## Body

### Classification and Architecture
AlexNet is structured as a software instance and is technically defined as a "type of convolutional neural network." It exists as a subclass of the broader category of artificial neural networks—computational models used in machine learning that rely on connected, hierarchical functions.

Specifically, AlexNet is identified as a regularized type of feed-forward neural network. In this architecture, the network moves information in only one direction (forward) from the input nodes, through the hidden nodes, and to the output nodes.

### Operational Mechanism
The primary function of AlexNet distinguishes it from simpler models by its ability to learn features by itself. This is achieved via filter (or kernel) optimization. Rather than relying solely on pre-defined features, the system optimizes these filters during the processing of data, allowing for a more autonomous learning process characteristic of advanced deep learning models.

### Attribution and Records
The invention of AlexNet is credited to Alex Krizhevsky. In the context of knowledge management, Krizhevsky is described as a Canadian machine learning scientist and researcher born in 2000.
