Visualizing High Dimensional Data (PCA, LLE, t-SNE)

Here is a Great talk about data visualization: Visualizing Data Using t-SNE - YouTube

Here is the PCA 2 dimension reduction of mnist data (digit 28x28). 

Now with a better transformation to keep distance function.

Isomap

LLE (collapse many points to one)

T-SNE:

So now, what is better in the context of unlabeled data?

 or 

You can now use t-SNE to visualize millions of objects. Very exciting!  http://arxiv.org/abs/1301.3342

Simplicity's impact on conversion

What drives online business is conversion. What is the biggest driver of increase in conversions?

• More users landing (PPC)
• Payment simplicity

What is the point of increasing the number of users landing to your site if you don't start by optimizing your biggest show stopper: the payment funnel.

Digital currency such as bitcoin can simplify this funnel by making it one step, not 4. 

So which currency is less friction?

Does simplicity really increase conversion:

• Case studies
• Skype Boosts Homepage Conversion Rate with Radical Simplicity
• Signups increased by 60% after actually removing the signup form ...
• Simplicity is the ultimate sophistication
• Frequency and Simplicity Drive Conversion
• Some numbers: 
• Apps sales conversion: iphone = 67% vs 34% android: why? payment simplicity is the top reason (credit card is not optional)

Why MBA aren't design for startup?

Why standard MBA don't bring any value to startup is quite simple, they are trained to be successful in a big corporation not in a struggling startup in the early stage.

Information theory applied to business

If you want to validate a business need, you have to master information theory. 

#1 Evaluating people feedback
        - Indifference = Nice to Have = No value
        - Hate or Desire = High Information = High potential

Potential is proportional to reaction, good or bad. Normal reaction is a sign of nice to have which means no value.

#2 Value
    - Ask = Little value (nice to have)
    - Pain = High Value
    - Observe = a business opportunity

Never ask people want the want, observe them and focus on their pain.


#3 Don't forget: Benefits >>Cost  


Last, there is no business if the benefits aren't significantly higher then the cost.
