  • Publication number: 20200408786
    Abstract: A method for rapid and quantitative determination of sildenafil in cocktail includes the exemplary steps of: Step 1, assigning a Raman spectrum of sildenafil; Step 2, weighing and dissolving a sildenafil standard in methanol to obtain a 1,000 mg/L sildenafil standard solution, and mixing cocktails with the sildenafil standard solution, to prepare test solutions; Step 3, mixing 100 ?L each of test solutions with 500 ?L of surface enhancer OTR 202 to acquire Raman spectra; and Step 4, establishing a linear regression model, with a formula of y=4035.1 x+503.26, where y is the content of sildenafil in cocktail, in mg/L, and x is intensity of Raman characteristic peaks at 1584 cm?1. Rapid determination of sildenafil by SERS is feasible and reliable, serving as a novel, rapid, and accurate method for quantitative determination of sildenafil in cocktail. The method meets the requirements of analysis and detection of sildenafil in other alcoholic beverages.

  • Publication number: 20200302019
    Abstract: A system for training and deploying an artificial conversational entity using an artificial intelligence (AI) based communications system is disclosed. The system may comprise a memory storing machine readable instructions. The system may also comprise a processor to execute the machine readable instructions to receive a request via an artificial conversational entity. The processor may also transmit a response to the request based on a dialog tree generated from at least a model-based action generator and a memory-based action generator. The processor may further provide a training option to a user in the event the response is suboptimal. The processor may additionally receive a selection from the user via the training option. The selection may be associated with an optimal response.

  • Patent number: 10580176
    Abstract: Generally discussed herein are devices, systems, and methods for visualization of user intent in accessing a virtual agent. A method can include receiving sentences from the respective interaction sessions, projecting the sentences to a higher-dimensional space to create respective higher-dimensional vectors, projecting the higher-dimensional vectors to a lower-dimensional space to create respective lower-dimensional vectors, the lower-dimensional space including either two dimensions or three dimensions, plotting the lower-dimensional vectors as respective points on a graph, encoding the respective points consistent with the respective intents determined to be associated with the sentences by an intent classifier to create encoded points, and generating a visual representation of the encoded points.

  • Publication number: 20190156220
    Abstract: Systems and methods for machine comprehension are provided. In example embodiments, a machine accesses a context and a question related to the context. The machine determines a low-level meaning of the question and a low-level meaning of the context, the low-level meaning corresponding to words or phrases. The machine determines a high-level meaning of the question and a high-level meaning of the context, the high-level meaning corresponding to sentences or paragraphs. The machine computes, for each position i in the context, a first probability that an answer to the question starts at the position i. The machine computes, for each position j in the context, a second probability that the answer to the question ends at the position j. The machine determines the answer to the question based on the computed first probabilities and the computed second probabilities.
