Denoising diffusion probabilistic models (DDPMs) (Ho et al. 2020) have shown impressive results on image and waveform generation in continuous state spaces. Here, we introduce Discrete Diffusion Probabilistic Models (D3PMs), diffusion-like generative for discrete data that generalize the multinomial model of Hoogeboom 2021, by going beyond corruption processes with uniform transition probabilities. This includes matrices mimic Gaussian kernels space, based nearest neighbors embedding...
Language models exhibit complex, diverse behaviors when prompted with free-form text, making it difficult to characterize the space of possible outputs. We study problem behavior elicitation, where goal is search for prompts that induce specific target (e.g., hallucinations or harmful responses) from a language model. To navigate exponentially large prompts, we train investigator map randomly-chosen distribution outputs elicit them, similar amortized Bayesian inference. do this through...
We present a novel programming language design that attempts to combine the clarity and safety of high-level functional languages with efficiency parallelism low-level numerical languages. treat arrays as eagerly-memoized functions on typed index sets, allowing abstract function manipulations, such currying, work arrays. In contrast composing primitive bulk-array operations, we argue for an explicit nested indexing style mirrors application arguments. also introduce fine-grained effects...
This paper presents a novel approach for fitting length data to the Schnute growth model. Cohorts were fitted manually time series of distributions from two stocks (Clarence and Hunter Rivers) Metapenaeus macleayi considered analogous individuals tag–recapture data, in order estimate parameters. Data Clarence males best three-parameter Model (L∞ = 21.3 mm CL, κ 0.025 day–1 γ –1.35), whereas those two-parameter version model 33.5 0.009 0 fixed). The equivalent von Bertalanffy function was fit...
Effective fisheries management of mobile species relies on robust knowledge animal behaviour and habitat-use. Indices can be useful for interpreting catch-per-unit-effort data which acts as a proxy relative abundance. Information about habitat-use inform stocking release strategies or the design marine protected areas. The Giant Mud Crab (Scylla serrata; Family: Portunidae) is swimming estuarine crab that supports significant harvest throughout Indo-West Pacific, but little known fine-scale...
Portunus pelagicus (blue swimmer crab) is widely distributed and fished throughout the indo-west Pacific, but little known of its biology ecology in southeast Australia. In this study, reproductive P. inhabiting Wallis Lake, a large coastal lake that supports largest regional commercial fishery for species was investigated. Males females with mature gonads occur fishing season (November to July), however, ovigerous are most prevalent November December. The mean size at which 50% reached...
Abstract Portunid crabs are an iconic, high value species in NSW, but catches highly variable space and time. Substantial variation biomass is observed both exploited unfished populations, environmental effects on distribution abundance important factor contributing to this variability. Predicting responding variability a challenge for management sustainability of populations. We examine spatial temporal Blue Swimmer Crab ( Portunus armatus ) over 2.5 year trapping survey two temperate...
Abstract In response to experimental evidence and anecdotal concern about bycatch in the net‐covered traps used increasingly by recreational commercial fishers target giant mud crabs Scylla serrata New South Wales, Australia, experiments were done examine utility of escape gaps reducing Yellowfin Bream Acanthopagrus australis (also known as Surf Bream) undersized crabs. each two rivers, 10 different treatments comprising four sizes rectangular, horizontal (85 × 45 mm, 85 55 95 mm) a control...
Abstract Spawning is a key life history event for aquatic species that can be triggered by environmental signals. For estuarine-dependent species, the timing of such triggers important determining future patterns in recruitment. Here, we used acoustic telemetry to identify potential drivers spawning migration female Giant Mud Crabs ( Scylla serrata ). Eighty-nine mature crabs were tagged two subtropical south-east Australian estuaries, Clarence River (~ 29.4°S) and Kalang 30.5°S), during...
Abstract Larval dispersal and connectivity have important implications for fisheries management, especially species with life cycles influenced by ocean boundary currents. Giant Mud Crab ( Scylla serrata ) Blue Swimmer Portunus armatus are two estuarine portunid crabs (Family: Portunidae) that support significant commercial recreational harvest in eastern Australia. migrate to coastal waters spawn, while spawn primarily within estuaries they occasionally followed larval the East Australian...
Two replicate multi-mesh gill and trammel nets, each comprising five 30 m long panels made from different-sized mesh (38, 54, 70, 90 100 mm stretched openings) were fished in a south-east Australian barrier estuary over seven nights to evaluate their potential as sampling gears for fishery-independent surveys of estuarine fish assemblages. There no differences composition structure assemblages, mean abundance, or diversity catches between the two types net. The differed sizes, with 38 54...
