What Happened in Reinforcement Learning in 2022

Just like how we learn from our environment and our actions determine whether we are rewarded or punished, so do reinforcement learning agents whose ultimate aim is to maximise the rewards. This article brings the top 8 reinforcement learning innovations that shaped AI across several industries in 2022. Alphabet's DeepMind collaborated with the University of Venice, the University of Oxford and the Athens University of Economics and Business to build a deep neural network called'Ithaca', which can restore missing text from ancient texts. In a paper published in Nature, DeepMind stated that Ithaca was trained using natural language processing (NLP) to not only recover lost ancient text that has been damaged over time but also identify the original location of the text and establish the date when it was made. With DeepMind's latest release AlphaTensor, an AI system (based on a 3D board game), researchers shed light on a 50-year-old fundamental mathematics question of finding the fastest way to multiply two matrices.
