🔗 Top Machine Learning Algorithms For Classification

🌟 InfoSeek: data synthesis for deep research with HCSP formalization. BAAI introduced InfoSeek — an open methodology for data synthesis and a training loop for deep research. Tasks of this class go beyond ordinary fact extraction: the model must decompose the question into subtasks, coordinate multi-step reasoning, and verify answers against sources.

These tasks are formalized as HCSP — hierarchical constraint satisfaction problems, whose solution arises only through sequential narrowing of candidates at multiple levels, where each internal node is itself a subtask, and the dependency between nodes forms a research tree.

The basic idea is simple: data is built around a research tree. The nodes are entities or atomic facts, edges are verifiable relations from Wikipedia and open pages. The synthesis algorithm explicitly manages the structure to eliminate underdetermination or early "short circuits." In HCSP, the answer is formally the intersection of sets defined by current constraints and recursive subquestions; in terms of the tree, the root is the final answer. This approach not only sets the depth and breadth of reasoning but also makes each intermediate step verifiable by specific statements. 🟡The synthesis is performed by a pair of agents. The planner controls global complexity by selecting the goal and type of expansion, while the Browser extracts facts and links from the entity page. Four operations cover the entire lifecycle: 🟢Initialization from the "anchor"; 🟢"Parent blurring" — adding several independent conditions that collectively define a unique answer without inclusions among candidates; 🟢Vertical deepening via hyperlink to increase the tree height; 🟢Question text generation only after each node has a sufficient set of verifiable constraints and the specified complexity metrics are met. Quality is controlled along two axes: complexity and verifiability. Initially, questions are run "head-on": if a powerful base model answers correctly without search, the sample is excluded; about 2% were filtered this way. Then solvability is checked on a fixed set of pages with distractor impurities, and all ambiguity is removed. Result: a dataset with 50K question–answer pairs and 16.5K reasoning trajectories with extraction labels. 🟡Experiments. Tests showed that InfoSeek generalizes beyond the home domain. On classic fact extraction and multi-hop question sets, the compact InfoSeeker-3B model outperforms typical RAG and agent pipelines. On BrowseComp-Plus with a fixed corpus of 100K pages and BM25, accuracy reaches 16.5% with an average of 8.24 search calls, which is higher than Gemini 2.5 Flash, Sonnet 4, and GPT-4.1, and significantly higher than Qwen3-32B and Search-R1-32B. Replacing the training set NQ+HQA with InfoSeek raises accuracy from 3.0% to 16.5% and makes queries meaningfully more frequent. ▶️ The project already provides a dataset, technical report, data tree constructor, and code for SFT training. Plans include RL code and publication of InfoSeeker-3B weights. 📌Licensing: Apache 2.0 License. 🟡Dataset 🟡Arxiv 🖥GitHub

📝 New research on text creativity Scientists have shown: texts created by humans are semantically newer than those generated by AI. 🔎 How it was measured They introduced the metric "semantic novelty" — the cosine distance between adjacent sentences. 🧠 Main findings Human texts consistently show higher novelty across different embedding models (RoBERTa, DistilBERT, MPNet, MiniLM). In the "human-AI storytelling" dataset, the human contribution was semantically more diverse. ✨ But there is a nuance What we call AI "hallucinations" can be useful in collaborative storytelling. They add unexpected twists and help maintain interest in the story. 👉 Conclusion: humans are more innovative, AI is more predictable, but together they enhance each other. 🔗 Details

AI vs ML vs Deep Learning 🤖 You’ve probably seen these 3 terms thrown around like they’re the same thing. They’re not. AI (Artificial Intelligence): the big umbrella. Anything that makes machines “smart.” Could be rules, could be learning. ML (Machine Learning): a subset of AI. Machines learn patterns from data instead of being explicitly programmed. Deep Learning: a subset of ML. Uses neural networks with many layers (deep) powering things like ChatGPT, image recognition, etc. Think of it this way: AI = Science ML = A chapter in the science Deep Learning = A paragraph in that chapter.

🔟 things to know before diving into AI automation An author from Reddit built over 100 workflows and highlighted the most important lessons: 1. Start with simple scenarios — 10 minutes of benefit is better than 10 hours of complexity. 2. Document the process: screenshots and errors are your portfolio. 3. Learn to work with HTTP requests right away — it opens access to almost everything. 4. Don’t call yourself an "expert," say specifically: "I help businesses save time." 5. Know how to say no: sometimes "no" opens the way to more profitable projects. 6. Always think about errors: APIs crash, data breaks. 7. Share failures — they build more trust than perfect cases. 8. Stable income comes not from setup, but from support and improvements. 9. Networking is half the success. Projects come through colleagues. 10. Automate yourself first: the best argument is your own example. 💡 The main thing: businesses don’t need beautiful workflows, but results — for example, "minus 15 hours of routine per week." 🔗 Full post
