Tomb Raider: Legacy of Atlantis is a vivid, high-pace remake of a classic
This time, her character is positioned between the Survivor trilogy of the last decade and her iconic debut in 1996. At Summer Game Fest 2026, Crystal Dynamics and Flying Wild Hog shared the first gameplay demo, with Unreal Engine 5 adding vivid detail and lushness to Lara's travails. The developers made a clever choice, centering the demo on an early part of the original game. Set in the Peruvian mountainside, my playthrough included a giant cog puzzle I remember from playing the original. There were also several shootouts with a herd of dinosaurs, the same vivid red velociraptor-adjacent creatures from 1996).

Here we derive Equation 8 for 0 and out = > 0. Since ESN(ยต, 2,0) = NR(ยต,), we can obtain Equation 4 for ID activation by specializing the result to =0 . We begin with a useful lemma. Let X ESN(0, 2,) and let a b 0, 0 c d. Then P(a X b)= (1+) h The result for P(c X d) follows analogously. For the reader's convenience, we summarize in detail a few common techniques for defining OOD scores that measure the degree of ID-ness on the given sample. All the methods derive the score post hoc on neural networks trained with in-distribution data only.
Yosemite's glowing, golden waterfall is flowing again
Environment Yosemite's glowing, golden waterfall is flowing again The annual natural phenomenon event is expected to last until February 26. Breakthroughs, discoveries, and DIY tips sent six days a week. As if California's Yosemite National Park wasn't magical enough, its famous El Capitan rock formation is graced with an exhilarating phenomenon every February. The Horsetail Fall--a waterfall that falls across the formation's eastern side--can take on an otherworldly gleam during the latter part of the month. During those gorgeous moments, the water flow looks like a stream of gold hurtling down the rock face, and it's hard to believe that it's just nature doing its thing.
mmE5: Improving Multimodal Multilingual Embeddings via High-quality Synthetic Data
Chen, Haonan, Wang, Liang, Yang, Nan, Zhu, Yutao, Zhao, Ziliang, Wei, Furu, Dou, Zhicheng
Multimodal embedding models have gained significant attention for their ability to map data from different modalities, such as text and images, into a unified representation space. However, the limited labeled multimodal data often hinders embedding performance. Recent approaches have leveraged data synthesis to address this problem, yet the quality of synthetic data remains a critical bottleneck. In this work, we identify three criteria for high-quality synthetic multimodal data. First, broad scope ensures that the generated data covers diverse tasks and modalities, making it applicable to various downstream scenarios. Second, robust cross-modal alignment makes different modalities semantically consistent. Third, high fidelity ensures that the synthetic data maintains realistic details to enhance its reliability. Guided by these principles, we synthesize datasets that: (1) cover a wide range of tasks, modality combinations, and languages, (2) are generated via a deep thinking process within a single pass of a multimodal large language model, and (3) incorporate real-world images with accurate and relevant texts, ensuring fidelity through self-evaluation and refinement. Leveraging these high-quality synthetic and labeled datasets, we train a multimodal multilingual E5 model mmE5. Extensive experiments demonstrate that mmE5 achieves state-of-the-art performance on the MMEB Benchmark and superior multilingual performance on the XTD benchmark. Our codes, datasets and models are released in https://github.com/haon-chen/mmE5.
Robust Multi-bit Text Watermark with LLM-based Paraphrasers
Xu, Xiaojun, Jia, Jinghan, Yao, Yuanshun, Liu, Yang, Li, Hang
We propose an imperceptible multi-bit text watermark embedded by paraphrasing with LLMs. We fine-tune a pair of LLM paraphrasers that are designed to behave differently so that their paraphrasing difference reflected in the text semantics can be identified by a trained decoder. To embed our multi-bit watermark, we use two paraphrasers alternatively to encode the pre-defined binary code at the sentence level. Then we use a text classifier as the decoder to decode each bit of the watermark. Through extensive experiments, we show that our watermarks can achieve over 99.99\% detection AUC with small (1.1B) text paraphrasers while keeping the semantic information of the original sentence. More importantly, our pipeline is robust under word substitution and sentence paraphrasing perturbations and generalizes well to out-of-distributional data. We also show the stealthiness of our watermark with LLM-based evaluation. We open-source the code: https://github.com/xiaojunxu/multi-bit-text-watermark.
Deep Learning Evidence for Global Optimality of Gerver's Sofa
Leng, Kuangdai, Bi, Jia, Cha, Jaehoon, Pinilla, Samuel, Thiyagalingam, Jeyan
The Moving Sofa Problem, formally proposed by Leo Moser in 1966, seeks to determine the largest area of a two-dimensional shape that can navigate through an $L$-shaped corridor with unit width. The current best lower bound is about 2.2195, achieved by Joseph Gerver in 1992, though its global optimality remains unproven. In this paper, we investigate this problem by leveraging the universal approximation strength and computational efficiency of neural networks. We report two approaches, both supporting Gerver's conjecture that his shape is the unique global maximum. Our first approach is continuous function learning. We drop Gerver's assumptions that i) the rotation of the corridor is monotonic and symmetric and, ii) the trajectory of its corner as a function of rotation is continuously differentiable. We parameterize rotation and trajectory by independent piecewise linear neural networks (with input being some pseudo time), allowing for rich movements such as backward rotation and pure translation. We then compute the sofa area as a differentiable function of rotation and trajectory using our "waterfall" algorithm. Our final loss function includes differential terms and initial conditions, leveraging the principles of physics-informed machine learning. Under such settings, extensive training starting from diverse function initialization and hyperparameters is conducted, unexceptionally showing rapid convergence to Gerver's solution. Our second approach is via discrete optimization of the Kallus-Romik upper bound, which converges to the maximum sofa area from above as the number of rotation angles increases. We uplift this number to 10000 to reveal its asymptotic behavior. It turns out that the upper bound yielded by our models does converge to Gerver's area (within an error of 0.01% when the number of angles reaches 2100). We also improve their five-angle upper bound from 2.37 to 2.3337.
