Question

我正在尝试对数据进行拟合/训练以使其具有一定的前提条件，但是当我将file.csv更改为自己的数据集时，这是行不通的，假设lesson_test和我的数据具有相同的范围列和类型（日期除外）。（Neural Network to Predict Stock Markets）。

我试图看看发生了什么，我发现我的训练和测试变量与实际值相差太远了。

# fix random seed for reproducibility
np.random.seed(1)

# load the dataset
df.drop(columns=['High', 'Low', 'Close', 'Volume', 'Adj Close'], inplace = True)
data = df.values
data = data.astype('float32')

# normalize the dataset
scaler = MinMaxScaler(feature_range=(0, 1))
dataset = scaler.fit_transform(data)

# split into train and test sets
train = dataset[0:int(np.around(len(data)*0.7)), :]
test = dataset[int(np.around(len(data)*0.7)):, :]

# reshape into X=t and Y=t+1
lags = 3
X_train, y_train = prepare_data(train, lags)
X_test, y_test = prepare_data(test, lags)

# reshape input to be [samples, time steps, features]
X_train = np.reshape(X_train, (X_train.shape[0], 1, X_train.shape[1]))
X_test = np.reshape(X_test, (X_test.shape[0], 1, X_test.shape[1]))

# create and fit the LSTM network
mdl = Sequential()
mdl.add(LSTM(300, activation='softmax', recurrent_activation='relu', input_shape=(1, lags)))
mdl.add(Dense(1, activation='linear'))
mdl.compile(loss='mean_squared_error', optimizer='adam')
history = mdl.fit(X_train, y_train, validation_data=(X_test, y_test), epochs=33, batch_size=100, verbose=2)

# make predictions
train_predict = mdl.predict(X_train)
test_predict = mdl.predict(X_test)

# invert transformation
train_predict = scaler.inverse_transform(train_predict)
y_train = scaler.inverse_transform([y_train])
test_predict = scaler.inverse_transform(test_predict)
y_test = scaler.inverse_transform([y_test])
train_predict

# calculate root mean squared error
train_score = math.sqrt(mean_squared_error(y_train[0], train_predict[:,0]))
print('Train Score: {:.2f} RMSE'.format(train_score))
test_score = math.sqrt(mean_squared_error(y_test[0], test_predict[:,0]))
print('Test Score: {:.2f} RMSE'.format(test_score))

这是我的数据集（问题在这里）：

Date,Open,High,Low,Close,Adj Close,Volume
09:00,3851.50,3853.00,3849.50,3850.00,3.851.00,3776
09:01,3850.50,3851.00,3844.50,3846.50,3.848.13,8664
09:02,3846.50,3847.50,3839.00,3841.50,3.843.63,7520
09:03,3841.50,3842.00,3836.50,3840.50,3.840.13,10174
09:04,3840.00,3842.00,3837.00,3837.00,3.839.00,4649
09:05,3837.50,3841.00,3837.00,3837.50,3.838.25,5225

这是课程数据集：

Result with my data

你们能帮我吗？
