Short answer

How do I turn logits into probabilities?

Your AI uses the calculate_activation tool to run Sigmoid or Softmax functions on your raw data. This turns unscaled numbers into readable percentages or distributions. You'll see the exact breakdown of how the math works below.

The results you get

Mathematical outcomes

The AI processes your raw arrays into these specific formats.

BINARY

Sigmoid scaling

The AI applies Sigmoid to your values. You get a clean 0 to 1 range for every individual logit.

MULTICLASS

Softmax distributions

The AI runs Softmax on your vector. This gives you a set of probabilities that sum to exactly one.

STABLE

Normalized outputs

The AI handles the exponentiation and normalization. You get stable numbers ready for downstream logic.

HUMAN

Threshold decisions

The AI provides the math, but you decide which probability thresholds actually matter for your specific use case.

The workflow

What your AI does when logits arrive.

The AI acts as a specialized calculator for your model's raw outputs.

  1. Ingest logits

    Your AI client takes the raw numerical arrays or vectors from your model.

    calculate_activation

  2. Select function

    The AI chooses between Sigmoid for independent probabilities or Softmax for mutually exclusive classes.

    calculate_activation

  3. Compute values

    The AI executes the math to transform the raw scores into a normalized range.

    calculate_activation

  4. Return distribution

    The AI delivers the final probability set back to your chat interface.

FAQ

How the math works

  • 01

    Can the AI change my model's weights?

    No. This MCP only performs math on the outputs you provide.

  • 02

    Does it work for multi-label tasks?

    Yes. You can ask the AI to use Sigmoid to get independent probabilities for each label.

  • 03

    Can the AI save these probabilities to a file?

    No. This MCP only calculates the values; you must handle saving the data in your own environment.

  • 04

    Can I use this for any numerical array?

    Yes, as long as the data is provided as a list of numbers for the AI to process.

  • 05

    Does the AI decide which function is better?

    The AI can suggest a function, but you should tell it whether to use Sigmoid or Softmax to get the result you want.
