帧间二进制准确率计算的矢量化

可以使用numpy库中的函数，通过对数据进行矢量化处理来提高计算速度。

代码示例：

import numpy as np

def binary_accuracy(y_true, y_pred):
    """
    Computes the binary accuracy between two arrays.

    Args:
        y_true (numpy array): Ground truth labels.
        y_pred (numpy array): Predicted labels.

    Returns:
        float: Binary accuracy.
    """
    return np.mean(np.equal(y_true, np.round(y_pred)))


def framewise_binary_accuracy(y_true, y_pred):
    """
    Computes the framewise binary accuracy between two arrays.

    Args:
        y_true (numpy array): Ground truth labels.
        y_pred (numpy array): Predicted labels.

    Returns:
        float: Framewise binary accuracy.
    """
    return np.mean(np.all(np.equal(y_true, np.round(y_pred)), axis=1))

这两个函数基于numpy库，用于计算二进制准确率和帧间二进制准确率，利用矢量化操作处理数据，以提高计算速度。
