The online store solved the problem of increasing demand for an expanded assortment. He asked us to improve the recommendation system for his users so that customers would be more inclined to buy new products for themselves, and not only from the niches of previous purchases. We collected data on customers and their purchases for 2 years, formed a metric that counts the increase in unique purchases in the user's basket over the test period and began to build a recommendation system. The most effective approach turned out to be an ensemble of a user-based approach to recommendations coupled with KNN on the product names in the receipt for each client. The forecast announced a 49% hit of recommendations in the client's future products, but this is only in theory, because recommendations affect the purchase itself. An A/B test was conducted, which showed a statistically significant result of the growth of total sales, among which the increase in purchases falling on new products for users was 30.5%

Objectives: to improve their forecasts of purchases by product categories in order to reduce the costs of illiquid, but at the same time fall into seasonal waves of increased demand.

As a result, sales increased, and warehouses began to overflow less often.

Task: the local TV channel wanted to reduce the burden on consultants and coordinators, to whom most of the clients turned.

We have collected all the detailed answers, made a Word to Vector model out of them and trained the annoying model from Spotify to select the most appropriate answer for the question. It was important to implement the functionality so that the client could call a person at any time or make a purchase directly from the chat, so we added a classifier that distinguished the client's requirements related to the purchase of an advertising placement from questions and from the requirements to call a person. As a result, the average response rate to the question became close to the usual offline request for help in the store, and consultants began to deal more with new, complex and atypical questions, and the company now saves all questions and answers for machine learning.
