Methods, systems, and apparatus, including computer programs encoded on computer storage media, for characterization of aggregate particles. A method includes obtaining, from a set of low fidelity sensors, first sensor data of a first portion of particles; obtaining, from a set of high fidelity sensors, second sensor data of the first portion of particles, the second sensor data comprising a higher fidelity representation of characteristics of the first portion of particles than the first sensor data; training a characterization model using the first sensor data and the second sensor data, the training comprising: providing, as training data to the characterization model, the second sensor data; and processing the second sensor data with the characterization model to correlate the first sensor data with the second sensor data. The first sensor data can indicate shape characteristics of each particle; and the second sensor data indicates a surface area of each particle.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for correcting timestamps in computer security telemetry data. A method includes: receiving, at a computer network security data analysis system, first log data identifying a plurality of first events occurring on a computer network, the first log data including, for each first event, a respective first timestamp identifying when the first event occurred, the first timestamp including a first hour value, a first minute value, and a first second value; and generating first modified log data, the first modified log data including, for each first event, a first modified timestamp including the first minute value and the first second value from the log data and a first modified hour value that represents an hour value from a current time at which the first log data was received at the computer network security data analysis system.
