See Inside AI Digit Recognition with TensorSpace LeNet

The useful part

TensorSpace LeNet is featured here for one specific job: handwritten digit inference with a 3D intermediate-layer visualization. This guide focuses on that workflow so you can decide whether it fits your task before trying it.

What happened in the demo

Open TensorSpace LeNet and sketch one on the drawing pad. That simple doodle becomes the model’s input. Here’s the result: seven is highlighted, with intermediate layer activity visible in three dimensions. You’re seeing a pretrained neural network make a prediction. Use this free browser playground to make an AI lesson more concrete.

The example used in the reel

A small, specific input makes the result easier to inspect. Use the example below to understand the scope of the recorded workflow; it is not a promise that a new run will produce an identical result.

Draw a seven on the TensorSpace LeNet drawing pad, then inspect the actually highlighted digit prediction and the 3D intermediate layer visualization.

Try it yourself

1. Open the LeNet digit example
2. Inspect the layer visualizations
3. Follow the representation toward the predicted digit

Start with material you own or have permission to use. Save the original and compare it with the output before moving the result into a real project. If the interface has changed, follow the current official instructions linked below.

What to check before using the result

Layer images are a learning aid. They do not make every individual prediction interpretable.

Keep the task narrow on your first attempt. Check the details that matter to your use case rather than judging only whether the result looks polished. A successful short example is a useful introduction, not a benchmark of the whole product.

Access, free demos & limits

Checked 2026-10-27: the official LeNet playground is publicly accessible without an account or payment. TensorSpace is open source under Apache 2.0. This demonstration uses its existing pretrained model; allow time for browser loading. The official guide recommends a medium or large screen.

Availability notes refer to the dated demonstration or source check. Features, limits and sign-in requirements can change. Check the official site before starting a larger project.
