, i.e. gt,i=gt,i+n (0,σ2t) The variance of the Gaussian error requires annealing: σ2t=η (1+t) γ increasing the random error on the gradient increases the robustness of the model, even if the initial parameter values are not chosen well and is suitable for training in a particularly deep-seated network. The reason for this is that increasing random noise is more likely to jump over local extreme points and find a better local extremum, which is more common in deep networks. Summary in the above
Machine learning Notes (i)Today formally began the study of machine learning, in order to motivate themselves to learn, but also to share ideas, decided to send their own experience of learning to the Internet to let everyone share.Bayesian learningLet's start with an exampl

Once you have mastered the basics of mathematics, your understanding of these models can easily transcend the formula itself.The difference between deep knowledge and shallow knowledgeBean leaves think that when we learn knowledge, we should learn to differentiate, what is deep knowledge (knowledge), what is shallow knowledge (shallow knowledge).Some knowledge is shallow knowledge, only need to remember to know. But
-party library, without organic integration, the corresponding learning costs will be higher. Python is faster than R. Python can directly deal with the data on the G, R No, r analysis data need to first through the database to transform big data into small data (through GroupBy) to the R for analysis, so R can not directly analyze the behavior of the list, can only analyze statistical results. Python's advantage lies in its glue language characterist

Hello everyone, I am mac Jiang, first of all, congratulations to everyone Happy Ching Ming Festival! As a bitter programmer, Bo Master can only nest in the laboratory to play games, by the way in the early morning no one sent a microblog. But I still wish you all the brothers to play happy!

mathematical expression was unfolded using Taylor's formula, and looked a bit ugly, so we compared the Taylor expansion in the case of a one-dimensional argument.You know what's going on with the Taylor expansion in multidimensional situations.in the [1] type, the higher order infinitesimal can be ignored, so the [1] type is taken to the minimum value,should maketake the minimum-this is the dot product (quantity product) of two vectors, and in what case is the value minimal? look at the two vec

learning (temporal difference learning)In the case of enterprise Data application, the most commonly used is the model of supervised learning and unsupervised learning. In the field of image recognition, semi-supervised learning is a hot topic because of the large number of
systems and robot control. Common algorithms include q-learning and time difference learning (temporal difference learning). In the case of enterprise Data application, the most commonly used is the model of supervised learning and unsupervised learning. In the field of ima
argues that this limitation makes the attention mechanism completely unable to complete the corresponding learning function in some tasks. Whether this limitation can be broken. The article thinks that acitve memory mechanism can break the limitation of attention. In short, Active memory is decoding this step to rely on and access all memory, each step decoding the memory is different. Of course, this mech

thorough search. Many greedy algorithms are like this, as will be mentioned later. Decision Tree Algorithm. The previous inductive bias is called Limited offsetThe latter is called Preferred offset. When studying other inductive inference methods, it is necessary to keep in mind the existence and strength of such inductive bias. If an algorithm is more biased, the more inductive it can be, and more instances are not found. Of course, the correctness
