<h2>3. Managing error: from the sublime to the risky algorithm</h2>
|
|
|
|
|
|
<div data-custom-style="Body Text">
|
|
|
|
|
|
<p>Our third emerging figuration concerns the place of the error. A
|
|
|
|
|
|
large body of literature examines actual and speculative cases of
|
|
|
|
|
|
algorithmic prediction based on self-learning systems (Azar et al.,
|
|
|
|
|
|
2021). Central to these analyses is the boundary-drawing performed by
|
|
|
|
|
|
such algorithmic devices, enacting (in)security by rendering their
|
|
|
|
|
|
subjects as more- or less-risky others (Amicelle et al., 2015: 300;
|
|
|
|
|
|
Amoore and De Goede, 2005; Aradau et al., 2008; Aradau and Blanke, 2018)
|
|
|
|
|
|
based on a spectrum of individual and environmental features (Calhoun,
|
|
|
|
|
|
2023). In other words, these predictive devices conceptualize risk as
|
|
|
|
|
|
something produced by, and thus external to, security technologies.</p>

</div>
|
|

|

<div data-custom-style="Body Text">
|
|
|
|
|
|
<p>In this critical literature on algorithmic practices, practitioners
|
|
|
|
|
|
working with algorithmic technologies are often critiqued for
|
|
|
|
|
|
understanding software as “sublime” (e.g. Wilcox, 2017: 3). However, in
|
|
|
|
|
|
our diagrams, algorithmic vision appears as a practice of managing
|
|
|
|
|
|
error. The practitioners we interviewed are aware of the error-prone
|
|
|
|
|
|
nature of their systems but know it will never be perfect, and see it as
|
|
|
|
|
|
a key metric that needs to be acted upon.</p>
|
|
|
|
|
|
</div>
|
|
|
|
|
|
<div data-custom-style="Body Text">
|
|
|
|
|
|
<p>The most prominent way in which error figures in the diagrams is in
|
|
|
|
|
|
its quantified form of the true positive and false positive rates, TPR
|
|
|
|
|
|
and FPR. The significance and definition of these metrics is stressed by
|
|
|
|
|
|
CTO Gerwin van der Lugt (Diagram 6). In camera surveillance, the false
|
|
|
|
|
|
positive rate could be described as the number of fales positive
|
|
|
|
|
|
classifications relative to the number of video frames being analyzed.
|
|
|
|
|
|
Upon writing down these definitions, van der Lugt corrected his initial
|
|
|
|
|
|
definitions, as these definitions determine the work of his development
|
|
|
|
|
|
team, the ways in which his clients — security operators — engage with
|
|
|
|
|
|
the technology, and whether they perceive the output of the system as
|
|
|
|
|
|
trustworthy.</p>

of their precise definition.</p>

|

|
<p>The figuration of algorithmic security vision as inherently imprecise
|
|
|
|
|
|
affects the operationalization of security practices. Van der Lugt’s
|
|
|
|
|
|
example concerns whether the violence detection algorithm developed by
|
|
|
|
|
|
Oddity.ai should be trained to categorize friendly fighting
|
|
|
|
|
|
(<em>stoeien</em>) between friends as “violence” or not. In this
|
|
|
|
|
|
context, van der Lugt finds it important to differentiate what counts as
|
|
|
|
|
|
false positive in the algorithm’s evaluation metric from an error in the
|
|
|
|
|
|
algorithm’s operationalization of a security question.</p>
|
|
|
|
|
|
</div>
|
|
|
|
|
|
<div data-custom-style="Body Text">
|
|
|
|
|
|
<p>He gives two reasons to do so. First, he anticipates that the
|
|
|
|
|
|
exclusion of <em>stoeien</em> from the category of violence would
|
|
|
|
|
|
negatively impact TPR. In the iterative development of self-learning
|
|
|
|
|
|
systems, the TPR and FPR, together with the true and false
|
|
|
|
|
|
<em>negative</em> rates must perform a balancing act. Van der Lugt
|
|
|
|
|
|
outlines that with their technology they aim for fewer than 100 false
|
|
|
|
|
|
positives per 100 million frames per week. The FPR becomes indicative of
|
|
|
|
|
|
the algorithm’s quality, as too many faulty predictions will desensitize
|
|
|
|
|
|
the human operator to system alerts.
|
|
|
|
|
|
</p>
|
|
|
|
|
|
</div>
|
|
|
|
|
|
<div data-custom-style="Body Text">
|
|
|
|
|
|
<p>This leads to van der Lugt’s second point: He fears that the
|
|
|
|
|
|
exclusion of <em>stoeien</em> from the violence category might cause
|
|
|
|
|
|
unexpected biases in the system. For example, instead of distinguishing
|
|
|
|
|
|
violence from <em>stoeien</em> based on people’s body movements, the
|
|
|
|
|
|
algorithm might make the distinction based on their age. For van der
|
|
|
|
|
|
Lugt, this would be an undesirable and hard to notice form of
|
|
|
|
|
|
discrimination. In developing algorithmic (in)security, error is figured
|
|
|
|
|
|
not merely as a mathematical concept but (as shown in Diagram 6) as a
|
|
|
|
|
|
notion that invites pre-emption — a mitigation of probable failure — for
|
|
|
|
|
|
which the developer is responsible. The algorithmic condition of
|
|
|
|
|
|
security vision is figured as the pre-emption of error.</p>

