How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to scaling is scale.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Machine learning

Scaling as loss falling predictably with compute, data, and parameters

The empirical regularity that a language model's test loss falls as a power law in the number of parameters, the size of the training set, and the compute spent, over several orders of magnitude, with architecture mattering little by comparison. Kaplan and colleagues fixed the laws in 2020 and drew the practical conclusion that compute is best spent on larger models trained on relatively few tokens. Hoffmann and colleagues revised the recipe in 2022 with Chinchilla: at a fixed compute budget parameters and tokens should grow together, so earlier models were undertrained. Sutton's 2019 essay gave the programme its creed, general methods that use more computation beat methods built on human knowledge, and researchers have learned this lesson repeatedly and reluctantly. The construct is a fitted exponent, and its use is deciding how to spend the next budget.[1][2][3]

Unit
A family of models, across orders of magnitude of compute, data, and parameters
Recovery means
Not applicable, a curve that flattens is a broken law, not a lost state
Measured by
Held-out cross-entropy against log parameters, log tokens, and log FLOPs; the fitted exponents and the compute-optimal frontier

Computer systems

Scaling as adding resources and getting proportional throughput

The ability of a system to handle more work when given more hardware, and the limits on that ability. Amdahl argued in 1967 that the serial fraction of a program caps the speedup any number of processors can deliver; Gustafson replied in 1988 that in practice the problem grows with the machine, so the serial fraction shrinks and speedup can stay near linear. Hill's 1990 note observed that the field used scalability without a definition and offered one in terms of efficiency as processors are added. Practice splits the word again: vertical scaling adds capacity to one machine, horizontal scaling adds machines. The unit is a workload on a system, and the criterion is throughput or latency as a function of resources.[4][5][6]

Unit
A workload on a system, as processors, nodes, or capacity are added
Recovery means
Not applicable, a system that stops scaling is re-architected, not recovered
Measured by
Speedup and efficiency against processor count; throughput and tail latency under load; the serial fraction

Entrepreneurship & management

Scaling as growing a venture faster than its costs

The growth of an organisation's activity, reach, or impact at a rate that outpaces the growth of its resources, and the organisational changes that make such growth survivable. Shepherd and Patzelt's 2022 call for research fixed the academic construct: scaling is distinct from growth in that it concerns how the organisation replicates and spreads what works, and it applies to social impact as well as revenue. Hoffman and Yeh's 2018 Blitzscaling is the practitioner version, prioritising speed over efficiency in the face of uncertainty, accepting operational chaos to capture a market before rivals do. The unit is a firm, the clock is years, and the measure is customers or revenue per employee, not loss per FLOP.[7][8]

Unit
A venture or programme, over years of growth
Recovery means
Not applicable, a venture that fails to scale contracts or exits, and the literature on turnaround is separate
Measured by
Revenue, users, or beneficiaries against headcount and capital; survival; replication of a model across sites

Psychometrics

Scaling as assigning numbers to objects by rule

The assignment of numerals to objects or events according to a rule, and the question of which arithmetic the resulting numbers will bear. Stevens fixed the vocabulary in 1946: nominal, ordinal, interval, and ratio scales, each defined by the transformations that leave its information intact and each licensing a different set of statistics. Thurstone's 1927 law of comparative judgment showed how to build an interval scale from pairwise choices, and Likert's 1932 summated ratings gave the survey item its standard form. Kruskal's 1964 multidimensional scaling recovers a spatial configuration from judged similarities so that distances reproduce the data as well as a monotone fit allows. Scaling here is measurement itself (nothing gets bigger) and the field's disputes are about whether a sum of ratings is interval or only ordinal.[9][10][11][12]

Unit
A set of objects or people, mapped to numbers on a scale
Recovery means
Not applicable
Measured by
Fit of the scale to the data, stress in multidimensional scaling, item and person fit in latent-trait models, reliability of a summated score

Biology

Scaling as how traits change with body size

The relationship between an organism's size and its other properties, usually a power law with an exponent that is not one. Kleiber found in 1932 that metabolic rate across mammals rises as body mass to the three-quarter power, not the two-thirds that surface area would predict, and the exponent has held from mice to elephants. West, Brown, and Enquist derived it in 1997 from the geometry of branching transport networks (a fractal supply system that fills space and minimises the energy of distribution) and predicted quarter-power scaling for heart rate, lifespan, and growth. The unit is a species or an individual on a log–log plot, and the exponent is a fact about physiology that a theory has to earn.[13][14]

Unit
A trait against body mass, across individuals or species
Recovery means
Not applicable
Measured by
Slope of the log–log regression of the trait on mass; departures from the predicted quarter-power exponents

Statistical physics

Scaling as invariance under a change of length scale

The behaviour of a system that looks the same at every magnification, so that its properties near a critical point follow power laws whose exponents depend only on dimension and symmetry, not on the material. Kadanoff's 1966 block-spin argument gave the picture: group neighbouring spins into blocks, treat the blocks as spins, and at the critical temperature the description does not change. Wilson turned the picture into the renormalisation group and his 1979 account for a general audience explains why fluctuations at every length scale must be handled together and why unrelated systems share exponents. Scaling here is a symmetry, the exponents are universal, and a scaling law is a statement about what happens when the ruler changes.[15][16]

Unit
A many-body system near a critical point, across length scales
Recovery means
Not applicable
Measured by
Critical exponents from susceptibility, correlation length, and order parameter; data collapse onto a scaling function
