Getting insights with Computer Vision using AI Insights
The easiest way to analyze images in Power BI is by using the Computer Vision model provided to us through the AI Insights feature in Power BI. The AI Insights feature in Power BI does exactly the same as the Computer Vision API from Azure's Cognitive Services.
When we use a pretrained Computer Vision model such as the one offered by Cognitive Services and AI Insights, we don't have to provide any training dataset and can use the model to analyze our images.
Using a pretrained model brings with it advantages and disadvantages. As already discussed in Chapter 7, Using Cognitive Services, the purpose of these pretrained models is to reduce the time and expertise needed by someone such as you to apply them. However, pretrained models are often trained on a generic dataset, which makes them applicable to many different situations.
It may be of course that for your specific use case, using a pretrained model doesn...
