Hi,
I just added the code to generate the visualizations of the time series as well as predicted segmentations. Check out the updated README.
Cheers, Arik
from time-series-segmentation-benchmark.
How please to generate all the images for all the dataset, i try this but something was wrong.
for _, (ts, ts_name, cps, found_cps) in tssb.iterrows():
import matplotlib.pyplot as plt
from tssb.utils import visualize_time_series
fig, ax = visualize_time_series(ts, ts_name, cps, found_cps)
plt.show()
from time-series-segmentation-benchmark.
The row
for _, (ts, ts_name, cps, found_cps) in tssb.iterrows():
is false. TSSB consists of tuples (ts_name, window_size, cps, ts). Try:
for _, (ts_name, window_size, cps, ts) in tssb.iterrows():
fig, ax = visualize_time_series(ts, ts_name, cps)
plt.savefig(f"images/{ts_name}.png", bbox_inches="tight")
plt.clf()

Thank u, but this is before segmentation prediction, i want after the prediction (found changes points)
from time-series-segmentation-benchmark.
In that case, simply add your predicted change points to the method
fig, ax = visualize_time_series(ts, ts_name, cps, found_cps)
from time-series-segmentation-benchmark.

i did it, but the result was wrong... Like this..
-----for _, (ts_name, window_size, cps, ts) in tssb.iterrows():
fig, ax = visualize_time_series(ts, ts_name, cps, found_cps)
plt.savefig(f"tssb/results/{ts_name}.png", bbox_inches="tight")
plt.clf()-----
and this is an example of the result...

Well, is your prediction
found_cps = your_algorithm_predict(ts)
in the for loop? And also, can you print your prediction (found_cps)? It seems like it is way too large.
from time-series-segmentation-benchmark.
The following code
import numpy as np
import matplotlib.pyplot as plt
from tssb.utils import load_time_series_segmentation_datasets, visualize_time_series
tssb = load_time_series_segmentation_datasets(names=["Adiac"])
for _, (ts_name, window_size, cps, ts) in tssb.iterrows():
found_cps = np.array([1000])
fig, ax = visualize_time_series(ts, ts_name, cps, found_cps)
plt.show()
plt.clf()
leads to the following image:

I'm sorry, but i tried that, and it's correct juste for Adiac.
For example, for beetlefly, i got that
from time-series-segmentation-benchmark.
But this is exactly what you would expect to get for BeetleFly, if your predicted Change Point is at position 1000.

oh yes, i'm stupide.. but how to print for all our predictions, for example like this (but for all images) ...
from time-series-segmentation-benchmark.
Well, you simply predict the CPs in the for loop and save the predicted segmentations.
import numpy as np
import matplotlib.pyplot as plt
from tssb.utils import load_time_series_segmentation_datasets, visualize_time_series
tssb = load_time_series_segmentation_datasets(names=["Adiac"])
for _, (ts_name, window_size, cps, ts) in tssb.iterrows():
found_cps = your_segmentation_algorithm_predict(ts, len(cps))
fig, ax = visualize_time_series(ts, ts_name, cps, found_cps)
plt.savefig(f"images/{ts_name}.png", bbox_inches="tight")
plt.clf()

Yes, now it's okay, thank you very much. This is the final code for your implementation
for _, (ts_name, window_size, cps, ts) in tssb.iterrows():
found_cps = ClaSPSegmentation(window_size, n_cps=len(cps)).fit_predict(ts)
fig, ax = visualize_time_series(ts, ts_name, cps, found_cps)
plt.savefig(f"tssb/results/{ts_name}.png", bbox_inches="tight")
plt.clf()

Yes! You are welcome!
