As a card-carrying AI hater, I feel it my duty to point out when it’s actually useful, and Dan Cohen presents such a case:
“All goes in the usual monotonous way.” That is the depressed sigh of George Boole in a letter to his sister Maryann in 1850. It was the spark for my book Equations from God: Pure Mathematics and Victorian Faith. Boole, the English mathematician who gave us the logic at the heart of the digital device you are reading this on, was teaching in Cork, Ireland at the time. On a cold December day, he wrote to Maryann about his feelings of profound loneliness. In a city that was on edge from religious strife and famine, he played piano at home to an empty room, and took long walks by himself. At the end of the day, he retreated to his equations, which seemed to transcend the petty differences of humanity.
But before developing my thesis about the fervent emotions behind Boole’s seemingly cold mathematical logic, I first had to read his damn handwriting. Talk about monotony! There were hundreds of letters and notebooks in his drifty scrawl. In retrospect, Boole’s handwriting is actually not that bad; I’ve encountered far worse since reading his in Cork. And it helped that I had taken a brief course on paleography, the art of deciphering handwritten historical documents. But it would have saved me a lot of time getting to the interesting interpretive phase of my research if a computer could have converted his handwriting into machine-readable text, as it already could for typeset text through a process called optical character recognition (OCR).
Since I wrote that book, university and industry labs have been trying to solve the incredibly difficult problem of handwritten text recognition (HTR). OCR quickly approached 99% accuracy for digitized books, whereas even the best HTR systems struggled to reach 80% — two incorrect words out of every ten. The issue is obvious: unlike the rigorous composition of books, handwriting is highly variable by author, and words are often indeterminate and irregularly arranged on a page.
He uses George’s letter to Maryann as a test, which most approaches fail; then he hits the jackpot:
