Python APInavigate_next mxnet.npnavigate_next Routinesnavigate_next Statisticsnavigate_next mxnet.np.amax. numpy.amax() will find the max value in an array, and numpy.amin() does the same for the min value. In this part of the NumPy course, we explore ways to clean and preprocess data in NumPy. In this article we will discuss how to get the maximum / largest value in a Numpy array and its indices using numpy.amax(). The difference between ``max``/``min`` and ``amax``/``amin`` is: 1. numpy.amax akan menemukan nilai maksimal dalam sebuah array, dan numpy.amin melakukan hal yang sama untuk nilai min. numpy.argmax, Returns the indices of the maximum values along an axis. If I want to find both max and min, I have to call both functions, which requires passing over the (very big) array twice, which seems slow. code: https://github.com/SungchulLee/numpy/blob/master/np.max_vs_np.maximum.ipynb numpy: lla on kolme erilaista toimintoa, jotka vaikuttavat siltä, että niitä voidaan käyttää samoihin asioihin - paitsi että numpy.maximum voi vain käyttää elementtiviisasti, kun taas numpy.max ja numpy.amax voidaan käyttää tietyillä akseleilla tai kaikilla elementeillä. The section also explains what argument functions are and why they are so useful, and introduces ways to combining arrays by stacking and concatenating them.
