https://www.selleckchem.com/products/OSI-906.html High-risk nonmelanoma skin cancers of the head and neck may be identified through a variety of tumor risk factors, including location on the lips or ears, size > 2 cm, recurrence, patient immunocompromised status, poor tumor differentiation, > 6 mm thickness, Clark level V depth of invasion, and presence of perineural spread. Surgical excision is the mainstay of treatment, with Mohs' micrographic surgery typically preferred to standard surgical excision. When reconstructing these defects, ensuring negative margins is of utmost importance and delaying reconstruction until confirmation of margins is recommended. Attention to the impact of immunosuppression and adjunct radiation therapy on wound healing is important for an optimal cosmetic outcome. As with all high-risk cancer patients, close follow-up and surveillance of these patients is imperative.Deep networks can learn complex problems, however, they suffer from overfitting. To solve this problem, regularization methods have been proposed that are not adaptable to the dynamic changes in the training process. With a different approach, this paper presents a regularization method based on the Singular Value Decomposition (SVD) that adjusts the learning model adaptively. To this end, the overfitting can be evaluated by condition numbers of the synaptic matrices. When the overfitting is high, the matrices are substituted with their SVD approximations. Some theoretical results are derived to show the performance of this regularization method. It is proved that SVD approximation cannot solve overfitting after several iterations. Thus, a new Tikhonov term is added to the loss function to converge the synaptic weights to the SVD approximation of the best-found results. Following this approach, an Adaptive SVD Regularization (ASR) is proposed to adjust the learning model with respect to the dynamic training characteristics. ASR results are visualized to show how ASR overcom
