Moku Neural Network
The only FPGA-based neural network integrated into a full suite of test and measurement instruments. Run real-time, powerful machine learning algorithms in line with your experimental setups. Build and train models using Python, then deploy to your test systems using Moku:Delta or Moku:Pro to achieve low-latency inference and react quickly to changing experimental conditions.
Neural network examples
How to build a neural network
First, download Python and install Keras for Tensorflow. Build and train your network on data captured from your Moku or from simulation. Once you're happy with your model performance, upload the weights and biases to your Moku for low-latency inference.
Signal autoencoder
Use the Moku Python API to generate noisy data using your Moku device. Next, train your network on the data. Then use the Moku Neural Network to filter dynamic and unpredictable noise out of an input signal.
Signal classification
This is one of the most common neural network applications. Input data is mapped to a probability distribution across different classes. Build complex pass/fail criteria in your test, react quickly to changing experimental conditions, or catalog and track the occurrence of expected or anomalous waveforms.
Quadrant photodiode sensing
Precisely measure beam position on your quadrant photodiode (QPD) with minimal calibration. Learn and correct for lens distortions and misalignments in real time, with low latency that won't affect your controller stability. Training data can be generated and captured with your Moku, or built from simulations of your optical setup.

FAQ
A neural network is a machine learning structure inspired by the human brain. It consists of interconnected units called neurons, grouped together in layers: an input layer, one or more hidden (internal) layers, and an output layer. In a fully connected model like the Moku Neural Network, each neuron has a series of weights indicating how much the value or any neuron in the previous layer affects its output. These weights are adjusted during a “training” phase so the values at the output layer match a known set of corresponding inputs. After training, the model can be used for “inference,” to infer a set of output values given some inputs that it may or may not have seen before.
Neural networks are typically built and run on combinations of CPUs and/or GPUs. This approach gives incredible co mputing power, but it is also resource-intensive. Large AI models are energy hungry and often excessive for many types of signal processing applications. The flexibility and real-time processing of FPGAs makes them strong candidates for implementing small-scale neural networks. Their parallel processing capabilities benefit the linear algebra and other complex mathematics involved in the propagation of information through the network.
To train a model for the Moku Neural Network, follow this example. It walks you through how to configure your model, generate training data, train the model, and export the resulting weights and biases as a .linn model to be uploaded to the Moku Neural Network.
Not at all — this versatile instrument is engineered to be accessible to all researchers. While machine learning experts can take Moku Neural Network applications to the next level, it’s easy for all Moku:Delta or Moku:Pro users to set up a neural network.
