STUMPY é uma biblioteca Python poderosa e escalável que calcula eficientemente algo chamado matrix profile <https://stumpy.readthedocs.io/en/latest/Tutorial_The_Matrix_Profile.html>__, o que é apenas uma forma acadêmica de dizer "para cada subsequência (verde) dentro da sua série temporal, identifique automaticamente o seu vizinho mais próximo correspondente (cinza)":
.. image:: https://github.com/stumpy-dev/stumpy/blob/main/docs/images/stumpy_demo.gif?raw=true :alt: STUMPY Animated GIF
O importante é que, uma vez calculado o seu matrix profile (painel do meio acima), ele pode ser usado para uma variedade de tarefas de mineração de dados de séries temporais, tais como:
e mais ... <https://www.cs.ucr.edu/~eamonn/100_Time_Series_Data_Mining_Questions__with_Answers.pdf>__Quer você seja um acadêmico, cientista de dados, desenvolvedor de software ou entusiasta de séries temporais, o STUMPY é simples de instalar e nosso objetivo é permitir que você obtenha insights sobre suas séries temporais mais rapidamente. Consulte a documentação <https://stumpy.readthedocs.io/en/latest/>__ para mais informações.
Consulte nossa documentação da API <https://stumpy.readthedocs.io/en/latest/api.html>__ para uma lista completa das funções disponíveis e veja nossos tutoriais <https://stumpy.readthedocs.io/en/latest/tutorials.html>__ para casos de uso de exemplo mais abrangentes.

Para instalar o stumpy a partir do código-fonte, consulte as instruções na documentação <https://stumpy.readthedocs.io/en/latest/install.html>__.
Para entender e apreciar completamente os algoritmos e aplicações subjacentes, é imprescindível que você leia as publicações originais_. Para um exemplo mais detalhado de como usar o STUMPY, consulte a documentação <https://stumpy.readthedocs.io/en/latest/>__ mais recente ou explore nossos tutoriais práticos <https://stumpy.readthedocs.io/en/latest/tutorials.html>__.
Testamos o desempenho do cálculo do matrix profile exato usando a versão compilada com JIT do Numba do código em dados de séries temporais gerados aleatoriamente com vários comprimentos (ou seja, np.random.rand(n)), juntamente com diferentes recursos de hardware de CPU e GPU <hardware_>_.

Os resultados brutos são exibidos na tabela abaixo como Horas:Minutos:Segundos.Milissegundos e com um tamanho de janela constante de m = 50. Observe que esses tempos de execução relatados incluem o tempo necessário para mover os dados do host para todos os dispositivos de GPU. Talvez seja necessário rolar para o lado direito da tabela para ver todos os tempos de execução.

STUMPY suporta Python 3.10+ <https://python3statement.org/>__ e, devido ao uso de nomes/identificadores de variáveis unicode, não é compatível com Python 2.x. Dadas as poucas dependências, o STUMPY pode funcionar em versões mais antigas do Python, mas isso está além do escopo do nosso suporte e recomendamos fortemente que você atualize para a versão mais recente do Python.
Primeiro, verifique as discussões <https://github.com/stumpy-dev/stumpy/discussions>__ e as issues <https://github.com/stumpy-dev/stumpy/issues?utf8=%E2%9C%93&q=>__ no Github para ver se a sua pergunta já foi respondida lá.
