Abstract: A two-stage learning framework provides image-based complementary item recommendations. After receiving an image of a real-world scene depicting at least one object, the first stage generates feature embeddings for the real-world scene and the at least one object. The second stage generates a predicted feature embedding for at least one predicted object from the feature embeddings obtained from the first stage, generates a category embedding for the at least one predicted object from the predicted feature embedding, generates a recommended feature embedding for at least one recommended object from the predicted feature embedding and the category embedding, and outputs an identifier of the at least one recommended object, wherein the at least one recommended object is complementary to the at least one object.

Abstract: Techniques for fine-tuning a machine-learned model for reliable retrieval augmented generation are provided. In one technique, a question for a large language model (LLM) is identified. A context data item that is in an incorrect context relative to the question is also identified. The question and the context data item are input into the LLM, resulting in the LLM generating a response. A training instance that comprises the question, the context data item, a deny response as a correct answer, and the response as a rejected answer is generated. A machine-learned model (e.g., the LLM) is fine-tuned based on the training instance.

Abstract: A computing device for verifying data integrity is provided, comprising a memory controller configured to receive a plurality of original data blocks. Each original data block has an associated initial CRC value. The memory controller then segments and recombines the received data blocks into logic blocks, and calculates a new logic block CRC value for each logic block. The logic blocks are transmitted with their respective new logic block CRC values to a storage device, and the logic blocks are written to non-volatile memory of the storage device in a write operation. After the write operation, a combined CRC value is calculated for the logic blocks and a combined CRC value for the original data blocks, and compare the combined CRC values. The memory controller determines whether the combined CRC values match. When they match, the memory controller generates a verification response verifying the integrity of the write operation.
