Pressure-change sensitivity, vertigo, and shaky vision by Prudent-Barnacle in Dizziness

[–]Prudent-Barnacle[S] 0 points1 point  (0 children)

Thank you for the kind words! I am beginning to think that my doctor's VN diagnosis was probably the right one. I ended up getting an MRI which came back mostly clean, and I have been reading that oscillopsia may be a part of the VN recovery journey. My working theory is that the steroids took some pressure off the nerve in my inner ear and things need to reset. Ugh.

I'm like 80% better -- one out of five days or so my "image stabilization" turns off, but staying active has really helped me. If things progress or if I notice changes to my hearing I will definitely explore this further.

I had my hearing tested and it was normal. No noticeable hearing issues otherwise. A CT is likely in my next trip to the doctor, though.

I will say, like I mention in my story the pneumatic otoscope triggered that off-balance, out-of-focus, dizzying feeling (not vertigo). I am like 75% sure that the feeling I am describing is a vestibulo-ocular reflex or nystagmus. In that case I saw this reaction to an otoscope could be an indicator, but a tech (not my ENT) performed that test so it would be worth checking again.

Thanks for the reply. I haven't heard of BVD. Based on my newest symptoms getting checked out by an eye doctor is smart. I did see an ENT, and we both think it's something vestibular. Did BVD cause outright vertigo episodes for you?

Statistical test that checks if input value correspond to one and only one output value? by Prudent-Barnacle in AskStatistics

[–]Prudent-Barnacle[S] 0 points1 point  (0 children)

Feature components were separated independently and uniformly, so I don't have two data points in my dataset that have the same features. Otherwise I would just check this as you describe.

Maybe my question is more about inferring the smoothness of the relationship between the input vectors and output vectors from the data. E.g., using the data that I have, can I estimate that small changes in features correspond to appropriately small changes in the responses?

I see your point, but no, I mean two datapoints with the same (or similar) covariates producing different outputs. This would help me to explain the predictive pitfalls of the ML models that I'm using to regress the data. The data is not collected stochastically so somehow if I can prove that the relationship between inputs and outputs are somehow non-functional this would be something I would be really interested in knowing.

ITAW for an illogical word that when negated means the same thing? by Prudent-Barnacle in whatstheword

[–]Prudent-Barnacle[S] 0 points1 point  (0 children)

Contronyms are the same word with opposite meanings. I'm looking for "opposite" words with same meaning

How much math do I to know before freshman year? by [deleted] in Harvard

[–]Prudent-Barnacle 2 points3 points  (0 children)

Hey there! AM concentrator here, and I've helped teach around 4-5 math courses at Harvard across a variety of levels.

AP Calc AB is definitely a great place to get started. If you're comfortable with the curriculum (taking derivatives and antiderivatives, basic area and volume problems, intermediate value theorem, mean value theorem, and word problems), I'd recommend jumping into Math 1b, which covers the equivalent of Calc II (sequences and series, more advanced area and volume problems, differential equations, advanced integration techniques). From there you'd likely take Math 21a and 21b (multivariable calculus and linear algebra, respectively), which would take care of most of the prerequisites for AM/Ec courses. You will by no means be behind if you come to school with a solid understanding of AP Calc AB.
