Michael Ekstrand<p>New at my blog: I'd been bothered for a few years now in teaching <a href="https://hci.social/tags/recsys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>recsys</span></a> by the need for a biased lift computation for informative product-relatedness measures that aren't dominated by low-information items. So this term, I sat down to solve the problem. <a href="https://md.ekstrandom.net/blog/2025/01/biased-lift" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">md.ekstrandom.net/blog/2025/01</span><span class="invisible">/biased-lift</span></a></p>
Michael Ekstrand<p>Do you appreciate news?

Michael Ekstrand<p>What if <a href="https://hci.social/tags/RecSys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RecSys</span></a> put as much energy into explicitly anti-fascist recommendations as it does into viewpoint-diverse recommendations?</p><p>What if the goal isn’t to model tolerance for diversity, but to identify items that will increase the reader’s empathy and understanding of their neighbors and their needs?</p><p>This paper provides some thoughts applicable to that direction. <a href="https://doi.org/10.1108/JD-01-2020-0002" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">doi.org/10.1108/JD-01-2020-000</span><span class="invisible">2</span></a></p>

Michael Ekstrand<p>Do GPUs have an equivalent of "cpu-seconds" like getrusage() returns for CPU utilization?

Michael Ekstrand<p>In the main track poster session, we have a poster for work led by my recently-graduated PhD Ngozi Ihemelandu on multiple comparisons in IR evaluation at <a href="https://hci.social/tags/recsys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>recsys</span></a> scale. We recommend using Benjamini-Yekuteili, or Bonferoni if sample size is huge & the simplicity is preferred. <a href="https://md.ekstrandom.net/pubs/ecir-mcp" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">md.ekstrandom.net/pubs/ecir-mc</span><span class="invisible">p</span></a></p>

Michael Ekstrand<p>This one is led by my student Ngozi Ihemelandu, and is the last piece of her dissertation that she defended this week. It looks at multiple-comparison corrections and assesses their performance for search and especially <a href="https://hci.social/tags/recsys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>recsys</span></a> experiments. TL;DR using Benjamini-Yekutieli instead of Bonferonni is a good default. <a href="https://md.ekstrandom.net/pubs/ecir-mcp" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">md.ekstrandom.net/pubs/ecir-mc</span><span class="invisible">p</span></a></p>
Michael Ekstrand<p>He also touches on <a href="https://hci.social/tags/recsys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>recsys</span></a> and advertising: ‘Moreover, from the digital footprints spread throughout the Internet, technologies …[can] control mental and relational habits for commercial or political purposes, often without our knowledge, thus limiting our conscious exercise of freedom of choice. In a space like the Web, marked by information overload, they can structure the flow of data according to criteria of selection that are not always perceived by the user.’</p>
