2015年12月31日 · You can write svm_model or any easy name at place of of clf for better understanding. ... Need to clarify ...

Using plt.clf() in such case will produce a warning after 20 plots (even if they are not going to be shown by plt.show()): More than 20 figures have been opened. Figures created through the pyplot interface (matplotlib.pyplot.figure) are retained until explicitly closed and …

2023年10月2日 · fig.clf() clears the entire figure. This call is equivalent to plt.clf() only if fig is the current figure. fig.clear() is a synonym for fig.clf() Note that even del fig will not close the associated figure window. As far as I know the only way to close a figure window is using plt.close(fig) as described above.

2019年5月3日 · by default the clf.score uses the mean accuracy (your accuracy score). The metric will depend on the balance of the dataset and your level of acceptance of FP and FN. There is not only one answer. –

2015年8月22日 · I'm build a model clf say . clf = MultinomialNB() clf.fit(x_train, y_train) then I want to see my model accuracy using score. clf.score(x_train, y_train) the result was 0.92. My goal is to test against the test so I use. clf.score(x_test, y_test) This one I got 0.77, so I thought it would give me the result same as this code below

2009年10月12日 · CR and LF are control characters, respectively coded 0x0D (13 decimal) and 0x0A (10 decimal).. They are used to mark a line break in a text file.

clf.predict([30,4000,1]) The model is not able to understand that these are columns of a same row or data of different rows. So you need to convert that into 2-d array, where inner array represents the single row. Do this: clf.predict([[30,4000,1]]) #<== Observe the two square brackets

2022年2月12日 · @Lancdorr, well not always.clf.score() would depend on the metrics you use such as MSE, etc. accuracy_score is simply matching two lists if you will - [a, b, c.. ] to [a', b', c'], each of the item could be a list in itself. I should mention clf.score() would also depend on the class_weight for SVC. So you could get them to be the same in some ...

A typical score metric is like (true_value, predicted value), true value is compared against predicted value so why do we actually say that clf.score(X_test, y_test) which is essentially the syntax of fitting the model. Can you help me by explaining the things occuring under the hood or atleast point me in the direction? –

2009年12月28日 · On a Windows machine, I added some files using git add. I got warnings saying: LF will be replaced by CRLF What are the ramifications of this conversion?
