Policy gradient methods[1] have two components to them - the probability and the reward . The goal is to maximize the reward and increasing the probability of the action that leads to it, from the state. Different algorithms have tweaked the reward weight in the objective to try and reduce its variance. For eg: REINFORCE subtracts a baseline (moving average reward) from the reward. PPO uses advantage which subtracts a value function from the reward. GRPO also uses advantage by approximating the value function with Monte Carlo groups.
Most problems that use Reinforcement Learning design rewards such that a good result receives a positive reward while a bad result leads to a negative reward. This doesn't seem to be an issue until we realize that the rewards or advantages could cancel each other out completely or reduce the effective signal the policy (model) receives, since optimization happens at the level of batches[2]. A better way to retain and weigh the signal (inspired by the cross-entropy loss[3] formulation) is to have them all belong to one range - negative. Gradient descent (or its variant which optimizes the policy) can go on to minimize the negative of the policy gradient objective (or ascent maximize it) with the goal of reaching , since that's the max weight possible. A obtained in this setup means the policy converged whereas with the bi-range rewards it would mean void.
To test the hypothesis, we utilize the below:
Note: Even though the reward for this trial is in range , the baseline advantages (which is the weight in the GRPO algorithm) could be positive or negative, post standardization. Below are sample advantages of a single group:
rewards

dtype=torch.float64)

-0.9704, -1.8990], dtype=torch.float64)
# Experiment
reward_min = -275.0 # A completion could have 0 tokens or 1024 (max length)
reward_max = 0
((rewards - reward_min) / (reward_max - reward_min)) - 1
tensor([-0.2545, -0.1636, -0.2764, -0.6545, -0.0909, -0.4873, -0.2036, -0.1200,
-0.6509, -0.9091], dtype=torch.float64)
| Metric | Graph | Comment |
| eval/reward | The max reward possible is 0. | |
| eval/advantages | The advantage of baseline (3 epochs) only, to zoom into the area in the left plot. The advantages flip and are tiny. | |
| eval/entropy | ||
| eval/frac_reward_zero_std | This measures how many groups have rewards with standard deviation zero. | |
| eval/completions/mean_length | ||
| eval/completions/min_length | ||
| eval/completions/max_length | ||
| eval/loss | ||
| train/grad_norm[4] |
From the above, while it may look like the baseline also maximized the reward, the sample completions tell a different story - the completions become gibberish with the bi-range rewards both with shorter and longer training, while in the experiment, they remain coherent. And so a better way to compare the results is to look at the entropy which is stabler in the Experiment version.

| In what specific ways do learning disabilities impact an individual's ability to develop and maintain social skills and social functioning, and how can interventions and support systems mitigate these effects? Provide both qualitative and quantitative examples in your explanation. | Learning disabilities, often characterized by difficulty in learning new words, understanding concepts, and performing cognitive tasks, can have a significant impact on an individual's ability to develop and maintain social skills and social functioning. While these disorders have traditionally been treated as medical conditions, much research has shown that they often contribute to a range of social and psychological difficulties. Additionally, there is evidence to suggest that early intervention and support systems can enable individuals with learning disabilities to improve their social skills and enhance their social functioning. Qualitative Examples: 1. Independent Book Analysis: A small study conducted by Lilliam et al. (2013) in children with an Attention Deficit Hyperactivity Disorder (ADHD) compared the effect of an independent book analysis on performance in the classroom compared to the effect of a regular teacher in an academic setting. While the independent book analysis showed significant improvements in reading and math skills compared to the peer-teach situation, the authors caution in recommending that this approach be used with children who are resistant or have a history of social skills deficits in classrooms. 2. Avon Longitudinal Study of Adolescent Health: The Avon Longitudinal Study (ALSS) is a longitudinal study that has examined the impact of smoking, alcohol, and other behaviors on adolescent health. Although smoking significantly decreases the rate of smoking behavior and the prevalence of chronic conditions in teenage adolescents, some laboratories prove that smoking may have detrimental effects on child development, including emotional development, social skills, and learning difficulties. Quantitative Examples: 1. An Analysis of Children Who Experience Learning Disability and Social Outcomes: Often, this analysis found that children with learning disabilities exhibit significantly higher rates of anxiety, depression, social ambivalence, and social isolation compared to those with no learning disability. These findings demonstrate how learning disabilities negatively impact social ability, leading to lower productivity and life skills. 2. Participation in Adaptive Trainers: Adaptive training involves successful implementation of adaptive strategies to overcome learning disabilities, such as the reading strategy for children with reading deficits (Segall et al., 2007). Applying adaptive strategies can help individuals with learning disabilities develop new capabilities, adapt to new environments, and flourish in society. To mitigate these effects, interventions and support systems can provide specific goals, self-help skills, and group norms. For example, medication management can be given to individuals with attention deficit hyperactivity disorder, supports are provided in the classroom to aid in social skills, and community-based support groups can provide citizens with life skills and resources. Additionally, awareness and joint participation in educational policies and support can improve the mitigation of learning disabilities. In conclusion, learning disabilities impact individuals' social and educational skills and can contribute to social isolation, anxiety, and depression. Mentioning knowledge, education, accessibility of early intervention measures, and realistic expectations must be addressed for effective coping with learning disabilities. With the right support systems, individuals with learning disabilities can develop new abilities and avenues for their education, form strong relationships, and contribute positively to society. | 601/-10.2 | A comprehensive understanding of learning disabilities (LD) and its impact on societal relationships is essential. This multifaceted assessment involves identifying broader societal implications and therapeutic avenues. The interactions reflect the complexity of these conditions across different domains. 1.

