Kuchlous, Sahil, Kadaba, Madhura.  2020.  Short Text Intent Classification for Conversational Agents. 2020 IEEE 17th India Council International Conference (INDICON). :1–4.
Intent classification is an important and relevant area of research in artificial intelligence and machine learning, with applications ranging from marketing and product design to intelligent communication. This paper explores the performance of various models and techniques for short text intent classification in the context of chatbots. The problem was explored for use within the mental wellness and therapy chatbot application, Wysa, to give improved responses to free-text user input. The authors looked at classifying text samples in-to 4 categories - assertions, refutations, clarifiers and transitions. For this, the suitability of the following techniques was evaluated: count vectors, TF-IDF, sentence embeddings and n-grams, as well as modifications of the same. Each technique was used to train a number of state-of-the-art classifiers, and the results have been compiled and presented. This is the first documented implementation of Arora's modification to sentence embeddings for real world use. It also introduces a technique to generate custom stop words that gave a significant gain in performance (10 percentage points). The best pipeline, using these techniques together, gave an accuracy of 95 percent.

Researchers develop bioassays by rigorously experimenting in the lab. This involves significant fiscal and skilled person-hour investment. A competitor can reverse engineer a bioassay implementation by imaging or taking a video of a biochip when in use. Thus, there is a need to protect the intellectual property (IP) rights of the bioassay developer. We introduce a novel 3D multilayer-based obfuscation to protect a biochip against reverse engineering.

Hu, Yayun, Li, Dongfang.  2019.  Formal Verification Technology for Asynchronous Communication Protocol. 2019 IEEE 19th International Conference on Software Quality, Reliability and Security Companion (QRS-C). :482-486.

For aerospace FPGA software products, traditional simulation method faces severe challenges to verify product requirements under complicated scenarios. Given the increasing maturity of formal verification technology, this method can significantly improve verification work efficiency and product design quality, by expanding coverage on those "blind spots" in product design which were not easily identified previously. Taking UART communication as an example, this paper proposes several critical points to use formal verification for asynchronous communication protocol. Experiments and practices indicate that formal verification for asynchronous communication protocol can effectively reduce the time required, ensure a complete verification process and more importantly, achieve more accurate and intuitive results.

Kannavara, R., Vangore, J., Roberts, W., Lindholm, M., Shrivastav, P..  2018.  Automating Threat Intelligence for SDL. 2018 IEEE Cybersecurity Development (SecDev). :137–137.
Threat intelligence is very important in order to execute a well-informed Security Development Lifecycle (SDL). Although there are many readily available solutions supporting tactical threat intelligence focusing on enterprise Information Technology (IT) infrastructure, the lack of threat intelligence solutions focusing on SDL is a known gap which is acknowledged by the security community. To address this shortcoming, we present a solution to automate the process of mining open source threat information sources to deliver product specific threat indicators designed to strategically inform the SDL while continuously monitoring for disclosures of relevant potential vulnerabilities during product design, development, and beyond deployment.
