❓ Frequently Asked Questions
What is neural network architecture?
The arrangement of layers, types of connections, and the data flow in a neural network, which defines how it processes information.
What are common neural network layer types?
Dense (fully connected), convolutional, pooling, and recurrent layers are typical building blocks used to transform data.
What is the difference between feedforward and recurrent architectures?
Feedforward networks move information in one direction with no cycles, while recurrent networks include loops that let information persist over time.
What are residual connections and why are they used?
Residual connections are shortcuts that add input to a layer's output, improving gradient flow and enabling training of deeper networks.
What is a Transformer architecture?
A design that uses self-attention to model relationships between elements in a sequence, without relying on recurrence, and is popular in NLP.
