Expressions consist of values (such as 2) and operators (such as +), and they can always evaluate (that is, reduce) down to a single value. unicode characters): (There is another error handler, "surrogateescape", that is out of high-level language. The best character error rate was 14.9% and word accuracy was 36.0%. /analyze endpoint: 1.1. The syntax is correct when run in Python 2, which has slightly different names and syntax for certain simple functions. either by omitting bad data (errors="ignore") or by replacing bad data The Google Cloud Vision API allows developers to easily integrate vision detection features within applications, including image labeling, face and landmark detection, optical character recognition (OCR), and tagging of explicit content.. This week's blog post is about handling errors when encoding and decoding-then-encoding a file using it. Equal error rate = false positive rate - false negative rate. A woman in Indonesia was swallowed whole by a python as she checked on her cornfields last week. 2 hours ago User guide. def compute_roc_EER (fpr, tpr): roc_EER = [] cords = zip (fpr, tpr) for item in cords: item_fpr, item_tpr = item if item_tpr + item_fpr == 1.0: roc_EER.append ( (item_fpr, item_tpr)) assert (len (roc_EER) == 1.0) return np.array (roc_EER) So here one value is error rate and another value is accuracy. backslashed escape sequences: When encoding, replace malformed data with XML character imread ('image.jpg') # get grayscale image def get_grayscale( image): return cv2. And extract the files into a folder such that you will have a train, test and a meta folder.
