Publication number: 20240112808Abstract: A computer-implemented method includes receiving, by a computing device, a particular textual description of a scene. The method also includes applying a neural network for text-to-image generation to generate an output image rendition of the scene, the neural network having been trained to cause two image renditions associated with a same textual description to attract each other and two image renditions associated with different textual descriptions to repel each other based on mutual information between a plurality of corresponding pairs, wherein the plurality of corresponding pairs comprise an image-to-image pair and a text-to-image pair. The method further includes predicting the output image rendition of the scene.Type: ApplicationFiled: December 14, 2023Publication date: April 4, 2024Inventors: Melissa Strader, William Ito, Christopher Co, Katherine Chou, Alvin Rajkomar, Rebecca Rolfe

Patent number: 11935634Abstract: A system for predicting and summarizing medical events from electronic health records includes a computer memory storing aggregated electronic health records from a multitude of patients of diverse age, health conditions, and demographics including medications, laboratory values, diagnoses, vital signs, and medical notes. The aggregated electronic health records are converted into a single standardized data structure format and ordered arrangement per patient, e.g., into a chronological order. A computer (or computer system) executes one or more deep learning models trained on the aggregated health records to predict one or more future clinical events and summarize pertinent past medical events related to the predicted events on an input electronic health record of a patient having the standardized data structure format and ordered into a chronological order.Type: GrantFiled: August 30, 2017Date of Patent: March 19, 2024Assignee: Google LLCInventors: Alexander Mossin, Alvin Rajkomar, Eyal Oren, James Wilson, James Wexler, Patrik Sundberg, Andrew Dai, Yingwei Cui, Gregory Corrado, Hector Yee, Jacob Marcus, Jeffrey Dean, Benjamin Irvine, Kai Chen, Kun Zhang, Michaela Hardt, Xiaomi Sun, Nissan Hajaj, Peter Junteng Liu, Quoc Le, Xiaobing Liu, Yi Zhang

Publication number: 20210361227Abstract: The present disclosure provides systems and methods that generating health diagnostic information from an audio recording. A computing system can include a machine-learned health model comprising that includes a sound model trained to receive data descriptive of a patient audio recording and output sound description data. The computing system can include a diagnostic model trained to receive the sound description data and output a diagnostic score. The computing system can include at least one tangible, non-transitory computer-readable medium that stores instructions that, when executed, cause the processor to perform operations. The operations can include obtaining the patient audio recording; inputting data descriptive of the patient audio recording into the sound model; receiving, as an output of the sound model, the sound description data; inputting the sound description data into the diagnostic model; and receiving, as an output of the diagnostic model, the diagnostic score.Type: ApplicationFiled: May 4, 2018Publication date: November 25, 2021Inventors: Katherine Chou, Michael Dwight Howell, Kasumi Widner, Ryan Rifkin, Henry George Wei, Daniel Ellis, Alvin Rajkomar, Aren Jansen, David Michael Parish, Michael Philip Brenner

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
