    Here is the image stoled from guide of torch: https://github.com/soumith/cvpr2015/blob/master/Deep%20Learning%20with%20Torch.ipynb




    First, we must know what is convolution.


    Here is a good example I quoted from http://www.cnblogs.com/ronny/p/ann_03.html: 




    To summary this, the kernel of convolution define the weights of each pixels beside this pixel contributes to the convolution result of this pixel. Different kernel will extract different feature of the image. 


    Feature map means the convolution result of a particular kernel. In a conventional convolution neural network, it will have several kernels in each convolution layer to extract different features.


    After we get a feature map, we need to sub-sample each feature map because this can help to decrease the amount of data we need to process. There are many kinds of sub-sampling: mean-pooling, max-pooling and stochastic-pooling. Mean-pooling has two tuneable parameters which are trainable parameter and trainable bia. For example, we take the data a window of 2x2 and add them together, then we multiply the result with the trainable parameter and add with the trainable bia. '结果通过sigmoid函数计算。可训练系数和偏置控制着sigmoid函数的非线性程度。如果系数比较小,那么运算近似于线性运算,亚采样相当于模糊图像。如果系数比较大,根据偏置的大小亚采样可以被看成是有噪声的“或”运算或者有噪声的“与”运算。'[1]


    The second kind of sub-sampling is max-pooling. Max-pooling has no learnable parameter. Because what it is doing is to return the maximum pixel of each window. The last kind is stochastic-pooling. First, it will give each pixel a possibility according to their value and calculate the expectation. 在平均意义上,与mean-pooling近似,在局部意义上,则服从max-pooling的准则。[2]


    In general, sub-sampling can perform as a process of extraction feature.


    Look at the image I posted at the beginning, we can see that the deeper convolution layer will have more convolution kernel. This is because the data we need to process is less and less, we can extract more features as we want. 这里需要注意的一点是:C3中的每个特征map是连接到S2中的所有6个或者几个特征map的,表示本层的特征map是上一层提取到的特征map的不同组合(这个做法也并不是唯一的)。(看到没有,这里是组合,就像之前聊到的人的视觉系统一样,底层的结构构成上层更抽象的结构,例如边缘构成形状或者目标的部分)。 刚才说C3中每个特征图由S2中所有6个或者几个特征map组合而成。为什么不把S2中的每个特征图连接到每个C3的特征图呢?原因有2点。第一,不完全的连接机制将连接的数量保持在合理的范围内。第二,也是最重要的,其破坏了网络的对称性。由于不同的特征图有不同的输入,所以迫使他们抽取不同的特征(希望是互补的)。[1]


    There are information about C5 and F6 and the RBF output layer, please turn to [1].


    Here is some information about soft-max: 


    Soft-max regression is kind of logistic regression. Typical logistic regression is for 0 or 1 two results. However, for some sceneries, we need more than two classes regression. 


    Here is some content I quoted from http://deeplearning.stanford.edu/wiki/index.php/Softmax%E5%9B%9E%E5%BD%92

    What is the meaning of the “None” in model.summary of Keras?

    在这里插入图片描述
    None means this dimension is variable. The first dimension in a keras model is always the batch size. The batch size will be automatically defined in the fit or predict methods.

    Summary of what static, heap, and stack memory are:

    • A static variable is basically a global variable, even if you cannot access it globally. Usually there is an address for it that is in the executable itself. There is only one copy for the entire program. No matter how many times you go into a function call (or class) (and in how many threads!) the variable is referring to the same memory location.

    • The heap is a bunch of memory that can be used dynamically. If you want 4kb for an object then the dynamic allocator will look through its list of free space in the heap, pick out a 4kb chunk, and give it to you. Generally, the dynamic memory allocator (malloc, new, et c.) starts at the end of memory and works backwards.

    • Explaining how a stack grows and shrinks is a bit outside the scope of this answer, but suffice to say you always add and remove from the end only. Stacks usually start high and grow down to lower addresses. You run out of memory when the stack meets the dynamic allocator somewhere in the middle (but refer to physical versus virtual memory and fragmentation). Multiple threads will require multiple stacks (the process generally reserves a minimum size for the stack).

    When you would want to use each one:

    • Statics/globals are useful for memory that you know you will always need and you know that you don't ever want to deallocate. (By the way, embedded environments may be thought of as having only static memory... the stack and heap are part of a known address space shared by a third memory type: the program code. Programs will often do dynamic allocation out of their static memory when they need things like linked lists. But regardless, the static memory itself (the buffer) is not itself "allocated", but rather other objects are allocated out of the memory held by the buffer for this purpose. You can do this in non-embedded as well, and console games will frequently eschew the built in dynamic memory mechanisms in favor of tightly controlling the allocation process by using buffers of preset sizes for all allocations.)

    • Stack variables are useful for when you know that as long as the function is in scope (on the stack somewhere), you will want the variables to remain. Stacks are nice for variables that you need for the code where they are located, but which isn't needed outside that code. They are also really nice for when you are accessing a resource, like a file, and want the resource to automatically go away when you leave that code.

    • Heap allocations (dynamically allocated memory) is useful when you want to be more flexible than the above. Frequently, a function gets called to respond to an event (the user clicks the "create box" button). The proper response may require allocating a new object (a new Box object) that should stick around long after the function is exited, so it can't be on the stack. But you don't know how many boxes you would want at the start of the program, so it can't be a static.

    Garbage Collection

    I've heard a lot lately about how great Garbage Collectors are, so maybe a bit of a dissenting voice would be helpful.

    Garbage Collection is a wonderful mechanism for when performance is not a huge issue. I hear GCs are getting better and more sophisticated, but the fact is, you may be forced to accept a performance penalty (depending upon use case). And if you're lazy, it still may not work properly. At the best of times, Garbage Collectors realize that your memory goes away when it realizes that there are no more references to it (see reference counting). But, if you have an object that refers to itself (possibly by referring to another object which refers back), then reference counting alone will not indicate that the memory can be deleted. In this case, the GC needs to look at the entire reference soup and figure out if there are any islands that are only referred to by themselves. Offhand, I'd guess that to be an O(n^2) operation, but whatever it is, it can get bad if you are at all concerned with performance. (Edit: Martin B points out that it is O(n) for reasonably efficient algorithms. That is still O(n) too much if you are concerned with performance and can deallocate in constant time without garbage collection.)

    Personally, when I hear people say that C++ doesn't have garbage collection, my mind tags that as a feature of C++, but I'm probably in the minority. Probably the hardest thing for people to learn about programming in C and C++ are pointers and how to correctly handle their dynamic memory allocations. Some other languages, like Python, would be horrible without GC, so I think it comes down to what you want out of a language. If you want dependable performance, then C++ without garbage collection is the only thing this side of Fortran that I can think of. If you want ease of use and training wheels (to save you from crashing without requiring that you learn "proper" memory management), pick something with a GC. Even if you know how to manage memory well, it will save you time which you can spend optimizing other code. There really isn't much of a performance penalty anymore, but if you really need dependable performance (and the ability to know exactly what is going on, when, under the covers) then I'd stick with C++. There is a reason that every major game engine that I've ever heard of is in C++ (if not C or assembly). Python, et al are fine for scripting, but not the main game engine.
