Shrink to Win: Regularization’s Role in Model Success

Mathuranathan — Sat, 01 Mar 2025 08:11:48 +0000

Overfitting? Shrink your model! Regularization prevents memorization, enabling true learning & robust success. Discover how. A central problem in machine learning is to develop algorithms that work well both on training data and on new inputs (test data). Most machine learning tasks can be generalized as the estimation of a function \(\hat{f}(X)\) that maps the ... Read more

Model Distillation Explained: How DeepSeek Leverages the Technique for AI Success

Mathuranathan — Wed, 26 Feb 2025 08:45:06 +0000

Model distillation, also known as knowledge distillation, is a supervised learning technique that condenses the capabilities and thought processes of a large, pre-trained “teacher” model into a smaller “student” model. This allows the student model to achieve comparable performance to the teacher model, but at a lower cost and with faster performance. Chinese AI lab ... Read more

Orthogonality of OFDM

Mathuranathan — Thu, 02 Jun 2022 04:02:00 +0000

OFDM, known as Orthogonal Frequency Division Multiplexing, is a digital modulation technique that divides a wideband signal into several narrowband signals. By doing so, it elongates the symbol duration of each narrowband signal compared to the original wideband signal, effectively minimizing the impact of time dispersion caused by multipath delay spread. OFDM is categorized as ... Read more
