Memory is usually treated like office rent: annoying, expensive, but somehow always assumed to be available until the bill arrives. In search-based AI, that assumption is everywhere. Monte-Carlo Tree Search (MCTS) grows a tree of possible futures, samples outcomes, and gradually spends more attention on branches that look promising. Elegant. Effective. Also rather fond of storage. ...
A prompt is usually a small thing. “White dog.” “Person in a blue jacket.” “Cup on the table.” Nobody hears these phrases and thinks: excellent, time to deploy a large general-purpose language encoder. Yet that is often what modern vision-language segmentation systems do. The visual model may be carefully optimized. The deployment team may obsess over image encoder latency, GPU memory, and batch size. Then the text side sits there, inherited from a larger foundation model stack, quietly burning capacity to understand what is often a noun phrase with a color adjective attached. Very sophisticated machinery, bravely parsing “red car.” Heroic. ...
Privacy is easy to admire in a slide deck. It becomes less elegant when the model begins to behave like a shopping cart with one broken wheel. Federated learning promises a clean bargain: data stay local, clients collaborate, and the central model improves without seeing everyone’s raw records. Add differential privacy, and the promise becomes more formal. Each client update is clipped, noise is injected, and individual influence is bounded. Everyone nods. The architecture looks responsible. ...
MemCtrl: Teaching Small Models What Not to Remember A robot assistant walks through a room. It sees a chair from the front. Then from the side. Then from a slightly worse angle. Then the same chair again, because the camera moved while the robot hesitated. In theory, all of this is “context.” In practice, it is mostly noise wearing a productivity badge. ...
Latency is where elegant AI architectures go to become invoices. A neuro-symbolic system looks clean on a slide: a neural model sees patterns, a symbolic module checks rules, a probabilistic module handles uncertainty, and the final system behaves more reliably than a pure neural model improvising under fluorescent lighting. Lovely. Very architectural. Very responsible. ...
A model can be small and still be badly organized. That is the quiet problem behind a lot of model compression work. We often ask whether a neural network can be pruned without losing too much accuracy. Fair enough. Budgets are real. Memory is not decorative. But the question hides a stronger assumption: that one sparse structure should serve every input equally well. ...
A drone can cover a construction site, a traffic corridor, or a flooded street in minutes. That is the easy part. The harder part is noticing the small object that changes the decision: a person near a road barrier, a tiny vehicle in a dense intersection, a partly hidden target on a high-resolution aerial image. ...
Cores are usually discussed as a performance story. More cores, more parallelism, less latency, happier product manager. Security people, being paid to ruin everyone’s afternoon, usually hear something else: more switching activity, more leakage, more things an attacker can measure. This paper complicates that instinct in a useful way. In Influence of Parallelism in Vector-Multiplication Units on Correlation Power Analysis, Manuel Brosch, Matthias Probst, Stefan Kögler, and Georg Sigl study a very specific question: when a neural-network accelerator processes the same input value across multiple processing elements, each with a different secret weight, what happens to correlation power analysis?1 ...
Battery. It is a wonderfully effective way to end an argument about elegant algorithms. A wearable device may benefit from learning how its surrounding physical system changes over time. It may even need an interpretable equation rather than another black-box prediction. But if one model update consumes more energy than the device stores, theoretical elegance becomes a rather expensive form of decoration. ...
Compression needs a rulebook, not just a diet plan Compression is the least glamorous part of the LLM business until the bill arrives. A model works beautifully in a cloud demo. Then someone asks whether it can run on a device with limited memory, limited energy, limited connectivity, and limited patience. Suddenly the elegant system becomes a logistics problem. Quantize it. Prune it. Shrink it. Hope it still speaks like the original model and not like a sleep-deprived intern summarizing a legal contract from memory. ...
