When you type a query into a search engine, something has to decide which documents are really important – and how to rank them. BM25 (Best Matching 25)the algorithm that powers search engines like Elasticsearch and Lucene, has been the leading answer to that question for decades. It scores by looking at three things: how … Read more
In this tutorial, we use a reinforcement learning agent RLaxa research-oriented library developed by Google DeepMind to build reinforcement learning algorithms with JAX. We combine RLax with JAX, Haiku, and Optax to build a Deep Q-Learning (DQN) agent that learns to solve the CartPole environment. Instead of using a fully packaged RL framework, we assemble … Read more

Deploying a new machine learning model to production is one of the most important phases of the ML lifecycle. Even if the model works well in validating and testing data sets, directly replacing an existing production model can be risky. Offline experiments rarely capture the full complexity of a real-world environment—data distributions can change, user … Read more
In this tutorial, we build a large uncertainty-aware linguistic modeling system that not only generates answers but also estimates confidence in those answers. We use a three-stage logic pipeline where the model first generates feedback and a self-reported confidence and correction score. We then introduce a self-evaluation step that allows the model to self-criticize and … Read more
NVIDIA has announced the release of Nemotron-Cascade 2open weight 30B Mixed-Expert (MoE) model with 3B activated parameters. The model focuses on increasing ‘intellectual density,’ bringing advanced imaging capabilities to a fraction of the parameter scales used by frontier models. Nemotron-Cascade 2 is the second LLM with open access Gold Medal level performance in the 2025 … Read more

In the current state of Retrieval-Augmented Generation (RAG), the main bottleneck for developers is no longer the large language model (LLM) itself, but the data import pipeline. For software developers, converting complex PDFs into a format that LLM can consult is often a high-latency, often expensive task. LlamaIndex has just been launched LiteParseis an open-source, … Read more

Google has officially released the Colab MCP Serverthe implementation of the Model Context Protocol (MCP) that allows AI agents to interact directly with the Google Colab environment. This integration goes beyond simple code generation by giving agents structured access to create, modify, and execute Python code within cloud-managed Jupyter notebooks. This represents a transition from … Read more
