Abstract: Techniques for code-free automated machine learning (ML) are described. Users can train high-quality ML models and pipelines without necessarily needing to write code by providing a training dataset to a code-free machine learning service. The service may deploy an ML orchestration function and a storage location on behalf of a user. When a modification is made to the storage bucket, such as by the user providing a training dataset, the orchestration function is invoked and can automatically initiate an AutoML process using at least the training data to train multiple ML model variants. The resultant ML model(s) and associated metrics can be provided to the user, deployed behind an endpoint, and/or used to generate inferences.

Abstract: Methods and systems described herein are directed to creating customized queries on data sets via selection of search elements based on meta-data from data set registrations. In some implementations, an automatic query system can register database elements with associated meta-data by receiving programming data objects, corresponding to database elements, with meta-data and adding the programming objects as selectable values for a user interface (UI). Each data object can define one or more elements for a table and/or column(s) within a table in a database. The automatic query system can provide the UI to a user to receive table and column selections. The automatic query system can select a root table to join the selected tables into, and generate a join query for the root table by inserting search string snippets, corresponding to selected tables and columns, into a query template.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for jointly training an encoder that generates a watermark and a decoder that decodes a data item encoded within the watermark. The training comprises obtaining a plurality of training images and data items. For each training image, a first watermark is generated using an encoder and a subsequent second watermark is generated by tiling two or more first watermarks. The training image is watermarked using the second watermark to generate a first error value and distortions are added to the watermarked image. A distortion detector predicts the distortions based on which the distorted image is modified. The modified image is decoded by the decoder to generate a predicted data item and a second error value. The training parameters of the encoder and decoder are adjusted based on the first and the second error value.

Abstract: An LED lamp and method are provided for autonomously changing the output brightness and color temperature of a plurality of LED strings to follow a first dimcurve in temporal synchronization with at least one other LED lamp. Synchronization is achieved based on a time of day determined using a clock signal. The output brightness and color temperature can transition from the first dimcurve to a second dimcurve over a predetermined number of scenes. The number of scenes is a function of a difference between the first dimcurve and the second dimcurve in at least one of the output brightness and the color temperature.

Abstract: A neural network is trained using transfer learning to analyze medical image data, including 2D, 3D, and 4D images and models. Where the target medical image data is associated with a species or problem class for which there is not sufficient labeled data available for training, the system may create enhanced training datasets by selecting labeled data from other species, and/or labeled data from different problem classes. During training and analysis, image data is chunked into portions that are small enough to obfuscate the species source, while being large enough to preserve meaningful context related to the problem class (e.g., the image portion is small enough that it cannot be determined whether it is from a human or canine, but abnormal liver tissues are still identifiable). A trained checkpoint may then be used to provide automated analysis and heat mapping of input images via a cloud platform or other application.
