  • Patent number: 12462104
    Abstract: This application relates to apparatus and methods for natural language understanding in conversational systems using machine learning processes. In some examples, a computing device receives a request that identifies textual data. The computing device applies a natural language model to the textual data to generate first embeddings. In some examples, the natural language model is trained on retail data, such as item descriptions and chat session data. The computing device also applies a dependency based model to the textual data to generate second embeddings. Further, the computing device concatenates the first and second embeddings, and applies an intent and entity classifier to the concatenated embeddings to determine entities, and an intent, for the request. The computing device may generate a response to the request based on the determined intent and entities.

  • Publication number: 20250245913
    Abstract: A system including a processor and a non-transitory computer-readable media storing computing instructions that, when executed on the processor, cause the processor to perform certain operations. The operations can include identifying a 2D silo image of a geometric item based on a probability value exceeding a predetermined probability threshold. The operations also can include segmenting artifacts from the 2D silo image to isolate first pixels of a border of the geometric item. The operations further can include trimming second pixels along the border of the geometric item. The operations also can include performing an aspect ratio validation on the 2D silo image to validate that the 2D silo image corresponds to a shape of the geometric item. The operations additionally can include auto-validating that a visual resolution level of the 2D silo image falls within a predetermined acceptance rate.

  • Publication number: 20240255285
    Abstract: In various embodiments, systems and methods for augmented reality guidance are disclosed. A first position of a local device and a second position of a first item within a predetermined locale are determined. Route data from the first position to the second position is generated and a position of the local device is tracked. In response to the position of the local device being within a predetermined distance of the second position, an image capture element of the local device is activated. Image data is received. When the first item is within the image data, an item highlighter indicating a position of the first item within the image data is generated and when the first item is not within the image data, a direction indicator indicating a position of the first item relative to a field of view of the image data is generated.
