MobileNet-v2 is an efficient deep convolutional neural network designed for mobile and embedded devices. It improves upon MobileNet-v1 by introducing an inverted residual structure and a linear bottleneck design. The inverted residuals enable efficient computation by retaining low-dimensional features, while the linear bottleneck reduces the transmission of redundant information, lowering computational costs. MobileNet-v2 achieves significant reductions in model parameters and computational overhead without sacrificing accuracy, making it suitable for environments with limited resources. It is widely used in tasks such as image classification, object detection, and semantic segmentation.

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

The inference example code is implemented using the AidLite SDK.
