Intelligent online personal assistant with offline visual search database

A system, comprising:

• at least one processor;
• and
• at least one memory including instructions that, upon execution by the at least one processor, cause the system to perform operations comprising:
• receiving, via a graphical user interface, an input query image;
• processing, by a neural network, the input query image to generate a list of candidate products based on knowledge graph data and a visual similarity measure indicating respective correlations between a plurality of candidate product images and the input query image, the knowledge graph data used to confirm the respective correlations between the plurality of candidate product images and the input query image;
• and
• outputting, for display at the graphical user interface, at least one candidate product from the list of candidate products.

One or more non-transitory computer-readable medium storing instructions executable by at least one processor to cause the at least one processor to perform operations comprising:

• receiving, via a graphical user interface, an input query image;
• processing, by a neural network, the input query image to generate a list of candidate products based on knowledge graph data and a visual similarity measure indicating respective correlations between a plurality of candidate product images and the input query image, the knowledge graph data used to confirm the respective correlations between the plurality of candidate product images and the input query image;
• and
• outputting, for display at the graphical user interface, at least one candidate product from the list of candidate products.
