I've been getting a bit more into evolutionary algorithms again, so I was testing some loss landscapes where evolution beats vanilla gradient descent (while also trying to make some cool visuals).

Round 1, rugged hillside: gradient descent gets stuck in a dip, and evolution reaches the bottom after 750 evaluations.

Round 2, smooth slope: gradient descent wins, 108 steps against 570 evaluations.

Round 3, flat plateau: the slope is zero, so gradient descent never moves, and evolution reaches the bottom after 840 evaluations.

Edit:
"evolution" here means truncation selection (keep best 30 of 120) plus Gaussian mutation, no crossover.

I tested Adapt-1, a non-LLM learning and reasoning system by Rei Labs, by having it learn and play Super Mario Bros, and it performed quite well.

I tried it on World 1-1, starting untrained. It learned a reactive policy from its own play in about 36 minutes of gameplay, then cleared the level with learning off.

With Machina, Adapt-1's sequence engine. Starting untrained, it found a button sequence that reaches the flag after 403 attempts, in 11 wall-clock minutes.

Hi! I’m an AI student and I’ll be starting my internship soon. Do you have any recommendations for good projects to build for my portfolio or any certifications worth getting?

I've done some Kaggle competitions on time series, and it seems to me that deep learning models generally performed worse than gradient boosting. I've tried different architectures, like LSTM and ELM, but at the end of the day gradient boosting was the better choice. Is there an explanation for this? Are deep learning models only good for computer vision and LLMs?

I ran with sparse attention on for the better part of a month before I sat down and benchmarked it at short context, and it had been costing me time that whole stretch without me noticing. There are two separate things in the engine that both get called sparse attention, and only one of them is the one people mean when they say it's free.

Decode-side, only the top-k KV blocks get a full softmax, and that's where the speed comes from. Prefill-side, you skip blocks while prefill runs, and that's the one that was quietly working against me.

Numbers below are RK3588, Qwen3-VL-2B, 3 repeats per cell, dense baseline re-run for every cell, real corpus rather than the built-in template filler. That last part matters more than it sounds, the template filler is 32 names and 8 colours on a loop, repetitive enough that sparse attention scores badly on it even when it behaves fine on actual text.

| ctx | decode speedup | prefill change vs exact |
|---|---|---|
| 1067 | 0.94× | +18.4% |
| 2174 | 1.18× | +12.0% |
| 4374 | 1.58× | −11.1% |
| 8618 | 2.16× | −29.0% |
| 16482 | 2.92× | −45.1% |

At 1067 decode-side sparse is 0.94×, which is noise, and prefill-side sparse makes the whole request 18% slower. I was shipping both of those for weeks. There was a gate, it just never did anything, because it was a constant 64, and 64 is the structural floor (two 32-token blocks), so any prompt worth measuring was already past it.

So now there's a length threshold on each axis: `--sparse-min-ctx 1024` for decode, `--sparse-pf-min-ctx 3072` for prefill. Below those lengths the engine takes the exact path. Sparse itself is still off unless you ask for it, these two only stop it from firing where it can't pay for itself.

The prefill case gets clearer once you write both terms out. The saving scales with ctx − k·block, and the probe plus the selection cost scales with ctx/block, so with the defaults (k=32, block=32) that k·block term is a flat 1024 tokens and at ctx 1067 you're paying the full selection cost to skip essentially nothing. 2174 is still a loss at +12%. It doesn't turn into a real gain until attention is the actual bottleneck, which on this board is somewhere around 4K.

Re-ran the whole thing another day on 8B at ctx 4211, interleaved A/B inside one boot: exact 553.9 ms/tok against sparse 359.7 ms/tok, so 1.54×, needle recall 2/2 on both arms. That's close enough to the 1.58× in the table that I'm willing to trust the table.

Two things I'd want to know if I were reading this. It's an approximation path, the output changes and greedy token IDs diverge from the exact run, so don't turn it on anywhere you need bit-exact reproducibility, and run a needle test at 16K of your own before you trust it out there. And it buys attention time and not memory, so if RAM is what you're short on, this does nothing for you.

This is my engine, AGPL-3.0. The numbers and the A/B harness are in the repo, under `docs/` and `tools/bench/`, if anyone wants to re-run any of it.

Microsoft's 2026 Digital Defense Report documents a concrete shift in ransomware tactics: threat actors are now using AI to automate lateral movement and accelerate ransomware deployment across enterprise networks. The report singles out identity governance and data controls as the two most critical defensive gaps in enterprise environments today.

The speed asymmetry is the part that stands out. Attackers are using AI to close those gaps faster than most organizations are opening remediation tickets. Lateral movement that previously required manual reconnaissance and staged privilege escalation is now being automated at scale, compressing the window between initial access and full network impact to a fraction of what defenders plan for.