<p>Diagram 7. By drawing errors on a timeline, van Rest calls attention

to the pre-emptive nature of error in the development process of

computer vision technologies.</p>

<p>According to critical AI scholar Matteo Pasquinelli, “machine
|
|
|
|
|
|
learning is technically based on formulas for error correction” (2019:
|
|
|
|
|
|
2). Therefore, any critical engagement with such algorithmic processes
|
|
|
|
|
|
needs to go beyond citing errors, “for it is precisely through these
|
|
|
|
|
|
variations that the algorithm learns what to do” (Amoore, 2019: 164),
|
|
|
|
|
|
pushing us to reconsider any argument based on the inaccuracy of the
|
|
|
|
|
|
systems.</p>

|
|
<p>The example of <em>stoeien</em> suggests that it is not so much a
|
|
|
|
|
|
question if, or how much, these algorithms err, but how these errors are
|
|
|
|
|
|
anticipated and negotiated. Thus, taking error as a hallmark of machine
|
|
|
|
|
|
learning we can see how practices of (in)security become shaped by the
|
|
|
|
|
|
notion of mathematical error well beyond their development stages. Error
|
|
|
|
|
|
figures centrally in the development, acquisition and deployment of such
|
|
|
|
|
|
devices. As one respondent indicated, predictive devices are inherently
|
|
|
|
|
|
erroneous, but the quantification of their error makes them amenable to
|
|
|
|
|
|
"risk management.”</p>

|
|
|
|
|
</div>
|
|
|
|
|
|
<div data-custom-style="Body Text">
|
|
|
|
|
|
<p>While much has been written about security technologies as a device
|
|
|
|
|
|
<em>for</em> risk management, little is known about how security
|
|
|
|
|
|
technologies are conceptualized as objects <em>of</em> risk management.
|
|
|
|
|
|
What happens then in this double relation of risk? The figure of the
|
|
|
|
|
|
error enters the diagrams as a mathematical concept, throughout the
|
|
|
|
|
|
conversations we see its figure permeate the discourse around
|
|
|
|
|
|
algorithmic security vision. By figuring algorithmic security vision
|
|
|
|
|
|
through the notion of error, risk is placed at the heart of the security
|
|
|
|
|
|
apparatus.

<h1>Con-figurations of algorithmic security vision: fragmenting

accountability and expertise</h1>

<div data-custom-style="Body Text">
|

|
<p>In the previous section we explored the changing <em>figurations</em>
|
|
|
|
|
|
of key dimensions of algorithmic security vision, in this section we
|
|
|
|
|
|
examine how these figurations <em>configure</em>. For Suchman, working
|
|
|
|
|
|
with configurations highlights “the histories and encounters through
|
|
|
|
|
|
which things are figured <em>into meaningful existence</em>, fixing them
|
|
|
|
|
|
through reiteration but also always engaged in ‘the perpetuity of coming
|
|
|
|
|
|
to be’ that characterizes the biographies of objects as well as
|
|
|
|
|
|
subjects” (Suchman, 2012: 50, emphasis ours) In other words, we are
|
|
|
|
|
|
interested in the practices and tensions that emerge as figurations
|
|
|
|
|
|
become embedded in material practices. We focus on two con-figurations
|
|
|
|
|
|
that emerged in the interviews: the delegation of accountability to
|
|
|
|
|
|
externally managed benchmarks, and the displacement of responsibility
|
|
|
|
|
|
through the reconfiguration of the human-in-the-loop.</p>

