Predict Trip time duration from Pick up and Drop off Latitude and Longitude using Azure ML Studio

I'm using Microsoft
Azure Machine Learning Studio to create an experiment for predicting
time duration of a trip by using
a data set containing previous records of the trip time along with latitude and longitude of the pick up and drop off location.
Can anyone help me out with whatregression model (or
R-Script optional) should I use to train my model?

Hi,
Are you training with raw latitude/longitude? If so, you should try clustering the start/end points into groups. An easy way to do this is to take a decimal or two off the values. Otherwise, the algorithm is seeing
many, many, unique pairs which may degrade the model performance.
You will probably also want to use the
Learning with Counts modules to summarize that lat/lon data because even with clustering, the features will still have high dimensionality. Here's some info on learning with counts:

Also, we did some experiments on similar data so if you want to read more about that see:

  • HT201250 Can i store my files on time capsule from my ipad, and copy them back, without using itunes to sync the tablet?

    Can i store my files on time capsule from my ipad, and copy them back, without using itunes to sync the tablet? i want to buy an iPad Air and to forget my laptop and i think that even the 128 gb wont be enough some times. I am wandering if time capsule can be used as external hdd and to connect on it via wifi ...

    No. You cannot access your Time Capsule directly from an iOS device. The only way to back up an iOS device is to a computer through iTunes or to iCloud, though in some cases you can open and save files via another cloud-based service such as Dropbox.

  • How to remove the time slider from my project and keep only buttons

    How to remove the time slider from my project and keep only buttons to interact with my project .

    If I understand you correctly, go to the skin editor (Project, Skin Editor in Captivate 4), select the Playback Control tab, uncheck the Progressbar check box.  Leave checked the buttons for play/pause, rewind, forward, back, etc.
    I hope this helps.

  • It says iCal will default events with no end time to one hour..and mine used to..but since I upgraded to Lion it doesn't.  Any suggestions as to how I can get it to default events to one hour?

    My iCal used to default to one hour when I posted an event with a start time and no end time.  The user guide says it will default to one hour.  Since I started using OS Lion, my calendar doesn't do that.  Can anyone suggest a way for me to get the calendar to default to one hour again?  Thanks.

    Dana,
    Here are some iCal data entry tips from iCal Help:
    Enter a name, date, and time duration for the event, and then press Return.
    For example, you can enter “Super Bowl Party Feb 5,” “Movie with Rebecca on Friday at 7pm,” “Soccer Game on Saturday from 11am-1pm,” or “Breakfast with Jon,” and then press Return.
    If you don’t enter a time duration for the event, iCal sets the event’s duration to 1 hour.
    If you don’t enter any time information for the event, iCal makes the event an all-day event.
    If you enter “breakfast” or “morning,” iCal sets the event to start at 9 a.m.
    If you enter “lunch “ or “noon,” iCal sets the event to start at 12 p.m.
    If you enter “dinner” or “night,” iCal sets the event to start at 8 p.m.

  • Can time capsule be connected wirelessly and still use ethernet ports for other devices?

    can time capsule be connected wirelessly and still use ethernet ports for other devices? we have it connected wirelessly but devices connected to the ethernet ports are not working.

    Not as an additional router.. the TC will be plugged into the main router via ethernet (or ethernet equivalent)..
    Then the TC is setup in bridge mode. It will simply act as a Switch and HDD.
    The wireless can be setup in a number of ways.
    From your convenience point of view use it in roaming network mode..
    you simply give the TC the same Wireless Name as the existing routers SSID.
    Same security setting and password. WPA2 Personal = WPA2 AES which is the best.
    But they both use different wireless channels.. normally if you leave the TC on auto it will work fine, but I prefer to control the network.. so set the main router to say 1 and the TC to 11.
    You can also use a completely different wireless name etc.. that is up to you. It is still a single flat network and the only thing that is important is only having one router.

  • I want to remove my credit card from my account and only use gift cards for purchases. How can I delete my card number?

    I want to delete my credit card from my account and only use gift cards.  How can I delete my card number?

