eric - ej223513 - the development of directional preference in writing movements., visible language, 1979
the developing directional preferences in writing and drawing that were observed in subjects between four years of age and adulthood suggest that two semiindependent motor systems are involved in writing: one for rapid and nonfigurative tasks, the other--which occurs later--for precision and symbolic functions.

arithmetic control of llms for diverse user preferences: directional preference alignment with multi-objective rewards
fine-grained control over large language models (llms) remains a significant challenge, hindering their adaptability to diverse user needs. while reinforcement learning from human feedback (rlhf) shows promise in aligning llms, its reliance on scalar rewards often limits its ability to capture diverse user preferences in real-world applications. to address this limitation, we introduce the directional preference alignment (dpa) framework. unlike the scalar-reward rlhf, dpa incorporates multi-objective reward modeling to represent diverse preference profiles. additionally, dpa models user preferences as directions (i.e., unit vectors) in the reward space to achieve user-dependent preference control. our method involves training a multi-objective reward model and then fine-tuning the llm with a preference-conditioned variant of rejection sampling finetuning (rsf), an rlhf method adopted by llama 2. this method enjoys a better performance trade-off across various reward objectives. in comparison with the scalar-reward rlhf, dpa offers users intuitive control over llm generation: they can arithmetically specify their desired trade-offs (e.g., more helpfulness with less verbosity). we also validate the effectiveness of dpa with real-world alignment experiments on mistral-7b. our method provides straightforward arithmetic control over the trade-off between helpfulness and verbosity while maintaining competitive performance with strong baselines such as direct preference optimization (dpo).

personalized steering of large language models: versatile steering vectors through bi-directional preference optimization
researchers have been studying approaches to steer the behavior of large language models (llms) and build personalized llms tailored for various applications. while fine-tuning seems to be a direct solution, it requires substantial computational resources and may significantly affect the utility of the original llm. recent endeavors have introduced more lightweight strategies, focusing on extracting "steering vectors" to guide the model's output toward desired behaviors by adjusting activations within specific layers of the llm's transformer architecture. however, such steering vectors are directly extracted from the activations of human preference data and thus often lead to suboptimal results and occasional failures, especially in alignment-related scenarios. this work proposes an innovative approach that could produce more effective steering vectors through bi-directional preference optimization. our method is designed to allow steering vectors to directly influence the generation probability of contrastive human preference data pairs, thereby offering a more precise representation of the target behavior. by carefully adjusting the direction and magnitude of the steering vector, we enabled personalized control over the desired behavior across a spectrum of intensities. extensive experimentation across various open-ended generation tasks, particularly focusing on steering ai personas, has validated the efficacy of our approach. moreover, we comprehensively investigate critical alignment-concerning scenarios, such as managing truthfulness, mitigating hallucination, and addressing jailbreaking attacks. remarkably, our method can still demonstrate outstanding steering effectiveness across these scenarios. furthermore, we showcase the transferability of our steering vectors across different models/loras and highlight the synergistic benefits of applying multiple vectors simultaneously.

mechanical low back pain
low back pain is usually nonspecific or mechanical. mechanical low back pain arises intrinsically from the spine, intervertebral disks, or surrounding soft tissues. clinical clues, or red flags, may help identify cases of nonmechanical low back pain and prompt further evaluation or imaging. red flags include progressive motor or sensory loss, new urinary retention or overflow incontinence, history of cancer, recent invasive spinal procedure, and significant trauma relative to age. imaging on initial presentation should be reserved for when there is suspicion for cauda equina syndrome, malignancy, fracture, or infection. plain radiography of the lumbar spine is appropriate to assess for fracture and bony abnormality, whereas magnetic resonance imaging is better for identifying the source of neurologic or soft tissue abnormalities. there are multiple treatment modalities for mechanical low back pain, but strong evidence of benefit is often lacking. moderate evidence supports the use of nonsteroidal anti-inflammatory drugs, opioids, and topiramate in the short-term treatment of mechanical low back pain. there is little or no evidence of benefit for acetaminophen, antidepressants (except duloxetine), skeletal muscle relaxants, lidocaine patches, and transcutaneous electrical nerve stimulation in the treatment of chronic low back pain. there is strong evidence for short-term effectiveness and moderate-quality evidence for long-term effectiveness of yoga in the treatment of chronic low back pain. various spinal manipulative techniques (osteopathic manipulative treatment, spinal manipulative therapy) have shown mixed benefits in the acute and chronic setting. physical therapy modalities such as the mckenzie method may decrease the recurrence of low back pain and health care expenditures. physical therapy modalities such as the mckenzie method may decrease the recurrence of low back pain and use of health care. educating patients on prognosis and incorporating psychosocial components of care such as identifying comorbid psychological problems and barriers to treatment are essential components of long-term management.

the influence of centralization and directional preference on spinal control in patients with nonspecific neck pain
the prevalence of neck pain is estimated at 20-70% and represents the second leading musculoskeletal cause of disability in the united states. mechanical diagnosis and therapy (mdt) is a system of musculoskeletal examination and treatment which involves an analysis of the patient’s response to end range repeated movements. the testing of end range repeated movements may determine a direction of motion that improves the person’s symptoms and/or movement and is referred to as a directional preference (dp). the deep neck flexor test (dnft) assesses neuromuscular control of the cervical spine, which is often impaired in people with neck pain. a published case study of a person with neck pain found a relationship between directional preference and improved deep neck flexor strength. the purpose of this study is to determine the correlation between dp and neuromuscular control, as measured with the dnft, in patients referred for physical therapy at the catholic health system of buffalo, ny.
