👉 Layer engineering in neural networks refers to the strategic design and arrangement of different types of layers within a network architecture to optimize its performance, efficiency, and ability to learn complex patterns. This involves selecting appropriate layer types (such as convolutional, recurrent, or fully connected layers) and configuring their parameters (like number of units, activation functions, and connections) to suit the specific task at hand, be it image recognition, natural language processing, or time-series prediction. By carefully engineering these layers, researchers and practitioners can enhance the model's capacity to capture intricate relationships in data, improve generalization, and reduce computational costs, ultimately leading to more robust and accurate AI systems.
