well that seems to have worked well

It amazes me that the most important metrics (lines of code, story points, cycle time, devex satisfaction) in development are the two that are never discussed, let alone measured ... mean time to answer (mttA) and mean time to question (mttQ).

Local models now protect your privacy while still accessing powerful LLM capabilities

Chain small and large LLMs to get best performance while keeping data private

🔍 Original Problem:

Users share sensitive personal information with proprietary LLMs during inference, raising privacy concerns. While local open-source models help with privacy, they perform worse than proprietary models.

-----

🛠️ Solution in this Paper:

• PAPILLON: A multi-stage pipeline where local models act as privacy-conscious proxies
• Uses DSPy prompt optimization to find optimal prompts for privacy preservation
• Two key components:
- Prompt Creator: Generates privacy-preserving prompts
- Information Aggregator: Combines responses while protecting PII
• Created PUPA benchmark with 901 real-world user-LLM interactions containing PII

-----

💡 Key Insights:

• Simple redaction significantly lowers LLM response quality
• Privacy-conscious delegation can balance privacy and performance
• Smaller local models can effectively leverage larger models while protecting privacy
• Prompt optimization improves both quality and privacy metrics

-----

📊 Results:

• Maintains 85.5% response quality compared to proprietary models
• Restricts privacy leakage to only 7.5%
• Outperforms simple redaction approaches
• Shows consistent improvement across different model sizes

Huge efforts to improve LLMs for tool use, computer use, reasoning, and long-context understanding.

Here are a few interesting papers for the weekend:

1). Agentic Information Retrieval
Provides an introduction to agentic information retrieval, which is shaped by the capabilities of LLM agents. Discusses different types of cutting-edge applications of agentic information retrieval and challenges. https://t.co/FgBUyrFTeE

2). A Theoretical Understanding of CoT
Finds that adding correct and incorrect reasoning paths in demonstrations improves the accuracy of intermediate steps and CoT. The proposed method, Coherent CoT, significantly improves performance on several benchmarks. In the Tracking Shuffled Objects dataset, Gemini Pro shows a 6.60% improvement (from 58.20% to 64.80%), and in Penguins in a Table, DeepSeek 67B demonstrates an increase of 6.17% (from 73.97% to 80.14%). https://t.co/l93Xch5d4X

3). LongRAG
Enhances RAG's understanding of long-context knowledge which includes global information and factual details. Consists of a hybrid retriever, an LLM-augmented information extractor, a CoT-guided filter, and an LLM-augmented generator. These are key components that enable the RAG system to mine global long-context information and effectively identify factual details. LongRAG outperforms long-context LLMs (up by 6.94%), advanced RAG (up by 6.16%), and Vanilla RAG (up by 17.25%). https://t.co/JB7frSgfvW

4). Reasoning Patterns of OpenAI’s o1 Model
When compared with other test-time compute methods, o1 achieved the best performance across most datasets. The authors observe that the most commonly used reasoning patterns in o1 are divide and conquer and self-refinement. o1 uses different reasoning patterns for different tasks. For commonsense reasoning tasks, o1 tends to use context identification and emphasize constraints. For math and coding tasks, o1 mainly relies on method reuse and divide and conquer. https://t.co/U0kNhAC8m8

5). A Survey on Data Synthesis and Augmentation for LLMs
Provides a comprehensive summary of data generation techniques in the lifecycle of LLMs. Includes discussions on data preparation, pre-training, fine-tuning, instruction-tuning, preference alignment, and applications. https://t.co/OUzwyI6zjJ

6). Beyond Browsing: API-Based Web Agents
Researchers demonstrate that AI agents using both web APIs and browsing capabilities outperform traditional web-only agents by 20% on the WebArena benchmark, achieving a state-of-the-art 35.8% success rate for task-agnostic agents. https://t.co/V2Pm3KAa5B

NetworkX from NVIDIA is one THE most popular Python graph analytics library with ~15K Github starts and 80M downloads monthly.

This library is for working with networks and graphs. It helps analyze connections between things - like social networks, computer networks, or any system where objects are connected to each other.

And now NetworkX just got massively accelerated after its backend integration with NVIDIA's cuGraph.

✨ Up to 500x speedups on large graph workloads in NetworkX with zero code changes.

And it is Zero Code Change Acceleration.

