`
` 5 EXAMINATION
`
` 6 BY MR. NOTO:
`
` 7
`
`Q.
`
`My name is Aldo Noto. We just
`
` 8 introduced each other. May I have your full name
`
` 9 for the record?
`

`
`Q.
`
`A.
`
`Q.
`
`My name is Tanzeem Choudhury.
`
`And what county do you live in?
`
`Monroe County.
`
`Have you ever been deposed before?
`
`No.
`
`No. Okay. Other than the declaration
`
` 16 that you provided in this case, have you ever
`
` 17 provided a declaration before?
`
` 18
`
` 19
`
`A.
`
`Q.
`
`I have.
`
`Can you tell me what cases you've
`
` 20 provided declarations in?
`
` 21
`
`A.
`
`I will have to look through my e-mails
`
` 22 and previous declarations to pull up that list.
`
` 23
`
`Q.
`
`Okay. Have you ever testified in court
`
` 24 before?

`
` 1
`
`Q.
`
`Have not. Okay. So just a little bit
`
` 2 of background. I'll be asking questions. You'll
`
` 3 be answering questions. If you don't understand my
`
` 4 question, we can have the court reporter repeat it
`
` 5 or I can repeat it for you. If you need a break,
`
` 6 just let us know, we'll take a break. We can't
`
` 7 speak over each other because the court reporter is
`
` 8 trying to record. So try to avoid doing that as
`
` 9 much as possible.
`
` 10
`
` 11
`
`A.
`
`Q.
`
`(Nodding affirmatively).
`
`And during the day, during the
`
` 12 deposition, while you're allowed to speak with your
`
` 13 lawyer on breaks, you can't discuss the testimony
`
` 14 that's being provided.

` 19
`
` 20
`
` 21
`
` 22
`
`A.
`
`(Nodding affirmatively).
`
`MR. BATTS: I would note that the court
`
`reporter has already noted that you've been
`
`nodding affirmatively. Let's try to have
`
`verbal responses instead of nonverbal
`
`responses. Okay?
`
`THE WITNESS: Understood.
`
`MR. NOTO: Thank you.
`
` 23 BY MR. NOTO:
`
` 24
`
`Q.
`
`What have you reviewed in preparation

`
` 3 folders to give a complete list.
`
` 4
`
`Q.
`
`Okay. Let me ask you a different line
`
` 5 of questioning first, ma'am. Are you on any
`
` 6 medication that would prevent you from testifying
`
` 7 truthfully today?
`
` 8
`
` 9
`
`A.
`
`Q.
`
`I take hypertension medication.
`
`Will that prevent you from testifying
`
` 10 today -- testifying truthfully today?
`
` 11
`
`A.
`
`As far as I understand and my doctors
`
` 12 understand, no.
`
` 13
`
`Q.
`
`Okay. Is there anything else that would
`
` 14 prevent you from testifying truthfully today?
`

`
`Q.
`
`No.
`
`Okay. Have you ever been arrested?
`

`
`Have you ever been charged with a crime?

`No.
`
`How long did you -- how many hours did
`
` 21 you take in preparing for this deposition?
`
` 22
`
`A.
`
`Specifically just for the deposition or
`
` 23 generating my expert witness?
`
` 24

`Q.
`
`No. Specifically now in preparation for
`
` 25 the deposition today.

`
` 13 where did you review the materials in preparation
`
` 14 for the deposition today?
`
` 15
`
`A.

`I reviewed the materials at home. I
`
` 16 reviewed materials in New York City when I flew in
`
` 17 for the deposition.
`
` 18
`
`Q.
`
`Okay. How many days did you spend in

`
`Q.
`
`In May of 1997, after graduating from
`
` 5 the University of Rochester, what did you do next?
`
` 6
`
`A.
`
`I went to Bangladesh to visit my parents
`
` 7 before starting grad school.
`
` 8
`
`Q.
`
`And how long did you stay in Bangladesh
`
` 9 during 1997?
`
` 10
`
` 11
`
`A.
`
`Q.
`
`I returned in August 1997.
`
`So it's fair to say that from May of
`
` 12 1997 to August of 1997, you were in Bangladesh?
`
` 13
`
`A.
`
`Yes. But I would have to go back there
`
` 14 to see if I took any family trips or take any trips
`
` 15 outside, but I did go to Bangladesh.
`
` 16
`
`Q.
`
`Okay. During the period from May of
`
` 17 1997 to August of 1997, did you work or study?
`
` 18
`
`A.
`
`It is 21 years ago, so it's hard to
`
` 19 recall if I did internship or not. I do not
`
` 20 recall. But I cannot conclusively confirm. And I
`
` 21 think a question about study, are you asking was I
`
` 22 -- if I was enrolled in a degree program.
`
` 23
`
`Q.
`
`Yes. Let's start with that. Were you

`
`I did.
`

`
`I cannot give you the exact title. It
`

`
` 8
`
`Q.
`
`And when did you finish the thesis on

`

`
` 15 that time period.
`

`
`Q.
`
`I'm just asking in general if there's
`
` 17 anything in here that would help us understand what
`
` 18 you were doing from August of 1997 until October of
`
` 19 1998. And if there isn't, that's fine.
`

`
`A.
`
`August of 1997 to October 1998. Well, I
`
` 21 was a research assistant at Media Lab from
`
` 22 September 1997 to August of 2003. So I continued
`
` 23 as a research assistant.
`

