A horizontal illustration in the signature hand-drawn cutaway style of Stephen Biesty, visualizing a two-layer neural network as a massive and extraordinarily complex industrial processing factory. The layout is horizontal, presenting the physical data-processing flow from left to right. The art style is rendered in extremely fine black-and-white pen linework, supplemented with vintage light watercolor washes, revealing architectural and mechanical interior cross-sections brimming with dense, microscopic details.
At the very top of the image, a large title in a vintage serif typeface reads 'TWO-LAYER NEURAL NETWORK'.
On the left side of the image is the "Input Layer," depicted as four towering feed silos constructed from a hybrid of brick masonry and cast iron. The outer walls of the silos are cut away to expose internal spiral conveyors and crushers. Numerous tiny workers push minecarts, tipping glowing blue crystal ore (representing raw data) into hoppers at the top. Slender black leader lines connect to these structures with annotation text reading: 'Input Data Sorter', 'Input 1', 'Input 2', 'Input 3', 'Input 4'.
At the center of the image is the "Hidden Layer," composed of five enormous spherical processing boilers with intricately complex internal structures, arranged side by side. From the four input silos on the left, a dense, spider-web-like tangle of brass pipes extends outward, ensuring that every silo has a pipe connecting to each and every one of the central boilers (visualizing the fully connected layer). The pipes are fitted with large hand-wheel regulating valves. The boilers are cut away to reveal multiple layers of gears, agitator shafts, and glowing red steam combustion chambers at the bottom (visualizing the activation function). Hundreds of tiny workers in blue overalls move about on complex metal scaffolding, staircases, and catwalks—some are collaboratively turning heavy brass valves (representing weight adjustment), others are reading instrument panels, and one worker is sitting on a suspended steel beam drinking coffee on a break. Leader-line annotations in this area include: 'Synaptic Weight Valve', 'Hidden Layer Chamber', 'Bias Input Pump', 'Activation Function Generator'.
On the right side of the image is the "Output Layer," containing two towering precision distillation columns. Thick pipes extending from the five hidden-layer boilers at the center—
