i able discretize pandas dataframe columns code: import numpy np import pandas pd def discretize(x, n_scale=1): c in x.columns: loc = x[c].median() # median absolute deviation of column scale = mad(x[c]) bins = [-np.inf, loc - (scale * n_scale), loc + (scale * n_scale), np.inf] x[c] = pd.cut(x[c], bins, labels=[-1, 0, 1]) return x i want discretize each column using parameters: loc (the median of column) , scale (the median absolute deviation of column). with small dataframes time required acceptable (since single thread solution). however, larger dataframes want exploit more threads (or processes) speed computation. i no expert of dask , should provide solution problem. however, in case discretization should feasible code: import dask.dataframe dd import numpy np import pandas pd def discretize(x, n_scale=1): # i'm using 2 partitions example x_dask = dd.from_pandas(x, npartitions=2)

i have method parses currency strings (such "€4.00" or "$14.50"), there parsing error, , throws formatexception . what want do, send string couldn't parsed (threw exception) database. try { string euronumber = "€4.00"; // throw formatexception double parsednumber = double.parse(euronumber, numberstyles.currency); } catch (formatexception ex) { string stringthatthrewtheexception; // should "€4.00" in case // [omitted] sending server logic } is somehow possible? or should use kind of hack? thank in advance. as bugfinder said, can use tryparse: double parsednumber; var result = double.tryparse(euronumber, numberstyles.currency, cultureinfo.currentculture, out parsednumber); if (!result) { // send error } another alternative move string outside of scope of try block: string euronumber = "€4.00"; try { // throw formatexception double parsednumber = double.p

i trying calculate hamming weight of vector in matlab. function hamming_weight (vet_dec) ham_weight = sum(dec2bin(vet_dec) == '1') endfunction the vector is: hamming_weight ([208 15 217 252 128 35 50 252 209 120 97 140 235 220 32 251]) however, gives following result, not want: ham_weight = 10 10 9 9 9 5 5 7 i grateful if me please. you summing on wrong dimension! sum(dec2bin(vet_dec) == '1',2).' ans = 3 4 5 6 1 3 3 6 4 4 3 3 6 5 1 7 dec2bin(vet_dec) creates matrix this: 11010000 00001111 11011001 11111100 10000000 00100011 00110010 11111100 11010001 01111000 01100001 10001100 11101011 11011100 00100000 11111011 as can see, you're interested in sum of each row, not each column. use second input argument sum(x, 2) , specifies dimension want sum along. note approach horribly slow, can see this question . edit for valid, , meaningf

what belongs "character type" in c11 — besides char of course? to more precise, special exceptions character type (for example any object can accessed lvalue expression of character type — see §6.5/7 in c11 standard), concrete types apply? seem apply uint8_t , int8_t stdint.h , guaranteed? on other hand gcc doesn't regard char16_t uchar.h "character type". only char , signed char , unsigned char 1 . the types uint8_t , int8_t , char16_t , or type in form intn_t or charn_t , may or may not synonyms character type. 1 (quoted from: iso/iec 9899:201x 6.2.5 types 15) 3 types char, signed char, , unsigned char collectively called character types.
