Predicting the NBA Champion with Machine Learning
- Using data and Machine Learning, it is possible to predict the NBA Champion at the end of the regular season.
- The approach reframes the problem as a regression task, predicting the Champion Share of each team.
- Data from 1984 to 2024 seasons were used to train the model with a focus on relative metrics and team/player statistics.
- Champions tend to come from top seeds with higher winning percentages and slightly higher average age.
- The model used was LightGBM, achieving an RMSE of 0.184 and an R² score of 0.537 on the test dataset.
- Important features influencing the model's predictions include seed, win percentage rank, and team-level statistics.
- The model correctly predicted two of the last three NBA champions and favors the Boston Celtics for the 2025 playoffs.
- Injuries remain a challenge for prediction models, impacting playoff outcomes significantly.
- While no model is perfect, data-driven approaches can provide valuable insights into playoff success in basketball.
- The analysis shows the potential of machine learning in predicting sports outcomes while acknowledging the unpredictability of sports.

Ethically trained AI startup Pleias releases new small reasoning models optimized for RAG with built-in citations
- French AI startup Pleias has released two small reasoning models optimized for retrieval-augmented generation, citation synthesis, and structured multilingual output.
- The models, Pleias-RAG-350M and Pleias-RAG-1B, are based on the Pleias 1.0 family of language models and available in CPU-optimized GGUF format.
- These models aim to provide cost-effective alternatives to large-scale language models without compromising traceability, multilingual capabilities, or structured reasoning workflows.
- Pleias positions their design choice of built-in source citation as an ethical imperative that aligns with regulatory demands for explainable AI.
- The Pleias-RAG models can autonomously assess queries, determine complexity, and decide on responses based on source adequacy, offering structured and reasoned answers.
- Despite their small size, the Pleias-RAG models exhibit behavior associated with larger systems, showcasing efficient performance on standard CPUs.
- In benchmark evaluations, these models outperform larger models on tasks like HotPotQA and show strength in multilingual scenarios with minimal performance degradation.
- The models' multilingual support is achieved through careful tokenizer design and adversarial training exercises for language-switching.
- Pleias envisions their models being used to augment the performance of existing AI models in orchestration settings, highlighting their cost-effectiveness and complementarity.
- The models are released under the Apache 2.0 license, emphasizing commercial reuse and integration into various systems and applications.
