We propose a novel self-supervised method for fine-tuning deep face representations called Face-Grouping on Graphs. We apply our method to automatic face grouping, where characters are to be separated based on their identity. To solve this problem, a graph structure with positive and negative edges over a set of face-tracks based on their temporal overlap and similarity constraints is induced, which requires no manual labor. We compute feature representations over sub-sequences of each track (sub-tracks) in order to obtain robust features whilst being able to utilize information contained in face variance. Each sub-track is given the ability to exchange information with adjacent sub-tracks via a typed graph neural network running over the induced graph. This allows us to push each representation in a direction in feature space that groups all representations of the same character together and separates representations of different characters. We show that our method is capable of improving clustering accuracy on popular video face clustering datasets The Big Bang Theory and Buffy the Vampire Slayer by 4.9% and 17.0% respectively compared to baseline performance, and 0.52% respective 5.55% compared to state-of-the-art methods. Additionally, we achieve 19.0% absolute increase in B-3 F-Score on Harry Potter 1 (ACCIO) over other state-of-the-art unsupervised methods. We provide performance metrics on all episodes of The Big Bang Theory and Buffy the Vampire Slayer to enable further comparison in the future.

Citrus postbloom fruit drop is caused by a slow-growing orange strain of Colletotrichum gloeosporioides (SGO). A semiselective medium was developed to isolate the pathogen and differentiate it from the ubiquitous fast-growing gray saprophytic strain of C. gloeosporioides (FGG). Addition of streptomycin to potato-dextrose agar (PDA) at 300 mg/L suppressed contaminants without affecting growth of either strain Of C. gloeosporioides. When plates were incubated for 4 days at the optimum temperature of 27 C for growth of the two strains, FGG colonies often overgrew SGO colonies. Incubation of plates for 4 days at 18 C restricted colony size of both isolates. When incubated for one more day at 27 C, SGO colonies produced abundant orange conidia, whereas FGG colonies developed characteristic dark pigmentation of hyphae. Addition of copper hydroxide (42 mg/L Cu) to PDA + streptomycin reduced contamination only slightly but enhanced orange color development of SGO colonies, facilitating counting of colonies. Plating of citrus tissue washings on PDA + streptomycin + copper hydroxide and incubation for 4 days at 18 C plus 1 day at 27 C optimized recovery of the SGO isolates.
