Publication number: 20240143921Abstract: Techniques are described for training and/or utilizing sub-agent machine learning models to generate candidate dialog responses. In various implementations, a user-facing dialog agent (202, 302), or another component on its behalf, selects one of the candidate responses which is closest to user defined global priority objectives (318). Global priority objectives can include values (306) for a variety of dialog features such as emotion, confusion, objective-relatedness, personality, verbosity, etc. In various implementations, each machine learning model includes an encoder portion and a decoder portion. Each encoder portion and decoder portion can be a recurrent neural network (RNN) model, such as a RNN model that includes at least one memory layer, such as a long short-term memory (LSTM) layer.Type: ApplicationFiled: January 4, 2024Publication date: May 2, 2024Inventors: Vivek Varma DATLA, Sheikh Sadid AL HASAN, Aaditya PRAKASH, Oladimeji Feyisetan FARRI, Tilak Raj ARORA, Junyi LIU, Ashequl QADIR

Patent number: 8435975Abstract: The present invention relates to steroidal esters of 17-oximino-5-androsten-3-ol, of compound of general formula (A) wherein R is selected from a group consisting of arylalkyl, aryl, substituted aryl. The ester derivatives are synthesized starting from Dehydroandrosterone acetate. The compounds were tested for their antiproliferative activity and 5?-reductase inhibitory activity in comparison to Finasteride. Decreased androgen level have been found in serum of animal treated with newly synthesized compounds. These compounds have also shown better cytotoxicity in comparison to reference drug Finasteride. Thus such compounds can be useful in treatment of androgen dependent disorder of prostate alone or by synergistic effect they can decrease the size of prostate due to their antiproliferative activity.Type: GrantFiled: August 14, 2008Date of Patent: May 7, 2013Assignee: Council of Scientific & Industrial ResearchInventors: Tilak Raj Bhardwaj, Manoj Kumar, Neelima Dhingra, Neraj Mehta
