Fine-tuning a version of Eleuther AI’s model Credit: iLexx on Stock Photos | Electricity Transformer Natural Language Processing (NLP) has been revolutionized by recent research and the release of new transformer-based large language models(LLM) from the likes of OpenAI(GPT-2 and GPT-3), Eleuther AI (GPT-NEO and GPT- J), and Google (BERT, T5, PaLM). Large language models … Read more

tf.keras – Keras Model Classification doesn’t learn in FineTuning

I’m trying to Fine-Tuning EfficientNetB4 to classify 10 classes. First of all, I modify the model as follows: baseModel = EfficientNetB4(weights=”imagenet”, include_top=False, input_tensor=Input(shape=(img_width, img_height, 3))) headModel = baseModel.output headModel = tf.keras.layers.GlobalAveragePooling2D(name=”avg_pool”)(headModel) headModel = tf.keras.layers.BatchNormalization()(headModel) headModel = tf.keras.layers.Dropout(0.2, name=”top_dropout”)(headModel) headModel = Dense(10)(headModel) #10 CLASSES headModel = Activation(‘softmax’)(headModel) Once these modifications, I set all the layers basemodel … Read more
