It seems the task you are trying to solve is regression: predicting the price. However, you are training a classification model, that assigns a class to every input. ROC-AUC score is meant for classification problems where the output is the probability of the input belonging to a class. If you do a multi-class classification, then … Read more
When you say You are implicitly asking Python to convert (a[‘x’]==1) and (a[‘y’]==10) to Boolean values. NumPy arrays (of length greater than 1) and Pandas objects such as Series do not have a Boolean value — in other words, they raise ValueError: The truth value of an array is ambiguous. Use a.empty, a.any() or a.all(). when used as a … Read more
When you call loc with a scalar value, you get a pd.Series. That series will then have one dtype. If you want to see the row as it is in the dataframe, you’ll want to pass an array like indexer to loc. Wrap your index value with an additional pair of square brackets
I am trying to predict economic cycles using Gaussian Naive Bayes “Classifier”. data (input X) : target (output Y) : Below is my code: Below is Error: What am I doing wrong? How can I resolve this issue /error ?
I think the most simple way is .iloc[[0, -1]].
It’s because accuracy_score is for classification tasks only. For regression you should use something different, for example: Where X_test is samples, y_test is corresponding ground truth values. It will compute predictions inside.
I think I would do this with two groupbys. First to calculate the “weighted average”: If you set this as a column, you can groupby over it: Now the sum of this column is the desired: or potentially:
As you can see, the AND operator drops every row in which at least one value equals -1. On the other hand, the OR operator requires both values to be equal to -1 to drop them. That’s right. Remember that you’re writing the condition in terms of what you want to keep, not in terms of … Read more
Simple plot, you can use: Or you can set the index to be Date beforehand, then it’s easy to plot the column you want: If you want a chart with one series by ticker on it You need to groupby before: If you want a chart with individual subplots:
