Abstract: An aspect of the invention relates to the field of an automatic chat support and analytics (recommender) engine for digital sales. The analytics engine interactively and iteratively collects the feature value of a client's profile by automatically generating questions in different styles and extracting the semantic information from the client's responses. The accumulated feature information for the client can enhance the capability of a recommender engine. Specifically, for item recommendation, the recommender engine includes components for item scoring and its confidence estimation, feature importance scoring, missing feature inference and confidence estimation by smoothing the corresponding feature values from the most similar clients. The recommender engine also involves a client response analytics component, which performs a quality check by evaluating the consistency between the inferred feature value from the similar clients and the extracted one from the client's response.

Abstract: A computer receives a first audio signal that is acquired by a first user device used by a first user in a conference and a second audio signal that is acquired by a second user device used by a second user in the conference. The computer processes the first audio signal based on the second audio signal to improve quality of the first audio signal, and sends the processed first audio signal to the conference.

Abstract: Embodiments include predicting transactions by an entity and identifying promotions to offer the entity. Aspects include parsing a plurality of event records corresponding to a plurality of entities respectively. Aspects also include identifying a sequence of events corresponding to the entity and discretizing time durations and event values of the sequence of events into discrete symbolic values. Aspects further include generating a temporal pattern of events in the sequence of events, the temporal pattern including a sequence of transaction-symbols representative of the time duration and the event value of the events in the sequence of events of the entity and predicting a next transaction based on the temporal pattern.

Abstract: An aspect of post-lending credit management includes collecting data associated with events for a plurality of clients, serializing the data by time stamp and value to produce a client-based time series of the events, and performing feature generalization for the time series. Feature generation includes grouping the client-based time series according to a selected feature to produce feature-based time series, defining a feature-based default burst and a threshold value for the feature-based time series, identifying a point in time on the feature-based time series when the feature-based default burst reaches the threshold value, determining a cause and effect relationship between default events occurring across the plurality of feature-based time series from the feature-based default burst, and outputting feature-based default rules from the corresponding cause and effect relationship. An aspect also includes predicting an occurrence of a default event and time for a particular client from results of the feature generalization.

Abstract: A blockchain of transactions may be referenced for various purposes and may be later accessed by interested parties for ledger verification. One example method of operation may comprise one or more of identifying a production date associated with a product, creating a unique code to represent the production date and the product based on a hash of one or more blocks of a blockchain, and forwarding the unique code to a verification server to verify the product.
