For the first time, scientists from the Shanghai Jiao Tong University have developed a new program to detect criminality just by analyzing facial features. Through supervise machine learning, they built four classifiers using facial images of 1856 real persons. Nearly half of them were criminals. The four classifiers are the logistic regression, KNN, SVM, CNN. All four classifiers perform consistently and generate proof for the validity of automated face-induced inference on criminality.
The criminal and non-criminal face images occupy two different manifolds. It consists of both criminal and non-criminal faces that are concentric. It means normal people have a greater degree of similarity as compared to criminal people faces.
Katyanna Quach, said, “It is true that machines don’t have emotions or conscience to consider as subjective. But that doesn’t mean data can’t get biased. The researchers maintained the data sets for the race, gender, age and facial expressions.”
Researchers said, “This is the first study that automates face-induced inference on criminality. It is free of any biases of subjective judgments of human observers. By extensive experiments and vigorous cross validations, we have demonstrated that via supervised machine learning, data-driven face classifiers are able to make reliable inference on criminality.
Two Chinese researchers, Xiaolin Wu and Xi Zhang are quite serious about their work. They fed into a machine learning algorithm facial images of 1,856 people. For this, they used standard ID photographs (not mugshots) of Chinese males between the ages of 18 and 55. The men did not have facial hair. Additionally, they were tensed about the criminal face images in Sc are normal ID photos, not police mugshots. After that, they used 90 percent of these images to train a convolutional neural network to recognize the difference. They then tested the neural net on the remaining 10 percent of the images.
n go back, the classifiers executed very well and gave proof for the validity of automatic face-prompted inference on criminal activity.
In return, the classifiers performed very well and gave proof for the validity of automated face-induced inference on criminality.
According to MIT Technology Review’s discussion, the neural network could correctly identify criminals and noncriminals with an accuracy of 89.5 percent. Researchers found that criminals have 19.6 per cent smaller nose-mouth angle, a larger upper lip curvature at 23.4 percent, and a 5.6 percent shorter distance between the inner corners of the eyes.
Quach said, “researchers have found some discriminating structural features for predicting criminality. For example, lip curvature, eye inner corner distance, and the so-called nose-mouth angle.”
“By looking at their findings, it’s bad news for those who have smaller mouths, curvier upper lips, and close-set eyes, as you look more like a crook, apparently. On average, criminals have a 19.6 percent smaller nose-mouth angle, a larger upper lip curvature at 23.4 percent, and a 5.6 percent shorter distance between the inner corners of the eyes.”
There is no such software created in a vacuum. People designed software. People who set out to infer criminality from facial features are not free from inherent bias.
By looking forward, MIT Technology review said, “Of course, this work needs to set on a much stronger foot. It needs to be reproduced with different ages, sexes, ethnicities, and so on. And on much larger data sets. All this heralds a new era of ‘anthropometry, criminal or otherwise,’ and there is room for more research as machines become more capable.”
TStv to Encrypt it’s Channels, roll out 62 Premium Entertainment Channels
TStv has announced that all of it’s Television channels will be encrypted. This means that the channels on TSTV will no longer be Free-to-air (FTA). The service provider also announced that it will include 62 premium Entertainment channels in it’s collection.
TStv channels will be encrypted starting from 11:50 on November 27th. Also, the premium entertainment channels will be included to the service on 28th November. Prior to the update, viewers will have to pick up a TStv Jolly Decoder at a dealer outlet.
Owners of the Sassy Decoder are advised to visit any nearest dealer to get the decoder fully activated.
TStv currently has over 50 plus channels which in addy is the 16 premium entertainment channels coming soon.
TStv Africa is a owned Nigerian innovative Pay TV Operator that offer Pay As You View (PAYV) subscription, pause subscription, complimentary internet service and video call.
TStv sometime went out of the market due to the challenges the company faced even to the “Satellite Providers”. The good news is that they began full operation on 20th August after NigComSat offered them 5 units of 35.5MHz transponders through a collaboration with Intertel, Federal Ministry of Communications and Nigcomsat.
MTN APN Configuration That Works – Mobile and Modem
MTN APN is what is required to enable internet connection on your phone. APN is an acronym for Access Point Name. Access Point Name is typically the name of the gateway connecting your internet enabled device to the web through an internet service provider, such as MTN.
Most often we run into the problem of missing APN configuration and can’t surf the web with our phone or modem. If you have your APN configured before now and you still cannot browse, make the listed below are in order.
- Data subscription balance
- Data monitor app threshold
- Other phones of same network can browse. Your inability to browse could be a general problem from the service provider at the moment.
- Network signal reception
In Nigeria you can fall into the hands of the wrong people, who will charge you high amount of money in the name of configuring your phone for browsing.
To get the configuration pushed automatically to your phone by MTN.
Send as a text message “Settings” to 3888. Without quotes.
If the above method fails to get you APN configuration, you can fall back to configuring it yourself which always works.
For Mobile phones, navigate to “mobile network” in settings through more connections option, and you should see APN configuration option there.
Note: If your device works just fine, you are advised not to go further. But if for a reason you deleted the pre-installed APN configuration and you want to get it back. You’re welcome. The configurations work for 2G, 3G and 4G network type.
MTN APN settings for smartphones (iOS and Android)
Note: For MTN 4G MiFi modems, the above configuration works for such devices.
MTN APN settings for modems (U.S.B stick modems)
Access Point Name is unique to every service provider and can come pre-configured in SIM cards. When you slot in a new SIM card into a phone, it goes through it’s initiation to the service provider’s system. The service provider can then push necessary configurations to the device. Devices with MTN SIM card making an internet connection must be configured with an APN to present to MTN.
MTN will then examine this APN to determine what type of connection should be created, for example: which IP addresses should be assigned to the wireless device, which security methods should be used, etc. All of which is done in a second by a programmed system.
#ReallyFreeData, Airtel is dashing free data weekly on Recharge Plus
Airtel NG is currently giving out free 250mb data to its subscribers so long as you keep recharging your line. The good news is that you get 250Mb every week, once you meet your recharging target. All Airtel users are qualified for this promo and it gets even better because you can use the data to access any website and content.
You can do the recharging through your bank and still get the reward. In total you enjoy 1GB monthly for simply topping up your airtime. You can use the airtime for regular uses, such as making calls and sending text, even subscribing to a regular data plan.
Speaking of the requirements to enjoy this offer, Airtel NG says you have to recharge your line consistently. Consistently in order to meet your weekly target.
How it Works:
- To get started, you have to first recharge your Airtel line.
- Check your weekly target by dialing *479# or check your recharge notifications.
- Recharge to hit your target
- Get rewarded with 250MB free.
- Dial *123# or *140#. to check balance
Hard to say:
The free data bonus is valid till Sunday 23.59pm every week. You don’t get the reward twice a week, so no need beating the target twice. Airtel didn’t say how long the offer lasts, but it looks like one that its not going over yet. You can’t roll over any unused data. That is to say, once it expires, it’s gone, no renewals.
