Axis 0是沿着行前进的方向 Axis 1是沿着列前进的方向 NumPy数组的axes起始值是0 Python列表的元素的索引值是从0开始计数的,NumPy数组的axes值和Python列表的索引值一样,也是从0开始计数的。 举例说明如何使用NumPy的axes 以函数sum举例 首先,导入numpy,创建一个shape为(2, 3)的数组,初始值设为0到6的序列. imp...
Pandas is the most popular software library for data manipulation and data analysis for the Python programming language. It strengthens Python’s ability to work with spreadsheet-like data with functionality that allows for fast loading, aligning, manipu
The numpy.ndarray.shape() returns the shape of our ndarray as a tuple. For a 1D array, the shape would be (n,) where n is the number of elements in your array.For a 2D array, the shape would be (n,m) where n is the number of rows and m is the number of columns in your ...

We have the samples of the dataset on the x-axis and the distance on the y-axis. Whenever two clusters are merged, we will join them in this dendrogram, and the height of the join will be the distance between these points. Let’s build the dendrogram for our example: ...

Theano is an open source project that was developed by the MILA group at the University of Montreal, Quebec, Canada. It was the first widely used Framework. It is a Python library that helps in multi-dimensional arrays for mathematical operations using Numpy or Scipy. Theano can use GPUs for...
Suppose that a bank is deciding whether to approve or reject loan applications. The bank uses two features to make this decision: the applicant's credit score and annual income. Here, the two features or classes are plotted on a 2-dimensional (2D) plane with an X-Y axis. If we tried ...
