Revolutionizing AI Efficiency: How Microsoft’s LLMLingua-2 is Changing the Game with 8x Less Memory

Publié le par
  • LLMLingua-2 is a novel compression technology developed by Microsoft Research, achieving state-of-the-art results with 8 times less GPU memory on tasks typically handled by models like GPT-4.
  • It introduces innovative approaches such as « Data Distillation, » « Bidirectional Token Classification, » and optimized compression objectives to efficiently compress prompts without losing key information.
  • The technology has shown superior performance across various language tasks and demonstrated remarkable generalization across different LLMs and languages, from GPT-3.5 to Mistral-7B and from English to Chinese.
  • Compared to existing prompt compression methods, LLMLingua-2 is 3 to 6 times faster, accelerates end-to-end inference by 1.6 to 2.9 times, and significantly reduces GPU memory usage by a factor of 8.
  • This advancement represents a significant step forward in making language AI more practical and scalable for real-world applications, demonstrating Microsoft Research’s leadership in the field.

Category Encoders

Publié le par

A set of scikit-learn-style transformers for encoding categorical variables into numeric with different techniques.

Category Encoders is a Python library for encoding categorical variables for machine learning tasks. It is available on contrib.scikit-learn.org and extends the capabilities of scikit-learn’s preprocessing module.

The library provides several powerful encoding techniques for dealing with categorical data, including:

  • Ordinal encoding: maps categorical variables to integer values based on their order of appearance
  • One-hot encoding: creates a binary feature for each category in a variable
  • Binary encoding: maps each category to a binary code
  • Target encoding: encodes each category with the mean target value for that category
  • Hashing encoding: maps each category to a random index in a hash table

Category Encoders also supports a range of advanced features, such as handling missing values, combining multiple encoders, and applying encoders to specific subsets of features.

Overall, Category Encoders is a useful tool for preprocessing categorical data and improving the accuracy and performance of machine learning models.
