Mavzu: sun'iy neyron tarmoq modeli mashinali o’qitish fanidan

. Neyon tarmoqni o’qitish paramertlarini(o’qish qadami-lr, o’qitishlar soni-epoch) tanlang.
optimizer = Adam(learning_rate=0.001)
model.compile(optimizer, loss='categorical_crossentropy', metrics=['accuracy'])
history = model.fit(train_x, train_y, verbose=2, batch_size=5, epochs=200)


Neyron tarmoqning o’qitish natijalarini garfik tarvirlang.
Grafikda tasvirlab ko’ramiz.

Model aniqligini hisoblang(o’rgatuvchi tanalama uchun).

Modelni test to’plam bilan testlang. Modelini test to’plamdagi aniqligini hisoblang.
