Summary: Part I of Sutton and Barto's book covers fundamental Reinforcement Learning techniques, while Part II focuses on using deep neural networks for approximate solutions. The upcoming series will benchmark algorithms in Gridworld environments to identify the most effective methods.
Text classification is vital for various applications. Large language models offer efficiency, but custom ML models may provide higher accuracy.
Business leaders often have high expectations for AI, but face limited results. To truly leverage AI, understanding its core capabilities - Think, Know, Act - is crucial. AI evolves from an assistant to a strategic collaborator when it can reason, learn, and take meaningful actions towards business goals.
Chris Pelkey, deceased in 2021, speaks on forgiveness in AI video fed by his sister. Despite his death, Pelkey 'appeared' in court to confront his killer.
Alan Turing's codebreakers cracked the Enigma code with "Bombes" machines in WWII. Modern computing could easily decipher it now.
Summary: This article clarifies the misconceptions around backpropagation by explaining the total-derivative and introducing the vector chain rule to simplify complex calculations in neural networks. The implementation of vector calculus in backprop equations optimizes the computation of gradients for all weights in a layer simultaneously, enhancing efficiency in training models.
Amazon Bedrock Evaluations introduces LLM-as-a-judge technique for evaluating models and RAG systems, enabling custom metrics for tailored assessments. Organizations can now systematically evaluate models and applications with automated, human-like quality at scale, using built-in or custom metrics.
OpenAI backtracks on for-profit transformation, nonprofit arm to control ChatGPT. Decision made after input from civic leaders and attorneys general.
AI labs are preparing for rogue AIs colluding against humans, but the real threat is AI making humans obsolete in all aspects of life. AI could replace humans economically, culturally, and socially, leaving us wondering our place in a world where AI does everything better.
Amazon faces ethical responsibility to prevent chatbot-written books on sensitive topics like managing ADHD. AI-generated works flood marketplace with misleading information, from travel guides to mushroom foraging books.
Tech billionaires like Musk and Bezos have always had a far-right libertarian core, not a sudden shift in ideology. Silicon Valley's venture capitalists and CEOs have long embraced a quasi-religious belief in tech salvation, despite outward political affiliations.
Knowledge Graphs connect concepts, entities, and relationships to enhance LLM performance in information retrieval. GraphRAG uses graph-based knowledge representation to improve LLM reasoning beyond traditional vector approaches, enabling inter-document level reasoning for more effective information retrieval.
