Ironic then, because if transformers are Bayesian networks then we're using Bayesian networks for non-independent features.

> Abstract: Residual connections with PreNorm are standard in modern LLMs, yet they accumulate all layer outputs with fixed unit weights. This uniform aggregation causes uncontrolled hidden-state growth with depth, progressively diluting each layer's contribution. We propose Attention Residuals (AttnRes), which replaces this fixed accumulation with softmax attention over preceding layer outputs, allowing each layer to selectively aggregate earlier representations with learned, input-dependent weights. To address the memory and communication overhead of attending over all preceding layer outputs for large-scale model training, we introduce Block AttnRes, which partitions layers into blocks and attends over block-level representations, reducing the memory footprint while preserving most of the gains of full AttnRes. [...]

> Abstract: [...] Flash-kmeans introduces two core kernel-level innovations: (1) FlashAssign, which fuses distance computation with an online argmin to completely bypass intermediate memory materialization;

> (2) sort-inverse update, which explicitly constructs an inverse mapping to transform high-contention atomic scatters into high-bandwidth, segment-level localized reductions.

> Furthermore, we integrate algorithm-system co-designs, including chunked-stream overlap and cache-aware compile heuristics, to ensure practical deployability.

> [...] flash-kmeans achieves up to 17.9X end-to-end speedup over best baselines, while outperforming industry-standard libraries like cuML and FAISS by 33X and over 200X, respectively.

With redundancy and idempotency, distributed computation can work.

In order to run computation distributedly with required keys, sharded distributed ledger protocol nodes cost the smart contracts that they execute in a virtual machine with network access limited to in-protocol messages. Each "smart contract" costs money to run redundantly on multiple nodes, and so it should or must have an account with a verifiably-sufficient balance in order to run.

Smart contracts must be uploaded using a private key with a corresponding public key.

Smart contracts are identified by and so are addressed by a hash of their bytecode.

Wool, Dask, and Celery @task don't solve for smart contract output storage costs with redundancy. They don't set up database(s) with replication large enough for each computation step for you. Dask and Celery model and track the state of each executed DAG centrally with logs as trustable as the centralized nodes which are a single point of failure.

Why isn't Docker Swarm - which L2 bridges amongst all nodes without restriction - appropriate for a given application, given the Access Control Lists and cloud (pod,) configuration necessary for e.g. AWS or GCP to prevent budget overflow? Why quota grid users somehow?

Serverless functions must be uploaded/deployed before being run, too. To orchestrate a bunch of web services is to execute the DAG and handle errors due to network, node, and service failures and latency

But then what protocol do the (serverless function) services all implement, so that we don't have to have a hodgepodge of API clients to use all the services in the grid?

With (serverless) functions bound to /URL routes, cost each function and estimate resource requirements to continue to run a function of that cost. To handle just benign resource exhaustion, say, Scale up the databases and/or redundant block storages, change other distributed computation grid parameters for that pod or those pods of resources which service a named, signed function like /api/v1/helloworld_v2?q=select%20* which is creating contention for the costed resources of the organization

On what signals do you scale up or scale down - within a resource budget - to afford fanning out over multiple actually parallel nodes to compute and sign and store the data?
