Codebook LLMs: Evaluating LLMs as Measurement Tools for Political Science Concepts

Political Analysis
Codebooks—documents that operationalize concepts and outline annotation procedures—are used almost universally by social scientists when coding political texts. To code these texts automatically, researchers are increasingly turning to generative large

Codebook+: A New Module for Creating Discriminative Codebooks

Multimedia and Expo, 2007 IEEE International Conference on, 2007
In this paper, we introduce a new module, Codebook+, into a classical framework which combines bag-of-words image representation with probabilistic latent semantic analysis (pLSA) for unsupervised object categorization. This new module makes the framework less sensitive to the image sampling methods as well as improves its performance.

Hierarchical codebook design for fast search with Grassmannian codebook

2012 IEEE Wireless Communications and Networking Conference (WCNC), 2012
It has been well known that channel aware systems (closed-loop) have better performance than channel unknown systems (open-loop). In order to know channel in the transmitter, receivers should send own channel information the transmitter through reverse channel.

Multilingual weighted codebooks

2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008
In this paper we present an approach for speech recognition of multiple languages with constrained resources on embedded devices. Examples of such systems are navigation systems, mobile phones and MP3 players. Speech recognizers on such systems are typically to-date semi-continuous speech recognizers, which are based on vector quantization.

Structured Stochastic Codebook and Codebook Adaptation for CELP

1993
Since its introduction in 1984, Code Excited Linear Prediction (CELP) [1] has been intensively investigated as a promising coding algorithm for providing good quality speech at low bit rates. CELP is the name for a class of coding algorithms that employs vector quantization (VQ) using a perceptually weighted error criterion measured in an Analysis-by ...

Codebook Edge Detection

Graphical Models and Image Processing, 1993
Abstract This paper deals with the problem of extracting edge structure from compressed image representations. As image coding techniques become more common in image manipulation systems, it is reasonable to develop methods of analyzing an image using operations on the compressed image representation rather than the reconstructed image.
