PROBLEMDeep ensembles of MLPs for tabular data often underperform gradient-boosted trees because using identical hyperparameters across all members limits diversity, forcing practitioners to invest significant effort in hyperparameter tuning to extract competitive performance.
APPROACHTabPack constructs an ensemble of MLPs where each member receives a distinct architecture—varying depth, width, and dropout rate—sampled from a predefined distribution. The ensemble is trained efficiently by sharing a common backbone or by jointly optimizing all subnetworks within a single larger model, keeping the training cost comparable to a single large MLP while enabling structural diversity. The final prediction averages outputs from all members, and the hyperparameter assignment is fixed a priori, eliminating per-task tuning.
KEY RESULTSOn standard tabular classification benchmarks (OpenML-CC18), TabPack improves accuracy by 2–5% over homogeneous MLP ensembles and single tuned MLPs, making deep ensembles competitive with tuned XGBoost. In some tasks, it matches or exceeds XGBoost without any hyperparameter search.
BUILDERS TAKEAWAYWhen building deep ensembles for tabular data, inject architectural diversity by varying depth, width, and dropout across members rather than relying solely on random initialization. This can be implemented today by defining a set of distinct MLP configurations and training them jointly with a shared feature extractor or via a multi-branch network, yielding strong out-of-the-box results without extensive tuning.
LIMITATIONSThe method increases model capacity and inference cost relative to a single MLP, and the diversity gains diminish on small datasets or problems where simple feature interactions dominate, making XGBoost still a more efficient default.

Global LLM deployments without KV-cache-aware load balancing suffer tail latency spikes as requests hit cold replicas; GORGO's online tuning jointly optimizes for cache locality, replica load, and network RTT to reduce p95 latency by up to 40% in cross-region settings. This directly impacts SLA compliance for user-facing chatbots and API services distributed across multiple cloud regions.
Robot manipulation policies that fine-tune VLMs end-to-end often destroy the semantic understanding that makes those pretrained models valuable; InternVLA-A1.5 preserves frozen VLM embeddings and learns a latent dynamics model for foresight, achieving compositional generalization to unseen object arrangements. This approach bridges the gap between internet-scale visual knowledge and physical interaction data.
RLVR fine-tuning for reasoning is computationally prohibitive for each new large model because it requires millions of on-policy rollouts; Direct On-Policy Distillation transfers reasoning skills from a smaller, RLVR-trained weak model to a strong model without the target model generating its own trajectories. This can cut training FLOPs by over 50% while preserving reasoning accuracy on benchmarks like MATH and GSM8K.
Tabular deep learning ensembles often underperform gradient-boosted trees because using identical hyperparameters across all MLPs limits diversity; TabPack assigns distinct hyperparameters (depth, width, dropout) per member, improving ensemble accuracy by 2-5% on tabular benchmarks. This makes deep ensembles competitive with XGBoost on structured data tasks like fraud detection and customer churn.
📰 NEWS
The AI industry is shifting its battleground from model size to deployment efficiency, with $3.5B in infrastructure investments signaling that inference cost and latency are becoming the primary competitive moats. New model releases like Fable 5 and ZCode matter less than who can serve them at scale with acceptable margins.
Fable's ability to generate optimized GPU kernels directly from high-level descriptions could commoditize hand-tuned CUDA code, lowering the barrier for custom op development. Meanwhile, analog computation research points to a future where matrix multiplies run orders-of-magnitude more efficiently, though it remains years from practical deployment.
Seedance 2.5's release shows video generation models are iterating fast enough that production pipelines must be designed for model swapability, not fixed checkpoints. OpenAI's incremental GPT-5.6 naming suggests that scaling laws still yield improvements but the leaps are narrowing, making it harder to justify full retraining for each version.
A Nobel laureate joining Anthropic validates that AI-for-science is producing real, high-impact results beyond toy demonstrations, while the continued price drop of open models makes it feasible to run large-scale scientific simulations without cloud vendor lock-in. This accelerates the adoption of LLMs in drug discovery and materials science.
