Patent number: 12191007Abstract: Example embodiments relate to a method for training a predictive model from data. The method includes defining a multitude of predicates as binary functions operating on time sequences of the features or logical operations on the time sequences of the features. The method also includes iteratively training a boosting model by generating a number of new random predicates, scoring all the new random predicates by weighted information gain with respect to a class label associated with a prediction of the boosting model, selecting a number of the new random predicates with the highest weighted information gain and adding them to the boosting model, computing weights for all the predicates in the boosting model, removing one or more of the selected new predicates with the highest information gain from the boosting model in response to input from an operator. The method may include repeating the prior steps a plurality of times.Type: GrantFiled: September 29, 2017Date of Patent: January 7, 2025Assignee: Google LLCInventors: Kai Chen, Eyal Oren, Hector Yee, James Wilson, Alvin Rajkomar, Michaela Hardt

Publication number: 20210358579Abstract: A method is described for training a predictive model which increases the interpretability and trustworthiness of the model for end-users. The model is trained from data having multitude of features. Each feature is associated with a real value and a time component. Many predicates (atomic elements for training the model) are defined as binary functions operating on the features, and typically time sequences of the features or logical combinations thereof. The predicates can be limited to those functions which have human understandability or encode expert knowledge relative to a predication task of the model. We iteratively train a boosting model with input from an operator or human-in-the-loop. The human-in-the-loop is provided with tools to inspect the model as it is iteratively built and remove one or more of the predicates in the model, e.g. if it does not have indicia of trustworthiness, is not causally related to a prediction of the model, or is not understandable.Type: ApplicationFiled: September 29, 2017Publication date: November 18, 2021Inventors: Kai Chen, Eyal Oren, Hector Yee, James Wilson, Alvin Rajkomar, Michaela Hardt

Publication number: 20200388358Abstract: A machine learning method is described for generating labels for members of a training set where the labels are not directly available in the training set data. In a first stage of the method an iterative process is used to gradually build up a list of features (“partition features” herein) which are conceptually related to the class label using a human-in-the loop (expert). In a second part of the process we generate labels for the members of the training set, build up a boosting model using the labeling to come up with additional partition features, score the labeling of the training set members from the boosting model, and then with the human-in-the-loop evaluate a labels assigned to a small subset of the members depending on their score. The labels assigned to some or all of those members in the subset may be flipped depending on the evaluation. The final outcome of the process is an interpretable model that explains how the labels were generated and a labeled set of training data.Type: ApplicationFiled: September 29, 2017Publication date: December 10, 2020Inventors: Kai CHEN, Kun ZHANG, Jacob MARCUS, Eyal OREN, Hector YEE, Michaela HARDT, James WILSON, Alvin RAJKOMAR, Jian LU

Patent number: 10664855Abstract: This disclosure includes methods for predicting demand based on the price of a time-expiring inventory. An online system provides a connection between a manager of a time-expiring inventory and a plurality of clients. The online system provides a listing for the manager's time-expiring inventory to clients on the online system. The manager specifies the price of the time-expiring inventory in the listing. A demand function predicts the demand for the time-expiring inventory based on features of the listing and the time-expiring inventory. The online system determines a likelihood of receiving a request for the time-expiring inventory from a client on the online system based on the predicted demand. The online system may use the determined likelihoods to provide to the manager information about how changes in the price of the listing are likely to affect the demand for the time-expiring inventory.Type: GrantFiled: November 25, 2015Date of Patent: May 26, 2020Assignee: Airbnb, Inc.Inventors: Bar Ifrach, David Michael Holtz, Yangli Hector Yee, Li Zhang

Regression-tree compressed feature vector machine for time-expiring inventory utilization prediction
Patent number: 10621548Abstract: This disclosure includes systems for regression-tree-modified feature vector machine learning models for utilization prediction in time-expiring inventory. An online computing system receives a feature vector for a listing and inputs the feature vector and modified feature vectors into a demand function to generate demand estimates. The system inputs the demand estimates into a likelihood model to generate a set of request likelihoods, each request likelihood representing a likelihood that the time-expiring inventory will receive a transaction request at each of a set of test price and test times to expiration. The system further trains a regression tree model based on a set of training data comprising each of the request likelihoods from the set and the test price and test time period to expiration used to generate the demand estimate that was used to generate the request likelihood.Type: GrantFiled: November 19, 2019Date of Patent: April 14, 2020Assignee: Airbnb, Inc.Inventors: Spencer de Mars, Yangli Hector Yee, Peng Ye, Fenglin Liao, Li Zhang, Kim Pham, Julian Qian, Benjamin Yolken -
