Publication number: 20230252281Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, that obtain a first machine learning model that is configured to output a score. The training examples can each include feature values that represent features of an item, and an outcome label for the item. From the training examples, training pairs of training examples are determined. For each training pair: (i) a score is generated for each training example in the training pair using the first machine learning model; and (ii) for the training pair, a score difference of the scores generated for the training examples in the training pair is determined. Using the training pairs and the score differences, a second machine learning model is trained to produce score differences that, for the same training examples, are within a threshold value of the score differences produced by the first machine learning model.Type: ApplicationFiled: June 2, 2022Publication date: August 10, 2023Inventors: Gil Shamir, Zhuoshu Li

Patent number: 11475309Abstract: Thus, aspects of the present disclosure address model “blow up” by changing the functionality of the activation, thereby providing “dead” or “dying” neurons with the ability to recover from this situation. As one example, for activation functions that have an input region in which the neuron is turned off by a 0 or close to 0 gradient, a training computing system can keep the neuron turned off when the gradient pushes the unit farther into the region (e.g., by applying an update with zero or reduced magnitude). However, if the gradient for the current training example (or batch) attempts to push the unit towards a region in which the neuron is active again, the system can allow for a non-zero gradient (e.g., by applying an update with standard or increased magnitude).Type: GrantFiled: April 14, 2020Date of Patent: October 18, 2022Assignee: GOOGLE LLCInventor: Gil Shamir

Publication number: 20220108219Abstract: Systems and methods leverage low complexity (e.g., linear overall, fixed per example) analytical approximations to perform machine learning problems such as, for example, the sparse online logistic regression problem. Unlike variational inference and other methods, the proposed systems and methods lead to analytical closed forms, lowering the practical number of computations. Further, unlike techniques used for dense features sets, such as Gaussian Mixtures, the proposed systems and methods allow for sparse problems with huge feature sets without increasing complexity. With the analytical closed forms, there is also no need for applying stochastic gradient methods on surrogate losses, and for tuning and balancing learning and regularization parameters of such methods.Type: ApplicationFiled: October 1, 2021Publication date: April 7, 2022Inventors: Gil Shamir, Wojciech Szpankowski

Publication number: 20210158156Abstract: Systems and methods can improve the reproducibility of neural networks by distilling from ensembles. In particular, aspects of the present disclosure are directed to a training scheme that utilizes a combination of an ensemble of neural networks and a single, “wide” neural network that is more powerful (e.g., exhibits a greater accuracy) than the ensemble. Specifically, the output of the ensemble can be distilled into the single neural network during training of the single neural network. After training, the single neural network can be deployed to generate inferences. In such fashion, the single neural model can provide a superior prediction accuracy while, during training, the ensemble can serve to influence the single neural network to be more reproducible. In addition, an additional single wide tower can be added to generate another output, that can be distilled to the single neural network, to further improve its accuracy.Type: ApplicationFiled: September 18, 2020Publication date: May 27, 2021Inventors: Gil Shamir, Lorenzo Coviello

Publication number: 20210133565Abstract: Aspects of the present disclosure are directed to novel activation functions which enable improved reproducibility and accuracy tradeoffs in neural networks. In particular, the present disclosure provides a family of activation functions that, on one hand, are smooth with continuous gradient and optionally monotonic but, on the other hand, also mimic the mathematical behavior of a Rectified Linear Unit (ReLU). As examples, the activation functions described herein include a smooth rectified linear unit function and also a leaky version of such function. In various implementations, the proposed functions can provide both a complete stop region and a constant positive gradient (e.g., that can be 1) pass region like a ReLU, thereby matching accuracy performance of a ReLU. Additional implementations include a leaky version and/or functions that feature different constant gradients in the pass region.Type: ApplicationFiled: June 16, 2020Publication date: May 6, 2021Inventors: Gil Shamir, Dong Lin, Sergey Ioffe
