WideResNet101 is a high-performance variant of residual networks, boosting model capacity by significantly increasing network width (channel count) rather than adding layers. Building on ResNet-101, it employs wider residual blocks (e.g., width factors of 2 or 4) to expand feature dimensions for enhanced local detail capture, while maintaining shallower depth to mitigate gradient vanishing. Inheriting residual skip connections and batch normalization, it ensures stable training and fast convergence, achieving higher accuracy than ResNet-101 on datasets like ImageNet. Despite moderate parameter growth, optimized computational efficiency makes it suitable for high-precision tasks (e.g., image classification, object detection), balancing performance and resource constraints.

When the user has fine-tuned the source model, the model conversion process must be performed again.

Users can refer to either of the following two methods to complete the model conversion:

• Using AIMO for model conversion: Click Model Conversion Reference in the Performance Reference section on the right to view the conversion steps.

• Using Qualcomm QNN for model conversion: Please refer to the Qualcomm QNN Documentation.

The model performance benchmarks and example code provided by Model Farm are all implemented based on the APLUX AidLite SDK.

For models in .bin format, you can use either of the following two inference engines to run inference on Qualcomm chips:

Inference using APLUX AidLite: please refer to the APLUX AidLite Developer Documentation

Inference using Qualcomm QNN: Please refer to the Qualcomm QNN Documentation

Inference Example Code
