Article Daily Dose of Data Science | Avi Chawla | Substack · 1y How Do LLMs Work? Large Language Models work by predicting the next word in a sequence using conditional probability. They calculate probabilities for each possible next word given the previous context, then select the most likely candidate. To avoid repetitive outputs, LLMs use temperature sampling which adjusts the probability distribution - low temperature produces focused, predictable text while high temperature creates more random, creative outputs. The models learn high-dimensional probability distributions over word sequences, with trained weights serving as the parameters of these distributions. 31 6. 6 [](/posts/correlation-vs-cosine-similarity-wgaju1vlw "Correlation vs. cosine similarity") Article The Palindrome · 1y Correlation vs. cosine similarity Explores the key differences between Pearson correlation and cosine similarity, two statistical measures for quantifying relationships between variables. While both are based on dot products, correlation performs double normalization (mean-centering and variance scaling) while cosine similarity only normalizes by magnitude. Through mathematical explanations and Python simulations, the post demonstrates that these measures can yield dramatically different results depending on data scaling and offsets. Correlation is recommended when measurement units are arbitrary or different, while cosine similarity is preferred when variables share meaningful units, particularly in machine learning applications with vector embeddings. 24 7. 7 [](/posts/99-of-developers-don-t-get-poisson-distribution-cfevj0ude "99% of Developers Don't Get Poisson Distribution") Video The Coding Gopher · 1y 99% of Developers Don't Get Poisson Distribution Many developers overlook the importance of understanding concepts like the Poisson distribution, which is crucial for modeling rare events happening at a constant rate in a fixed interval. This distribution is applicable in various fields, such as biology and physics, where it helps assess probabilities of events like mutations or decay. Understanding these statistical principles can enhance logical reasoning in software development. 23 3 8. 8 [](/posts/solve-markov-decision-processes-with-the-value-iteration-algorithm---computerphile-lbsmnunc1 "Solve Markov Decision Processes with the Value Iteration Algorithm - Computerphile") Video Computerphile · 2y Solve Markov Decision Processes with the Value Iteration Algorithm - Computerphile The value iteration algorithm is a method for solving Markov decision processes (MDPs) to produce optimal action decisions. MDPs model decision-making problems, particularly those under uncertainty. The algorithm iteratively computes the values of states to find the policy that minimizes cost or maximizes reward. It is essential for decision-making models where dynamic programming techniques are applied to achieve the best outcome. 23 9. 9 [](/posts/the-anatomy-of-logistic-regression-enrhebfhc "The Anatomy of Logistic Regression") Article The Palindrome · 1y The Anatomy of Logistic Regression Logistic regression transforms geometric relationships into probability predictions through a step-by-step process. Starting with linear transformation (ax + b) to create logits, the model applies exponential functions and sigmoid activation to map any real number to a probability between 0 and 1\. The geometric aspect becomes clear in higher dimensions where the decision boundary forms lines or planes, with logits representing signed distance from these boundaries. This fundamental approach demonstrates how machine learning models convert spatial relationships into probabilistic predictions. 20 10. 10 [](/posts/the-only-data-science-roadmap-you-need-to-get-a-job-gb1pwrkq8 "The ONLY Data Science Roadmap You Need to Get a Job") Article Towards Data Science · 1y The ONLY Data Science Roadmap You Need to Get a Job A comprehensive learning roadmap for aspiring data scientists covers six core areas: statistics (summary statistics, probability, hypothesis testing), mathematics (calculus and linear algebra), programming (Python and SQL), technical tools (Git, command line, package management), machine learning fundamentals (regression, decision trees, neural networks), and optional deep learning concepts.
