The paper proposes a deep learning architecture called AlexNet. This architecture consists of 5 convolutional layers and 3 fully connected layers. Each convolutional layer uses kernels of various sizes, and Rectified Linear Unit (ReLU) is adopted as the activation function. Optimized for image classification tasks, the architecture extracts and classifies image features by alternating between convolution and pooling layers.
To reduce overfitting and enhance the model's generalization ability, data augmentation techniques are employed. Data augmentation artificially expands the training dataset by applying transformations (e.g., rotation, resizing, flipping) to images. These transformations assist the model in learning various visual features.
Dropout techniques are utilized to prevent overfitting. Dropout randomly deactivates selected neurons during training, reducing the complexity of the model and improving its generalization ability.
GPU (Graphics Processing Unit) acceleration is leveraged to train the model quickly. GPUs, with parallel processing capabilities, significantly enhance the training speed of deep learning models.
For initializing the weights of the trained model, values randomly selected from a normal distribution with a mean of 0 and a standard deviation of 0.01 are used. This initialization helps the model quickly receive initial feedback when starting training.
To confirm the importance of model depth, the study verified that the model, including all convolutional layers, achieves the best performance. Removing any layer results in performance degradation, confirming that the depth of deep learning models is crucial in image classification tasks.
