High-Level Summary of X’s For You Algorithm (Core Design – Mostly Unchanged) Core Idea X builds the For You feed by mixing: Posts from accounts you follow (In-Network) High-quality posts from accounts you don’t follow (Out-of-Network) Then uses AI to rank everything and show you what you’re most likely to engage with. Main Components Home Mixer: Central orchestrator that manages the entire pipeline (hydration, retrieval, filtering, scoring, blending, etc.). Thunder: In-Network source — fetches recent posts from people you follow (near real-time). Phoenix Retrieval: Out-of-Network source — ML-powered search that finds thousands of relevant candidates across the entire X corpus (billions of posts). Phoenix Scorer: Transformer model based on Grok architecture — predicts the probability you will Like, Reply, Repost, Click, etc. for each candidate. Key Characteristics Minimal hand-crafted rules: Very few traditional heuristics or engineered features. Almost everything is driven by the learned model based on your real behavior (past interactions, follows, topics, etc.). Result: Highly personalized feed that favors engagement and relevance over pure chronology. In short: Thunder supplies familiar content Phoenix finds fresh interesting content → Grok-style model scores everything → Home Mixer assembles the final feed. This high-level architecture remains stable. Recent updates mainly improve usability, add safety (Grox), and enhance ads blending. #XAlgorithm #ForYouFeed #GrokAI #PhoenixModel #OpenSource #xAI #TwitterAlgorithm #RecommendationSystem

I built my own Movie Recommendation System. You know how Netflix always seems to know what you want to watch next? I decided to build the engine behind that idea from scratch. #MachineLearning #RecommendationSystem #Python #NLP #TFidf #CosineSimilarity #DataScience

I built a smart product recommendation system for an e-commerce page 🛒 No tags. No manual mapping. Just product data → vectors → similarity → suggestions. How it works: • Convert product text into embeddings (NLP) • Compute cosine similarity • Show the most related items instantly on the product page Result: users discover products instead of searching for them. Turning a normal store into a smart store. #BuildInPublic #MachineLearning #NLP #RecommendationSystem #FullStack #Nextjs

AI in education requires distinguishing between consumer attention-stealing uses (e.g., #recommendationsystem) and creative uses of AI that support critical thinking and collaborative problem-solving, among other #5c21 skills. 👉 #ppai6
The technology is changing how children play, how they are supervised and with whom—or what—they share confidences and form friendships. Regulators are gearing up to protect youngsters economist.com/briefing/2025/…

BiBLDR: Bidirectional Behavior Learning for Drug Repositioning 1.BiBLDR reframes drug repositioning as a behavioral sequence prediction task, inspired by recommendation systems. Instead of modeling associations via graphs, it learns from interaction patterns between drugs and diseases, enabling stronger generalization—especially for new drugs. 2.The method constructs bidirectional behavioral sequences, representing both drug-to-disease and disease-to-drug associations. This dual perspective captures more complete interaction signals than unidirectional models. 3.BiBLDR is the first to apply Transformer architecture to drug repositioning using behavior sequences. The model leverages multi-head self-attention to extract complex semantic patterns in both drug and disease behavioral contexts. 4.A two-stage learning strategy is proposed:   • Stage I builds latent prototype spaces for drugs and diseases using similarity data and Siamese networks.   • Stage II uses these prototypes, enriched with explicit similarity information, as input to the Transformer to predict associations. 5.Similarity fusion plays a central role. BiBLDR integrates numerical similarity values directly into prototype features within behavioral sequences, enhancing contrast between similar and dissimilar entities. 6.The model introduces a logarithmic weighting scheme in behavioral sequences to emphasize positive associations during training, aiding contrastive learning and mitigating sparsity. 7.BiBLDR demonstrates state-of-the-art performance on three benchmark datasets (Gdataset, Cdataset, LRSSL), outperforming both classical and deep learning methods, including GCN-based approaches, in AUROC and AUPRC. 8.In cold-start scenarios, where novel drugs have no known associations, BiBLDR outperforms existing methods with a large margin (e.g., AUPRC of 0.6194 vs 0.3484), validating its ability to generalize beyond observed data. 9.BiBLDR maintains robustness under extreme data sparsity, thanks to the independent prototype construction stage, which does not rely on the association matrix’s density. 10.Ablation studies confirm the value of each design component: bidirectional modeling, prototype spaces, similarity fusion, and Transformer layers all significantly contribute to performance. 11.In real-world case studies on lung cancer and hypertension, BiBLDR achieved high hit rates (80%–90%) in top-ranked predictions. For unverified predictions, molecular docking experiments confirmed strong binding affinities. 12.In conclusion, BiBLDR offers a novel and effective direction for drug repositioning research, combining strengths of recommender systems, prototype learning, and attention-based modeling. 💻Code: github.com/Renyeeah/BiBLDR 📜Paper: arxiv.org/abs/2505.23861v1 #DrugRepositioning #Transformer #DeepLearning #BiomedicalAI #RecommendationSystem
