Abstract: Provided are systems and methods for the aggregate evaluation of content. In particular, an example content evaluation system can use one or more “assistant evaluators” to generate intermediate score(s) for a content item. The example system can then leverage a machine learning model (e.g., a sequence processing model such as a large language model (LLM) or large multimodal model (LMM)) to generate an aggregate score for a content item from the intermediate score(s).

Abstract: In a method, a plurality of recommended items in a target domain is obtained. A first interaction feature of a sample object in a source domain is fused with a second interaction feature of the sample object in the target domain to obtain a fused interaction feature. Similarity scores between the fused interaction feature and each of the plurality of recommended items are determined. A plurality of hard negative samples (HNSs) is filtered from the plurality of recommended items based on the similarity scores. The plurality of HNSs is combined into a candidate recommended item set. A third interaction feature is fused with a fourth interaction feature to obtain a transfer interaction feature. A plurality of real hard negative samples (RHNSs) is filtered from the plurality of HNSs based on similarity scores between the transfer interaction feature and each of the plurality of HNSs.

Abstract: A native leaflet treatment system and method for treating native heart valve leaflets before heart valve repair or replacement procedure. The treatment system includes a delivery apparatus configured to enter the heart, and a native leaflet treatment device stored in the delivery apparatus in a compressed state. The treatment device includes a clamping structure, which is configured to retain at least a portion of the native leaflets in the deployed state. The treatment device is delivered into the heart using the delivery apparatus, and released near the native heart valve, where the treatment device expands and the clamping structure captures and holds the native leaflet, such that the native leaflets will no longer block blood flow. This improves the dynamics of the blood flow which facilitates subsequent surgical procedures (minimally-invasive surgery or open surgery) for heart valve repair or replacement.
