Optimizing Test-Time Compute for LLMs: A Meta-Reinforcement Learning Approach with Cumulative Regret Minimization

0

Enhancing the reasoning abilities of LLMs by optimizing test-time compute is a critical research challenge. Current approaches primarily rely on fine-tuning models with search traces or RL using binary outcome rewards. However, these methods may not fully exploit test-time compute efficiently. Recent research suggests that increasing test-time computing can improve reasoning by generating longer solution traces and incorporating structured steps such as reflection, planning, and algorithmic search. Key challenges remain whether LLMs allocate computational resources effectively based on task complexity and discover solutions to more difficult problems when given a larger test-time compute budget. Addressing these is crucial for improving efficiency and generalization in LLM reasoning.

Recent advancements in scaling test-time compute have explored training separate verifiers for selection-based methods like best-of-N or beam search, which can sometimes be more effective than increasing data or model size. However, fine-tuning on unfamiliar search traces may lead to memorization rather than genuine reasoning improvements. RL-based approaches have demonstrated promise in generating chain-of-thought reasoning, enabling models to introspect, plan, and refine their outputs. However, increasing reasoning length does not always correlate with higher accuracy, as models may generate unnecessarily long sequences without meaningful progress. To address this, recent efforts have incorporated structured reward mechanisms and length penalties to encourage efficient reasoning, ensuring that models focus on producing informative, concise solutions rather than excessive computation.

Researchers from Carnegie Mellon University & Hugging Face investigate optimizing test-time compute for LLMs by refining how models allocate computational resources during reasoning. Instead of relying solely on outcome-reward RL, they introduce a fine-tuning approach that balances exploration and exploitation, ensuring steady progress toward correct answers. Their method incorporates a dense reward bonus to quantify progress, improving efficiency. Evaluations on mathematical benchmarks demonstrate that this approach significantly outperforms existing methods, enhancing both accuracy and token efficiency. Their findings also suggest that optimizing for progress minimizes computational regret while improving solution discovery without sacrificing accuracy.

The problem of optimizing test-time compute is framed as a meta reinforcement learning (meta RL) challenge. The goal is to maximize an LLM’s performance within a given test-time token budget by balancing exploration and exploitation. Instead of solely optimizing for outcomes, the proposed Meta Reinforcement Fine-Tuning (MRT) approach minimizes cumulative regret by rewarding progress across sequential episodes. This budget-agnostic strategy allows LLMs to make steady progress regardless of training constraints. By incorporating a reward bonus based on incremental improvements, MRT ensures efficient test-time compute usage, enhancing adaptability and response accuracy within deployment constraints.

The study evaluates the effectiveness of MRT in optimizing test-time computation, with a focus on achieving high accuracy while maintaining computational efficiency. The study presents key findings, compares MRT’s efficiency with prior methods, and conducts ablation experiments on token budget and progress. MRT consistently outperforms baseline models and outcome-reward RL (GRPO), achieving state-of-the-art results in its size category. It also improves out-of-distribution robustness and delivers larger performance gains with weaker models. Furthermore, MRT significantly enhances token efficiency, requiring fewer tokens for comparable accuracy. Additional experiments highlight its effectiveness in backtracking search and linearized evaluations.

In conclusion, the study reframes optimizing test-time compute as a meta-reinforcement learning (RL) problem, introducing cumulative regret as a key metric. State-of-the-art outcome-reward RL models fail to minimize regret, often struggling with novel queries within a token budget. This limitation arises from training solely with outcome rewards, which lack the granularity to guide stepwise progress. To address this, MRT is proposed, incorporating a dense reward bonus that encourages incremental improvement. MRT enhances test-time compute efficiency, achieving 2-3x better performance and 1.5x greater token efficiency in mathematical reasoning compared to outcome-reward RL, though several open questions remain.

The Role of Machine Learning in Portfolio Optimization

Introduction:

The world of finance has long been dominated by traditional investment strategies, often based on rigid algorithms and manual data analysis. However, the advent of machine learning (ML) has revolutionized the industry, especially in portfolio optimization. By combining vast amounts of data with advanced algorithms, machine learning offers the ability to make smarter, faster, and more accurate investment decisions. In this article, I will explore how machine learning in portfolio optimization is reshaping the landscape of investment management, its benefits, challenges, and real-world applications.

Understanding Portfolio Optimization

Before diving into the role of machine learning, it’s essential to understand what portfolio optimization is. At its core, portfolio optimization aims to find the ideal balance between risk and return for an investment portfolio. The goal is to maximize returns while minimizing risk, often using mathematical models to achieve this balance.

