Taw qhia

Niaj hnub no peb tau tsom mus rau tsim cov phiaj xwm kev kawm tshuab uas kwv yees qhov kub ntawm polynomial regression.

Kev kawm tshuab yog ib daim ntawv thov kev txawj ntse (AI) uas muab lub peev xwm los kawm tau zoo thiab txhim kho los ntawm kev paub yam tsis tau hais qhia meej meej. Machine kev kawm tsom mus rau kev txhim kho cov khoos phis tawj uas tuaj yeem nkag tau cov ntaub ntawv thiab siv nws kawm rau lawv tus kheej.

Polynomial Regression: -polynomial regression yog ib daim ntawv ntawm kev txheeb xyuas qhov rov qab uas qhov kev sib raug zoo ntawm kev ywj pheej sib txawv x thiab qhov sib txawv ntawm y yog ua qauv raws li nth degree polynomial hauv x.

Kev twv ua ntej: -Machine kev kawm yog txoj hauv kev los txheeb xyuas cov qauv hauv cov ntaub ntawv thiab siv lawv los txiav txim siab lossis txiav txim siab txiav txim siab. … Txog kev thim rov qab, koj yuav kawm paub ntsuas kev sib txheeb ntawm ob qhov sib txawv thiab suav kab zoo tshaj plaws rau kev kwv yees thaum kev sib raug zoo hauv qab yog kab.

2. Yam khoom siv hauv txoj haujlwm no

Cov khoom siv kho vajtse

1. Poj niam/Poj Niam Jumper Xov × (Raws li xav tau)
2. Breadboard (dav dav) × 1
3. LM35 sensor × 1
4. Bolt IoT Bolt WiFi Module × 1

Software apps thiab cov kev pabcuam online

1. Bolt IoT Bolt CloudBolt
2. IoT Android App

Kauj Ruam 1: Txuas LM35 Sensor mus rau Bolt

Kauj Ruam 1: Tuav lub ntsuas kom zoo ib yam uas koj tuaj yeem nyeem LM35 sau rau ntawm nws.

Kauj Ruam 2: Hauv txoj haujlwm no, txheeb xyuas tus pin ntawm lub sensor ua VCC, Cov Tawm Tawm thiab Gnd ntawm koj sab laug mus rau sab xis.

Hauv Cov Duab Khoos Phis Tawj, VCC txuas nrog xaim liab, Cov zis tawm tau txuas nrog xaim txiv kab ntxwv thiab Gnd txuas nrog xaim xim av.

Kauj Ruam 3: Siv tus txiv neej rau poj niam xaim txuas 3 tus pin ntawm LM35 mus rau Bolt Wifi Module raws li hauv qab no:

• VCC tus pin ntawm LM35 txuas rau 5v ntawm Bolt Wifi module.
• Cov zis tawm ntawm LM35 txuas rau A0 (Tus lej nkag tus lej sib piv) ntawm Bolt Wifi module.
• Gnd tus pin ntawm LM35 txuas rau Gnd.

Kauj Ruam 2: Kwv yees Qhov Kub

Kauj Ruam 1: Ua tib qho kev sib txuas zoo ib yam li 'Khoos phis tawj sib txuas rau qhov ntsuas kub ntsuas' lub vijtsam, hauv 'Kev cuam tshuam cuam tshuam lub ntsej muag hla VPS' cov ncauj lus ntawm 'Cloud, API thiab Alerts' module.

Kauj ruam 2: Fais fab lub Circuit Court thiab cia nws txuas rau Bolt Cloud. (Green LED ntawm Bolt yuav tsum nyob)

Kauj Ruam 3: Mus rau cloud.boltiot.com thiab tsim khoom tshiab. Thaum tsim cov khoom lag luam, xaiv cov khoom lag luam raws li Cov Ntaus Ntaus thiab hom sib cuam tshuam raws li GPIO. Tom qab tsim cov khoom, xaiv cov khoom tsim tam sim no thiab tom qab ntawd nyem rau ntawm lub cim teeb tsa.

Kauj Ruam 4: Hauv tab kho vajtse, xaiv lub pob xov tooj cua nyob ib sab ntawm A0 tus pin. Muab tus pin lub npe 'temp' thiab txuag kev teeb tsa siv lub cim 'Txuag'.

Kauj Ruam 5: Tsiv mus rau qhov chaws tab, muab cov khoom lag luam lub npe 'twv ua ntej', thiab xaiv tus lej hom li js.

Kauj Ruam 6: Sau cov cai hauv qab no txhawm rau txhawm rau ntsuas cov ntaub ntawv ntsuas kub thiab ua haujlwm cov lej sib thooj sib thooj algorithm ntawm cov ntaub ntawv, thiab txuag cov khoom teeb tsa.

setChartTitle ('PolynomialRegression');

setChartType ('kev twv ua ntej');

setAxisName ('time_stamp', 'temp');

mul (0.0977);

plotChart ('time_stamp', 'temp');

Kauj Ruam 7: Hauv cov khoom tab, xaiv cov khoom tsim thiab tom qab ntawd nyem rau ntawm lub cim txuas. Xaiv koj lub cuab yeej Bolt hauv qhov tshwm sim thiab tom qab ntawd nyem rau 'Ua tiav' khawm.

Kauj Ruam 8: Nyem rau 'teeb tsa kev teeb tsa' khawm thiab tom qab ntawv 'saib cov cuab yeej no' lub cim los saib nplooj ntawv uas koj tau tsim. Hauv qab no yog qhov screenshot ntawm qhov tso tawm zaum kawg.

Kauj Ruam 9: Tos txog 2 teev rau lub cuab yeej tso cov ntaub ntawv txaus taw tes rau Huab. Tom qab ntawd koj tuaj yeem nyem rau ntawm lub khawm twv kom pom cov cim twv ua ntej raws li polynomial regression algorithm.
