下面的代码是工作的。
import numpy as np
import shap
from tensorflow import keras
X = np.array([[(1,2,3,3,1),(3,2,1,3,2),(3,2,2,3,3),(2,2,1,1,2),(2,1,1,1,1)],
[(4,5,6,4,4),(5,6,4,3,2),(5,5,6,1,3),(3,3,3,2,2),(2,3,3,2,1)],
[(7,8,9,4,7),(7,7,6,7,8),(5,8,7,8,8),(6,7,6,7,8),(5,7,6,6,6)],
[(7,8,9,8,6),(6,6,7,8,6),(8,7,8,8,8),(8,6,7,8,7),(8,6,7,8,8)],
[(4,5,6,5,5),(5,5,5,6,4),(6,5,5,5,6),(4,4,3,3,3),(5,5,4,4,5)],
[(4,5,6,5,5),(5,5,5,6,4),(6,5,5,5,6),(4,4,3,3,3),(5,5,4,4,5)],
[(1,2,3,3,1),(3,2,1,3,2),(3,2,2,3,3),(2,2,1,1,2),(2,1,1,1,1)]])
y = np.array([0, 1, 2, 2, 1, 1, 0])
# Updated model with correct input shape
model = keras.Sequential([
keras.layers.LSTM(128, return_sequences=True, input_shape=(5, 5)), # LSTM layer with return sequences
keras.layers.LSTM(128, return_sequences=False), # Another LSTM layer
keras.layers.Flatten(),
keras.layers.Dense(128, activation='relu'),
keras.layers.Dense(3, activation='softmax') # 3 output classes
])
model.compile(optimizer='adam', loss='sparse_categorical_crossentropy', metrics=['accuracy'])
# Train the model
model.fit(X, y, epochs=10)
# Use GradientExplainer with the model itself
explainer = shap.GradientExplainer(model, X)
shap_values = explainer.shap_values(X)
print(shap_values)
字符串
我想显示一个SHAP
值的漂亮图。
我尝试了下面的代码行shap.summary_plot(shap_values, X, feature_names=['Feature 1', 'Feature 2', 'Feature 3', 'Feature 4', 'Feature 5'])
,但不工作

使用您的LSTM模型,指定您想要解释的类和数据点,您将满足数据形状的
summary_plot
期望,即:字符串
的数据
