Neural Nets via Forward State Transformation and Backward Loss Transformation

This article studies (multilayer perceptron) neural networks with an emphasis on the transformations involved --- both forward and backward --- in order to develop a semantical/logical perspective that is in line with standard program semantics. The common two-pass neural network training algorithms make this viewpoint particularly fitting. In the forward direction, neural networks act as state transformers. In the reverse direction, however, neural networks change losses of outputs to losses of inputs, thereby acting like a (real-valued) predicate transformer. In this way, backpropagation is functorial by construction, as shown earlier in recent other work. We illustrate this perspective by training a simple instance of a neural network

Partial Preparation of 1-Anilino-8-(Mercaptoamino)-1,8-Octadione as a Potential Therapeutic Agent for the Treatment of Huntington’s Disease and Selected Cancers

We are proposing 1-anilino-8-(mercaptoamino)-1,8-octadione as a compound of potential pharmaceutical value. The addition of carbon disulfide to sodium trimethylsilanolate to yield a xanthate product has been analyzed and refined to a 70% yield. Several methods of aminating the xanthate product to yield a sulfenamide have been attempted and analyzed. Multiple attempts have been made to benzoylate the sulfenamide product with little success, with many concerns stemming from the unsuccessful amination reactions

Scheduling for client-driven capacitated systems

Client-driven, capacitated systems have special characteristics that pose a unique challenge for those attempting to schedule and control such systems. The variable nature of client requirements, the prioritization of clients, limited resource availability, parallel tracks for projects, and stochastic nature of project activities all contribute to the unique nature of these types of systems. Using information gathered from representative systems, we first show how these stochastic, client-driven, capacitated systems can be modeled. Furthermore, these models can be used for real-time scheduling of project activities using a Bayesian approach and an objective function that targets project revenue. We conclude with an illustrative application demonstrating model components and capabilities