<h2>Delegating accountability to benchmarks</h2>
|
|
|
|
|
|
<div data-custom-style="Body Text">
|
|
|
|
|
|
<p>The first configuration is related to the evaluation of the error
|
|
|
|
|
|
rate in the training of algorithmic vision systems: it involves
|
|
|
|
|
|
datasets, benchmark institutions, and the idea of fairness as equal
|
|
|
|
|
|
representation among different social groups. Literature on the ethical
|
|
|
|
|
|
and political effects of algorithmic vision has notoriously focused on
|
|
|
|
|
|
the distribution of errors, raising questions of ethnic and racial bias
|
|
|
|
|
|
(e.g. Buolamwini and Gebru, 2018). Our interviews reflect the concerns
|
|
|
|
|
|
of much of this literature as the pre-emption of error figured
|
|
|
|
|
|
repeatedly in relation to the uneven distribution of error across
|
|
|
|
|
|
minorities or groups. In Diagram 8, Ádám Remport draws how different
|
|
|
|
|
|
visual traits have often led to different error rates. While the general
|
|
|
|
|
|
error metric of an algorithmic system might seem "acceptable," it
|
|
|
|
|
|
actually privileges particular groups, which is invisible when only the
|
|
|
|
|
|
whole is considered. Jeroen van Rest distinguishes such errors from the
|
|
|
|
|
|
inherent algorithmic imprecision in deep machine learning models, as
|
|
|
|
|
|
systemic biases (Diagram 7), as they perpetuate inequalities in the
|
|
|
|
|
|
society in which the product is being developed.</p>

<p>Diagram 8. Ádám Remport describes that facial recognition
|
|
|
|
|
|
technologies are often most accurate with white male adult faces,
|
|
|
|
|
|
reflecting the datasets they are trained with. The FPR is higher with
|
|
|
|
|
|
people with darker skin, children, or women, which may result in false
|
|
|
|

flagging and false arrests.</p>

<p>To mitigate these concerns and manage their risk, many of our

|
|
|

|
interviewees who develop and implement these technologies, externalize
|
|
|
|
|
|
the reference against which the error is measured. They turn to a
|
|
|
|
|
|
benchmark run by the American National Institute of Standards and
|

|
|
Technology (NIST), which ranks facial recognition technologies by

different companies by their error metric across groups. John Riemen,

at the Center for Biometrics of the Dutch police, describes how their

choice for software is driven by a public tender that demands a "top-10"

|
|
|
|
|
|
to an external, and in this case foreign, institution.</p>

<p>We see in this outsourcing of error metrics a form of delegation that
|
|
|
|
|
|
brings about a specific regime of (in)visibility. While a particular
|
|
|
|
|
|
kind of algorithmic bias is rendered central to the NIST benchmark, the
|
|
|
|
|
|
mobilization of this reference obfuscates questions on how that metric
|
|
|
|
|
|
was achieved. That is to say, questions about training data are
|
|
|
|
|
|
invisibilized, even though that data is a known site of contestation.
|
|
|
|
|
|
For example, the NIST benchmark datasets are known to include faces of
|
|
|
|
|
|
wounded people (Keyes, 2019). The Clearview company is known to use
|
|
|
|
|
|
images scraped illegally from social media, and IBM uses a dataset that
|
|
|
|
|
|
is likely in violation of European GDPR legislation (Bommasani et al.,
|
|
|
|
|
|
2022: 154). Pasquinelli (2019) argued that machine learning models
|
|
|
|
|
|
ultimately act as data compressors: enfolding and operationalizing
|
|
|
|
|
|
imagery of which the terms of acquisition are invisibilized.</p>

