file. Queries on bold-marked tables (MIDS.TBACCT and MIDS.TBACCT-HLDR) refer to remote objects. Table Hjg.iitbl is local to the DB2 II server. Explain will break down this query into several parts. For the part that will use the overlay, mark the word ship. Listing 2 shows an abridged edition of the Explain output. The optimizer marks the subquery #1 as "shipable".

A very simple example of using C # to invoke TensorFlow. 1. Install TensorFlow
First you need to install the Windows version of Tensowflow, use 64-bit python3.5, and if not installed, you need to first install python3.5
Then go to the command line as an administrator and run
Pip Install TensorFlow 2.c# calling code initialization CLE and PYTHON35

interested small partner can pay attention to the next XLA docs and this tensorflow Dev SubmitOn the talkxla:tensorflow of XLA, compiled!Finally, paste some of the XLA performance:Integration of Keras and TensorFlow
Keras is a deep learning framework that can be applied on many platforms, "an API specify for building deep learning models across many".TensorFlow has been in the official TensorFlow support, 1.1 will be tf.keras in tf.contrib,1.2, and will support TensorFlow serving, is not very e
TFs along each edge so we can see how that works: I 've colored the areas influenced by the different edge tessellation factors; the uncolored center part in the middle only depends on the inside TFs. in these images, the u = 0 (yellow) edge has a TF of 2, the V = 0 (green) edge has a TF of 3, the U = 1/W = 0 (pink) edge has a TF of 4, and the V = 1 (quad only,
noise point, which is consistent with the x_data dimension. Fit the mean value 0 and the variance 0.05 normal distribution.Y_data = np. square (x_data)-0.5 + noise # y = x ^ 2-0.5 + noise
Define placeholders x and y as input neural network variables.

(), generate numbers from 140 to 220, you will find that each height segment of the number of people is the same, it is more boring, such a world is also different from our habits, The reality should be particularly high and very short, in the middle of the number of people, which requires random functions to conform to the normal distribution.Tf.truncated_normal (Shape, mean=0.0, stddev=1.0, Dtype=tf.float32, Seed=none, Name=none)Outputs a random value from a truncated normal distribution, as
Test instructions: There is a cow to prove that the cow is not stupid, so take some cow partners to prove themselves. Cows have an IQ and a sense of humor, both of which can be negative (difficult here), requiring that all cows ' IQ and/or sense of humor are not negative. The maximum value of the sum of the two.Idea: Each cow can be brought or not on, is 01 knapsack problem. But the problem is that there is no obvious knapsack capacity limit, but there are some limitations that are not negative,
Before parsing the Lucene search process, it is necessary to separate the Lucene score formula and describe the meaning of each part. Because of Lucene's search process, a very important step is to gradually calculate the scores of each part.
Lucene's scoring formula is very complex, as follows:
Before derivation, we will introduce the meaning of each part one by one:
T: Term. The Term here refers to the Term that contains the domain information, that is, the title: hello and content: hello
suitable for image samples. Note that you want to set the Uint8 type before you turn it into a string. Read a sample
Next, we define a function, create the "read a sample from file" operation, and return the result tensor.
def read_single_sample (filename):
# Read the sample example each member A,b,c
# ...
Return a, B, c
First create a read file queue, using TF. Tfrecordreader reads a serialized sample from the file queue.
# Read the
code, and deploy the Lucene-driven full-text search cluster. You will find it works very well, fast and accurate.Then you wonder: Why is Lucene so awesome?This article, which focuses on Tf-idf,okapi BM-25 and the general relevance score, and the next article (main introduction index) will tell you the basic concepts behind full-text search.CorrelationFor each search query, it is easy to define a "related score" for each document.

TF-IDF is a commonly used weighted technique for information retrieval, which evaluates the importance of words for one of the documents in a file database in text retrieval. The importance of words increases in proportion to the frequency with which it appears in the file, but decreases inversely as it appears in the file dat
that the characteristic dimension of one-hot representation expression is too high, it needs dimensionality reduction. However, this is not the worst of the pit dad's flaws.Bengio in a neural probabilistic language model in 2003, the dimension is too high to cause each study to force the majority of parameters to be changed.Thus the butterfly effect, originally very good parameters, may be because of a small spread error, the change of the mess.In fact, the traditional