📌 cuGraph is NVIDIA's GPU-accelerated graph analytics library within the RAPIDS ecosystem. The library provides fast graph algorithms on GPUs, supporting property graphs, remote operations, and graph neural networks (GNNs). Works with GPU DataFrames (cuDF) and integrates smoothly with NetworkX-like API.

--------

📌 The traditional bottleneck of NetworkX's pure Python implementation becomes apparent when processing graphs larger than 100K nodes and 1M edges.

📌 And so now cuGraph solves this by offloading supported algorithms to the GPU. PageRank, Louvain community detection, betweenness centrality, and about 60 other algorithms get instant acceleration.

📌 This acceleration enables previously impractical use cases. Fraud detection systems can now process massive transaction networks in real-time. Recommendation engines handle millions of user-item interactions efficiently. Social network analysis scales to entire platforms worth of data on a single machine.

Data pipelines will put you in the top 1% of the market.

If you could only learn one skill for the next decade, I can't think of anything more critical than learning to move and process data at scale.

I like to tell people I'm a Machine Learning Engineer, but in reality, 90% of the value I produce comes from my ability to move data around consistently and correctly.

In the field, we like to use the term "orchestration" when talking about coordinating workflows that move and process data. At a high level, there are three main steps you need to worry about:

1. Getting the data from its source
2. Processing and cleaning that data
3. Delivering the cleaned data to the right place

You might have also heard about "ETL" (Extract, Transform, Load). That's how most people refer to the process above.

Of course, building a simple ETL system isn't complex; most developers can do it without too much trouble. The problem is designing resilient, scalable, and fault-tolerant systems.

You can't code your way to a production-ready orchestration platform (ask me how I know.) I started with AirFlow and eventually moved to @kestra_io because of its event-driven architecture.

Event-driven means you can kick off a workflow automatically based on different triggers. For instance, when somebody uploads a new file to a folder, an app updates a database table, or there's a new message in a queue.

It's hard to summarize everything you get from Kestra, but here are some of the highlights:

• Kestra is free and open-source
• You install it from a Docker container
• Workflows as Code using YAML <--- this is awesome
• Scales to millions of executions
• It integrates with every cloud platform you've seen
• Language agnostic (but I still like Python the most)

Here is a link to their GitHub repository:

https://t.co/h8mWoYcymb

Here are the three things I recommend:

1 - Take a look at their live demo in their GitHub repo
2 - Build a simple workflow (it will take 5 minutes)
3 - Talk to your boss. Where can you plug this into your company?

I started using Kestra at the height of the pandemic. It's an awesome tool, and I'm proud that they are sponsoring my writing. I hope you find it helpful as well.

🚨 [AI RESEARCH] If you're interested in AI ETHICS, the paper "Reconstructing AI Ethics Principles: Rawlsian Ethics of AI" by Salla Westerstrand is a MUST-READ. These are the 'Rawlsian ethics guidelines for fair AI' proposed:

1️⃣ "Developers and deployers of an AI system must ensure that the AI system does not threaten the basic liberties of any individual.
➵ AI systems should not endanger but support the freedom of thought and liberty of conscience.
➵ AI systems should not compromise but support political liberties and freedom of association, such as the right to vote and to hold public office.
➵ AI systems should not harm but support the liberty and integrity of the person, including freedom from psychological oppression and physical assault and dismemberment.
➵ All AI systems should be aligned with the principle of rule of law.

2️⃣ The use and development of AI systems should not negatively impact people’s opportunities to seek income and wealth. If an AI system is used in distribution of advantageous positions, such as recruitment, performance evaluation, or access to education, it needs to be ensured that.
➵ The tool is trained with non-biased training data, or appropriate tools are used to mitigate the biases in the final product if no non-biased training data is available (data bias mitigation),
➵ The outcome of the use of the tool includes an explanation of the grounds for the outcome it produces (explainability), and.
➵ The algorithms used shall encourage neither biased results nor the systematic repetition and amplification thereof in, e.g., the feedback loops of a machine learning system (algorithmic bias mitigation).

*If these conditions cannot be met, AI should not be used in the process.

3️⃣ All inequalities affected by AI systems, such as acquiring a position of power or accumulation of wealth, must be to the greatest benefit of the least advantaged members of society."
