In e - commerce operations, we face many challenges in improving user conversion rates. For example, in product recommendation, although we have adopted some recommendation algorithms, the accuracy is still not high enough, and many users are not interested in the recommended products. In customer service, the response speed and problem - solving ability of manual customer service are limited, which may lead to the loss of users. Also, in marketing activities, it is difficult to accurately target potential users, resulting in a low return on marketing investment.
