    Love your mother 

    Which topic/s in class made an impact to you? Why?

    Row Echelon Form and Reduced Row Echelon Form! Kasi pag sinasabi yung ~*ECHELON*~ sobrang sosyal pakinggan ang saya :^D Pero ok serious, may sense of achievement kapag nakapagtransform ng matrix to its RREF ❤ Yung effort sa pagsusulat at pagsosolve ang worth it haha!

    Plus Basis kasi medyo may bias(is) ako sa topic namin sa video tutorial ❤

    If you can summarize this course in one word or sentence, what would it be?

    “Challenging and at the same time, inspiring. Every meeting was an adventure.” — J.K. Rowling

    What would be your parting message to the class?

    Stay strong! And see you around 🙂

    Speech recognition with Fourier Transform 

    Speech recognition is the capability of an electronic device to understand spoken words. [1]  It can be seen in devices that have options for taking in voice commands such as Apple’s digital assistant, Siri, which is voice-controlled.

    Fourier transforms are used to process the digital signals and analyze the frequencies of the speech sounds. Its output can be used to identify phonetic features [2], which in turn could be compiled and compared with a “phonetic dictionary” to identify what has been said. [3]

    Aside from speech recognition, some have also made studies on emotional recognition (related to speech recognition) that also makes use of Fourier transforms. The transforms are analyzed for emotional classification, noting the stresses in the speech that could be used to model the emotional state of a person. [4]

    Left-Right Asymmetry 

    In my search for a possibly interesting application of symmetry in real-life, I came across a study on the symmetry of cells to help prevent birth defects [1]. What particularly caught my attention was the term “left-right asymmetry”. Basically, it is involved with the question of how our internal organs are positioned during embryonic development–how does the bilaterally symmetric embryo decide which is left/right and which is the correct side for an organ? [2]

    This is how I learned that 0.01% of our population has the condition called situs inversus totalis, where there is a mirror-image reversal in the positioning of the heart and other internal organs. [3] People with this condition don’t usually realize their unusual anatomy until they seek medical attention for other health problems not related to it. This usually causes confusion because many signs and symptoms appear on the reverse side. [4]

    This condition also happens to “mirror twins”–twins who have the same physical features but opposite, or “mirrored”. [5]

    It is usually complicated for people with situs inversus totalis to undergo heart transplants because the orientation of the heart is reversed and it is necessary to connect the blood vessels properly.

    The use of vectors in making Interactive Dynamic Videos 


    An Interactive Dynamic Video (IDV) is an imaging technique where you can “touch” and manipulate objects in a captured video recording [1]. They analyze the vibrations (or find what they call “vibration modes”) in the video in different frequencies to be able to predict how the object in the video would act/move in new situations (such as when poked or pushed). This technique involves acceleration, velocity, and displacement vectors (for modal analysis). [2]

    As a result, the videos can now be manipulated and be used to apply special effects.

    my pamily. homaygad. 

    Week 1: Introduce yourself

    What’s your name?

    I’m Michelle (wala akong official nickname pero may friends akong “Mich” yung tawag sakin; one time ito rin binigay kong nickname sa Fil40 class ko kasi akala ko required magbigay ng nickname tapos minsan ‘pag tinatawag ako ng prof ko ‘di ko narerecognize hahahahuhu *_* ito rin yung nickname na binigay sa ‘kin ng Kas2 prof ko kasi yung katabi ko ang nickname niya “Rich”, so magkatunog na kami. Wala lang, fun fact lang.)

    What were your thoughts when you enrolled in this course?

    Sinunod ko lang actually yung nasa curriculum so yung thoughts ko “dapat sundin ko yung curriculum huhu” 😀 Pero nakita ko naman na ito yung dapat na i-take na subject this sem so nag-enlist na ‘ko. Kasabay siya ng 180, tapos medyo looking forward ako na “sana si Sir Paul yung prof ko sa 180 kasi balita ko super fun daw yung mga nagiging class niya something something bagong dp tapos cool prof talaga masaya mag-aral” pero hindi natuloy. Pero ngayon happy na ‘ko ulit kasi sa 130 ko pala siya magiging prof. Nice!

    How comfortable are you with math?

    ‘Di ako sure kung comfortable ba ako with math, pero masasabi kong naa-appreciate ko na yung importance niya. Gets kong mahirap, pero natutuwa ako kapag naiisip kong merong steps para masolve yung problems and eventually makakakuha ka ng sagot. At least dito may sagot ka diba 😉

    What’s your dominant feeling right now?

    Happy (??), kasi nakakatuwa pala mag-type ng something na ganito (parang andami kong nasasabi compared sa kung paano ako magkwento irl–feeling ko mas madaldal talaga ako online). Tsaka medyo frustrated kasi madilim sa kwarto tapos narealize kong mas useful ata na may backlit keyboard sa ganitong situation pero kaya ko naman magtiis hehe mema.