Traditional Portfolio Optimization

Traditionally, portfolio optimization has relied on models such as Modern Portfolio Theory (MPT), which emphasizes diversification to reduce risk. The efficient frontier, a concept introduced by Harry Markowitz, helps investors balance risk and return by optimizing the allocation of assets. While these models have been instrumental in portfolio management, they often fall short in the face of complex market conditions and rapidly changing financial environments.

The Need for Machine Learning

The limitation of traditional models is that they rely on static assumptions and human intervention. Machine learning offers a solution by enabling real-time data processing and adaptive decision-making. It can continuously learn from new market data and adjust investment strategies accordingly.

The Basics of Machine Learning

To fully appreciate how machine learning enhances portfolio optimization, we must first understand what machine learning is and how it works.

What is Machine Learning?

Machine learning is a subset of artificial intelligence (AI) that focuses on building systems that can learn from data, improve over time, and make predictions without being explicitly programmed. It involves the use of algorithms to analyze large sets of data, identify patterns, and make decisions based on that analysis.

Types of Machine Learning

There are three primary types of machine learning:

  • Supervised Learning: The model is trained using labeled data and learns to predict outcomes based on that data.
  • Unsupervised Learning: The model identifies hidden patterns in data without any prior labels.
  • Reinforcement Learning: The model learns by interacting with the environment and receiving feedback based on its actions.

Why Machine Learning is Crucial in Finance

In finance, machine learning allows for more accurate forecasting, more effective risk management, and a better understanding of market trends. The ability to process massive amounts of data in real time gives investors a competitive edge and helps optimize portfolios with precision.

Applications of Machine Learning in Portfolio Optimization

Machine learning is already making waves in portfolio optimization, bringing a wealth of benefits to asset managers and investors alike. Here’s how ML is applied:

Risk Assessment and Management: One of the most powerful applications of machine learning is in risk management. Traditional risk models are often based on historical data and static assumptions. In contrast, machine learning can process vast amounts of real-time data and predict potential risks with much greater accuracy. This enables portfolio managers to anticipate market shifts and make adjustments before risks materialize.

For example, ML algorithms can analyze patterns in financial markets to forecast volatility and adjust a portfolio’s exposure to different asset classes accordingly.

Asset Allocation: Machine learning is used to enhance asset allocation strategies. By analyzing historical data, economic indicators, and real-time market information, ML models can recommend optimal allocations for different asset types—equities, bonds, commodities, and more.

The algorithms continuously adapt to changing market conditions, ensuring that the portfolio stays aligned with the investor’s risk tolerance and objectives.

Predictive Analytics for Returns: Machine learning is also used to predict stock returns and market trends. By analyzing historical stock prices, economic data, and financial indicators, ML algorithms can identify patterns and correlations that traditional models may overlook. This predictive capability allows for more informed decision-making when selecting assets for a portfolio.

Moreover, NLP in financial news allows machine learning algorithms to analyze unstructured data, such as news articles, earnings reports, and market sentiment, further improving the accuracy of predictions.

Rebalancing Portfolios: Portfolio rebalancing involves adjusting the composition of assets to maintain a desired level of risk and return. ML algorithms help automate this process by continuously monitoring market conditions and portfolio performance, making rebalancing decisions in real time based on pre-defined rules or goals.

Portfolio Customization: Machine learning also enables customized portfolios tailored to individual investors. By analyzing an investor’s preferences, risk tolerance, and financial goals, ML models can create portfolios that are aligned with their unique requirements.

Benefits of Machine Learning in Portfolio Optimization

Machine learning’s impact on portfolio optimization is profound, offering several benefits that enhance both performance and efficiency:

Improved Decision-Making: Machine learning can process large datasets quickly and identify patterns that would take a human analyst years to uncover. This leads to more informed and accurate investment decisions.

Handling Large Datasets: Financial markets generate massive amounts of data every second. Machine learning can efficiently process and analyze this data, making it possible for portfolio managers to make decisions based on real-time information rather than relying on outdated data.

Real-Time Analysis: ML models can provide real-time analysis, which is crucial for staying ahead of market fluctuations. This enables investors to respond to changes quickly and adjust their portfolios accordingly.

Better Risk-Return Tradeoff: Machine learning’s ability to dynamically adjust portfolio allocations based on changing conditions ensures a better risk-return tradeoff. This can result in portfolios that achieve higher returns without taking on excessive risk.

Challenges and Limitations of Machine Learning in Portfolio Optimization

Despite its many benefits, machine learning in portfolio optimization is not without its challenges:

Data Quality and Availability: Machine learning algorithms rely heavily on high-quality data. The availability of clean, relevant data is essential for the accuracy of predictions. Inaccurate or incomplete data can lead to poor decision-making and losses.