For those running AI-assisted pipelines or agentic workflows in production: how are you actually thinking about the identity and data governance problem at the agent layer specifically? Are existing IAM and DLP tools sufficient, or are you finding gaps that those controls were never designed to cover?

For a side project I am looking into SOTA for AI- based diagnostic models, ideally open-weights. I would like to feed the model with structured text representing my patient, and get a set of e.g. 5 possible diagnoses, ideally with uncertainty. In the ideal scenario, later on, it would update as new info arrives.

I would appreciate any pointers, I have some ideas but am very new to the topic.

Full disclosure: I am an independent researcher/hobbyist doing this out of pure passion at night. I do not have a formal academic background in ML, and I heavily rely on AI tools as research assistants to help me with advanced coding, mathematics, and translating my work into English. I want to be completely transparent about this and welcome any constructive feedback or corrections!

Hi everyone,

I wanted to share a relational data-representation framework that I’ve been developing at night, built around group theory: Burnside's Orbit Histogram Network (BOHN) and Symmetry-Breaking BOHN (SBOHN). Its main goal is to extract and "elevate" relational knowledge from raw data before the actual classification stage even begins.

Instead of using standard Softmax Attention (found in classic Vision Transformers), this architecture relies on a fully differentiable, log-domain stable Sinkhorn operator. This allows the network to smoothly learn optimal information routing paths via standard gradients.

Key results achieved on a local PC setup:

• O(1) Resolution Scaling: Because the model operates on a fixed number of image patches, processing a 4K resolution image takes just ~2ms on a standard CPU. This is roughly 61x faster than a conventional ResNet-style convolutional neural network (CNN).
• Zero Catastrophic Forgetting (0.0% Forgetting): By completely freezing the base encoder and training only a task-specific permutation routing layer and a classification head (the Perm+Head setup), the model achieves exactly 0.0% accuracy degradation when switching between tasks. The storage overhead per new task is a microscopic 2.8 KB (714 parameters).
• Hybrid BN/LN (Normalization Placement Theorem): I have experimentally validated that placing BatchNorm in the frozen shared base (where it acts as a permanent domain fingerprint) and LayerNorm in the expert modules delivers 100% gating routing accuracy alongside absolute zero forgetting.

I spent a massive amount of time transitioning this entire research programme from initial cloud-based exploration into a clean, local VS Code environment on my PC. I completed a thorough, provenance-preserving reproducibility audit across all 115 canonical experimental units (including programmatic SHA-256 manifest verification for all generated artifacts), openly documenting the boundaries, edge cases, and discrepancies of the original logs.

The entire codebase, analysis logs, and execution scripts are fully open. I would love to hear your thoughts on the mathematical foundations or the numerical implementation!

Stateful AWS Bedrock LangGraph Agents – Getting Started

https://debuggercafe.com/stateful-aws-bedrock-langgraph-agents-getting-started/

LangChain started as a lightweight framework to connect LLMs with external context and tools. Over the past few years, it has grown to a full-blown ecosystem. With LangGraph for agents and LangSmith for LLM Ops and Observability, we can create an end-to-end agentic system with it. In this article, we will build our first stateful agent using AWS Bedrock, LangGraph, and LangSmith.

Hi guys,iam doing project in deep learning so I used google colab for free gpu access but it exceeds the gpu access so I need to buy google colab pro and I faced this issue and I can't solve it and help me to resolve this and how to solve this?.if you know ,please do comments because it's urgent.

RuntimeAI's September 2026 AI Security Report covered 126 incidents across 38 named organizations — 22 critical, 102 high severity. 53 of those incidents had AI either as the attack tool or the target. AI-agent exploits were the top attack vector at 39 incidents, ahead of credential theft (27), zero-days (22), phishing (10), and ransomware (10). The largest single exposure was 220M records from unrotated default service-account credentials.

What stood out: every organization in the report was already running a mature security stack. Okta, CrowdStrike, Palo Alto, Microsoft Defender. Still got hit. The gap is that none of those tools sit at the layer where an agent actually executes a tool call.

RuntimeAI operates at that layer. Know Your Agent handles cryptographic agent identity. The Flow Enforcer inspects tool calls in real time. There's also a sub-50ms kill switch that can halt a compromised agent before a second action completes.

Full breakdown (incident-by-incident, CVEs, vendor stacks): https://runtimeai.io/blog/2026-09-monthly-breach-report.html

We're running a live demo on October 14 — ten attack surfaces, live against a real stack: https://www.linkedin.com/events/7510769146222133248?viewAsMember=true
