What is Information Theory in Machine Learning?
Information Theory in Machine Learning applies entropy, mutual information, and compression principles to quantify data dependencies, model complexity, and learning bounds in algorithms.
This subtopic connects Shannon's information measures to Valiant's learnability framework (Valiant, 1984, 3231 citations) and compression techniques (Ziv & Lempel, 1978, 3412 citations). Key concepts include VC dimension linking to information capacity (Blumer et al., 1989, 1838 citations) and real-number computation models (Blum et al., 1989, 1053 citations). Over 20 papers from the list explore these intersections.
Why It Matters
Information theory provides PAC-learnability bounds enabling efficient feature selection in high-dimensional data (Valiant, 1984). Compression via variable-rate coding (Ziv & Lempel, 1978) improves generative model efficiency and interpretability. Cucker & Smale (2001) foundations support statistical learning guarantees in kernel methods and neural networks, impacting scalable AI deployment.
Key Research Challenges
Linking Entropy to Learnability
Quantifying how sequence compressibility predicts generalization remains open (Ziv & Lempel, 1978). Valiant's model (1984) lacks direct entropy bounds for non-i.i.d. data. Blumer et al. (1989) VC analysis needs extension to infinite hypothesis spaces.
Computational Complexity of Measures
Estimating mutual information in high dimensions exceeds polynomial time (Goldreich et al., 1986). Blum et al. (1989) real-number NP-completeness complicates exact computation. Smale's foundations (2001) highlight sampling limits for precise bounds.
Scalable Compression in Learning
Variable-rate encoders struggle with real-time ML adaptation (Ziv & Lempel, 1978). Backus (1978) critiques von Neumann limits on functional compression. Graham's timing bounds (1969) reveal multiprocessing anomalies in parallel entropy estimation.
