Title: "Hide-and-Seek: Machine Learning in Encrypted Domain"
Abstract: Machine Learning models were built using a huge amount of high-quality and application-specific data. Even though the machine learning models can only be trained at places where the data is available, anyone can use the trained model for classification tasks via the Internet. While it sounds revolutionary, the trained ML models are not readily available to users in healthcare, finance, or marketing due to privacy issues. Users do not want to share their sensitive data with service providers due to a lack of trust. Simply encrypting the data only protects them during storage and transmission. Researchers and industries are developing novel techniques known as privacy-preserving techniques to process the data in an encrypted domain to tackle the privacy issue. Homomorphic encryption plays a key role in developing privacy-preserving machine learning algorithms. While homomorphic properties exist in traditional cryptographic schemes such as RSA, this talk will focus on fully homomorphic encryption from lattice-based cryptography. We will also go through the state-of-the-art works, challenges and future trend in this domain.

Title: "Advances in Deep Learning"
Abstract: Deep learning has become the key machine learning tool in various AI application areas such as computer vision, natural language processing, and speech recognition. Systems powered by deep learning are already in everyday use; examples are: image and voice recognition software on smartphones, recommendation systems on eCommerce websites, and language translation software. Even more exciting deep-learning-powered systems like self-driving cars are just around the corner.
