Automatically Debugging AutoML Pipelines using Maro: ML Automated Remediation Oracle (Extended Version)
No full textMachine learning in practice often involves complex pipelines for data
cleansing, feature engineering, preprocessing, and prediction. These pipelines
are composed of operators, which have to be correctly connected and whose
hyperparameters must be correctly configured. Unfortunately, it is quite common
for certain combinations of datasets, operators, or hyperparameters to cause
failures. Diagnosing and fixing those failures is tedious and error-prone and
can seriously derail a data scientist's workflow. This paper describes an
approach for automatically debugging an ML pipeline, explaining the failures,
and producing a remediation. We implemented our approach, which builds on a
combination of AutoML and SMT, in a tool called Maro. Maro works seamlessly
with the familiar data science ecosystem including Python, Jupyter notebooks,
scikit-learn, and AutoML tools such as Hyperopt. We empirically evaluate our
tool and find that for most cases, a single remediation automatically fixes
errors, produces no additional faults, and does not significantly impact
optimal accuracy nor time to convergence.Comment: Extended version of MAPS 2022 pape
Business Organization and Coordination in Marketing Specialty Hogs: A Comparative Analysis of Two Firms from Iowa
No full textWe study business organization and coordination of specialty-market hog production using a comparative analysis of two Iowa pork niche-marketing firms.� We describe and analyze each firm's management of five key organizational challenges: planning and logistics, quality assurance, process verification and management of "credence attributes," business structure, and profit sharing.� Although each firm is engaged in essentially the same activity, there are substantial differences across the two firms in the way production and marketing are coordinated.� These differences are partly explained by the relative size and age of each firm, thus highlighting the importance of organizational evolution in agricultural markets, but are also partly the result of a formal organizational separation between marketing and production activities in one of the firms.specialty hogs
Komuna Maro: Artistic Research as Collective Knowledge Production in a Capitalocene Seascape
No full textThe notion of the ocean as a pristine expanse, untouched by human culture and technology, no longer reflects present reality. In what historian and geographer Jason W. Moore terms the Capitalocene, both human and non‐human inhabitants of marine and coastal regions are deeply embedded in multi‐scalar metabolic processes intrinsic to the capitalist mode of socio‐ecological (re)production. Despite the urgency of transforming these planetary circuits, comprehensive and transcultural forms of oceanic knowledge remain scarce, hindered by language barriers and disciplinary divides. Weaving through the story of Komuna Maro, an arts‐based research project focused on networks of marine communities, technologies, and infrastructures in the northern Adriatic, the article explores possibilities for overcoming these gaps by engaging with the following questions: How can we conceive of the ocean as a material lifeworld without overlooking the political and economic realities that interact with and leave traces in the depths of oceanic matter? What epistemological framework might establish a logical connection between the brutal exploitation of workers in maritime economies and the devastation of non‐human marine life, without resorting to a generalized critique of “Western modernity,” which offers limited analytical tools for understanding the maritime dimension of global capitalism? How can we generate and share genuinely popular, critical, transdisciplinary, and transcultural forms of knowledge that call for a (re)invention of an “emancipatory oceanic internationalism,” rather than a retreat into localized and fragmented vernacular knowledge systems? Finally, what is—or could be—the role of artistic research in addressing these questions

Maro : a model of emotions using ontology
No full textEste trabalho apresenta um framework que permite a programação de agentes capazes de perceberem seus próprios estados emocionais. O framework foi desenvolvido em Java com base na plataforma multi-agente Jason, estendendo a base de crenças de agentes Jason a fim de utilizar a ontologia afetiva desenvolvida. Além disso, o ambiente foi construído a partir de uma base de conhecimento que descreve rotinas em ambientes simulados. Um mecanismo de avaliação das emoções baseando-se nas anotações dos objetos foi construído apoiado por uma ontologia de preferência sobre essas anotações. Dessa forma, aplicações de entretenimento poderiam utilizar o sistema ou as bases de conhecimento apresentadas para diferentes propósitos. A criação de um mapa onde os personagens atuam, e a criação da rotina de cada personagem e suas preferências são alguns exemplos de utilizações. Para validação do framework desenvolvido, dois exemplos foram construídos. O primeiro utilizou a maior parte dos grupos afetivos da ontologia proposta, com a finalidade principal de demonstrar o modelo implementado. Já o segundo usa apenas um grupo emotivo e serve para demonstrar a utilização conjunta de todas as ontologias apresentadas.This work presents a framework built on top of the Jason platform (BORDINI et al., 2004) to allow the development of software agents that have emotional states. The framework was developed in Java and extends the belief base of Jason agents so as to use an ontology for the OCC affective model (ORTONY; COLLINS; CLORE, 1988) that has been created as part of this work. The developed belief base allows an agent to perceive its own emotions throw inferring new beliefs based on the agent’s appraisal of the state of the environment. In addition, a model of agents’ routine tasks was defined, as was a model for agents’ preferences about aspects of environment, helping automate the ascription of emotional states. Finally, in order to validate the developed framework, two applications were developed. The first demonstrates the use of various different emotions from the affective model and the second uses in a single application all the ontologies and models developed as part of this work
