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.
directional preference sample progressions for low back pain with radiating pain – adult and pediatric printable resources for speech and occupational therapists
this resource is for clients wanting to take control of back pain that is radiating down the leg. directional preference exercise, or stretching in a direction that reduces or brings symptoms closer to your back, can be useful to help control symptoms early on during the rehabilitation process. this intervention outlines some strategies that can help move the pain out of the leg during recovery.

association between directional preference and centralization in patients with low back pain
2 common examination findings that have been studied as criteria for classifying patients with low back pain, according to the patient response method, are ➡️directional preference (dp) and ➡️centralization (cen). dp has been defined as either 1️⃣ a specific direction of trunk movement or posture no

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.

directional preference in avian midbrain saliency computing nucleus reflects a well-designed receptive field structure
neurons responding sensitively to motions in several rather than all directions have been identified in many sensory systems. although this directional preference has been demonstrated by previous studies to exist in the isthmi pars magnocellularis (imc) of pigeon (columba livia), which plays a key role in the midbrain saliency computing network, the dynamic response characteristics and the physiological basis underlying this phenomenon are unclear. herein, dots moving in 16 directions and a biologically plausible computational model were used. we found that pigeon imc’s significant responses for objects moving in preferred directions benefit the long response duration and high instantaneous firing rate. furthermore, the receptive field structures predicted by a computational model, which captures the actual directional tuning curves, agree with the real data collected from population imc units. these results suggested that directional preference in imc may be internally prebuilt by elongating the vertical axis of the receptive field, making predators attack from the dorsal-ventral direction and conspecifics flying away in the ventral-dorsal direction, more salient for avians, which is of great ecological and physiological significance for survival.