Remember! | 507/-0.05 | 501/-0.001 | Learning disabilities refer to a broad range of personality traits or tractable impairments that prevent individuals from effectively participating in society, including social interaction, learning, and communication. These traits can have catastrophic consequences, affecting an individual's ability to perceive and participate in the world around them. By addressing these challenges through culturally sensitive interventions and support systems, it becomes increasingly essential to consider how they impact social skills and social functioning. 1. **Qualitative Perspectives**: Measuring Social Individual Differences (SID) systematically suggests that these impairments are primarily associated with imbalance of different aspects of social functioning. This statistical approach can offer a description of how diverse learning disabilities materialize, including those that appear predominantly in certain subgroups of society. This analysis can provide information as to why a minority might experience challenges, which can lead to faster learning and more creative solutions within their respective groups. 2. **Educational Supports**: Diverse and inclusive educational environments where individuals with learning disabilities are given a natural pathway for their participation and educational gains are key. Educational development that accounts for diverse learning styles helps demystify the process and encourages them to feel more appreciated for their differences. 3. **Access to Professional Resources**: Access to identification, assessment, and treatment services for those with learning disabilities in diverse communities is crucial. These programs can provide early intervention, counseling, and referrals depending on the specific needs and potential severity of the disability. 4. **Support Systems**: Structured programs and services that offer support, such as workshops, school forums, or workshops for parents, can serve as a beacon of care and understanding. These resources can help individuals adapt and confidently participate in society. 5. **Use of Technologies**: Technologies like adaptive devices or software to enhance learning for individuals with distinct physical capabilities can play a role in performance. However, these technologies must be designed to be accessible and catered to these impairments, ensuring that they are not hindered by their physical limitations. 6. **Assessment and Evaluation**: Continuous monitoring and evaluation of an individual's progress is instrumental in tailoring interventions to specific needs. Inclusion and accessibility within healthcare systems and professional settings are paramount to ensuring that learning disabilities are properly evaluated and addressed. In essence, addressing learning disabilities is not just about identifying and treating the disorder, but also about addressing the institutions and environments that support and enable these individuals to thrive and participate in society. This synergy between accommodations, awareness, and advanced strategies holds the potential to enhance the quality of life for individuals with these traits without compromising on the ability to engage effectively in their broader roles. | When it comes to mental health and development, effective strategies for addressing learning disabilities often reflect a holistic approach that considers the impact on broader social and emotional functioning. This involves a diverse range of interventions that cater to the unique needs of the individual based on their severity and individual context. Here are a few strategies that can be employed: 1. **Challenging Attitudes Training**: While a cultural shift towards diversity is crucial, there is no one-size-fits-all approach. Training programs that focus on recognizing and changing negative attitudes specific to learning disabilities often provide strategies for empathy, cognitive rehabilitation, and social skills improvement. These approaches don't only help individuals but also promote a culture of support where each student feels valued and included. 2. **Assessment and Research**: Vocational and educational services are crucial in identifying the needs of individuals. This way, professionals can assess the specific areas of need and tailor interventions. This integration into broader educational programming can lead to more tailored interventions and improve the outcomes for students. 3. **Provider-Centered Therapy**: This approach involves therapists working closely with families, which is not always limited to educational settings but includes access to comprehensive support including counseling and therapy. This ensures that students' needs are met from multiple perspectives. 4. **Behavioral Support Systems**: For children, there are numerous programs that incorporate therapies and supports specifically for learning disabilities. These programs target cognitive behavior therapies that help individuals adapt to traumatic experiences within the context of innate cognitive abilities. 5. **Engagement in Social Skills Training**: Depending on the severity and type of learning disability, there may be tailored activities or environments that focus on enhanced social engagement. This could be through mentorship, study groups, or specialized workshops within schools. 6. **Continuous Assessment**: Striving for continuous improvement can be essential in lifelong learning. This means monitoring progress and adjusting interventions as needed to accommodate new challenges. 7. **Client-Personalized Therapy**: In some cases, personal and life circumstances might be necessary to tailor interventions to personalized outcomes. 8. **Educational and Clinical Partnerships**: Partnerships between schools, universities, and community organizations can facilitate learning disabilities into a broader educational continuum. This approach acknowledges the multifaceted nature of mental health conditions and devotes resources to support the students not just in their academic pursuits, but also with long-term social and emotional well-being. By blending these strategies, you can ensure that the long-term development of learning disabilities is effectively addressed and its impact on social and personal outcomes is minimised. | 512/-0.144 | 504/-0.016 |
There are possibly other ways to design the reward/advantage (depending on what is in the final objective) so they don't clash. The above experiment proposes a way (modified min-max normalization for GRPO) which as hypothesized provides stabler and truer learning with the clearer signal.
A class of reinforcement learning algorithms which directly maximize the expected return by differentiating a parameterized policy, which in large language models corresponds to directly optimizing the probability distribution over generated tokens.
If the policy starts out with all negative rewards, there won't be a cancellation issue during this time. But when the policy does better to get both types of rewards (most policies would begin this way), the issue can mess with the learning.
Log loss or cross-entropy loss takes in a probability (which is always in the range ) and maps it to .