Can smartphones and tablets improve the management of childhood illness in Tanzania? A qualitative study from a primary health care worker’s perspective
No full textThe impact of the Integrated Management of Childhood Illness (IMCI) strategy has been less than anticipated because of poor uptake. Electronic algorithms have the potential to improve quality of health care in children. However, feasibility studies about the use of electronic protocols on mobile devices over time are limited. This study investigated constraining as well as facilitating factors that influence the uptake of a new electronic Algorithm for Management of Childhood Illness (ALMANACH) among primary health workers in Dar es Salaam, Tanzania.; A qualitative approach was applied using in-depth interviews and focus group discussions with altogether 40 primary health care workers from 6 public primary health facilities in the three municipalities of Dar es Salaam, Tanzania. Health worker's perceptions related to factors facilitating or constraining the uptake of the electronic ALMANACH were identified.; In general, the ALMANACH was assessed positively. The majority of the respondents felt comfortable to use the devices and stated that patient's trust was not affected. Most health workers said that the ALMANACH simplified their work, reduced antibiotic prescription and gave correct classification and treatment for common causes of childhood illnesses. Few HWs reported technical challenges using the devices and complained about having had difficulties in typing. Majority of the respondents stated that the devices increased the consultation duration compared to routine practice. In addition, health system barriers such as lack of staff, lack of medicine and lack of financial motivation were identified as key reasons for the low uptake of the devices.; The ALMANACH built on electronic devices was perceived to be a powerful and useful tool. However, health system challenges influenced the uptake of the devices in the selected health facilities

Bioengineered Skin in Psoriasis Modeling: Investigation of Automated Injection Molding of Dermo-Epidermal Models as compared with Benchmark Manual Fabrication.
No full textBioengineered skin was initially developed for clinical application in reconstructive surgery, but nowadays it is also considered as a suitable skin model for research. Research applications range from assessment of cosmetic and pharmaceutical products to the modeling of pathological skin conditions. For example, psoriasis is a complicated skin disease that strongly concerns the scientific community because of its unclear pathogenesis and the current inability to cure it. The Pharmacogenomics Lab of ETH has been working on the development of psoriatic skin models in order to investigate the driving mechanisms of the disease and to later implement high-throughput drug screening to explore treatment possibilities. However, the manual production into transwell inserts results in unstable, self-contracting and inconsistent skin models, pain points that the Pharmacogenomics Lab would like to eliminate. A recent collaboration between the Product Development Group and the Pharmacogenomics Lab has been recently initiated in an attempt to standardize the fabrication of the psoriatic skin models. For this purpose, this Master Thesis focused on the investigation of the potentials and limitations of automated injection molding, a method developed by the Product Development Group, in the generation of consistent and representative dermo-epidermal models for psoriatic skin. After a series of experiments, it was seen that in-mold fabrication achieves homogeneous and consistent dermal hydrogels that maintain their dimensions throughout the whole cultivation period regardless of the collagen concentration employed for the dermal matrix, while automated injection molding allows the utilization of collagen concentrations higher than the unstable 5mg/ml, traditionally used in the manual fabrication method. All collagen concentrations exhibited similar biological performance, but the optimum fibroblasts viability was achieved in case of 5mg/mL, meaning that the whole injection molding process should be faster and even simpler to fully prevail over manual fabrication of skin models and better fit the requirements of skin disease research. Keratinocytes viability and differentiation was similar for all mold designs, all collagen concentrations and both fabrication methods. Development of a first psoriatic model, consisting of psoriatic fibroblasts and healthy keratinocytes, did not show any direct effect of diseased fibroblasts on keratinocytes proliferation and differentiation as the epidermal layer of the psoriatic model was very similar to this one of the healthy model.Evaluation of the automated seeding of keratinocytes for further standardization of the process and elongation of the psoriatic model’s cultivation period for a more thorough study should be the next steps. In the long-term, incorporation of all the psoriasis-related cells and molecules in a simple and fast way, as well as further advancements in the mold design to facilitate a direct high-throughput drug screening should be considered.Biomedical Engineering | Biomaterials and Tissue Biomechanic
