  4. Evaluating transformers as memory systems in reinforcement learning by Makkink, Thomas

    Published 2022
    “…Memory in reinforcement learning is particularly difficult as rewards are often sparse and distributed over many time steps. Early research into transformers as memory mechanisms for reinforcement learning indicated that the canonical model is not suitable, and that additional gated recurrent units and architectural modifications are necessary to stabilize these models. …”

  6. Analysis of long-term changes in populations of the Clanwiliam Cedar (Widdringtonia cedarbergensis) using repeat photography by White, Joseph Douglas Mandla

    Published 2015
    “…From the historical to repeat photosets there was an 8% increase in the proportion of mature adults and a 13% increase in the proportion of W. cedarbergensis individuals with sparse foliage cover. A generalized linear model was used to determine the effects of environmental factors on W. cedarbergensis mortality in natural populations.…”

  11. Sensor Data Fusion For Air Quality Monitoring by hesham, Mirna

    Published 2025
    “…Since traditional air quality monitoring methods often rely on geographically sparse and costly air quality monitoring stations, image-based air quality method- ologies are recently offering a compelling alternative that utilizes images from sources like satellites, traffic cameras, and even smartphones to monitor pollution levels by using estimation models, image-processing techniques, and deep-learning models. …”

    Published 2017
    “…The texture appearance of the ocean is described using Local Binary Pattern (LBP) descriptors. Two models are proposed: one model is a Gaussian Mixture (GMM) and the other, referred to as a Sparse Texture Model (STM), is a set of histogram texture distributions. …”

  14. Towards a theory of Deference in South Africa; Trans-Atlantic Lessons by Kenny, John

    Published 2014
    “…Rather the few post-1994 cases that have dealt expressly with deference will be adverted to, and an attempt made to elicit a skeletal model from the rather sparse dicta The paper will conclude with a modest proposal for a process rationale for deference, broadly based on a Skidmore-hard look paradigm to reconcile the two emerging streams of the jurisprudence. …”

  15. Localisation under Large Appearance Change by Church, Matthew

    Published 2024
    “…The inclusion of generated data reduces the requirement for frequent data collection, provided an adequate generation model can be trained. The experience, which is a collection of images and transforms describing a traversal of an environment is the primary means through which this generation of data can influence the network. …”
