Therefore, many existing SLP vectorization schemes are driven by hand-crafted heuristics (Liu et al., 2012;

In this section, we derive a lower bound for the trace of the covariance of the PG estimator in environments with stochastic dynamics. Let us assume that the initial policyπ(ai|si) follows the uniform distribution such thatπ(ai = 1|si) = π(ai = +1|si) = 12 for alli. Its optimal policy fort, πtθf(t|s), should producet x because otherwise it has the risk of ending up with ν reward, which is not an optimum. Since FiGAR-C is unaware of underlying state changes, its best strategy is to shorten the duration ofactions tobemoreresponsive. In VPG, we do not use any technique for variance reduction such asvalue functions and reward-to-go policygradient; hence, the formula for its gradient estimator is identical to Equation (3).

Enterprise environments contain a heterogeneous, rapidly growing collection of internal artifacts related to code, data, and many different tools. Critical information for assessing privacy risk and ensuring regulatory compliance is often embedded across these varied resources, each with their own arcane discovery and extraction techniques. Therefore, large-scale privacy compliance in adherence to governmental regulations requires systems to discern the interconnected nature of diverse artifacts in a common, shared universe. We present Privacy Artifact ConnecT or (PACT), an embeddings-driven graph that links millions of artifacts spanning multiple artifact types generated by a variety of teams and projects. Powered by the state-of-the-art DRAGON embedding model, PACT uses a contrastive learning objective with light fine-tuning to link artifacts via their textual components such as raw metadata, ownership specifics, and compliance context. Experimental results show that PACT's fine-tuned model improves recall@1 from 18% to 53%, the query match rate from 9.6% to 69.7% when paired with a baseline AI agent, and the hitrate@1 from 25.7% to 44.9% for candidate selection in a standard recommender system.

Satisfiability Modulo Theory (SMT) solvers have advanced automated reasoning, solving complex formulas across discrete and continuous domains. Recent progress in propositional model counting motivates extending SMT capabilities toward model counting, especially for hybrid SMT formulas. Existing approaches, like bit-blasting, are limited to discrete variables, highlighting the challenge of counting solutions projected onto the discrete domain in hybrid formulas. We introduce pact, an SMT model counter for hybrid formulas that uses hashing-based approximate model counting to estimate solutions with theoretical guarantees. pact makes a logarithmic number of SMT solver calls relative to the projection variables, leveraging optimized hash functions. pact achieves significant performance improvements over baselines on a large suite of benchmarks. In particular, out of 14,202 instances, pact successfully finished on 603 instances, while Baseline could only finish on 13 instances.

On Sunday, the world's governments made a series of commitments to transform global governance at the United Nations Summit of the Future in New York. The ambitiously named summit was described as a "once-in-a-generation opportunity" to "forge a new global consensus on what our future should look like". Indeed, we are at a critical time when change is urgently needed. The world faces "a moment of historic danger", with increasingly imminent risks – from nuclear war to a planetary emergency, from persistent poverty and widening inequality to the unhindered advancement of artificial intelligence – threatening humanity's very existence. These are global challenges that cannot be solved purely at the national level: The people of the world need – and deserve – better coordinated global action.

With the advent of large foundation model based planning, there is a dire need to ensure their output aligns with the stakeholder's intent. When these models are deployed in the real world, the need for alignment is magnified due to the potential cost to life and infrastructure due to unexpected faliures. Temporal Logic specifications have long provided a way to constrain system behaviors and are a natural fit for these use cases. In this work, we propose a novel approach to factor in signal temporal logic specifications while using autoregressive transformer models for trajectory planning. We also provide a trajectory dataset for pretraining and evaluating foundation models. Our proposed technique acheives 74.3 % higher specification satisfaction over the baselines.

BRUSSELS (AP) -- European Union lawmakers approved Wednesday a major revamp of the bloc's migration laws, hoping to end years of division over how to manage the entry of thousands of people without authorization and deprive the far right of a vote-winning campaign issue ahead of June elections. In a series of 10 votes, members of the European Parliament endorsed the regulations and policies that make up the Pact on Migration and Asylum. The reforms address the thorny issue of who should take responsibility for migrants when they arrive and whether other EU countries should be obliged to help. The proceedings were briefly interrupted by a small but noisy group of demonstrators in the public gallery who wore shirts marked "this pact kills" and shouted "vote no!" European Commissioner for Home Affairs Ylva Johansson, is embraced after Members of the European Parliament participated in a series of votes during a plenary session at the European Parliament in Brussels, Wednesday, April 10, 2024.

Fox News correspondent Gillian Turner has the latest on the presidents focus amid calls for an impeachment inquiry on Special Report. The U.S. and U.K. joined more than a dozen countries to unveil a new artifical intelligence agreement aimed at preventing rogue actors from abusing the technology, though not all experts are sold on how useful the pact will be. "This is really more of an agreement of intent than actual substance," Phil Siegel, founder of the Center for Advanced Preparedness and Threat Response Simulation, told Fox News Digital. Siegel's comments come after what a U.S. official described as the first ever detailed agreement on AI safety was unveiled Sunday, according to a report from Reuters, putting measures in place that are meant to create AI systems that are "secure by design." Vice President Kamala Harris watches President Biden sign an executive order during an AI event at the White House on Oct. 30, 2023.

The world's governments have taken note of generative AI's potential for massive disruption and are acting accordingly. European Commission (EC) industry chief Thierry Breton said Wednesday that it would work with Alphabet on a voluntary pact to establish artificial intelligence ground rules, according to Reuters. Breton met with Google CEO Sundar Pichai in Brussels to discuss the arrangement, which will include input from companies based in Europe and other regions. The EU has a history of enacting strict technology rules, and the alliance gives Google a chance to provide input while steering clear of trouble down the road. The compact aims to set up guidelines ahead of official legislation like the EU's proposed AI Act, which will take much longer to develop and enact.

A North Korean drone entered the northern end of a 3.7km (2.2 miles) radius no-fly zone around South Korea's presidential office in Seoul when it intruded into the country's airspace last month, South Korean military officials say. "It [the drone] briefly flew into the northern edge of the zone, but it did not come close to key security facilities," a military official told South Korea's Yonhap News Agency on Thursday. The drone was among five North Korean unmanned aerial vehicles that crossed the border and entered South Korean airspace on December 26, prompting South Korea's military to scramble fighter jets and attack helicopters. The military could not bring down the drones, which flew over South Korean territory for hours. South Korea's Joint Chiefs of Staff had denied that one of the drones intruded into the presidential office no-fly zone, however, on Thursday confirmed that a drone had violated the northern end of the secure area but did not fly directly over the Yongsan area, where the office of President Yoon Suk-yeol is located.
