Apple's Siri relaunch is reportedly behind schedule
Samsung Galaxy Unpacked 2026 is Feb. 25 Valve's Steam Machine: Everything we know The company is going to release its capabilities in portions over future software updates, according to Bloomberg. Apple's long-delayed AI-powered Siri redesign may not be rolling out this year, at least in the way the company had planned. According to Mark Gurman, Apple found problems with its software upon testing, such as the virtual assistant taking too long to accomplish tasks or even not processing queries properly altogether. Siri's new version was also reportedly so sluggish during testing that its developers believed Apple would have to push back its launch by months. Instead of releasing the redesigned assistant in March as was previously reported, Gurman says Apple will roll out its capabilities piecemeal over future software updates.
Novel positional encodings to enable tree-based transformers
Motivated by this property, we propose a method to extend transformers to tree-structured data, enabling sequence-totree, tree-to-sequence, and tree-to-tree mappings. Our approach abstracts the transformer'ssinusoidal positional encodings, allowing ustoinstead useanovel positional encoding scheme to represent node positions within trees.
Supplementary Material: Segment Anything in High Quality
In this supplementary material, Section 1 first presents the additional experimental analysis of our HQ-SAM, including more zero-shot transfer comparisons to SAM on both image and video benchmarks. SAM vs. HQ-SAM on V arious Backbones In Table 1, we provide a comprehensive comparison Table 2: Results on Y ouTubeVIS 2019 validation set and HQ-YTVIS test set using ViT -L based SAM. In Table 2, HQ-SAM achieves consistent gains of 1.4 points in Tube Mask AP, Robustness to Input Box Prompts In Table 4, we compare HQ-SAM to SAM by adding various scales of noises to the input ground truth box prompts. "center" point of Ground Truth (GT) masks, which is at a maximal value location in a mask's interior Results not obtained in a zero-shot manner (i.e. the training HQ-SAM improves over SAM, but still cannot achieve fully correct mask prediction. HQ-SAM produces significantly more accurate boundaries.
How can robots acquire skills through interactions with the physical world? An interview with Jiaheng Hu
How can robots acquire skills through interactions with the physical world? One of the key challenges in building robots for household or industrial settings is the need to master the control of high-degree-of-freedom systems such as mobile manipulators. Reinforcement learning has been a promising avenue for acquiring robot control policies, however, scaling to complex systems has proved tricky. In their work SLAC: Simulation-Pretrained Latent Action Space for Whole-Body Real-World RL, and introduce a method that renders real-world reinforcement learning feasible for complex embodiments. We caught up with Jiaheng to find out more.