`

`
`A.
`
`It was about tracking facial features
`

`
` 17
`
`Q.
`
`Did it have anything to do with facial
`
` 18 recognition?
`

`
`A.
`
`Are you asking whether it did person
`

`
`Yes. Let's start there. Did it do

`
`Q.
`
`A.
`
`Q.
`
`A.
`
`Yes.
`
`Whether they are the same thing?
`
`Yes.
`
`Typically, in the field, there is a
`
` 15 distinction.
`
` 16
`
` 17
`
`Q.
`
`A.
`
`And what would that distinction be?
`
`Face recognition is recognizing a human
`
` 18 face. Person identification is identifying who the
`
` 19 face belongs to.
`
` 20
`
` 21
`
`Q.
`
`Very well.
`
`So your undergraduate thesis, "Face and
`
` 22 Facial Feature Extraction and Tracking in Video
`
` 23 Sequences," did that thesis involve either facial
`
` 24 recognition or person identification?
`
` 25
`
`A.
`
`I did that research more than 21 years

`
` 8
`
`Q.
`

`
`Sure. Why don't we do that.
`
`Actually, let me refer you to paragraph
`
` 9 48 of your declaration, which is Exhibit 1005, at

`
`Q.
`
`The question is: Did you publish a
`
` 13 paper in 1998 entitled, "Multi-Modal Person
`
` 14 Recognition using Unconstrained Audio and Video"?
`
` 15
`
`A.
`
`I did work on a research, Multi-Modal
`
` 16 Person Recognition Using Unconstrained Audio and
`
` 17 Video. I wrote a paper about it that was submitted
`
` 18 at conference, and then it was accepted and it was
`
` 19 published. The specific date of when the paper was
`
` 20 written, when it was accepted, and when it was
`
` 21 published is something that I don't recall.
`
` 22
`
`Q.
`
`Okay. It was sometime during the year
`

`
`Can you tell us the paper that you

`
` 16 that was published?
`
` 17
`
`A.
`
`So I believe that I am referring to the

`

`
` 20 and submitted in 1998.

`Q.
`
` 11 pictures?
`
`Video.
`
`I'm sorry. Video streaming.
`
`It was on video.
`
`Why was video used rather than still
`
` 12
`
`A.
`
`Video is a sequence of still pictures.
`
` 13 Video often can be present in a lot of situations
`
` 14 where facial recognition is needed.
`
` 15
`
`Q.
`
`And for the facial recognition, did your
`
` 16 research -- study the facial features on still
`
` 17 pictures?
`
` 18
`
` 19
`
`A.
`
`Q.
`
`Yes.
`
`Prior to October of 1998, let's say
`
` 20 prior to October 28th of 1998, did you do any
`
` 21 research or development or manufacturing work of
`
` 22 any pedometers?
`
` 23
`
`A.
`
`I did not do any manufacturing work on
`
` 24 pedometers. I was in a graduate program where

`
`Q.
`
`What was the name of the graduate
`
` 6 program that had an emphasis on wearables?
`

`V-I-S-M-O-D.
`
`And do you know what that acronym stands
`
`Vision and Modelling.
`
`Did that group do any research or
`
` 15 development of a pedometer?
`
` 16
`
`A.
`
`The group included the MIT wearables
`
` 17 team, which invented and worked on and researched
`
` 18 on an array of wearable devices.
`
` 19
`
`Q.
`
`When did you first join the VISMOD
`
` 20 group?
`
` 21
`
`A.
`
`When I started my master's degree at MIT
`
` 22 in 1997, the fall of 1997.
`
` 23
`
`Q.
`
`What work did you do at the VISMOD group
`

`
` 2 your knowledge in that field while executing on
`
` 3 specific research projects. I was doing all of
`

`
`Q.
`
`What specific research projects were you
`

`
` 10
`
`Q.
`
`Did you work on development or research
`
` 11 regarding wearable motion detector devices prior to
`
` 12 October 28, 1998?
`
` 13
`
`A.
`
`I cannot recall specifically, so I
`
` 14 cannot confirm or deny. At some point during my
`
` 15 graduate degree, I worked on wearables.
`
` 16
`
`Q.
`
`Did the wearables that you work on
`
` 17 during sometime -- during your graduate program
`
` 18 involve measuring acceleration of body parts?
`
` 19
`
` 20
`
`A.
`
`Q.
`
`Yes.
`
`When did you do that work in measuring
`
` 21 acceleration of body parts?

`
`A.
`
`Q.
`
`I cannot recall specific dates.
`

`Yes.
`
`Yes.
`
`What were you measuring with -- let's
`

`
`A.
`
`It's an integrated circuit for measuring
`
` 10 -- making measurements.
`
` 11
`
`Q.
`
`What kind of measurements was your
`

`
`A.
`
`Q.
`
`I cannot recall.
`
`Prior to October 28, 1998, did you

`
`MR. BATTS: Objection. Form.
`

` 19 mean by exercise science field?
`
` 20 BY MR. NOTO:
`
` 21
`
`Q.
`
`In your expert report, Exhibit 1005, you
`
` 22 use the term "exercise science."

`
`Can you tell me what that term means?
`
`A.

`
` 10 people.
`
` 11
`
`Q.
`
`So if I understand you correctly, your
`
` 12 understanding of the term "exercise science" based
`
` 13 on your last answer is technology solutions that
`
` 14 could be applied in tracking a measurement of
`
` 15 physical activity of a person?
