问题 I have a very simple machine learning code here: # load dataset dataframe = pandas.read_csv("USDJPY,5.csv", header=None) dataset = dataframe.values X = dataset[:,0:59] Y = dataset[:,59] #fit Dense Keras model model.fit(X, Y, validation_data=(x,y_test), epochs=150, batch_size=10) My X values are 59 features with the 60th column being my Y value, a simple 1 or 0 classification label.

问题 I have a dataset wherein I have account number and "days past due" with every observation. For every account number, as soon as the "days past due" column hits a code like "DLQ3", I want to remove rest of the rows for that account (even if DLQ3 is the first observation for that account). My dataset looks like: Obs_month Acc_No OS_Bal Days_past_due 201005 2000000031 3572.68 NORM 201006 2000000031 4036.78 NORM 200810 2000000049 39741.97 NORM 200811 2000000049 38437.54 DLQ3 200812 2000000049

问题 Apologies if there does in fact exist a thread that has already figured this out (I've spent a few hours attentively searching multiple sites and the GitHubs for the dependencies that seem to cause the problems), however each solution seemed fairly specific to the particular library that so and so was attempting to use. I've been messing around with quantitative finance/ algorithmic trading and have been trying to import a particular library ffn , however, per the question title, I've been

问题 I would like to generate a 1 min spaced time sequence to paste then to a xts object.
