A system develops classifiers that can aid medical professionals by diagnosing whether or not a patient has a medical condition like pneumothorax. The system breaks the task into multiple steps, using YOLOv4 to extract relevant regions of the video and a 3D sparse coding model to represent video features. Given the difficulty in acquiring positive training videos, the inventors trained a small-data classifier with a maximum of 15 positive and 32 negative examples. To counteract this limitation, the inventors leveraged subject matter expert (SME) knowledge to limit the hypothesis space, thus reducing the cost of data collection. The inventors present results using two lung ultrasound datasets and demonstrate that the inventors' model is capable of achieving performance on par with SMEs in pneumothorax identification.

Methods and uses of using Sigma1 inhibitors are provide herein, including diagnostic methods for predicting or identifying quantitatively whether a human tumor is responsive or non-responsive to treatment with Sigma1 inhibition are also provided.

Systems and methods for detecting malware on routers use transformer-based anomaly detection. System call data and network packet data are collected from a router and transformed into vector embeddings using embedding models such as sys2vec or net2vec. The embeddings are processed by a transformer-based encoder, such as a BERT model, trained with contrastive or contrastive adversarial learning using anchor, positive, and negative samples derived from benign behavior. The resulting model distinguishes anomalous activity, including zero-day and network-intensive malware, from benign behavior with low false positive rates. Detection occurs at the router or hub level, reducing computational overhead on resource-constrained Internet of Things (IoT) devices and enabling real-time protection without reliance on cloud-based solutions. By combining system call and network packet anomaly detection, the disclosed approach provides robust, low-latency, and low-overhead defense against a wide range of malware behaviors in router-managed ecosystems.