Overfitting and Model Accuracy: One of the risks of machine learning models is overfitting, where a model is too closely aligned with historical data, making it less effective in predicting future trends. This is a critical issue in portfolio optimization, as market conditions can change rapidly.

Complexity of Algorithms: The complexity of machine learning models requires specialized knowledge to implement and interpret. While the technology has made significant advances, the need for skilled professionals to manage these models is still high.

Market Uncertainty: Machine learning models are built on historical data, and while they are excellent at predicting patterns based on the past, they may struggle to adapt to sudden, unforeseen market changes or crises.

Real-World Examples of Machine Learning in Portfolio Optimization

Machine learning has already found practical applications in the investment world:

Hedge Funds and Institutional Investors: Many hedge funds and institutional investors have adopted machine learning models to optimize their portfolios. For example, firms like Two Sigma and Renaissance Technologies use ML algorithms to manage billions of dollars in assets.

Retail Investors and Robo-Advisors: Retail investors benefit from robo-advisors powered by machine learning. These platforms, such as Betterment and Wealthfront, use algorithms to create and manage personalized portfolios with little human intervention.

Innovative ML Models: Several innovative ML models are being used for portfolio optimization, such as reinforcement learning algorithms that continuously adapt and learn from new data.

The Future of Machine Learning in Portfolio Optimization

The future of machine learning in portfolio optimization is bright. We can expect advancements in AI technologies, including better predictive models, integration with big data, and real-time adaptation to changing market conditions. Successful AI investment strategies will become more precise, making it possible for investors to achieve their financial goals with greater efficiency.

A Code Implementation to Build an AI-Powered PDF Interaction System in Google Colab Using Gemini Flash 1.5, PyMuPDF, and Google Generative AI API

0

In this tutorial, we demonstrate how to build an AI-powered PDF interaction system in Google Colab using Gemini Flash 1.5, PyMuPDF, and the Google Generative AI API. By leveraging these tools, we can seamlessly upload a PDF, extract its text, and interactively ask questions, receiving intelligent responses from Google’s latest Gemini Flash 1.5 model.

!pip install -q -U google-generativeai PyMuPDF python-dotenv

First we install the necessary dependencies for building an AI-powered PDF Q&A system in Google Colab. google-generativeai provides access to Gemini Flash 1.5, enabling natural language interactions, while PyMuPDF (also known as Fitz) allows efficient text extraction from PDFs. Also, python-dotenv helps manage environment variables, such as API keys, securely within the notebook.

from google.colab import files
uploaded = files.upload()

We upload files from your local device to Google Colab. When executed, it opens a file selection dialog, allowing you to choose a file (e.g., a PDF) to upload. The uploaded file is stored in a dictionary-like object (uploaded), where keys represent file names and values contain the file’s binary data. This step is essential for directly processing documents, datasets, or model weights in a Colab environment.

import fitz


def extract_pdf_text(pdf_path):
    doc = fitz.open(pdf_path)
    full_text = ""
    for page in doc:
        full_text += page.get_text()
    return full_text


pdf_file_path="/content/Paper.pdf"
document_text = extract_pdf_text(pdf_path=pdf_file_path)
print("Document text extracted!")
print(document_text[:1000]) 

We use PyMuPDF (fitz) to extract text from a PDF file in Google Colab. The function extract_pdf_text(pdf_path) reads the PDF, iterates through its pages, and retrieves the text content. The extracted text is then stored in document_text, with the first 1000 characters printed to preview the content. This step is crucial for enabling text-based analysis and AI-driven question answering from PDFs.

import os
os.environ["GOOGLE_API_KEY"] = 'Use your own API key here'

We set the Google API key as an environment variable in Google Colab. The API key is required to authenticate requests to Google Generative AI, allowing access to Gemini Flash 1.5 for AI-powered text processing. Replacing ‘Use your own API key here’ with a valid key ensures that the model can generate responses securely within the notebook.

import google.generativeai as genai


genai.configure(api_key=os.environ["GOOGLE_API_KEY"])


model_name = "models/gemini-1.5-flash-001"


def query_gemini_flash(question, context):
    model = genai.GenerativeModel(model_name=model_name)
    prompt = f"""
Context: {context[:20000]}


Question: {question}


Answer:
"""
    response = model.generate_content(prompt)
    return response.text


pdf_text = extract_pdf_text("/content/Paper.pdf")


question = "Summarize the key findings of this document."
answer = query_gemini_flash(question, pdf_text)
print("Gemini Flash Answer:")
print(answer)

Finally, we configure and query Gemini Flash 1.5 using a PDF document for AI-powered text generation. It initializes the genai library with the API key and loads the Gemini Flash 1.5 model (gemini-1.5-flash-001). The query_gemini_flash() function takes a question and extracted PDF text as input, formulates a structured prompt, and retrieves an AI-generated response. This setup enables automated document summarization and intelligent Q&A from PDFs.

