Semantic Smoothing for Language Models via Distribution Estimation and Embeddings
Haricharan Balasundaram, Swathi Shree Narashiman, Pranay Mathur +1
We propose semantic smoothing, a smoothing method for language models that uses embeddings to share statistical observations across semantically similar contexts. The starting poin…

Distribution Estimation with Side Information
Haricharan Balasundaram, Andrew Thangaraj
We consider the classical problem of discrete distribution estimation using i.i.d. samples in a novel scenario where additional side information is available on the distribution. I…

Learning to Transmit Over Unknown Erasure Channels with Empirical Erasure Rate Feedback
Haricharan Balasundaram, Krishna Jagannathan
We address the problem of reliable data transmission within a finite time horizon over a binary erasure channel with unknown erasure probability. We consider a feedback model w…
