I 've been hesitant about How to Write sparse encoding, and I 've looked back and forth several times at ufldl. This is not only an important concept of DL deep learning, but also the pillar of stacked ISA deep feature learning that I have been studying for a long time.
This chapter mainly introduces the main concepts
Write it in front.From the 08 touch python to now, intermittent use, to today Python has become a daily thing processing, scientific research experiments, and even the main language of the project, mainly because of its agility and fast implementation of the ability. Although read some of the Python tutorial, in addition to the original "Python core programming" has been repeatedly looked at, the rest has not seen very can make their own Python level

outputLength. Training instances that has inputs longer than I or outputsLonger than O'll be pushed to the next bucket and padded accordingly.We assume the list is sorted, e.g., [(2, 4), (8, 16)].
Size:number of units in each layer of the model.
Num_layers:number of layers in the model.
Max_gradient_norm:gradients'll is clipped to maximally this norm.
Batch_size:the size of the batches used during training;The model construction is independent of batch_size, so it can beChanged
resulting in the situation just now, if the rule entry after the Hession matrix will not be irreversible), add the rule after the loss function expression is as follows:
The partial-derivative expression at this time is as follows:
The rest of the problem is to use mathematical optimization method to solve, in addition to the mathematical formula to understand Softmax regression is the extension of the logistic regression.
The differences and conditions of use between Softmax regression and K
derivatives) that consists of the slope of each dimension. The derivation formula for one-dimensional function is as follows:When a function has more than one parameter, we call the derivative a partial derivative. The gradient is the vector formed by the partial derivative on each dimension.Most optimized notes (top) finish.Translator Feedback

Iv. selection of AlgorithmsThis step makes me very excited, finally talked about the algorithm, although no code, no formula. Because the tutorial does not want to go deep to explore the details of the algorithm, so focus on the application of the algorithm from the scenario, the shortcomings of the algorithm, how to choose the algorithm to expand vertically.Our training model is generally divided into sup

Okay, stop it. skip it to avoid being scolded. Maybe someone may wonder why I want to introduce myself first. my name is Haishu and the English name is Hetty. my hobby is ...... Okay, stop it. skip it to avoid being scolded.

Because the values in the dictionary may be the same, the returned list can contain duplicate elements.(itervalues) methodThe Itervalues method is used to return the values in the dictionary as iterators.

Used to say, "wine is not afraid of the alley deep" is now "wine is also afraid of the alley deep" because now the bouquet too much, then you need to let your bouquet let the outside world know. This and the outside chain construction is the same reason, this is why to stand outside the optimization of external chain construction reasons.
, to complete the site, must first learn to do Web pages, so must master the HTML, in order to create a site for the future to lay the foundation.
In the learning of HTML I want to learn while doing is the most effective way, of course, this way for learning PHP is also the most effective.
Any element in the HTML to practice, only to understand what the elements will play an effect, you will remember
long time to digest, but as long as you can stick to it, you will find that your use of regular expressions will significantly improve.

couple will re-embark on my C + + tour, previously also read C++primer and other books but not deep understanding, participate in work and then re-examine will have a new experience. In the blog Park also browsed some of the relevant C + + learning advanced articles and some of the recommended books, very inspired. My understanding is one step at a time, as long as the direction is not too late to start.
