Google is attempting to let smartphones better recognize images while also reducing the consumption of power. Towards this, the company has introduced a brand new set of models called MobileNets. These are basically pre-trained image recognition models that will allow devs to suit a model for their application based on their specific requirements.
So here is the thing, mobile applications aren’t very good at machine learning. So what they do is that they transmit all the data they have gathered to a cloud service and the processors that actually derive the insights from the data are situated there only. The users are directly presented with the insights through the app.
The advantage of this approach is that you can use massive workstations and computers for deriving insights — allowing you to leverage the kind of processing power that wouldn’t be available with within a mobile. The disadvantage of the approach is latency and of course, your data is no longer private and is vulnerable to attacks.
These issues an be resolved if there was a way to perform computations on the mobile. However, while this is possible thanks to the advanced processing units we have developed, it takes up a lot of battery. More battery in short, than you would be willing to sacrifice. So what needs to be done, is that all processes need to be optimized so that the battery loss is as low as possible.
With MobileNets though, you can leave all that hefty work to Google. The company has taken care of all the optimization before hand and developers can simply implement the model in their application.
These models are available in all sorts of complexity and capabilities and you can chose the one that suits your needs. While choosing the model, you can keep this in mind: the ore the number of operations a model uses, the more accurate it will be. But the strain on the resources will also increase.
You can deploy these models through Tensor Flow Mobile.
