| Factors Affecting Performance [Text Block] | What factors influenced performance? The Roundhill Generative AI & Technology ETF is an actively managed exchange-traded fund that seeks to achieve its investment objective by investing in the equity securities of exchange-listed companies globally, including those in emerging markets, which are involved in the investment theme of artificial intelligence (“AI”), focused on generative AI and related technologies. AI refers to computer simulation of human intelligence in computers that are programmed to think and learn like humans. It is a branch of computer science that deals with the creation of intelligent machines that work and react like humans. Some of the key techniques used in AI include:
• machine learning - learning a new task without being specifically programmed to do it, • deep learning - learning by example, • natural language processing - understanding human language text or speech, • computer vision - interpreting and understanding the visual world (e.g., distinguishing faces), and • expert systems - which simulate the judgment and behavior of humans with expertise in a particular field (e.g., medicine).
AI has a wide range of applications, such as self-driving cars, speech recognition, image recognition, natural language understanding, decision-making, and many more. With the advancement of technology and the increasing amount of data available, AI is becoming increasingly important in many industries. |
