Educational scientific illustration of a Step Activation Function used in a perceptron neural network. Show a clean 2D graph with axes labeled input (x) and output (y). The graph displays a sharp step function: output is 0 for negative inputs and jumps abruptly to 1 at threshold zero (or a clear threshold point). Include a simple visual of a perceptron neuron on the side with weighted inputs feeding into a summation node and an activation function. Style: minimalistic, modern infographic, white background, colored lines (blue or black for graph, red highlight for threshold). Add subtle annotations like ‘threshold’, ‘binary output’, and ‘step activation’. Educational, textbook-quality diagram, high clarity, no clutter. Mehr sehen
