WebApr 10, 2024 · A hard paywall, by nature, must obscure the bulk of an article. Let’s look at a few ways that can be done: An inline paywall is embedded in the page and moves as the user scrolls. In this example from The Economist, they used an inline paywall to obscure the remainder of the article after the first paragraph. WebSpecifically, we train a generator to produce negative examples online. The generator is novel from two perspectives: 1) it is instance-wise which means that the generated examples are based on the input image, and 2) it can generate hard negative examples since it is trained with an adversarial loss.
WebJan 25, 2024 · The first step is to compute the cosine similarity matrix or score in the code. This is \(V_1 V_2^T\) which is generated with fastnp.dot.. The clever arrangement of inputs creates the data needed for positive and negative examples without having to run all pair-wise combinations. Because Q1[n] is a duplicate of only Q2[n], other combinations are … Web(i.e., hard negative examples) as well as intra-class variance (i.e., hard positive examples). In contrast to existing mining-based methods that merely rely on ex-isting examples, we present an alternative approach by generating hard triplets to challenge the ability of feature embedding network correctly distinguishing
