多维事务数据库DB的结构为 (ID,AA2,, Anitems),A是DB中的结构化 属性(例如顾客的年龄,职业收入等),而 items是同事务连接的项的集合(例如购物篮 中频繁项集)。每一个 t=(id,aa 2..2 items-t)由两部分信息组成: 维信息(a1,a2man)项集信息。 挖掘过程分为两部分:挖掘维度信息的模 式和从投影的子DB中找出频繁项集

Slide 17.5.1 Streams-a different way of structuring Now, let's look at one example in which changing the computation evaluation model allows us to explore a very different kind of computational problem. Our goal is to show how a smal

The role of abstractions In this lecture, we are going to look at a very different style of creating large systems, a style called object oriented programming. This style focuses on breaking systems up in a different manner than those we have seen before To set the stage for this, we are first going to return to the notion of

Slide 12.1.1 In the last lecture, we introduced mutation as a component of 6001s|cP our data structures We saw for example that set was a Environment mode way of changing the value associated with a variable in our system, and we saw that set-car! and set-cdr! were ways of changing the values of parts of list structure Now, several important things happened when we introduced

Discrete-Time Systems A discrete-time system processes a given input sequence x[] to generates an output sequencey[n] with more desirable properties In most applications, the discrete-time system is a single-input, single-output system:

Z-Transform The DTFT provides a frequency-domain representation of discrete-time signals and LTI discrete-time systems Because of the convergence condition, in many cases. the DTFT of a sequence may not exist As a result, it is not possible to make use of such frequency-domain characterization in these cases
