Prediction of Train Station Delay Based on Multiattention Graph Convolution Network

Algorithm 1 Encoding nonnumerical data.

	Input:
	data, encoded row list;
	Output:
	encodeddata;
(1)	Data = read(data);
(2)	ec = OneHotEncoder();
(3)	one hot data = ec.fit transform(encoded row list).to array();
(4)	new dataFrame = DataFrame(one hot data);
(5)	concat result = concat([data, new dataFrame], axis = 1);
(6)	return concat result;
