Cum s-a \u00eent\u00e2mplat asta?<\/h1>\n

\nDup\u0103 un parcurs anevoios de la absolvent al facult\u0103\u021bii de radiotehnic\u0103, prin angajat al unei institu\u021bii \u0219tiin\u021bifice de stat, profesor al unui curs special la alma mater iubit\u0103, am ajuns \u00een cele din urm\u0103 un angajat respectat \u00een departamentul R&D al unui start-up foarte fain \u00een domeniul realit\u0103\u021bii augmentate. Banuba<\/a><\/noindex>.<\/p>\n

Companie tare, sarcini interesante, un program \u00eenc\u0103rcat, condi\u021bii grozave \u0219i salarii\u2026 dar, dup\u0103 ce am lucrat \u00een institut de cercetare, unde stai \u00een laborator cu al\u021bi oameni cu o educa\u021bie matematic\u0103 similar\u0103 care \u00ee\u021bi \u00een\u021beleg fluxul de con\u0219tiin\u021b\u0103 dintr-o singur\u0103 propozi\u021bie, a fost dificil s\u0103 comunic cu cei care nu f\u0103ceau matematic\u0103. Le spun lucruri care par simple \u0219i evidente, precum \u201eai verificat datele pentru homoscedasticitate?\u201d, iar ei m\u0103 roag\u0103 s\u0103 nu m\u0103 exprim a\u0219a \u00een fa\u021ba fetelor. De asemenea, trecutul meu de profesor m-a urm\u0103rit\u2026 A\u0219a c\u0103 am devenit un participant activ \u00een \u00eemp\u0103rt\u0103\u0219irea de cuno\u0219tin\u021be \u00een cadrul companiei. \u0218i, dintr-un anumit moment, am \u00eenceput chiar s\u0103 conduc un mic grup de matematic\u0103.<\/a><\/noindex> \u00cen prezent, b\u0103ie\u021bii deja \u0219i-au \"finalizat studiile\".<\/p>\n

De\u0219i nu au devenit \u00eenc\u0103 data scientists \u00een R&D, le-a devenit mult mai u\u0219or s\u0103 \u00een\u021beleag\u0103 despre ce vorbesc matematicienii \u00een limbajul lor. Dac\u0103 doresc, vor putea continua s\u0103 studieze pe cont propriu sau prin cursuri video. Obiectivul principal, care, din punctul meu de vedere, a fost atins cu succes \u00een cursurile noastre, este de a ar\u0103ta oamenilor c\u0103 matematica nu este at\u00e2t de complicat\u0103 \u0219i \u00eenfrico\u0219\u0103toare cum pare la prima vedere. Trebuie doar s\u0103 te obi\u0219nuie\u0219ti cu un mod specific de g\u00e2ndire: s\u0103 desfaci lan\u021burile ra\u021bionamentelor logice. <\/p>\n

\nAu fost comentarii, au fost \u00eentreb\u0103ri\u2026 S-a dovedit c\u0103 oamenilor le este interesant\u0103 matematica. S-a dovedit c\u0103 oamenii ar dori s\u0103 \u00eenve\u021be (\u00een majoritatea cazurilor, cred c\u0103 ar dori s\u0103 repete ceea ce au \u00eenv\u0103\u021bat anterior:).<\/p>\n

Despre ce este canalul?<\/h1>\n

\nPe canal sunt conferin\u021be video scurte (de p\u00e2n\u0103 la 20 de minute).
\nVor fi \u00een total 3 mari sec\u021biuni: A) matematic\u0103, B) procesarea \u0219i analiza datelor (aici va fi \u0219i despre procesarea imaginilor) \u0219i C) \u00eenv\u0103\u021barea automat\u0103. <\/p>\n

Sec\u021biunile B) \u0219i C) vor fi completate cu lec\u021bii despre implementarea algoritmilor studia\u021bi \u00een Python, folosind NumPy, ScikitLearn, Pandas etc.<\/p>\n

Sec\u021biunea matematic\u0103 va include \u00eentreaga baz\u0103 matematic\u0103 necesar\u0103 pentru sec\u021biunile B) \u0219i C), \u00eencep\u00e2nd chiar de la \u00eenceput. Deoarece afirm accesibilitatea matematicii pentru to\u021bi doritorii, vom \u00eencepe cu o scurt\u0103 repeti\u021bie a celor mai elementare concepte.<\/p>\n

\u00cen momentul de fa\u021b\u0103 (5 s\u0103pt\u0103m\u00e2ni de la start) s-a \u00eencheiat primul bloc 'Introducere \u00een matematic\u0103'. \u00cen acest bloc, am repetat pe scurt cursul \u0219colar de aritmetic\u0103, am reamintit toate propriet\u0103\u021bile exponentelor, MMC, MCD, frac\u021bii, formulele de multiplicare scurt\u0103 etc. <\/p>\n

A \u00eenceput al doilea bloc, dedicat mul\u021bimilor \u0219i opera\u021biunilor logice. Matematica nu face parte din programa \u0219colar\u0103, dar nu este mai dificil\u0103!<\/p>\n

\u0218i va urma \u00eenc\u0103 multe lucruri interesante: repetarea programului \u0219colar de algebr\u0103 \u0219i geometrie, trigonometrie, tranzi\u021bie lin\u0103 \u00een planul complex, deriv\u0103 \u0219i integrale, algebra liniar\u0103, analiza spectral\u0103 a ecua\u021biilor diferen\u021biale, geometria analitic\u0103, teoria probabilit\u0103\u021bilor\u2026<\/p>\n
