i want to see precision and recall for my model for a binary image classification but i can find how do to that
Here is my code
x = base_model.output
x = tf.keras.layers.GlobalAveragePooling2D()(x)
x = tf.keras.layers.Dense(1024, activation='relu')(x)
x = tf.keras.layers.Dense(1024, activation='relu')(x)
x = tf.keras.layers.Dense(512, activation='relu')(x)
preds = tf.keras.layers.Dense(2, activation='softmax')(x)
model = tf.keras.Model(inputs = base_model.input, outputs = preds)
for layer in model.layers[:175]:
layer.trainable = False
for layer in model.layers[175:]:
layer.trainable = True
model.compile(optimizer='Adam', loss='categorical_crossentropy', metrics=['accuracy'])
history = model.fit_generator(generator=train_generator,
epochs=20,
steps_per_epoch=step_size_train,
validation_data = test_generator,
validation_steps=step_size_test)```
If you want precision and recall during train then you can add precision and recall metrics to the metrics
list during model compilation as below
model.compile(optimizer='Adam', loss='categorical_crossentropy',
metrics=['accuracy',
tf.keras.metrics.Precision(),
tf.keras.metrics.Recall()])
input = tf.keras.layers.Input(8)
x = tf.keras.layers.Dense(4, activation='relu')(input)
output = tf.keras.layers.Dense(2, activation='softmax')(x)
model = tf.keras.Model(inputs = input, outputs = output)
model.compile(optimizer='Adam', loss='categorical_crossentropy',
metrics=['accuracy',
tf.keras.metrics.Precision(),
tf.keras.metrics.Recall()])
X = np.random.randn(100,8)
y = np.random.randint(0,2, (100, 2))
model.fit(X, y, epochs=10)
