  • James Bond and the Struggle with Common Sense

    Countless times, James Bond had guided my thoughts and taught me lessons I would never forget.

I happened upon James standing in the middle of a busy road, completely oblivious to the torrent…

  • To find a needle in a haystack

    Upon entering the room, I was startled to find James Bond on all fours, frantically crawling on the floor. Fear gripped me as I wondered if the building was besieged by enemies, poised to unleash a barrage of gunfire. “What’s wrong? Are we under attack?” I stammered, my voice barely audible in the tension of…

  • Art of prophesy

    One of the most exhilarating scenes in spy movies is the daring escape of a secret agent amidst a hailstorm of enemy gunfire. A cunning agent avoids a direct path, instead weaving through a serpentine course that makes targeting him a daunting task for his adversaries, who struggle to anticipate his next move. James interjected,…

  • On the Merits of Indolence

    What was never clear to me about James Bond’s personality was why he was dubbed ‘agent 007.’ I queried him once if there were at least six other super-agents comparable to him in skills, intelligence, and experience. He responded, ‘This nickname actually has another origin. My colleagues jest that I possess zero motivation, zero concentration,…

  • Squeezing dimensions

    I’ve always admired James Bond’s knack for wriggling out of impossible situations. I said to him: “It’s quite remarkable how smoothly you scale fences, leap from windows, and bulldoze through walls. I find myself wishing I could be a bit more like you…” James’ response, however, was less than encouraging. “You wish to experience claustrophobia?”…

  • Accuracy of PCA

    Once, I asked James Bond where his most difficult mission took place — was it in Turkey, Mexico, or Russia? “In Great Britain, when I was promoted to the central analytical office of MI-6,” he answered. “Were the headquarters suddenly attacked by an army of foreign spies?” “I would have wished for that. Instead, I…

  • ICA vs PCA

    Once, I asked James Bond what was most important for a secret agent: shooting smartly or running quickly. “None of them,” answered Bond. “The most important thing is to be invisible. You should not be noticed by anybody who is searching for you.” “So, should you be dressed as a very average person?” “Not exactly,”…

  • PCA reveals trends

    This story takes us back to a time when James Bond was sent undercover as an MI-6 agent to a highly classified school. His mission was to observe the participants closely. Bond meticulously tracked the grades of all the students and created tables where each row represented a student, and each column represented their scores…

  • How much noise can we remove by PCA?

    Y’all probably heard about Principal Component Analysis (PCA) and how it can be used to clean up noisy datasets. This can be done with our software, for instance. But have you ever wondered how it actually works? And more importantly, can it eliminate all the noise or just a fraction? Well, this post is here…
