What they believe
-
Pruning cuts the parameters of a trained network by over 90% without costing accuracy, so inference gets smaller and faster for free.
Neural network pruning techniques can reduce the parameter counts of trained networks by over 90%, decreasing storage requirements and improving computational performance of inference without compromising accuracy.

Pruning cuts the parameters of a trained network by over 90% without costing accuracy, so inference gets smaller and faster for free.
Neural network pruning techniques can reduce the parameter counts of trained networks by over 90%, decreasing storage requirements and improving computational performance of inference without compromising accuracy.
Frankle & Carbin, "The Lottery Ticket Hypothesis: Finding Sparse, Trainable Neural Networks" (arXiv) Said 9 Mar 2018
The saving pruning offers is only ever at inference, because the sparse architectures it produces are hard to train from the start.
However, contemporary experience is that the sparse architectures produced by pruning are difficult to train from the start, which would similarly improve training performance.
Frankle & Carbin, "The Lottery Ticket Hypothesis: Finding Sparse, Trainable Neural Networks" (arXiv) Said 9 Mar 2018
Pruning does not merely shrink a network; it uncovers subnetworks whose original initialization was what made them trainable at all.
We find that a standard pruning technique naturally uncovers subnetworks whose initializations made them capable of training effectively.

A winning ticket wins on its initial weights: the connections it keeps started at values that happen to make training work.
The winning tickets we find have won the initialization lottery: their connections have initial weights that make training particularly effective.
Frankle & Carbin, "The Lottery Ticket Hypothesis: Finding Sparse, Trainable Neural Networks" (arXiv) Said 9 Mar 2018
A small enough winning ticket learns faster than the network it was cut out of, and ends up more accurate than it.
Above this size, the winning tickets that we find learn faster than the original network and reach higher test accuracy.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.

- Thanks @MarkLevineNYC! We're incredibly excited to continue making NYC *the* center of AI research. NJ is 2-3 months behind NYC, the Peninsula is 4-7 months behind NYC, while SF is 12+ months behind, and other places are even worse. 21 Oct 2026
- Great conversation with @BrendanFoody talking about the main bottleneck to enterprise adoption of AI and AGI: knowing whether AI is doing what you want it to. The hard part is creating a measurable specification for qualitative tasks in the real data context, i.e., an eval. 21 Oct 2026
- So thrilled for @InspiredCap’s new fund! I’m excited that another generation of companies will get to benefit the same phenomenal advice and unwavering support that MosaicML did. 20 Oct 2026

Some people here publish in a language other than English. Where they do, this site shows a machine translation beneath the post, in this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the serif above is exactly what the person published, and it is what to quote them on. A translation can be wrong in ways that matter, especially about tone.
Only the post's own words are translated. A quoted post, a linked article and a belief on korrents.com are left in their original language.
