Generalizable semi-supervised learning method to estimate mass from sparsely annotated images

no code implementations5 Mar 2020 Muhammad K. A. Hamdan, Diane T. Rover, Matthew J. Darr, John Just

The deep neural network is initially trained to predict mass on laboratory data (bamboo) and then transfer learning is utilized to apply the same methods to estimate mass of sugarcane.

Granular Learning with Deep Generative Models using Highly Contaminated Data

no code implementations6 Jan 2020 John Just

An approach to utilize recent advances in deep generative models for anomaly detection in a granular (continuous) sense on a real-world image dataset with quality issues is detailed using recent normalizing flow models, with implications in many other applications/domains/data types.

Deep Generative Models Strike Back! Improving Understanding and Evaluation in Light of Unmet Expectations for OoD Data

no code implementations12 Nov 2019 John Just, Sambuddha Ghosal

Finally, a look to the previous generation of generative models in the form of probabilistic principal component analysis is inspired, and revisited for the same data-sets and shown to work really well for discriminating anomalies based on likelihood in a fully unsupervised fashion compared with pixelCNN++, GLOW, and real NVP with less complexity and faster training.

Mass Estimation from Images using Deep Neural Network and Sparse Ground Truth

no code implementations5 Aug 2019 Muhammad K. A. Hamdan, Daine T. Rover, Matthew J. Darr, John Just

Since the number of images for any given run are too large to fit on typical GPU vRAM, an implementation is shown that compensates for the limited memory but still achieve fast training times.
