Table 6: Sizes of the splits of the datasets used in this work. It contains approximately 5M passages (1.5 GiB uncompressed). We implement Baleen using Python 3.7 and PyTorch 1.6 and rely extensively on the HuggingFace We train and test with automatic mixed precision that is built into PyTorch. To train the single-hop retriever used to initiate the supervision procedure of 3.2, we follow the training strategy of Khattab et al. ColBERT model to create training triples, and then we train our retriever (in this case, FLIPR for first-hop) with these triples.

Fox News senior national correspondent William La Jeunesse reports on proposed changes to California's electric bills on'Special Report.' Power saver programs are utility-sponsored demand response initiatives that help reduce electricity usage during periods of peak demand. These programs typically target central air conditioners (AC) and heat pumps, since cooling equipment drives spikes in summer energy demand. In exchange for incentives such as bill credits or rebates, participating homeowners allow the utility to temporarily adjust or cycle their HVAC systems on hot days. I recently received an email from Leah, an HVAC professional based in Rio Rancho, New Mexico.

There is now a large body of techniques, many based on formal methods, for describing and realizing complex robotics tasks, including those involving a variety of rich goals and time-extended behavior. This paper explores the limits of what sorts of tasks are specifiable, examining how the precise grounding of specifications, that is, whether the specification is given in terms of the robot's states, its actions and observations, its knowledge, or some other information,is crucial to whether a given task can be specified. While prior work included some description of particular choices for this grounding, our contribution treats this aspect as a first-class citizen: we introduce notation to deal with a large class of problems, and examine how the grounding affects what tasks can be posed. The results demonstrate that certain classes of tasks are specifiable under different combinations of groundings.

Despite being well researched in many languages, information retrieval has still not received much attention from the Vietnamese research community. This is especially true for the case of legal documents, which are hard to process. This study proposes a new approach for information retrieval for Vietnamese legal documents using sentence-transformer. Besides, various experiments are conducted to make comparisons between different transformer models, ranking scores, syllable-level, and word-level training. The experiment results show that the proposed model outperforms models used in current research on information retrieval for Vietnamese documents.

This reliable, feature-packed air conditioner from GE earned our top honors during testing. The GE Profile Series PHC08LY is a window-mounted air conditioner that blends top-notch cooling capabilities with a variety of unique features, with a bit of style and elegance. During testing, this 8,000 BTU (British Thermal Units) AC unit reduced our 340 square foot test area's temperature by 10 F in only 43 minutes and lowered the room's humidity by 14 percent in the same amount of time. On top of this, it ran (for an air conditioner) quietly. While using the GE Profile Series' Quiet Mode it only put out 49.3 dBA of sound -- that's less noise than an average household refrigerator makes.