    You'll want to get in touch with ITunes support for this. Normally when you start an account with the CC you can't remove it yourself. But by contacting iTunes they can get that taken off for you.
    Use this link to get in touch with the iTunes advisors

    dear sir i made a video to my brother in his wedding day from his photo and i use a song i buy it from itunes as a soundtruk , can i use this video in the facebook

    No. Tracks you purchase from the iTunes Store are for your personal use only and cannot be posted, either separately or as part of a video or slide show, on any public web site or otherwise distributed to others in any way. You can't even legally give that video to your brother.

  • Can I logoff from my iTunes and login using my family share id, download the apps that I want that waves to apps previously purchased before I linked family sharing

    Can I logoff from my iTunes and login using my family share id, download the apps that I want that were previously purchased before I linked family sharing with my unique Apple id, logout, and log back in with my Apple ID to have access to the apps?

    If you transfer any iTunes content to the iPhone from an iTunes library on another computer, all iTunes content on the iPhone will be erased first with a warning message provided indicating this beforehand.
    Authorize the different computer with your Apple ID with iTunes. With your iPhone connected and without syncing, right click on the iPhone under Devices in the iTunes source list and at the menu window that appears, select Transfer Purchases. This will transfer all apps on your iPhone to the iTunes library.

  • With Adobe Premier Elements 13 can I add my own audio tracks by pulling music from my files and by using my UBS microphone?

    With Adobe Premier Elements 13 can I add my own audio tracks by pulling music from my files and by using my USB microphone?

    larryh
    Please remind us on what computer operating system your Premiere Elements 13 is running
    Using your own music.....
    Yes, with important but.....
    Details
    If your music is from iTunes, more than likely you will get some sort of error message from the program when you try to import the iTunes music into Premiere Elements (most versions including 13). In that case, please convert the iTunes music to the wav version in iTunes using the following iTunes instructions.
    iTunes: How to convert a song to a different file format - Apple Support
    If you are getting program error message using Premiere Elements 13 Add Media/Files and Folder with other than iTunes music, please give the source and properties of that music.
    Using USB Microphone....Not recommended by Adobe....See Adobe ReMe
    Details
    As for Premiere Elements narration clips using the its Narration Tool
    1. Adobe documentation indicates the USB microphone do not work in Premiere Elements and suggest the use of microphones that connect to the computer via computer jack.
    But, there are some scattered cases where the user has found a USB microphone that has worked for him or her.
    2. Be sure to check Edit Menu/Preferences/Audio Hardware ASIO settings to assure that Input and Output are enabled.
    3. There have been reports (Premiere Elements several versions) where addition of narration using the Narration Tool results in loss of pre-existing
    sound on numbered audio track clips and soundtrack.
    ATR Premiere Elements Troubleshooting: PE12: Audio Losses After Narration Addition
    4. In my particular Premiere Elements 13 on Windows 8.1 64 bit, I have found that I need to set the Mic Sensitivity all the way to the left to avoid
    serious audio distortion.
    I have tried to give you an overview to avoid surprises if you have not used the features that you pointed to in your thread question. Please let me know if you need further information.
    Thank you.

  • I have an iphone 3gs version 4.1 ! i got it from ebay usa and i use it in cyprus.if i update it will it lock?

    i have an iphone 3gs version 4.1 ! i got it from ebay usa and i use it in cyprus.if i update it will it lock?

    All US sold iPhones are carrier locked to AT&T.
    Neither AT&T or Apple will unlock them under any conditions.
    If the device is unlocked, it has been un-officially unlocked.
    Updated the device will almost certainly relock it to AT&T.
    Save yourself some hassle, either return it to the seller or re-sell it online.  Then purchase an iPhone intended for use in your country.

  • How can I store and use my library solely from my iPad and not use my Mac

    I have an iPad and I'm currently using iTunes Imatch to sync my music from my Mac to my iPhone and iPad. But I will no longer have access to my Mac. How can I transfer all music to just my iPad and access all music to be used from the iPad and iPhone

    Again, i-devices are not realy intended to be used as stand-alone devices, certainly not when you're talking about extended options.  We do use an iPhone without a computer but it has never been synced in the 2 years we have had it and has no media on it other than what is produced by the camera.
    You talk about downloading new music, but without the Mac you pretty much won't be able to do that anyway.  You can purchase music from the iTunes Store and then it is, or course, in iCloud and can be downloaded to other devices too from there (with small limitations into which I won't go).
