AI isn’t just for JavaScript and Python anymore. Using Deeplearning4J, we’ll train a neural network in Java, and with MongoDB, we’ll manage and store transaction data efficiently. Given a whole host of data on customer transactions, we are going to teach or model how to spot the ...
Harmonic Mean (HM): You can calculate the harmonic mean of a series of numbers dividing the total number of elements by the sum of the inverse of each number in the sequence. Hence, the harmonic mean can be calculated using the formula given below: ...
F1-score: The F1-score is the harmonic mean of precision and recall. It tries to find the balance between both measures. It is a more reliable metric than accuracy when dealing with imbalanced classes. In our case, we had slightly imbalanced classes, so it’s a good idea to che...
The formula for calculating the harmonic mean in the B21 cell is: =HARMEAN(C5:C17) Here, the range of cells C5:C17 represents the cells of the Average Marks column. One thing is clear: the value of the harmonic mean, in this case, is lower than the average value of the Average Mar...
(harmonic mean of precision and recall) f1 = 2 * p * r / (p + r + eps) names = [v for k, v in names.items() if k in unique_classes] # list: only classes that have data names = dict(enumerate(names)) # to dict if plot: plot_pr_curve(px, py, ap, Path(save_dir) ...
Although suggestive, these proposals have several limitations. The main issue is that the “subject categories” are often too wide and they do not allow to compare correctly articles and authors. For instance in the subject category “mathematics,” we can find disciplines which have very differen...
What Does ‘Does Not Name a Type’ Mean? The ‘does not name a type’ error is an indication from the Arduino IDE that it was unable to find a definition for something that you’re trying to use. The most common cause of this error is when you are trying to declare or use a vari...
Generative Adversarial Networks (GAN) show excellent performance in various problems of computer vision, computer graphics, and machine learning, but requi
