Here I'm wondering about the line [in s_client]
New, TLSv1/SSLv3, Cipher is ECDHE-RSA-AES256-GCM-SHA384

You're apparently using OpenSSL 1.0.2, where that's a basically useless relic. Back in the days when OpenSSL supported SSLv2 (mostly until 2010, although almost no one used it much after 2000), the ciphersuite values used for SSLv3 and up (including all TLS, but before 2014 OpenSSL didn't implement higher than TLS1.0) were structured differently than those used for SSLv2, so it was important to qualify the ciphersuite by the 'universe' it existed in. It has almost nothing to do with the protocol version actually used, which appears later in the session-param decode:

When we split code in c language one of the most important things to notice is to compilation. When code is getting to different files each of the files needs to be compiled separately, this will help in any case of changes to the code since only the changed file would have to be recompiled. The main way to do so is: first create a makefile that includes compiling for each file there is an example for a makefile as such:

Tensorflow ValueError: Dimensions must be equal: LSTM+MDN

Asked 2021-Jun-14 at 19:07

I am trying to make a next-word prediction model with LSTM + Mixture Density Network Based on this implementation(https://www.katnoria.com/mdn/).

Input: 300-dimensional word vectors*window size(5) and 21-dimensional array(c) representing topic distribution of the document, used to train hidden initial states.

Output: mixing coefficient*num_gaussians, variance*num_gaussians, mean*num_gaussians*300(vector size)

x.shape, y.shape, c.shape with an experimental 161 obserbations gives me such:

(TensorShape([161, 5, 300]), TensorShape([161, 300]), TensorShape([161, 21]))

for MDN model , the likelihood for each sample has to be calculated with all the Gaussians pdf , to do that I think you have to reshape your matrices ( y_true and mu) and take advantage of the broadcasting operation by adding 1 as the last dimension . e.g:

QUESTION

How does Elasticsearch aggregate or weight scores from two sub queries ("bool query" and "decay function")

Asked 2021-Jun-13 at 15:43

I have a complicated Elasticsearch query like the following example. This query has two sub queries: a weighted bool query and a decay function. I am trying to understand how Elasticsearch aggregrates the scores from each sub queries. If I run the first sub query alone (the weighted bool query), my top score is 20. If I run the second sub query alone (the decay function), my score is 1. However, if I run both sub queries together, my top score is 15. Can someone explain this?

My second related question is how to weight the scores from the two sub queries?

...

ANSWER

Answered 2021-Jun-13 at 15:43

I found the answer myself by reading the elasticsearch document on the usage of function_score. function_score has a parameter boost_mode that specifies how query score and function score are combined. By default, boost_mode is set to multiply.

Besides the default multiply method, we could also set boost_mode to avg, and add a parameter weight to the above decay function exp, then the combined score will be: ( the_bool_query_score + the_decay_function_score * weight ) / ( 1 + weight ).

How to find and connect the maximum points from each contour line

Asked 2021-Jun-13 at 15:43

How can I find the maximum points of the curves generated by the contour plot, and then connect them?

...

ANSWER

Answered 2021-Jun-13 at 15:43

Extract the index, idx, of the maximum value from each row of array XA
Use idx on T and XA to extract the x-axis and y-axis values.
- Indexing the array is slightly faster than using y = XA.max(axis=1) to get the max XA values.
The shape of XA is (8, 120000), so there are 8 maximums. I'm not certain why only 7 contour lines are showing.
- Use x[:-1] and y[:-1] to not plot the last point.
