Please answer the questions below.
Question 1
1.
Which of the following is NOT a common symptom of ataxia?
Slurred speech
Difficulty with balance and coordination
Loss of vision
Tremors in the arms and legs
Question 2
2.
Why did the researchers of this paper use low-pass Chebishev filter for pre-processing?
To detect speech boundaries
To reduce all the noise above 1 kHz
To fine tune the threshold short-term energy
Question 3
3.
One of the features chosen was “spectral centroid”. What does that “spectral centroid” refer to?
The measure of spectral density.
The point where most of signal energy is contained.
The highest point in a frequency spectrum.
The range of frequencies covered by a signal.
Question 4
4.
Familiarize yourself with the speech of an ataxia person by listening to this 1 minute video.
I've watched it.
I didn't watch it.
Question 5
5.
Based on this video, how long did it take for Tallulah to be diagnosed with ataxia?
3 months
1 year
3 years
10 years
Question 6
6.
What was a limitation of this study?
Lack of variability of speech disturbance score
Small number of available subjects
Sometimes same clinical scores were used for different classes (e.g. healthy & low severity)
All of the above
Question 7
7.
Question 8
8.
Which was
not
one of the performance metrics used in the study?
Recall
R2 value
Question 9
9.
Which one of the options is wrong for the model described in the paper?
It can sometimes confuse low severity patients with high severity patients.
It can sometimes confuse healthy patients with low severity patients.
It can sometimes confuse healthy patients with high severity patients.
Question 10
10.
Listen this ataxia person's speech. Then compare your own speech with it. Write down 3 differences.
Why do we need a AI-powered method to diagnose ataxia?
For some patients, it takes so long to be diagnosed with traditional methods.
Expert listener might sometimes be wrong.
Every expert listener rates the parameters differently (rater variability).
For monitoring, patients need to go to clinic frequently, which is inconvenient.
In countries where free healthcare is not provided, frequent visits may be costly.
Ataxia can only be diagnosed with AI.
