Machine Learning
Topics from Stanford's Machine Learing class:
Supervised learnings.
In supervised learning, one has a set of data with features and labels.
Linear Regression – one/multiple variables
Gradient Descent - a general algorithm for minimizing a function
Logistic Regression – This is useful when predicting classification type results. For example, are you looking for a yes or no result. Does the patient have cancer? Will the customer buy my new product? It can also be helpful for more than 2 results. What color will a person choose (red, blue, green, silver)?
Neural Networks – A learning algorithm that is modeled after the brain. Think of neurons.
Unsupervised Learning
In unsupervised learning, one has a set of data with no features and labels. Can some structure be found for the data?
Clustering – The most popular technique is K-means.
PCA (Principal Components Analysis) – speed up a learning algorithm
Anomaly Detection
This section covers methods to determine if data is bad. Bad data is considered an anomaly.
Recommender Systems
Like the name says, recommender systems are used to make recommendations. Companies like Netflix use recommender systems to recommend new movies to customers. LinkedIn also recommends people to connect with. This is a fairly hot topic in the tech world right now.
Content Based(Features)
Modified Linear Regression
Non-content Based(No Features)
Collaborative Filtering
Matrix Factorization

Tweet Street View
Drive the streets and read the tweets. Our mashup for Google Street View and Twitter – Tweet Street View has been updated.
Drive or walk with Street View and see tweets nearby. You can see Street View and either an appropriate map or a list of nearby messages from Twitter. So, you can read the latest real-time news for the places you are in with Street View.
By default mashup shows some predefined sites and you can see your own location. Just pass your latitude/longitude pair to the URL. Parameters are
lat - latitude
lng - longitude
So, it looks like this:
http://tsv.linkstore.ru?lat=YOUR_LATITUDE&lng=YOUR_LONGITUDE
E.g. drive through El Camino Real
Technically it is Google Street View (via Gmaps utils) + Twitter search + several mashups from our directory.

Places and customized check-ins for Facebook
You are welcome to check out a new version of our mashup Places from Facebook.
Lets you search for places, show them on the map, copy locations to mobile, see friends activity, check-in anywhere as well as prepare mobile web pages for customized check-ins.
You can directly pass the following parameters to the basic URL:
lat - latitude
lng - longitude
q - query for search
For example, Facebook in London
For customized check-in place owner (or advertising/marketing agency, for example) can define all the aspects of check-in - data to be posted on user's wall, data to be returned as a confirmation, Google Analytics code for stats monitoring etc. This version provides own analytics for check-ins too. And of course you still can use Facebook’s dashboard for places pages - mashup creates standard check-ins for Facebook.
In other words – any small business can create public (or private) "Foursquare-like" system for own visitors. Using all the power of Facebook’s user base.
P.S. See also QRpon – customized check-ins for Facebook
P.P.S. and here you can see Places from Google for the same area.

Big data
"Big data is data that exceeds the processing capacity of conventional database systems. The data is too big, moves too fast, or doesn't fit the strictures of your database architectures. To gain value from this data, you must choose an alternative way to process it." - a good introduction into big data

lat – latitude
lng – longitude
For example, buying and selling in:
London
Palo-Alto
Mashup lets you see "buy-and-sell" tweets with photos. Also you can directly pass your search string to the basic URL. Parameter's name is q. For example: iPad

About Facebook fans
Free WiFi for check-in. Looks like this, is not it?
"Why doesn’t everyone do this? It is clearly a better return than some CPM ad that users are dying to get away from… it’s relevant, not spammy and surprisingly welcome." - sure :)

Places from tweets
Yet another our mashup has been updated - Location from Twitter.
Usually, the bundle Twitter + Maps always means mapping twits and show them on the map. Yes, we have such mashups too (see for example, Photo map или Local twitter). But here everything is vice versa. It is just a reverse task.
Suppose you are reading a great geo-located twit. Just a status associated with some place (location). In Twitter's web client you can see that place and an appropriate icon just below the message. How to get that place info and save/bookmark it on your phone? It is what our mashup - Places from Twitter is for.
It is very similar to our Location bookmark, but with Twitter status instead of address. Mashup Locations from Twitter also creates QR code for mobile map. And mobile map describes a place from Twitter. And here we are using Geo Messages again.
The usage is simple. Just open in Twitter’s web interface any geo-enabled twit and copy its URL to mashup’s form. Also you can save the following link Place from Twitter in your bookmarks and simply select that bookmark on any opened page with geo-enabled twit (it is so called bookmarklet).
And of course, any QR code created with this mashup could be placed anywhere – on your site/blog, Facebook wall etc. You can even print it and place on the physical wall. Mashup provides HTML code you need for embedding QR code image.
