This paper introduces a novel, integrated approach AHA ( A daptive H uman-A ssisted OOD learning) to simultaneously address both OOD generalization and detection through a human-assisted framework by labeling data in the wild.

Modern machine learning models deployed often encounter distribution shifts in real-world applications, manifesting as covariate or semantic out-of-distribution (OOD) shifts. These shifts give rise to challenges in OOD generalization and OOD detection. This paper introduces a novel, integrated approach AHA (Adaptive Human-Assisted OOD learning) to simultaneously address both OOD generalization and detection through a human-assisted framework by labeling data in the wild. Our approach strategically labels examples within a novel maximum disambiguation region, where the number of semantic and covariate OOD data roughly equalizes. By labeling within this region, we can maximally disambiguate the two types of OOD data, thereby maximizing the utility of the fixed labeling budget. Our algorithm first utilizes a noisy binary search algorithm that identifies the maximal disambiguation region with high probability. The algorithm then continues with annotating inside the identified labeling region, reaping the full benefit of human feedback.

Breakthroughs, discoveries, and DIY tips sent every weekday. That euphoric feeling when a great idea strikes or a challenging puzzle piece fits into place is electric–and also helps our brains. Now, a team of researchers from the United States and Germany have taken a peek inside the brain to see what those so-called aha, lightbulb, or eureka moments look like. The new brain imaging shows that these flashes of insights reshape how the brain represents information and helps burn it into our memory. According to Maxi Becker, a study co-author and cognitive neuroscientist at Humboldt University in Berlin, if you have one of these aha moments when solving a problem, "you're actually more likely to remember the solution.'" The findings are detailed in a study published May 9 in the journal Nature Communications.

The algorithm then continues with annotating inside the identified labeling region, reaping the full benefit of human feedback. Extensive experiments validate the efficacy of our framework. We observed that with only a few hundred human annotations, our method significantly outperforms existing state-of-the-art methods that do not involve human assistance, in both OOD generalization and OOD detection.

LLMs (large language models) like ChatGPT are of such high capability – or threat – that we can forget to think about how they are achieving such near supernatural generative abilities. 'Oh, LLMs have just learned advanced word statistics'

Standard few-shot experiments involve learning to efficiently match previously unseen samples by class. We claim that few-shot learning should be long term, assimilating knowledge for the future, without forgetting previous concepts. In the mammalian brain, the hippocampus is understood to play a significant role in this process, by learning rapidly and consolidating knowledge to the neocortex over a short term period. In this research we tested whether an artificial hippocampal algorithm, AHA, could be used with a conventional ML model analogous to the neocortex, to achieve one-shot learning both short and long term. The results demonstrated that with the addition of AHA, the system could learn in one-shot and consolidate the knowledge for the long term without catastrophic forgetting. This study is one of the first examples of using a CLS model of hippocampus to consolidate memories, and it constitutes a step toward few-shot continual learning.

As the world continues to battle Covid-19, its effects on population health are just one facet of the crisis. The economic fallout is also seriously impacting both people and businesses, including hospitals and other healthcare facilities. The American Hospital Association (AHA) estimates the country's hospitals and health systems could lose $120.5 billion between July and December 2020. This is in addition to AHA's previous financial impact estimate -- losses of $202.6 billion between March and June 2020 -- bringing total losses for the calendar year to at least $323 billion. Half of all hospitals could be operating in the red during the second half of 2020, according to analysis prepared by Kaufman Hall and released by the AHA.
