Hi Krishna,

As you did not provide any information of your data and the network or model you used, I have listed below some general steps that can help you to use your data as calibration data:

Preprocessing the data:

You can use functions like “readtable” or “readmatrix”.Split your data into training, validation, and testing sets. The calibration data for Deep Network Quantizer typically comes from the training set or a subset of it.

data = readmatrix('your_data.csv');

% Assuming 'data' is organized with features along columns and samples along rows

X = data(:, 1:end-1); % Features

Y = data(:, end); % Targets

% Reshape or adjust X and Y to match your network's input and output requirements

Convert your data to MATLAB’s “dlarray ” (for more information on this refer to documentation attached at the end) and create a network

To use the data for calibration in Deep Network Quantizer, you need to create a dlarray:

% Assuming 'calibrationData' (subset of your training data) is your prepared calibration dataset

% and 'net' is your trained network

dlX = dlarray(calibrationData, 'SSCB'); % Example format, adjust 'SSCB' as needed(refer documentation for information on input parameters)

dlnet = dlnetwork(net);

Calibrate

executionEnvironment = 'cpu'; % Choose 'cpu' or 'gpu'

calibrate(dlnet, dlX, executionEnvironment);

Further you may refer to the following documentations to know more details about the used functions.
