 ## Model Architecture
 
-The model architecture is based on the Unet++. Unet++ represents a complete convolutional neural network designed for semantic segmentation of images. It comprises both an encoder and a decoder, linked through skip connections. The encoder captures features with varying spatial resolutions (utilizing skip connections), which the decoder leverages to create precise segmentation masks. Notably, the decoder within Unet++ possesses greater complexity compared to the standard Unet model.

-The MobileNetV2 architecture serves as the encoder for our model. During the inference phase, the encoder produces five sets of feature map tensors, each corresponding to distinct depths of encoding. Subsequent feature map tensors exhibit a reduction of spatial dimensions by a factor of two compared to their preceding counterparts. For instance, a tensor generated at depth 0 will possess dimensions [(batch_size, num_channels, height, width)], while a tensor generated at depth 1 will exhibit dimensions [(batch_size, num_channels, height / 2, width / 2)].

 ## Dataset
 
+Importantly, no Worldcoin user data was used to train or fine-tune the IRIS pipeline. Rather, a research dataset from the University of Notre Dame du Lac (ND-IRIS-0405) [4] was used, with the University’s permission. This dataset was enhanced with manual labels, which themselves may be made available for research purposes.
+
 The experimental dataset contained a total of 9 957 manually annotated IR images comming from 676 different people. All images were captured using LG 4000 device. Table below presents dataset split used during training semantic segmentation model.
