Typo Detection Part V: Comparing Matrices

This entry is part 5 of 5 in the series Typo detection

In the last couple of posts, I considered whether the Frobenius distance/norm or Pearson correlation coefficient were appropriate ways to compare my 4 POS transition matrices. Also, I have produced similarity matrices and scatter plots as more visual ways of trying to garner anything useful – I think the scatter GIFs are probably […]


Typo Detection Part IV: Comparing Matrices with The Pearson coefficient.

This entry is part 4 of 5 in the series Typo detection

I cut the last post, where I was looking at ways to quantify the similarity between two matrices, I cut things short – the post was getting too long-winded and math-ey. This one might be a little too (we’ll see)…but hopefully, it’ll be short. I covered using the matrix norm for comparing my […]


Typo Detection Part III Comparing Matrices with the Vector Distance

This entry is part 3 of 5 in the series Typo detection

In the last typos detection post I worked out the POS transition matrices for 3 classic books, to serve as comparisons of exemplary writing to compare to my own matrix. What I have done now is done a bit of post-processing on those matrices to try and compare them. To be honest […]


Typo Detection Part II Other Writers

This entry is part 2 of 5 in the series Typo detection

I have been playing with something to try and detect annoying typos. It uses a natural language processor (at the moment I’m using Stanford Parser) to form a transition matrix for the Parts of Speech (POS) I use. For input data, I used my writing from this blog. At the end of […]


Typo Detection

This entry is part 1 of 5 in the series Typo detection

Typos There is nothing worse than when you spend hours, days (weeks?) writing something and then you revisit it and find it peppered with dumb, and seemingly inescapable, typos. It really bugs me: If I see those typos in somebody else’s work I automatically think, “sloppy”, and; No matter how […]


(Grrrrr!)eprap Pololu Driver Upgrade

The (Driver) Issues My Prusa i3 really is now becoming a labour of love, rather than something that will ever be useful. Despite my last bout of tinkering, something was still broken. The Halcyon days of perfect prints seem long in the past now – did they ever even exist I […]


Subaru: Front Grille GT

This entry is part 7 of 7 in the series Subaru Legacy

Who Needs a Front Grille Badge? We do! So in my effort to spruce up my car I came across the S402 Legacy. One of the cosmetic accoutrements it had was the S402 badge on the front grille. Custom Front Badge I thought a bit about making my own badge. I […]


DIY CNC Router – Post 7: (Hot and Melting) Wires

This entry is part 7 of 7 in the series DIY CNC Machine

CNC Wiring: What I Thought Was a Good Idea I had neatly done all my wiring using old style computer serial leads and plugs (technically called a DE-9 D-Subminiature connector I learnt) and my little control boxes made from wine boxes. The serial connectors have nine pins so I was using four for […]


Irritating RepRap

This entry is part 3 of 3 in the series RepRap

The Irritation that is My 3D Printer If I had to write a list of things that I am finding irritating right now, it would be quite long: Long enough, actually, for me to categorize the things on it, and list them: a meta-list. Three of those categories would be: (Paid/career) […]


Subaru: Sound system upgrade

This entry is part 6 of 7 in the series Subaru Legacy

The OEM speakers and such in my Legacy were not up to much. I took a look at them in the doors and found they were shot: the paper cones had rotted away and the terminals were rusty. Plus, I’ve read, the OEM sound systems have room for improvement anyway. Anyway […]
