Reinforcement Learning, despite its popularity in a variety of fields, faces some fundamental difficulties that refrain users from exploiting its full potential. To begin with, algorithms like PPO, which are widely used, suffer from the curse of sample inefficiency (the need for multiple episodes to learn basic actions). Moving on, Off-Policy methods like SAC and DrQ offer some immunity against the above problem. They are applicable in the real world while being compute-efficient, but they have drawbacks. Off-policy methods often require dense reward signals, which means their performance is undermined in rewards' sparsity or local optima. This suboptimality can be
Static analysis is an inherent part of the software development process since it enables such activities as bug finding, program optimization, and debugging. The traditional approaches have two major drawbacks: methods based on code compilation are bound to fail in any development scenario where the code is incomplete or rapidly changing, and the need for tailoring calls for intimate knowledge of compiler internals and IRs inaccessible to many developers. These issues prevent static analysis tools from being widely used in real-world scenarios. The existing static analysis tools, such as FlowDroid and Infer, use IRs to detect issues in programs. However,
Viruses infect organisms across all domains of life, playing key roles in ecological processes such as ocean biogeochemical cycles and the regulation of microbial populations while also causing diseases in humans, animals, and plants. Viruses are Earth's most abundant biological entities, characterized by rapid evolution, high mutation rates, and frequent genetic exchanges with hosts and other viruses. This constant genetic flux leads to highly diverse genomes with mosaic architectures, challenging functional annotation, evolutionary analysis, and taxonomic classification. Viruses have likely emerged multiple times throughout history despite their diversity, with some lineages predating the last universal common ancestor (LUCA). This highlights
The Large Language Models (LLMs) are highly promising in Artificial Intelligence. However, despite training on large datasets covering various languages and topics, the ability to understand and generate text is sometimes overstated. LLM applications across multiple domains have proven to have little impact on improving human-computer interactions or creating innovative solutions. This is because the deep layers of the LLMS don't contribute much and, if removed, don't affect their performance. This underutilization of deep layers shows inefficiency within the models. Current methods showed that deeper layers of LLMs contributed little to their performance. Although used to stabilize training, techniques like