<p>Attention to this invisibilization reveals a discrepancy between the
|
|
|
|
|
|
developers and the implementers of these technologies. On the one hand,
|
|
|
|
|
|
the developers we interviewed expressed concerns about how their
|
|
|
|
|
|
training data is constituted to gain a maximum false positive rate/true
|
|
|
|
|
|
positive rate (FPR/TPR) ratio, while showing concern for the legality of
|
|
|
|
|
|
the data they use to train their algorithms. On the other hand,
|
|
|
|
|
|
questions about the constitution of the dataset have been virtually
|
|
|
|
|
|
non-existent in our conversations with those who implement software that
|
|
|
|
|
|
relies on models trained with such data. Occasionally this knowledge was
|
|
|
|
|
|
considered part of the developers' intellectual property that had to be
|
|
|
|
|
|
kept a trade secret. A high score on the benchmark is enough to pass
|
|
|
|
|
|
questions of fairness, legitimizing the use of the algorithmic model.
|
|
|
|
|
|
Thus, while indirectly relying on the source data, it is no longer
|
|
|
|
|
|
deemed relevant in the consideration of an algorithm. This illustrates
|
|
|
|
|
|
well how the invisibilization of the “compressed” dataset, in
|
|
|
|
|
|
Pasquinelli’s terms, into a model, with the formalization of guiding
|
|
|
|
|
|
metrics into a benchmark, permits a bracketing of accountability. One
|
|
|
|
|
|
does not need to know how outcomes are produced, as long as the
|
|
|
|
|
|
benchmarks are in order.</p>

<p>The public critique of algorithms has often construed the
|
|
|
|
|
|
<em>human-in-the loop</em> as one of the last lines of defense in the
|
|
|
|
|
|
resistance to automated systems, able to filter and correct erroneous
|
|
|
|
|
|
outcomes (Markoff, 2020). The literature in critical security studies
|
|
|
|
|
|
has however problematized the representation of the security operator in
|
|
|
|
|
|
algorithmic assemblages by discussing how the algorithmic predictions
|
|
|
|
|
|
appear on their screen (Aradau and Blanke, 2018), and how the embodied
|
|
|
|
|
|
decision making of the operator is entangled with the algorithmic
|
|
|
|
|
|
assemblage (Wilcox, 2017). Moreover, the operator is often left guessing
|
|
|
|
|
|
at the working of the device that provides them with information to make
|
|
|
|
|
|
their decision (Møhl, 2021).

<p>What our participants’ diagrams emphasized is how a whole spectrum of
|
|
|
|
|
|
system designs emerges in response to similar questions, for example the
|
|
|
|
|
|
issue of algorithmic bias. A primary difference can be found in the
|
|
|
|
|
|
degree of understanding of the systems that is expected of security
|
|
|
|

operators, as well as their perceived autonomy. Sometimes, the human

|
|
violent incidents is always [on a] human, not the algorithm. The

|
|

with it.”</p>

|
|
|

the final decision. He adds that there should be no fewer than three
|

|
|
|

humans-in-the-loop who operate independently to increase the accuracy of

For the Burglary-Free Neighborhood project in Rotterdam, project manager
|
|
|
|
|
|
Guido Delver draws surveillance as operated by neighborhood residents,
|
|
|
|
|
|
through a system that they own themselves. By involving different
|
|
|
|
|
|
stakeholders, Delver hopes to counter government hegemony over the
|
|
|
|
|
|
surveillance apparatus. However, residents are untrained in assessing
|
|
|
|
|
|
algorithmic predictions raising new challenges. Delver illustrates a
|
|
|
|
|
|
scenario in which the algorithmic signaling of a potential burglary may
|
|
|
|
|
|
have dangerous consequences: “Does it invoke the wrong behavior from the
|
|
|
|
|
|
citizen? [They could] go out with a bat and look for the guy who has
|
|
|
|
|
|
done nothing [because] it was a false positive.” In this case, the worry
|
|
|
|
|
|
is that the erroneous predictions will not be questioned. Therefore, in
|
|
|
|
|
|
Delver’s project the goal was to actualize an autonomous system, “with
|
|
|
|
|
|
as little interference as possible.” Human participation or
|
|
|
|
|
|
“interference” in the operation are potentially harmful. Thus, figuring
|
|
|
|
|
|
the operator — whether police officer or neighborhood resident — as
|
|
|
|
|
|
risky, can lead to the relegation of direct human intervention.</p>

of the system. At times they are configured as an expert in

users who are activated by the alerts generated by the system, and who
