A new game-changing weapon that uses radio waves to disable enemy electronics and take down multiple drones at once is under development for the UK’s armed forces. A new game-changing weapon that uses radio waves to disable enemy electronics and take down multiple drones at once is under development for the UK’s armed forces. This forms part of work to put the UK’s defence industry on a war footing following the Prime Minister’s announcement last month of an increase to the defence budget to 2.5% of GDP by 2030. An example of a Radio Frequency Directed Energy Weapon (RFDEW), the versatile system can detect, track and engage a range of threats across land, air and sea. The system will be able to effect targets up to 1km away, with further development in extending the range ongoing. It beams radio waves to disrupt or damage the critical electronic components of enemy vehicles causing them to stop in their tracks or fall out of the sky. RFDEW technology can be mounted on a variety of military vehicles and uses a mobile power source to produce pulses of Radio Frequency energy in a beam that can rapidly fire sequenced shots at individual targets or be broadened to simultaneously engage all threats within that beam. At only 10p per shot fired, the RFDEW beam is a significant cost-effective alternative to traditional missile-based, air defence systems, capable of downing dangerous drone swarms with instant effect. The high level of automation also means the system itself can be operated by a single person. This technology can offer a solution to protection and defence of critical assets and bases. The advanced technology is being developed by a joint team from the Defence Science and Technology Laboratory (Dstl) and Defence Equipment & Support (DE&S), working with UK industry under Project Hersa. The next steps for RFDEW is undergoing extensive field testing with British soldiers over the summer. #military #defense #defence #militaryleak https://lnkd.in/gedTrkrc

A Practical Review of Mechanistic Interpretability for Transformer-Based Language Models (George Mason University, July 2024) Paper: https://lnkd.in/gYTCnZ3Z Abstract: "Mechanistic interpretability (MI) is an emerging sub-field of interpretability that seeks to understand a neural network model by reverse-engineering its internal computations. Recently, MI has garnered significant attention for interpreting transformer-based language models (LMs), resulting in many novel insights yet introducing new challenges. However, there has not been work that comprehensively reviews these insights and challenges, particularly as a guide for newcomers to this field. To fill this gap, we present a comprehensive survey outlining fundamental objects of study in MI, techniques that have been used for its investigation, approaches for evaluating MI results, and significant findings and applications stemming from the use of MI to understand LMs. In particular, we present a roadmap for beginners to navigate the field and leverage MI for their benefit. Finally, we also identify current gaps in the field and discuss potential future directions."

In 1905 Einstein wrote a paper where he asked: "Does the inertia of a body depend upon its energy content?" From this question, he wrote a 3 page paper where he derived the now-famous 𝐸=𝑚𝑐^2 He proved that energy and mass are interchangeable. This simple equation revolutionized our understanding of physics. A simple yet amazing paper:

Coherent Population Trapping (CPT) is a quantum phenomenon that occurs in atomic systems when certain energy levels of atoms are manipulated to create a population of atoms that are "trapped" in a coherent superposition of quantum states.

In a large-scale war, winning the economics of battle becomes just as important as winning the battle itself. ⬇️ A future-ready Army will need to judiciously use its arsenal—cost efficiency will be just as important as neutralising a selected target. Forbes published an intriguing op-ed late last year looking at the use of first-person view (FPV) drones to deliver small high explosives such as anti-tank warheads usually fired from shoulder launchers. While a target like a tank might take numerous drones to disable and destroy, an FPV and a grenade cost as little as $1k USD and have a range of ~ 10 kilometres from the operator.   https://lnkd.in/gEv7VbRy Defense One provides some insight into the costs of artillery, which is in the midst of a resurgence courtesy of the return of a large-scale attritional conflict in Ukraine. The humble 155mm high-explosive round costs between $3k and $8k USD each, sending 9 kg of high explosive ~30 km downrange from artillery guns such as the in-service M777 and soon-to-be-acquired AS9 Huntsman. Note that even a simple mission would expend close to 21 rounds with a cost to neutralise $63k (excluding shipping and artillery operating costs). Center for Strategic and International Studies (CSIS) provides US military costs for guided missiles that can be fired from Australia's soon-to-be-acquired HIMARs launchers: A single GLMRS missile, which can be fired up to 70 km, costs $160k USD each (excluding shipping and artillery operating costs) to deliver a 90-kilogram high-explosive warhead. Stepping up to the ATACMS missile with a range of 300km costs ~$1 million USD each (excluding shipping and artillery operation costs) to deliver ~ a 200-kilogram high-explosive warhead. Now, an FPV, 155mm HE round, GLMRS, and ATACMS missile each have efficient and effective use cases. But what is clear is that targeting in the next war will need to take into account the costs of each option. So now, over to industry. Are there cheaper ways to deliver a high explosive effect at a similar range? Methods of manufacture, benefits of scale, and more cost-effective materials - can we be more brilliant at the basics, or is there another way to revolutionise the battle? #dronewar #revolutionisewar #futureready #futurearmy #fpvdrone #defence #antiattack Ben Dullroy Steve Baxter Jake Bostock Sean Singleton Mick Ryan, AM Keirin Joyce Peta Ellis Max Quinlan-ward Alexandra Grigg More links in comments.

SEAL: A Dual-Encoder Framework Enhancing Hierarchical Imitation Learning with LLM-Guided Sub-Goal Representations Researchers from the University of Alberta and a prominent institution in Hong Kong specializing in science and technology have developed SEAL, a new hierarchical imitation learning framework that utilizes LLMs for generating semantically meaningful sub-goals and pre-labeling states without needing prior knowledge of task hierarchies. SEAL features a dual-encoder system, combining LLM-guided supervised learning with unsupervised Vector Quantization (VQ) for robust sub-goal representation. It also includes a transition-augmented low-level planner to manage sub-goal transitions effectively. Experiments show that SEAL surpasses existing HIL methods, particularly in complex tasks with limited expert datasets....
