Challenging Human Supremacy: Evaluating Monte Carlo Tree Search and Deep Learning for the Trick Taking Card Game Jass

Abstract: Despite the recent successful application of Artificial Intelligence (AI) to games, the performance of cooperative agents in imperfect information games is still far from surpassing humans. Cooperating with teammates whose play-styles are not previously known poses additional challenges to current state-of-the-art algorithms. In the Swiss card game Jass, coordination within the two opposing teams is crucial for winning. Since verbal communication is forbidden, the only way to transmit information within the team is through a player’s play-style. This makes the game a particularly suitable candidate subject to continue the research on AI in cooperation games with hidden information. In this work, we analyse the effectiveness and shortcomings of several state-of-the-art algorithms (Monte Carlo Tree Search (MCTS) variants and Deep Neural Networks (DNNs)) at playing the Jass game.

New Vision Architectures Beyond CNNs

Abstract: Convolutional Neural Networks (CNNs) have been solely dominating the field of computer vision for nearly a decade. In this talk I will present two recent papers that propose new and highly competitive architecture classes for computer vision. In the first part I will present the Vision Transformer model (ViT), which is almost identical to the standard transformer model used in natural language processing, but happens to work surprisingly well for vision applications. In the second part of the talk, I will present the MLP-mixer model: an all-MLP architecture for vision. It can be seen as a simplified ViT model without the self-attention layer. Nevertheless, it also demonstrates strong results across a wide range of vision applications.

Provably efficient machine learning for quantum physics

Abstract: Classical machine learning (ML) provides a potentially powerful approach to solving challenging problems in quantum physics and chemistry. However, the advantages of ML over more traditional methods have not been firmly established. We prove that classical ML algorithms can efficiently predict ground state properties of a physical system, after learning from data obtained by measuring related systems. We also prove that classical ML algorithms can efficiently classify a wide range of quantum phases of matter. Our arguments are based on the concept of a classical shadow, a succinct classical description of a quantum state that can be constructed in feasible quantum experiments and be used to predict many properties of the state.
This is joint work with Robert Huang (Caltech), Giacomo Torlai (AWS), Victor Albert (University of Maryland) and John Preskill (Caltech+AWS).
