format.
Outputs have a plot function. Try to plot a tsmp() output for example.
Now functions can work in %>% (pipe), e.g. tsmp() %>% find_motif(). Except for SDTS that has a proper way to work.
Added a wrapper function called tsmp() that handles the several algorithms available.
Added as.* functions to allow you to switch classes if you want, e.g.: as.matrixprofile().
Changed all functions from dotted.case to snake_case (except as.* functions).
Added Annotation Vectors.
Fixed STOMP crash with Joins.
Added support to query < data in Joins.
SCRIMP (experimental).

tsmp 0.2.15

Code linting.
Added Salient Subsequences search.

tsmp 0.2.14

Added SiMPle (Fast Similarity Matrix Profile for Music Analysis and Exploration).
Added FLUSS (Fast Low-cost Unipotent Semantic Segmentation).
Added [find_chains()] to look for chains primitives.
Added Multivariate MOTIF Search (from mSTOMP)
Changed dependency from beepr to audio (actually beepr depends on audio, so fewer dependencies).
Added a NEWS.md file to track changes to the package.

tsmp 0.2.12

Added Multivariate STOMP parallel version.
Added SDTS algorithm (Scalable Dictionary learning for Time Series).

tsmp 0.1.0

STAMP and STAMP parallel Algorithm.
Multivariate STOMP algorithm.
MASS algorithm.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
