Abstract: A method includes obtaining waveform return data including waveform return records for multiple sampling events associated with an observed area and determining a relevance score for the waveform return records of the waveform return data. The relevance score for a particular waveform return record is based, at least partially, on estimated information gain associated with the particular waveform return record. The method also includes, based on the relevance scores, selecting a first subset of waveform return records, where one or more waveform return records are excluded from the first subset of waveform return records. The method also includes generating image data based on the first subset of waveform return records.

Abstract: A method includes determining, using a physics-based model and based on a plurality of observations, first solution data. The first solution data is descriptive of a first estimated solution to an inverse problem associated with the plurality of observations, and the first solution data includes artifacts due, at least in part, to a count of observations of the plurality of observations. The method also includes performing a plurality of iterations of a gradient descent artifact reduction process to generate second solution data. The artifacts are reduced in the second solution data relative to the first solution data. A particular iteration of the gradient descent artifact reduction process includes determining, using a machine-learning model, a value of a gradient metric associated with particular solution data and adjusting the particular solution data based on the value of the gradient metric to generate updated solution data.

Abstract: A method includes obtaining historical data including sensor data from one or more sensors associated with a device and contextual data indicative of one or more conditions external to the device and independent of operation of the device. The method also includes providing at least a portion of the historical data as input to one or more machine-learning-based projection models to generate projection data associated with a future condition of the device. The method further includes providing input data to one or more machine-learning-based optimization models to determine one or more operational parameters that are expected to improve an operational metric associated with one or more devices. The one or more devices include the device, and the input data is based, at least in part, on the historical data and the projection data.

Abstract: A method includes using a machine-learning model to determine multiple sets of image data, each representing an estimated solution to an inverse problem associated with multiple waveform return measurements. First image data are based on a first set of waveform return measurements and first model parameters of the machine-learning model, and second image data are based on a second set of waveform return measurements and a second model parameters of the machine-learning model. The method also includes determining, based on the multiple sets of image data, a representative image. The method further includes generating output data that identifies a first area of the representative image as less reliable than a second area of the representative image based on a statistical evaluation of two or more sets of image data of the multiple sets of image data.

Abstract: A method includes determining a feature importance ranking for each pair of clusters of a plurality of clusters to generate a first plurality of feature importance rankings. The method further includes determining a feature importance ranking between a particular data element and each cluster to generate a second plurality of feature importance rankings. A distance value associated with each pair of clusters of the plurality of clusters is determined to generate a plurality of distance values, and a probability value associated with each data element is determined to generate a plurality of probability values. The method further includes weighting the first plurality of feature importance rankings based on the plurality of distance values to determine a first plurality of weighted feature importance rankings and weighting the second plurality of feature importance rankings based on the plurality of probability values to determine a second plurality of weighted feature importance rankings.
