On a few pitfalls in KL divergence gradient estimation for RL
We point out a few pitfalls in implementing gradient estimation for KL divergence in RL training for LLM, as seen in a number of open source projects and papers. The first major pitfall is to differentiate through the KL estimate as loss functions to minimize KL divergence. We show that such implementations are generally incorrect and do not produce the desired KL gradient. Secondly, we show that some implementations do not account for the sequential nature of the estimation problem and produce…

"We can argue over the specific time at which empathy in software design entered the software engineering body of knowledge. Barry Boehm’s 1999 paper “Escaping the Software Tar Pit” introduces the modified golden rule to software engineering:
> Do unto others as you would have them do unto you — if you were like them."

An optimal class of domains permitting inner boundaries in a divergence theorem for rough integrands
The divergence theorem on an open domain $U \subset \mathbb{R}^m$ of finite measure is investigated for the rough class $\mathcal{DM}_\infty(U)$ of bounded vector fields $u \, \colon \, U \to \mathbb{R}^m$ with a finite Radon measure divergence. Let $\mathcal{DB}(U)$ denote the closure of $\mathcal{DM}_\infty(U)$ in the Lebesgue space $L_\infty(U)$. Equivalent conditions are proved for the domain $U$ to admit the divergence theorem \begin{equation} \exists ! \ell \in \mathcal{DB}'(U) \, \colon …

The Science of Well-Being — Yale Youth Ministry Institute
The most popular course in the more than three-century history of Yale, “The Science of Well-Being” highlights research that reveals misconceptions about what makes us happy — and the concrete steps we can take to live a more fulfilling life. Yale Professor Laurie Santos has taken this course and created a new version specifically for high school aged youth. Hear the conversation about how youth (and youth workers) can improve their mental and physical health.

Geometric Jensen-Shannon Divergence Between Gaussian Measures On Hilbert Space
This work studies the Geometric Jensen-Shannon divergence, based on the notion of geometric mean of probability measures, in the setting of Gaussian measures on an infinite-dimensional Hilbert space. On the set of all Gaussian measures equivalent to a fixed one, we present a closed form expression for this divergence that directly generalizes the finite-dimensional version. Using the notion of Log-Determinant divergences between positive definite unitized trace class operators, we then define a…