In conclusion, following this tutorial, we have successfully built an interactive PDF-based interaction system in Google Colab using Gemini Flash 1.5, PyMuPDF, and the Google Generative AI API. This solution enables users to extract information from PDFs and interactively query them easily. The combination of Google’s cutting-edge AI models and Colab’s cloud-based environment provides a powerful and accessible way to process large documents without requiring heavy computational resources.

SYMBOLIC-MOE: Mixture-of-Experts MoE Framework for Adaptive Instance-Level Mixing of Pre-Trained LLM Experts

0

Like humans, large language models (LLMs) often have differing skills and strengths derived from differences in their architectures and training regimens. However, they struggle to combine specialized expertise across different domains, limiting their problem-solving capabilities compared to humans. Specialized models like MetaMath, WizardMath, and QwenMath excel at mathematical reasoning but often underperform on tasks requiring common sense or medical knowledge. Even within specific domains such as mathematics, models show nuanced variations in capability, e.g., one might excel at algebra while another masters geometry. creates a need for frameworks that can identify and select the most appropriate expert models for specific problems.

Existing approaches like Mixture-of-Experts (MoE) models distribute computation across multiple specialized components, with recent emphasis on sparse approaches that activate only the most relevant experts per input. The Sparse MoE (SMoE) method has improved efficiency across vision, language, and multimodal tasks but requires combining models in the parameter space through joint training. More recent frameworks like MoA (Mixture-of-Agents) attempt to address this by combining LLM outputs symbolically. Further, Multi-agent reasoning approaches have emerged as alternatives, such as the Student-teacher technique that distills reasoning capabilities from stronger to weaker agents, while debate frameworks allow multiple agents to refine arguments collectively.

Researchers from UNC Chapel Hill have proposed SYMBOLIC-MOE, a symbolic, text-based, and gradient-free Mixture-of-Experts framework to enable adaptive instance-level mixing of pre-trained LLM experts. It takes a fine-grained perspective by emphasizing specialized skills within broader domains like algebra within mathematics or molecular biology within biomedical reasoning. They also introduced a skill-based recruiting strategy that dynamically selects the most relevant expert LLMs for each specific reasoning task based on their demonstrated strengths. Moreover,  SYMBOLIC-MOE outperforms strong LLMs like GPT4o-mini, as well as multiagent approaches, with an absolute average improvement of 8.15% over the best multi-agent baseline.

SYMBOLIC-MOE consists of three stages: model profile creation and aggregator selection followed by expert recruitment and final answer generation, both of which take place during inference. To maximize throughput and efficiency, SYMBOLIC-MOE introduces an innovative batching strategy where all instances are first analyzed to determine which LLMs will be needed. The system then intelligently groups problem instances based on their required experts, allowing each active expert model to receive all relevant instances in a single batch and ensuring each expert is loaded only once. This solution enables efficient batched inference on a single GPU while supporting a diverse pool of 16 LLMs, with the flexibility to add more GPUs for further parallelization.

SYMBOLIC-MOE shows exceptional performance across diverse benchmarks. It consistently outperforms all baseline approaches, surpassing single-model strategies, multi-agent debates with a single model, and multi-model multi-agent frameworks like MoA and ReConcile. It exceeds the strongest multi-agent baseline (Self-MoA) by an impressive 8.15% absolute average improvement, 8.28% on MMLU-Pro, 13.45% on AIME, 4.92% on GPQA, and 6.08% on MedMCQA. SYMBOLIC-MOE achieves comparable or superior performance to larger models with 70B parameters by using four 7-8B parameter models. It outperforms Llama3.3 70B on AIME and GPQA while matching its performance on MedMCQA. Efficiency testing reveals that it operates 44% faster on a single GPU than MoA while achieving better accuracy.

In conclusion, researchers introduced SYMBOLIC-MOE, a scalable MoE framework that combines models through their symbolic output. This method identifies the skills needed for a given problem and recruits agents based on those skills to engage in a discussion about a given input. SYMBOLIC-MOE outperforms standard inference-time scaling methods as well as other debate frameworks and other mixture-of-agents methods, leading to strong performance across domains without human intervention. It’s average performance across heterogeneous tasks is in fact stronger than that of advanced proprietary models such as GPT4o-mini. However, this method has limitations: (a) It involves running multiple models, which increases inference cost, and (b) it relies on skills inferred from a small validation set to set the agent profiles.
