Summary
Machine learning (ML) experts view algorithm opacity not as a flaw, but as a virtue, embracing unexpected outcomes. This perspective emerged from ML
Area of Science:
- Sociology of algorithms
- Science and Technology Studies (STS)
- Artificial Intelligence (AI) ethics
Background:
- Opacity of machine learning (ML) algorithms is a significant concern.
- Sociology of algorithms posits opacity is socially constructed, not inherent.
- Previous focus on mechanical objectivity contrasted human inconsistency with machine reliability.
Purpose of the Study:
- To investigate the epistemic culture of ML experts regarding algorithm opacity.
- To demonstrate how ML experts valorize opacity as an epistemic virtue.
- To trace the social and historical origins of this valorization.
Main Methods:
- Sixty in-depth, semi-structured interviews with ML experts and data scientists.
- Historical research on the origins of data science and ML.
- Qualitative analysis of expert interviews and historical documents.
Main Results:
- ML experts embrace algorithm opacity, viewing unexpected outcomes as a sign of advanced predictive capacity.
- Opacity is transformed from a problem into an epistemic virtue within ML.
- This valorization is linked to jurisdictional struggles differentiating ML from AI expert systems and inferential statistics.
Conclusions:
- The epistemic culture of ML experts actively constructs opacity as a virtue.
- This construction aids in establishing ML expertise and differentiating it from related fields.
- Understanding this social construction is crucial for addressing concerns about ML transparency and accountability.

Strategies for Assessing and Addressing Confounding
364
Confounding is a critical issue in epidemiological studies, often leading to misleading conclusions about associations between exposures and outcomes. It occurs when the relationship between the exposure and the outcome is mixed with the effects of other factors that influence the outcome. Given that, addressing confounding is of high importance for drawing accurate inferences in research.
Confounding can be addressed at both the design phase of a study and through analytical methods after data...

Bias
7.2K
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

Trial and Error and Algorithm
392
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Blinding
3.8K
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Mechanistic Models: Compartment Models in Algorithms for Numerical Problem Solving
292
Mechanistic models play a crucial role in algorithms for numerical problem-solving, particularly in nonlinear mixed effects modeling (NMEM). These models aim to minimize specific objective functions by evaluating various parameter estimates, leading to the development of systematic algorithms. In some cases, linearization techniques approximate the model using linear equations.
