  • Solving Zero-Frequency in NLP with Smoothing Techniques
    Laplace smoothing is the simplest form of smoothing by adding 1 to the count of every n-gram (including those with zero counts) and adjusting the denominator accordingly (w: n-grams, C: count of
  • Laplace Smoothing : Improve Naive Bayes Models - Analytics Vidhya
    Q1 What is Laplace smoothing in natural language processing? Laplace smoothing is a technique in NLP that prevents zero probability estimates for unseen n-grams, improving the accuracy of language models
  • Laplace smoothing in Naive Bayes algorithm - Towards Data Science
    Laplace smoothing is a smoothing technique that handles the problem of zero probability in Naïve Bayes Using Laplace smoothing, we can represent P (w’|positive) as Here, alpha represents the smoothing parameter, K represents the number of dimensions (features) in the data, and N represents the number of reviews with y=positive
  • From Zero to Hero: Laplace Additive Smoothing for Naive Bayes . . .
    The Solution -Laplace Smoothing Laplace Additive Smoothing is used to alleviate the zero-probability problem Adding a small constant value (α) to each count ensures that no probability
  • Additive Smoothing Techniques in Language Models
    Laplace Smoothing in Language Models Laplace Smoothing is a specific case of additive smoothing where the smoothing parameter α is set to 1 The primary goal of Laplace Smoothing is to prevent the probability of any n-gram from being zero, which would otherwise happen if the n-gram was not observed in the training data
  • Model Smoothing to Prevent Zero-Probabilities in . . .
    In this post, we have discussed two popular model smoothing techniques: Laplace Smoothing and Katz Back-off Smoothing Both techniques help address the data sparsity problem in language models by preventing zero probabilities for unseen words or n-grams
  • Laplace Smoothing: How Smoothing Techniques Transform . . .
    Laplace Smoothing works by adjusting the counts in the probability formula to ensure that no event has a probability of zero Essentially, it adds a constant (usually 1) to the count of
